Multidisciplinary approach for the management of term pregnancy complicated by Eisenmenger syndrome / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.

Miocardiopatía periparto: revisión de la literatura / Peripartum Cardiomyopathy

Resumen: La Miocardiopatía Periparto es una patología que se presenta como una insuficiencia cardíaca aguda que aparece en el último mes del embarazo o los primeros 5 meses post parto, en ausencia de otra causa identificable. A pesar de ser más frecuente en países Afrodescendientes, el efecto migratorio ha provocado un aumento en su incidencia en los países de América latina, influyendo en la morbimortalidad materna. Si bien su etiología aún no está claramente definida, se han propuesto algunos mecanismos como el aumento del estrés oxidativo, el desequilibrio de la angiogénesis y las reacciones inflamatorias que, en un organismo genéticamente predispuesto, podrían ser los desencadenantes de esta enfermedad. Su manejo aún se considera de soporte, pero se sigue investigando en alternativas terapéuticas que puedan mejorar los resultados a largo plazo. Así, el motivo de esta revisión es evaluar la evidencia disponible hasta el momento, para el enfrentamiento del equipo tratante de estas pacientes.

Abstract: Peripartum Cardiomyopathy is a diseae presenting as acute heart failure that appears in the last month of pregnancy or within 5 months postpartum, in the absence of other identifiable cause. Despite being more frequent in Afro-descendant populations, the migratory effect has caused an increase in its incidence in Latin American countries, influencing maternal morbidity and mortality. Although its etiology is not yet defined, some mechanisms have been proposed such as increased oxidative stress, angiogénesis imbalance and inflammatory reactions that in a genetically predisposed organism, could be the triggers of this disease. Supportive therapy is still the initial management. Therapeutical alternatives that are still being investigated. The main purpose of this review is to evaluate the evidence available to improve the prognosis of the disease.

Paro cardiorrespiratorio en la embarazada y cesárea perimortem / Maternal cardiac arrest and perimortem cesarean delivery

Resumen El paro cardiorrespiratorio (PCR) en la mujer embarazada es una situación infrecuente, grave y de manejo multidisciplinario. La reanimación cardiopulmonar requiere consideraciones y particularidades propias de la embarazada, centradas en la fisiología y la anatomía, teniendo especial consideración la compresión aortocava, la intubación-ventilación difícil, la presencia de estómago lleno y el hecho que hay dos vidas involucradas. Las principales causas de PCR son las hemorrágicas, seguidas de las embólicas, cardiovasculares, anestésicas e infecciosas. Las principales acciones incluyen activación del código azul obstétrico con respuesta rápida para una eventual realización de histerotomía de emergencia oportuna en el mismo sitio evitando el traslado al quirófano, compresiones torácicas de buena calidad, desviación manual uterina a la izquierda, intubación endotraqueal y manejo avanzado de la vía aérea, todo esto con el fin de mejorar la sobrevida materno-fetal. La cesárea perimortem es un pilar en el manejo, favoreciendo el desenlace materno y eventualmente el fetal. Se debe realizar a los 4 minutos de una reanimación cardiopulmonar no exitosa. Sin embargo, aún hay retardo a la hora de indicarla, por lo que se debe incentivar el entrenamiento, la simulación en resucitación cardiopulmonar materna y las guías clínicas para todo el personal involucrado en la atención de pacientes obstétricas.

Abstract Cardiopulmonary arrest is a rare event during pregnancy and labor. It involves many subspecialties and allied health providers. Besides it requires knowledge of maternal physiology as it relates to resuscitation, particularly aortocaval compression, difficult airway, full stomach and the fact that there are two lives involved. The most frequent causes of cardiac arrest during pregnancy include bleeding, followed by embolism, infection, anesthesia complications and heart failure. The main steps required are: obstetric code activation with appropriate response for performing timely emergent hysterotomy in the same place avoiding the transfer to operating room; good-quality chest compressions; manual uterine displacement to the left, advanced pharmacological and airway management; and optimal care after resuscitation to improve maternal and fetal outcomes. Although current recommendations for maternal resuscitation include the performance of perimortem cesarean section after four minutes of unsuccessful cardiopulmonary resuscitation, deficits in knowledge about this procedure are common. Therefore, training and available evidence-based guidelines should be put in place for all obstetric caregivers.

Síndrome de Eisenmenger y embarazo - reporte de 2 casos / Eisenmenger's and pregnancy syndrome - 2 case report

RESUMEN El síndrome de Eisenmenger es una patología del sistema vascular pulmonar, que se caracteriza por un incremento de las resistencias en los vasos sanguíneos pulmonares, en pacientes con antecedentes de cardiopatía con comunicación entre la circulación pulmonar y circulación sistémica. Este síndrome en la mujer embarazada representa un alto índice de morbilidad y mortalidad tanto para la madre como para el feto; los síntomas que presentan surgen como consecuencia de los cambios fisiológicos en el sistema cardiovascular y hematopoyético. Es un desafío para el obstetra el manejo de estas pacientes idealmente debe ofrecerse asesoría preconcepcional, y valoración por cardiología; si no es posible, se realizará evaluación del riesgo desde el primer control prenatal. El mejor tratamiento consiste en oxigenoterapia, medicamentos vasodilatadores, y anticoagulantes, logrando disminuir el porcentaje de pobres desenlaces materno-fetales. Es de vital importancia definir el momento del nacimiento con el fin de tomar las medidas terapéuticas necesarias para evitar complicaciones, además se requiere de un manejo multidisciplinario, incluido el apoyo por una unidad de cuidado intensivo dado la alta probabilidad de complicaciones asociadas a esta patología.

ABSTRACT Eisenmenger syndrome is a pathology of the pulmonary vascular system, which is characterized by an increase in resistance of the pulmonary blood vessels in patients with a history of heart disease with communication between the pulmonary circulation and the systemic circulation. This syndrome in pregnant women represents a high morbidity and mortality rate for both the mother and the fetus. The symptoms that arise are a consequence of the physiological changes in the cardiovascular and hematopoietic system. The management of these patients is a challenge for the obstetrician; ideally, preconception counseling and cardiology assessment should be offered and if this is not possible, risk assessment should be carried out from the first prenatal control. The best treatment consists of oxygen therapy, vasodilating agents, and anticoagulant medications with the goal of reducing the percentage of poor maternal-fetal outcomes. It is vitally important to define the time of birth in order to take the necessary therapeutic measures to avoid complications. In addition, multidisciplinary management and an intensive care unit are required due to the high probability of complications associated with this pathology.

Enfermedades cardio-metabólicas en el embarazo: revisión sobre diagnóstico, tratamiento y proyección del riesgo cardiovascular a largo plazo / Cardio-metabolic diseases in pregnancy: a review on diagnosis, treatment and projection of long-term cardiovascular risk

Las enfermedades cardiovasculares representan la mayor causa de morbimortalidad a nivel mundial. Si bien presenta un descenso en la población general, en las mujeres tiende a mantenerse estable la prevalencia de enfermedad coronaria. Varios factores propios de la mujer predisponen a que esto ocurra, incluyendo el embarazo, mediado tanto por los cambios hematológicos y cardiovasculares característicos de la gestación; como por patologías asociadas, principalmente trastornos hipertensivos del embarazo y diabetes gestacional. Su presencia se ha asociado fuertemente a la aparición a futuro de otras patologías de alto riesgo cardiovascular como hipertensión crónica, dislipidemia y diabetes mellitus. Dado el impacto que esto representa, se hace imperante la identificación de grupos de alto riesgo y la implementación de medidas preventivas, así como de diagnóstico precoz y tratamientos adecuados con el fin de disminuir complicaciones materno-fetales en las etapas perinatal y posparto.

Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Although there is a decrease in general population, the prevalence of coronary heart disease remains stable in women. Several factors typical of womenkind predispose to cardiovascular disease, including pregnancy, mediated by hematological and cardiovascular changes characteristic of it; and by associated pathologies, mainly hypertensive disorders and diabetes. The presence of these diseases has been strongly associated with future presence of other conditions of high cardiovascular risk such as chronic hypertension, dyslipidemia and diabetes mellitus. Given this impact, the identification of high-risk groups and the implementation of preventive measures, as well as early diagnosis and adequate treatment in order to reduce both maternal and fetal complications in perinatal and postpartum stages becomes imperative.

Peri-operative management of a pregnant patient with hereditary angioedema submitted to a cesarean-section: case report / Abordagem perioperatória de grávida com angioedema hereditário submetida a cesariana: relato de caso

Abstract Hereditary angioedema is an autosomal dominant disorder, presenting as sudden and recurring episodes of variable severity of subcutaneous and mucosa edema that may occur spontaneously or in response to triggers. There are three knwon types of hereditary angioedema. The disorder is caused by decrease in the plasma level or change in the functional capacity of C1 inhibitor, with increase in bradykinin and in vascular permeability, and consequent edema. Several measures are required in the perioperative period in order to avoid an acute attack. Prophylaxis should be carried out throughout pregnancy before any surgical procedure, before dental procedures, upon airway handling, on patients with previous episodes of angioedema, and when there are significant changes in volemia. The literature is scarce in regard to the association between hereditary angioedema and pregnancy. We describe a successful case of a pregnant patient with type I hereditary angioedema submitted to a C-section.

Resumo O angioedema hereditário é uma doença autossômica dominante, que se manifesta por crises súbitas, recorrentes e de gravidade variável de edema subcutâneo e submucoso, que podem ocorrer espontaneamente ou em resposta a gatilhos. São conhecidos três tipos de angioedema hereditário. A doença é condicionada por diminuição do nível plasmático ou alteração da capacidade funcional do inibidor de C1, com aumento da bradicinina e da permeabilidade vascular, com consequente edema. Várias medidas devem ser tomadas no período perioperatório de forma a evitar uma crise aguda. A profilaxia deverá ser realizada durante a gravidez antes de qualquer procedimento cirúrgico, antes de procedimentos dentários, quando existe manuseamento da via aérea, nos doentes com episódios prévios de angioedema e quando há alterações significativas da volemia. A literatura é escassa no que que diz respeito à associação de angioedema hereditário e gravidez. Descrevemos um caso de sucesso de uma grávida com angioedema hereditário tipo I submetida a cesariana.

Ruptured renal artery aneurysm in a pregnant woman: case report and literature review / Ruptura de aneurisma de artéria renal em gestante: relato de caso e revisão da literatura

Abstract Renal artery aneurysms (RAAs) are rare and usually asymptomatic; ~ 90% of them are unilateral. Once diagnosed during pregnancy, they may rupture, presenting a high maternal-fetal risk. The present study reports the case of a 32-year-old pregnant woman with a 30-week gestational age and a ruptured unilateral RAA.

Resumo Os aneurismas de artéria renal (AAR) são raros, normalmente assintomáticos, e ~ 90% dos casos são unilaterais. Uma vez diagnosticados durante a gestação, estes podem se tornar predisponentes a rotura e apresentar elevado risco materno-fetal. O presente artigo relata o caso de uma gestante de 32 anos, com idade gestacional de 30 semanas e quadro de AAR unilateral roto.

Manejo terapéutico y diagnóstico en equipo multidisciplinario y resultados obtenidos en gestantes con cardiopatía orgánica / Diagnostic and therapeutic management and clinical outcome by a multidisciplinary team in pregnant women with heart disease

Las enfermedades cardiovasculares afectan aproximadamente al 2% de las mujeres embarazadas, por lo que suponen un aumento del riesgo tanto para la madre como para el feto. El embarazo y el parto producen cambios fisiológicos sustanciales que requieren de una adecuada adaptación del sistema cardiovascular. Estos cambios fisiológicos que son muy bien tolerados en las gestantes sin cardiopatía, exponen a la mujer con enfermedad cardiovascular a eventos clínicos significativos. Este es un trabajo descriptivo, retrospectivo, de casos consecutivos de pacientes que acudieron a la División de Medicina Cardiovascular, del Hospital de Clínicas en un período comprendido entre Agosto de 2013 a Junio de 2014. Incluye a 5 pacientes embarazas y portadoras de cardiopatías conocidas o desconocidas. La edad promedio fue de 27 años, rango etario de 17 a 36 años. La edad gestacional al momento de la consulta fue de 34 semanas por fecha de última menstruación, menor edad gestacional 30 semanas y mayor edad gestacional 38 semanas. El síntoma principal de consulta fue la disnea (100%), edema de miembros inferiores en 3 pacientes (60%), y palpitaciones en 2 pacientes (40%). El manejo diagnóstico y terapéutico conjunto con un seguimiento detallado y adecuado por un equipo multidisciplinario de cardiólogos, clínicos, ginecólogos, anestesiólogos y cirujanos cardiovasculares facilitan una buena evolución clínica y un desenlace exitoso del embarazo y parto de la gestante con la cardiopatía orgánica. Como resultado de este manejo multidisciplinario todos los recién nacidos tuvieron buena evolución durante su permanencia en la unidad de cuidados intensivos sin inconvenientes(AU)

Heart diseases affect approximately 2% of pregnant women increasing the risk of the mother and the child. The pregnancy and the delivery produce substantial physiological changes requiring an adequate adaptation of the cardiovascular system. These changes, which are well tolerated by pregnant women without heart disease, expose the pregnant women with heart disease to significant clinical events. This is a descriptive, retrospective study of consecutive cases in the Division of Cardiovascular Medicine of the Hospital de Clínicas between August 2013 and June 2014. It includes five pregnant women with known or unknown heart disease at the time of consultation. The average age was 27 years old (17 to 36 years old). The average gestational age was 34 weeks (30 to 38 weeks). The main symptom at consultation was dyspnea (100%), edema of inferior limbs (60%), and palpitations (40%). The joint diagnostic and therapeutic management with a detailed and adequate follow-up by a multidisciplinary team of cardiologists, physicians, gynecologists, anesthesiologists, and cardiac surgeons facilitated a good clinical outcome and a successful completion of the pregnancy and delivery of the pregnant women with heart disease. As a result of the work of this multidisciplinary team, all the newborns had good evolution during their stay at the intensive care unit without any difficulties(AU)

Manejo anestesiológico de pacientes con trastorno hipertensivo del embarazo / Anesthesiological management of patients with hypertensive disorder of pregnancy

Los Trastornos hipertensivos del embarazo (THE) contribuyen a la morbimortalidad materna y fetal. En Chile sigue siendo la 2ª causa de muerte materna. Las Sociedades Estadounidense (ACOG) y Canadiense (SOGC) de Ginecología y Obstetricia publicaron una actualización de sus guías de hipertensión en el embarazo, destacando cambios en definiciones y criterios diagnósticos. Se revisan las modificaciones con el objetivo de orientar el manejo anestesiológico de estas pacientes. Los THE se pueden clasificar en múltiples categorías, destacándose la preeclampsia. Ya no es requisito la proteinuria como criterio diagnóstico. Los signos de severidad afectan el pronóstico y deben ser pesquisados. Se recomienda la interrupción del embarazo a las 37 semanas, en ausencia de signos de severidad. La vía del parto es determinada por las condiciones obstétricas de la paciente. El manejo anestésico engloba el cuidado de crisis hipertensivas, convulsiones, analgesia en el trabajo de parto y anestesia para cesárea. Se recomienda la analgesia epidural precoz en el trabajo de parto y anestesia espinal para cesárea. No se recomienda la administración libre de fluidos endovenosos ni la monitorización invasiva, por el riesgo aumentado de complicaciones.

Hypertensive Disorders of Pregnancy (HDP) contribute to maternal and fetal morbidity and mortality. In Chile, it is still the second leading cause of maternal death. The American (ACOG) and Canadian (SOGC) Societies of Obstetrics and Gynecology published an update of their hypertension guidelines in pregnancy, highlighting changes in definitions and diagnostic criteria. Modifications are revised in order to guide the anesthetic management of these patients. HDP can be classified into multiple categories, highlighting preeclampsia. Proteinuria is no longer required as diagnostic criteria. Severity features affect prognosis and should be actively searched. Interruption of pregnancy at 37 weeks is recommended, in the absence of signs of severity. Delivery should be determined by the obstetric conditions. Anesthetic management includes care of hypertensive crises, seizures, analgesia for labor and anesthesia for cesarean section. Early epidural analgesia is recommended in labor and spinal anesthesia for cesarean section. Intravenous fluids and invasive monitoring are not recommended due to increased complications risks.

Eisenmenger syndrome in pregnancy

Abstract Eisenmenger syndrome is very rare in pregnant women. Debates remain concerning the management of Eisenmenger syndrome in this patient population and the prognosis is unclear in terms of maternal and fetoneonatal outcomes. Epidural analgesia is preferred for Cesarean section as it alleviates perioperative pain and reduces the pulmonary and systemic vascular resistances. Maternal mortality in the presence of Eisenmenger syndrome is reported as 30-50% and even up to 65% in those with Cesarean section. The major causes of death could be hypovolemia, thromboembolism and preeclampsia. Pregnancy should ideally be avoided in a woman with Eisenmenger syndrome concerning the high maternal mortality rate and probable poor prognosis of the baby. A short labour and an atraumatic delivery under epidural block are preferred in the women with a strong desire of pregnancy. The purpose of this article is to discuss the debates of Eisenmenger syndrome in pregnancy and the possible resolutions.

Cardiac myxoma in pregnancy: a comprehensive review / Mixoma cardíaco na gravidez: revisão abrangente

AbstractObjective:Cardiac myxoma in pregnancy is rare and the clinical characteristics of this entity have been insufficiently elucidated. This article aims to describe the treatment options and the risk factors responsible for the maternal and feto-neonatal prognoses.Methods:A comprehensive search of the literature of cardiac myxoma in pregnancy was conducted and 44 articles with 51 patients were included in the present review.Results:Transthoracic echocardiography was the most common diagnostic tool for the diagnosis of cardiac myxoma during pregnancy. Cardiac myxoma resection was performed in 95.9% (47/49); while no surgical resection was performed in 4.1% (2/49) patients (P=0.000). More patients had an isolated cardiac myxoma resection in comparison to those with a concurrent or staged additional cardiac operation [87.2% (41/47) vs. 12.8% (6/47), P=0.000]. A voluntary termination of the pregnancy was done in 7 (13.7%) cases. In the remaining 31 (60.8%) pregnant patients, cesarean section was the most common delivery mode representing 61.3% and vaginal delivery was more common accounting for 19.4%. Cardiac surgery was performed in the first, second and third trimester in 5 (13.9%), 14 (38.9%) and 17 (47.2%) patients, respectively. No patients died. In the delivery group, 20 (76.9%) neonates were event-free survivals, 4 (15.4%) were complicated and 2 (7.7%) died. Neonatal prognoses did not differ between the delivery modes, treatment options, timing of cardiac surgery and sequence of cardiac myxoma resection in relation to delivery.Conclusion:The diagnosis of cardiac myxoma in pregnancy is important. Surgical treatment of cardiac myxoma in the pregnant patients has brought about favorable maternal and feto-neonatal outcomes in the delivery group, which might be attributable to the shorter operation duration and non-emergency nature of the surgical intervention. Proper timing of cardiac surgery and improved cardiopulmonary bypass conditions may result in even better maternal and feto-neonatal survivals.

ResumoObjetivo:Mixoma cardíaco durante a gravidez é raro e as características clínicas dessa entidade não foram suficientemente esclarecidas. Este artigo tem como objetivo descrever as opções de tratamento e os fatores de risco responsáveis pelo prognóstico materno e fetal-neonatal.Métodos:Foi realizada uma pesquisa abrangente na literatura sobre mixoma cardíaco durante a gravidez e 44 artigos com 51 pacientes foram incluídos na presente revisão.Resultados:Ecocardiografia transtorácica foi a ferramenta de diagnóstico mais comum para o diagnóstico de mixoma cardíaco durante a gravidez. Ressecção do mixoma cardíaco foi realizada em 95,9% (47/49); enquanto não foi realizada ressecção cirúrgica em 4,1% (2/49) dos pacientes (P=0,000). Mais pacientes tiveram ressecção isolada do mixoma cardíaco em comparação com aqueles com operação cardíaca concomitante ou adicional [87,2% (41/47) vs. 12,8% (6/47), P=0,000]. A interrupção voluntária da gravidez foi feita em 7 (13,7%) casos. Nas restantes 31 (60,8%) pacientes grávidas, a cesariana foi o modo de parto mais comum, representando 61,3% e parto vaginal contabilizou 19,4%. A cirurgia cardíaca foi realizada no primeiro, segundo e terceiro trimestre em 5 (13,9%), 14 (38,9%) e 17 (47,2%) pacientes, respectivamente. Nenhuma paciente morreu. No grupo de parto, 20 (76,9%) recém-nascidos sobreviveram livres de eventos, 4 (15,4%) tiveram complicações e 2 (7,7%) morreram. Os prognósticos neonatais não diferiram entre os modos de parto, opções de tratamento, tempo de cirurgia cardíaca e sequência de ressecção mixoma cardíaco em relação ao parto.Conclusão:O diagnóstico de mixoma cardíaco durante a gravidez é importante. Tratamento cirúrgico de mixoma cardíaco em pacientes grávidas trouxe resultados favoráveis para as mães e os neonatos no grupo de parto, o que pode ser atribuído à duração mais curta da operação e à natureza não emergencial da intervenção cirúrgica. O momento adequado da cirurgia cardíaca e melhoria das condições de circulação extracorpórea podem resultar em sobrevivência materna e do feto-neonato ainda melhor.

Hipertensión portal en el embarazo: presentación de un caso / Portal hypertension in pregnancy: report of a case

La coexistencia de embarazo y enfermedad hepática representa una situación clínica compleja. Durante el embarazo se desarrolla un estado hipervolémico debido a un flujo esplácnico incrementado, que contribuye a mayor presión portal transmitida a las venas colaterales que incrementan el riesgo de hemorragia varicosa en este grupo de pacientes. Se reporta el caso de una paciente de 39 años en el sexto embarazo y sin ningún antecedente médico previo que presenta hipertensión portal pre-sinusoidal y que gracias al manejo multidisciplinario adecuado, tuvo un parto sin complicaciones. Se revisa la literatura pertinente al caso.

The coexistence of pregnancy and liver disease represents a complex clinical situation. Pregnancy develops hypervolemic state due to increased splachnic blood flow, which contributes to increased portal pressure transmitted to collateral veins that increase the risk of variceal bleeding in these patients. We report the case of a 39 years old patient in the sixth pregnancy and without any previous medical history that presented pre-sinusoidal portal hypertension, and thanks to appropriate multidisciplinary management had an uncomplicated delivery. We review the literature relevant to the case.

Resultado perinatal em mulheres portadoras de hipertensão arterial crônica: revisão integrativa da literatura / Perinatal outcome in women suffering from chronic hypertension: literature integrative review / Resultado perinatal en mujeres que sufren de hipertensión crónica: revisión integradora de la literatura

Objetivou-se identificar as principais complicações relativas à Hipertensão Arterial Crônica observadas em mulheres gestantes e conhecer a evolução nos padrões de riscos dos resultados perinatais em duas décadas. Realizou-se uma revisão integrativa da literatura com abrangência temporal entre os anos de 1990 e 2010, nas bases de dados LILACS, SciELO e MEDLINE. Entre os resultados, observou-se que gestantes hipertensas crônicas apresentaram pré-eclâmpsia sobreposta (20% a 78%), restrição do crescimento fetal (8,5% a 30,7%), prematuridade (32,4% a 86,4%), cesárea (69,2%), descolamento prematuro da placenta (3,75% a 8,4%), óbito fetal (9,5% a 27,2%), complicações cardiovasculares, renais e pulmonares maternas. Conclui-se que a associação entre hipertensão crônica e gestação mostra forte risco para complicações maternas e perinatais, principalmente quando associados à severidade e etiologia da hipertensão, não mostrando evolução no decorrer das duas décadas pesquisadas sobre o resultado perinatal.

The study aimed to identify patterns in the evolution of risk of perinatal outcomes of pregnant women with chronic hypertension in order to compare the results of the pregnancy outcome. It was held an integrative literature with time span between the years 1990 and 2010, in the databases LILACS, SciELO and MEDLINE. As results, it was observed that pregnant women had chronic hypertensive superimposed preeclampsia (20% to 78%), fetal growth restriction (8.5% to 30.7%), prematurity (32.4% to 86.4%), cesarean section (69 2%), placental abruption (3.75% to 8.4%), fetal death (9.5% to 27.2%), cardiovascular complications, maternal kidney and lung. We conclude that the association of chronic hypertension and pregnancy shows strong risk for maternal and perinatal complications, especially when associated with the severity and etiology of hypertension, showing no trend during the two decades studied on perinatal outcome.

Objetivó-se identificar los patrones en la evolución del riesgo de resultados perinatales de las mujeres embarazadas con hipertensión crónica con el fin de comparar los resultados de la evolución del embarazo. Realizó-se una revisión integradora de la literatura, con lapso de tiempo entre los años 1990 y 2010, en las databases LILACS, SciELO y MEDLINE. En los resultados, fue observado que las mujeres embarazadas con hipertensión crónica apresentaran preeclampsia superpuesta (20% a 78%), restricción del crecimiento fetal (8,5% a 30,7%), prematuridad (32,4% a 86,4%), cesárea (69 2%), desprendimiento abrupto de la placenta (3,75% a 8,4%), muerte fetal (9,5% a 27,2%), complicaciones cardiovasculares, renales y pulmonares materna. Concluye-se que la asociación de hipertensión crónica y embarazo presenta riesgo importante para complicaciones maternas y perinatales, especialmente cuando se asocia con la gravedad y etiología de la hipertensión, sin mostrar tendencia a evolución, durante las dos décadas estudiadas, en el resultado perinatal.

Repercusión del embarazo en gestantes con diagnóstico de cardiopatía congénita / Repercussion of pregnancy in women diagnosed with congenital heart disease

Introducción: Las mujeres cardiópatas estuvieron "condenadas" durante muchos años a no poder asumir la maternidad debido al riesgo incrementado de mortalidad materna que el embarazo representaba para ellas, actualmente el 85 porciento o más de estas pacientes sobreviven la edad de 18 años, y muchas, dependiendo del tipo específico de la afectación cardiaca y el grado de corrección que se le pueda realizar, pueden tener una expectativa de vida similar a la población general. Objetivo: describir los resultados perinatales obtenidos en las pacientes embarazadas con diagnóstico de cardiopatía congénita, a partir de la aplicación de un protocolo de trabajo realizado por un grupo multidisciplinario de especialistas. Métodos: se realizó un estudio descriptivo prospectivo transversal, en el que se analizaron factores clínicos y perinatológicos asociados a las gestantes con cardiopatías congénitas, atendidas en el Servicio de Cardiopatía y Embarazo del Hospital Ramón González Coro, en el municipio Plaza, provincia La Habana, en el periodo correspondiente entre el 1ro. de enero de 2000 y el de 31 de diciembre de 2010. Resultados: el 75 porciento, de las pacientes se embarazó antes de los 30 años de edad. El 10,4 porciento, presentó morbilidad de causa obstétrica y entre ellas prevaleció la diabetes gestacional. Hubo agravamiento de la clasificación funcional I al inicio del embarazo a II y III al momento del parto. No hubo recién nacido con diagnóstico de cardiopatía congénita. Conclusión: Con la aplicación del Protocolo de Atención a la Gestante Cardiópata se han logrado resultados perinatales alentadores en la gestante con cardiopatía congénita

Introduction: for many years, the women presenting with heart disease were condemned to not to get pregnant due to the increased risk of maternal mortality caused by it, nowadays the 85 percent or more of these patients survives the 18 years old, and many of them, depending on the type specific of cardiac affection and the degree of a potential correction, may to have a life expectancy similar to general population. Objective: to describe the perinatal results obtained in pregnant patient diagnosed with congenital heart disease, from the implementation of a work protocol conducted by a multidisciplinary group of specialists. Methods: a cross-sectional, prospective and descriptive study was conducted to analyze the clinical and perinatology factors associated with congenital heart diseases seen in the Heart Disease and Pregnancy Service of the Ramón González Coro Hospital of the Plaza municipality of La Habana from January 1, 2000 to December, 31 2010. Results: the 75 percent of patients got pregnants at 30 years old. The 10.4 percent had a morbidity of obstetric cause and among them prevailed the gestational diabetes. There was worsening of functional I classification at onset of pregnancy at II and III at delivery. There was not newborn diagnosed with congenital heart disease. Conclusion: with the implementation of the Protocol of Care to Heart Disease Patient it has been possible to achieve encouraging perinatal results in pregnant presenting with congenital hart disease

Disección aórtica tipo B y embarazo en un síndrome de Marfán: manejo y resultado / Type B aortic dissection and pregnancy in Marfan syndrome

El síndrome de Marfán es una enfermedad autosómica dominante del tejido conectivo, multisistémica y pronóstico determinado por las complicaciones cardiovasculares. Se presenta una paciente de 32 años, multípara, con el diagnóstico conocido de cinco años, posterior a disección aórtica toraco-abdominal (Standford B) y embarazo actual no planificado. Es manejada con betabloqueadores y las imágenes seriadas de aorta muestran disección estable en el segmento entre subclavia izquierda e ilíaca derecha con 41,8 mm en su diámetro mayor, sin comprometer la irrigación de órganos abdominales. Ingresa a las semana 32 para evaluación multidisciplinaria y parto programado. El examen con resonancia nuclear magnética de columna lumbosacra evidenció ectasia dural marcada a nivel de raíz S2. La evaluación fetal demostró un crecimiento en percentil 20 con bienestar hemodinámico y ecocardiografía normal. Previa inducción de madurez pulmonar y con 34+3 semanas, se efectúa cesárea electiva bajo anestesia espinal continua, con nacimiento sin compresión del fondo uterino, esterilización tubaria y postoperatorio inmediato en Unidad Coronaria por 48 horas. La evolución materna es sin incidentes. El recién nacido presentó enterocolitis necrotizante con buena respuesta al tratamiento médico.

Marfan syndrome is a multysistemic an autosomal-dominant disorder of connective tissue and cardiovascular complications determine its prognosis. We present a 32 year-old patient diagnosed five years previously after thoraco-abdominal aneurysm Standford B, and a current unplanned pregnancy. She was treated with beta blockers and evaluated with serial images of the aorta showing a stable thoraco-abdominal aneurysm initiated at the left subclavian artery to the right iliac artery of 41.8 mm at maximum diameter. The patient was hospitalized at 32 weeks to be evaluated in a multidisciplinary team planned delivery. Nuclear Magnetic Resonance on maternal spine detected dural ectasia at S2 and fetal evaluation shows growing at 20 percentile, hemodinamical wellbeing and normal echocardiography. After corticosteroids at 34 +3 weeks a cesarean section with tubal sterilization is performed, with continuous spinal anesthesia, without uterus compression and inmediate postoperative care at the Coronary Unit for 48 hours with satisfactory maternal evolution. The newborn presented a necrotizing enterocolitis at 7 days improving with medical therapy.

Infarto agudo do miocárdio na 31ª semana de gravidez: relato de caso / Myocardial infarction in the 31st week of pregnancy: case report

JUSTIFICATIVA E OBJETIVOS: A ocorrência de infarto agudo do miocárdio (IAM) durante a gravidez é rara. Os autores descrevem o caso de IAM numa grávida de 31 semanas e a importância da existência de uma equipe multidisciplinar para sua abordagem. RELATO DO CASO: Grávida de 31 semanas, com antecedentes de tabagismo, alcoolismo e hipertensão, internada após um episódio de síncope. Na admissão, encontrava-se consciente e assintomática, embora hipotensa. O eletrocardiograma evidenciou marcada elevação do segmento ST em DI, AVL, V1-V6. Pesquisa de enzimas cardíacas foi positiva. O ecocardiograma transtorácico demonstrou redução da contratilidade ventricular esquerda e septal e uma fração de ejeção de 30 por cento. A angiografia revelou oclusão proximal da artéria descendente anterior. Por insucesso da angioplastia por balão, foi colocado um stent metálico. A paciente iniciou terapêutica com b-bloqueadores, aspirina e clopidogrel. Em relação ao parto, optou-se por realizar cesariana eletiva, quatro semanas após o IAM. Suspendeu-se o clopidogrel sete dias antes do parto. A função cardíaca pré-operatória foi otimizada com infusão de levosimendana iniciada no dia anterior. A cesariana decorreu sob bloqueio peridural. O período intraoperatório decorreu sem complicações, à exceção de moderada hipotensão facilmente corrigida com fenilefrina. O índice de Apgar do recém-nascido foi de 9/10. CONCLUSÕES: Este é um dos poucos casos de infarto agudo do miocárdio e angioplastia descritos durante a gravidez. Os autores discutem as decisões tomadas pela equipe multidisciplinar, constituída por anestesiologistas, obstetras, cardiologistas e neonatologistas, notadamente no que se refere à dupla antiagregação plaquetária, ao tipo de parto e à anestesia.

BACKGROUND AND OBJECTIVES: The occurrence of acute myocardial infarction (AMI) during pregnancy is rare. The authors describe the case of MI in a 31-week pregnant woman and the importance of a multidisciplinary team for its approach. CASE REPORT: Thirty-one week pregnant woman with history of smoking, alcoholism and hypertension was admitted after an episode of syncope. On admission she was conscious and asymptomatic, although hypotensive. The electrocardiogram showed marked ST-segment elevation in D1, aVL, V1-V6. The cardiac enzymes were positive. The transthoracic echocardiogram showed reduction in septal and left ventricular contractility and an ejection fraction of 30 percent. Angiography revealed proximal occlusion of the left anterior descending artery. After a non-successful balloon angioplasty, a metallic stent was placed. The patient started therapy with beta-blockers, aspirin and clopidogrel. As for the delivery, we chose to perform a cesarean section four weeks after MI. Clopidogrel was suspended seven days before delivery. The preoperative cardiac function was improved by infusion of levosimendan started the day before. Cesarean section occurred under epidural block. The intraoperative period showed no complications, except for mild hypotension easily corrected with phenylephrine. The Apgar score for the newborn was 9 / 10. CONCLUSIONS: This is one of the few cases of myocardial infarction and angioplasty reported during pregnancy. The authors discuss the decisions taken by the multidisciplinary team consisting of anesthesiologists, obstetricians, neonatologists and cardiologists, particularly with regard to dual antiplatelet therapy, the type of delivery and anesthesia.

JUSTIFICATIVA Y OBJETIVOS: El aparecimiento del infarto agudo del miocardio (IAM), durante el embarazo es raro. Los autores describen el caso de IAM en una mujer embarazada de 31 semanas y la importancia de la existencia de un equipo multidisciplinario para su abordaje. RELATO DEL CASO: Embarazada de 31 semanas, con antecedentes de tabaquismo, alcoholismo e hipertensión, que fue ingresada después de presentar un episodio de síncope. A su llegada, estaba consciente y asintomática, aunque hipotensa. El electrocardiograma mostró una fuerte elevación del segmento ST en DI, AVL, V1-V6. La enzimología cardíaca fue positiva. El ecocardiograma transtorácico acusó una reducción en la contratilidad ventricular izquierda y septal, y una fracción de eyección del 30 por ciento. La angiografía reveló la oclusión proximal de la arteria descendiente anterior. Ya que la angioplastia por balón no tuvo éxito, se colocó un stent metálico. La paciente inició terapéutica con b-bloqueantes, aspirina y clopidogrel. Con relación al parto, se optó por realizar la cesárea electiva 4 semanas después del IAM. Se suspendió el clopidogrel siete días antes del parto. La función cardíaca preoperatoria se optimizó con infusión de levosimedan iniciada el día anterior. La cesárea transcurrió bajo el bloqueo epidural. El período intraoperatorio transcurrió sin complicaciones, con excepción de una moderada hipotensión fácilmente corregida con fenilefrina. El índice de Apgar del recién nacido fue de 9/10. CONCLUSIONES: Este es uno de los pocos casos de infarto agudo del miocardio y angioplastia descritos durante el embarazo. Los autores discuten las decisiones tomadas por el equipo multidisciplinario, que estaba constituido por anestesiólogos, obstetras, cardiólogos y neonatólogos, en lo que se refiere a la doble antiagregación plaquetaria, al tipo de parto y a la anestesia.

Eficácia e segurança com diferentes associações medicamentosas na cardiomiopatia periparto / Efficiency and safety of different drug combinations in peripartum cardiomyopathy

Relata-se o caso de uma paciente de 38 anos, com quadro de insuficiência cardíaca (IC) 30 dias após o parto, tratada de forma convencional. Houve necessidade de mudanças na terapia medicamentosa devido a efeitos colaterais e resposta inadequada da pressão arterial. Discutiram-se, à luz da medicina baseada em evidências, as diversas associações medicamentosas e sua segurança, nos casos de cardiomiopatia periparto (CMPP).

This case study addresses a 38-year-old patient who developed heart failure thirty days after delivery. She received conventional treatment, but changeswere required due to adverse effects and inadequate blood pressure response. In the light of evidencebasedmedicine, various drug combinations andtheir safety are discussed, for cases of peripartum cardiomyopathy.

Implante de cardio-desfibrilador em gestantes com cardiomiopatia hipertrófica / Implantable cardioverter-defibrillator in pregnant women with hypertrophic cardiomyopathy

Descrevemos os casos de duas gestantes portadoras de cardiomiopatia hipertrófica com alto risco de morte súbita arrítmica, que foram submetidas a implante de cardioversor-desfibrilador automático (CDI) no intercurso da gestação. O momento para a realização do procedimento e os cuidados necessários para o implante do CDI durante a gestação são discutidos e foram os principais objetivos deste relato.

We describe the successful implantation of a cardioverter-defibrillator (ICD) in two pregnant women with hypertrophic cardiomyopathy at high risk. The indication of ICD and the necessary care for ICD implantation during pregnancy are discussed and were the main objectives of this case report.

Trombosis de la vena ovárica: Factores de riesgo, diagnóstico y tratamiento / Ovarian vein thrombosis: risk factors, diagnosis and treatment

La trombosis de la vena ovárica es una complicación muy poco frecuente (0.002-0.05%), que se observa en mujeres que presentan un incremento en los factores de coagulación. La principal situación en la que es posible detectar esta complicación es el embarazo, aunque no es la única. Se describe el caso de una mujer de 31 años de edad, gestante de 16 semanas, que presenta un aborto espontáneo séptico complicado con una trombosis de la vena ovárica. Se aprovecha el caso clínico para revisar en la literatura los factores de riesgo, el diagnóstico y el tratamiento de esta inusual patología.

Ovarian vein thrombosis is an uncommon complication (0.002-0.05%) related to hypercoagulated status of women. The most frequent condition associated to ovarian vein thrombosis is pregnancy, but there are other possible causes. We present a case of a 31 year old pregnant woman at 16th week of gestation who had spontaneuos septic abortion complicated with an ovarian vein thrombosis. A discussion of risk factors, diagnostic and treatment options of ovarian vein thrombosis are presented.
