ABSTRACT

OBJETIVO: Describir los resultados inmediatos y alejados de la cirugía coronaria sin circulación extracorpórea (CEC) y comparar los resultados de la estrategia de indicación de la técnica en dos períodos. PACIENTES Y MÉTODOS: Estudio retrospectivo de 428 pacientes intervenidos de cirugía coronaria sin CEC entre 2004 y 2019 en el Hospital Guillermo Grant Benavente. Se dividen en Grupo 1, período 2004-2008 (N=216) y Grupo 2, período 2009-2019 (N=212). Se estudiaron sus características clínicas, resultados quirúrgicos, morbi-mortalidad operatoria y eventos adversos al 31 de junio de 2019 y se compararon los resultados de los grupos a 5 años. RESULTADOS: No hubo diferencias en la distribución por sexo, edad, factores de riesgo y patologías asociadas entre los grupos. Hubo diferencias en las lesiones coronarias entre los Grupos 1 y 2: lesión de un vaso en 45 (20,4%) versus 125 (59%) y tres vasos en 75 (34,5%) versus 19 (9%) respectivamente (p<0,001). El riesgo operatorio por EuroSCORE logístico fue 3,3±3,95 versus 5,4±7,7 (p<0,001). Se confeccionaron 2,3±0,9 anastomosis distales en el Grupo 1 versus 1,3±0,6 en Grupo 2 (p<0,001). La tasa de complicaciones fueron 17,6% en el Grupo 1 y 5,7% en el 2 (p<0,001). La mortalidad operatoria globral fue 4 pacientes (0,9%). El seguimiento comprendió 9,2±3,8 años. La sobrevida a 10 años fue 76,9% y tasa de eventos cardiovasculares mayores 37,6%. No hubo diferencia entre los grupos a los 5 años. CONCLUSIONES: La selección de pacientes con anatomía más favorables o de mayor riesgo operatorio tuvo tasas de sobrevida y eventos similares a los observados con la estrategia menos selectiva a 5 años de seguimiento.


AIM: To describe the immediate and long-term results of off pump coronary artery surgery without cardiopulmonary bypass (OPCABG) comparing the results observed in two consecutive periods. PATIENTS AND METHODS: A retrospective study of 428 patients undergoing OPCABG between 2004 and 2019 at the Guillermo Grant Benavente Hospital. Group 1 patients operated between 2004 - 2008 (N = 216) and Group 2 operated between 2009 and 2019 (N = 212). RESULTS: There were no differences in sex, age, risk factors and co morbidities between groups. There were differences in the number of coronary lesions between groups: one vessel disease in 45 (20.4%) versus 125 (59%) and three vessels in 75 (34.5%) versus 19 (9%) in Group 1 vs Group 2, respectively (p <0.001). The operative risk for logistic EuroSCORE was 3.3 ± 3.95 in Group 1 versus 5.4 ± 7.7 in Group 2 (p <0.001). 2.3 ± 0.9 distal anastomoses were performed in Group 1 compared to 1.3 ± 0.6 in Group 2 (p<0.001). Adverse events occurred in 17.6% o patients in Group 1 compared to 5.7% in Group 2 (p<0.001). Overall, 4 patients died (0.9%). Mean overall survival at 10 years was 76.9% and the rate of major cardiovascular events was 37.6%, no differences being observed between groups. CONCLUSIONS: At 5 years of follow-up the selection of patients with more favorable anatomy or greater operative risk had similar survival rates and events than those observed with the least selective strategy.

ABSTRACT

Abstract Paroxysmal nocturnal hemoglobinuria (PNH) is an ultra-orphan disease. We report the first case in the literature of Off-Pump Coronary Revascularization Using Bilateral Internal Thoracic Arteries in a patient with paroxysmal nocturnal hemoglobinuria. A 36-year-old man came to the emergency department with acute non-ST elevation myocardial infarction (NSTEMI). He presented paroxysmal nocturnal hemoglobinuria diagnosed in 2016. Coronary angiography revealed tripple vessel disease. The conduits used for coronary revascularization were both internal thoracic arteries (left ITA-right ITA [LITA-RITA]). We consider that off-pump coronary artery bypass grafting (OPCABG) using Bilateral Internal Thoracic Arteries (BITA) can be safely performed with low in-hospital mortality and complications rates, even in patient with PNH.

INTRODUCTION: Coronary artery bypass grafting (CABG) without extracorporeal circulation (off pump) is a technical alternative to conventional surgery. There is ongoing controversy about its benefits, safety and results. AIM: To describe immediate and late results of off pump CABG and compare it with conventional surgery. MATERIALS AND METHOD: Descriptive-analytic, study with review of surgical protocols, clinical charts, civil registry for survival and telephonic follow up of patient who underwent CABG in our center between January 2006 and December 2008. In total 658 isolated CABG cases, 466 (70.8%) on pump and 192 (29.2%) off pump. A Propensity Score Matching was used to match off pump CABG patients with those undergoing On Pump CABG. RESULTS: Mortality was 1.0% in off pump and 2.1% in on pump patients (p = 0.411). At follow up: 1.3 and 5 year survival was 97.4%, 95.3% and 92.2% respectively in off pump patients and 97.9%, 96.3% and 92.7% respectively in On Pump patients (p = 0.824). Mayor-adverse-Cardiac-and-Cerebrovascular-events (MACCE) in 28 (17.3%) off pump vs 26 (16.0%) (p = 0.71) on pump, myocardial infarction in 3 (1.9%) off pump vs 6 (3.7%) on pump (p = 0.33), stroke in 6 (3.7%) off pump vs 3 (1.9%) on pump (p = 0.3) and coronary reintervention in 4 (2.5%) off pump vs 3 (1.9%) on pump patients (p = 0.703). Recurrence of angina in 9 (5.6%) off pump vs 10 (6.2%). CONCLUSIONS: In our experience both techniques had similar results.

ABSTRACT

Abstract Objective: To investigate the clinical significance of serum cystatin C (Cys-C) and high-sensitivity C-reactive protein (hs-CRP) in coronary heart disease (CHD) patients undergoing percutaneous coronary intervention (PCI). Methods: One hundred and twenty-eight CHD patients were divided into drug treatment (56 cases) and PCI treatment (72 cases) groups, receiving conventional drug treatment and PCI plus conventional drug treatment, respectively. At admission time and 4 weeks after treatment, the left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter, and left ventricular end systolic diameter were measured. At admission time and 24h, 72h, 1 week, and 4 weeks after treatment, the serum levels of Cys-C and hs-CRP were determined. Results: After 4 weeks of treatment, LVEF in the PCI treatment group was significantly higher than that before treatment (P<0.01) and it was significantly higher than in the drug treatment group at the same time (P<0.01). Cys-C and hs-CRP level in the PCI treatment group were significantly higher than in the drug treatment group 72h and 1 week after treatment (P<0.05 or P<0.01), respectively, but they were significantly lower than in the drug treatment group 4 weeks after treatment (P<0.01). There were obvious interaction effects between grouping factor and time factor in Cys-C (F=3.62, P<0.05) and hs-CRP (F=17.85, P<0.01). Conclusion: Serum levels of Cys-C and hs-CRP are closely related to the heart function in CHD patients undergoing PCI, and they may be used for predicting the outcome of PCI.

ABSTRACT

Abstract Objective: To evaluate the sequential changes of hemodynamic and metabolic parameters in patients who underwent aorta no-touch off-pump coronary artery bypass surgery (OPCAB). Methods: Prospective study involving twenty-seven consecutive patients who underwent aorta no-touch OPCAB. The FloTrac/PreSep/Vigileo™ system (Edwards Lifesciences) was used to continuously record heart rate (HR), mean arterial blood pressure (MABP), central venous pressure (CVP), continuous cardiac index (FCI), stroke volume (SV), stroke volume variation (SVV), and central venous oxygen saturation (ScvO2). The parameters were assessed 5 min before, during and 5 min after each anastomosis (left anterior descending [LAD], posterior descending [PD], obtuse marginal [OM] and diagonal [Dg]). Postoperative lactate was also evaluated. Results: There was no significant change in HR and MABP for all anastomoses, except for MABP during PD grafting (-10.1±2.7 mmHg, P=0.03). There was a significant decrease in ScvO2 only during PD and OM anastomoses (-9.4±0.4, P=0.03; -4.4±0.4, P=0.02; respectively). CVP drop after PD manipulation was strongly associated with a higher lactate during the first hours after surgery (r=-0.82; P=0.001). These hemodynamic changes were transient and entirely recovered after the heart was returned to its anatomical position. No significant differences were observed in FCI, SVV, or the systemic vascular resistance index (SVRI) during all anastomoses, except for a drop in SVRI during PD grafting (-8.03±2.3, P=0.007). SV tended to decrease during the procedure in all territories, but with statistically significant drop only in PD and OM grafting (-10.4±1.2, P=0.02; -13.6±5.1, P=0.007; respectively). Conclusion: Heart displacement for performing aorta no-touch OPCAB is well tolerated, with transient and endurable hemodynamic variations.

ABSTRACT

Abstract Objective: To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods: Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results: 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion: This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

ABSTRACT

Antecedentes: las enfermedades cardiovasculares constituyen la primera causa de morbimortalidad a nivel mundial y nacional; sobresale la enfermedad coronaria. Esto ha contribuido para que el tratamiento quirúrgico de revascularización miocárdica sea considerado como un procedimiento de rutina. Éste es uno de los avances más importantes de la medicina durante el siglo XX. En Bogotá, los registros estadísticos muestran que más del 50% del total de cirugías cardiovasculares corresponde a ella. Objetivo: realizar la caracterización de pacientes que se encuentran en posoperatorio temprano de revascularización miocárdica, quienes presentan cambios fisiológicos en su esfera biológica, secundarios al procedimiento, a nivel neurológico, cardiovascular, respiratorio, gastrointestinal, de eliminación y de la piel. Metodología: se realizó un estudio descriptivo, de seguimiento prospectivo. Se observaron y revisaron las historias clínicas de 151 pacientes en posoperatorio de 48 a 96 horas. La revisión de la historia clínica se realizó por el investigador. Se consignó la información en una hoja de registro de información y se procesó mediante métodos de análisis exploratorio multidimensional: análisis factorial de correspondencias múltiples combinado con el Método Cluster de Clasificación. Resultados: estuvieron relacionados con clases de pacientes de acuerdo con los eventos clínicos presentes en cada uno de los sistemas estudiados donde se evidencia que presentan alteración de los sistemas neurológico, cardiovascular, respiratorio y de la piel. Conclusión: la caracterización de los pacientes en posoperatorio de una revascularización miocárdica permite que el cuidado de enfermería sea enfocado hacia la solución de problemas de los sistemas antes mencionados.


Background: cardiovascular diseases are the leading cause of morbidity and mortality at global and national level; stands out coronary disease. This has contributed to make the surgical treatment of coronary artery bypass grafting being considered a routine procedure. This is one of the most important advances in medicine during the twentieth century. In Bogota, statistical records show that more than 50% of all cardiovascular surgeries corresponds to it. Objective: to characterize patients who are in early postoperative myocardial revascularization, who present physiological changes secondary to procedure, in the biological area at neurological, cardiovascular, respiratory, and gastrointestinal level, elimination system and skin. Methodology: a descriptive study was performed and followed prospectively. The medical records of 151 patients in postoperative 48 to 96 hours were seen and reviewed. The review of the medical history was performed by the researcher. The information was collected on a recording sheet and then recorded and processed by methods of multidimensional exploratory analysis: Multiple correspondence analysis combined with Cluster Classification Method. Results: they were related to the kind of patient according to clinical events present in each of the studied systems where there is evidence of alteration of the neurological, cardiovascular and respiratory systems, and skin. Conclusion: the characterization of patients in postoperative of myocardial revascularization allows nursing care to be focused on solving problems of the aforementioned systems.

ABSTRACT

Remote ischemic preconditioning (RIPre) can prevent myocardial injury. The purpose of this study was to assess the beneficial effects of long-term regular RIPre on human arteries. Forty patients scheduled for coronary artery bypass graft (CABG) surgery were assigned randomly to a RIPre group (n=20) or coronary heart disease (CHD) group (n=20). Twenty patients scheduled for mastectomy were enrolled as a control group. RIPre was achieved by occluding arterial blood flow 5 min with a mercury sphygmomanometer followed by a 5-min reperfusion period, and this was repeated 4 times. The RIPre procedure was repeated 3 times a day for 20 days. In all patients, arterial fragments discarded during surgery were collected to evaluate endothelial function by flow-mediated dilation (FMD), CD34+ monocyte count, and endothelial nitric oxide synthase (eNOS expression). Phosphorylation levels of STAT-3 and Akt were also assayed to explore the underlying mechanisms. Compared with the CHD group, long-term regular RIPre significantly improved FMD after 20 days (8.5±2.4 vs 4.9±4.2%, P<0.05) and significantly reduced troponin after CABG surgery (0.72±0.31 and 1.64±0.19, P<0.05). RIPre activated STAT-3 and increased CD34+ endothelial progenitor cell counts found in arteries. Long-term, regular RIPre improved endothelial function in patients with CHD, possibly due to STAT-3 activation, and this may have led to an increase in endothelial progenitor cells.

ABSTRACT

Introdução: O modelo mais utilizado para predição de mortalidade em cirurgia cardíaca foi recentemente remodelado, mas dúvidas referentes à sua metodologia e desenvolvimento têm sido relatadas. Objetivo: O objetivo deste estudo foi avaliar o desempenho do EuroSCORE II na predição de mortalidade em pacientes submetidos a cirurgia de coronária e/ou valva na instituição. Métodos: Mil pacientes, operados consecutivamente de coronária e/ou valva, entre outubro de 2008 e julho de 2009, foram analisados. O desfecho de interesse foi mortalidade intra-hospitalar. A calibração foi realizada pela correlação entre mortalidade esperada e observada por meio do teste de Hosmer Lemeshow. A discriminação foi calculada pela área abaixo da curva ROC. O desempenho do EuroSCORE II foi comparado com os modelos EuroSCORE e InsCor (modelo local). Resultados: Na calibração, o teste de Hosmer Lemeshow foi inadequado para o EuroSCORE II (P=0,0003) e bom para os modelos EuroSCORE (P=0,593) e InsCor (P=0,184). No entanto, na discriminação, a área abaixo da curva ROC para o EuroSCORE II foi de 0,81 [IC 95% (0,76-0,85), P<0,001]; para o EuroSCORE foi de 0,81 [IC 95% (0,77-0,86), P<0,001] e para o InsCor foi de 0,79 [IC 95% (0,74-0,83), P<0,001], revelando-se adequada para todos. Conclusão: O EuroSCORE II se tornou mais complexo e, à semelhança com a literatura internacional, mal calibrado para predizer mortalidade nos pacientes operados de coronária e/ou valva em nosso meio. Esses dados reforçam a importância do modelo local. .


Introduction: The most widely used model for predicting mortality in cardiac surgery was recently remodeled, but the doubts regarding its methodology and development have been reported. Objective: The aim of this study was to assess the performance of the EuroSCORE II to predict mortality in patients undergoing coronary artery bypass grafts or valve surgery at our institution. Methods: One thousand consecutive patients operated on coronary artery bypass grafts or valve surgery, between October 2008 and July 2009, were analyzed. The outcome of interest was in-hospital mortality. Calibration was performed by correlation between observed and expected mortality by Hosmer Lemeshow. Discrimination was calculated by the area under the ROC curve. The performance of the EuroSCORE II was compared with the EuroSCORE and InsCor (local model). Results: In calibration, the Hosmer Lemeshow test was inappropriate for the EuroSCORE II (P=0.0003) and good for the EuroSCORE (P=0.593) and InsCor (P=0.184). However, the discrimination, the area under the ROC curve for EuroSCORE II was 0.81 [95% CI (0.76 to 0.85), P<0.001], for the EuroSCORE was 0.81 [95% CI (0.77 to 0.86), P<0.001] and for InsCor was 0.79 [95% CI (0.74-0.83), P<0.001] showing up properly for all. Conclusion: The EuroSCORE II became more complex and resemblance to the international literature poorly calibrated to predict mortality in patients undergoing coronary artery bypass grafts or valve surgery at our institution. These data emphasize the importance of the local model. .

ABSTRACT

As complicações mecânicas do infarto agudo do miocárdio são um desfecho catastrófico que alteram o prognóstico do paciente, com elevadas taxas de morbidade e mortalidade. Todas as complicações são secundárias ao evento isquêmico agudo, com necrose de uma área gerando disfunção mecânica cardíaca, que, geralmente, culmina em choque cardiogênico. A ruptura da parede livre do ventrículo esquerdo, a ruptura do septo interventricular, a regurgitação mitral isquêmica e o pseudoaneurisma do ventrículo esquerdo são as complicações mais comuns. São muito pouco diagnosticadas, devendo ser cuidadosamente investigadas na presença de choque cardiogênico e súbita ou progressiva deterioração hemodinâmica. O diagnóstico e a intervenção precisam ser prococes a fim de alterar a evolução desfavorável do paciente e aumentar sua chance de sobrevivência...

ABSTRACT

FUNDAMENTO: O benefício clínico de intervenção coronária percutânea (ICP) para lesões coronárias longas é incerto; além disso, foram levantadas dúvidas questões sobre a sua segurança. OBJETIVO: Avaliar os preditores de eventos cardíacos adversos maiores (ECAM) associados à ICP utilizando Full Metal Jacket (FMJ), definido como a sobreposição de stents farmacológicos (SF) medindo >60 mm de comprimento, para lesões muito longas. MÉTODOS: Foram incluídos 136 pacientes consecutivos com lesões coronárias longas, requerendo FMJ em nosso cadastro de centro único. O desfecho primário incluiu a ocorrência combinada de todas as causas de morte, infarto do miocárdio (IM) e revascularização do vaso alvo (RVA). Variáveis demográficas, clínicas, angiográficas e de procedimento foram avaliadas por meio de análise de regressão de Cox para determinar os preditores independentes de desfecho. RESULTADOS: O comprimento médio do stent por lesão foi de 73,2 ± 12,3 mm e o diâmetro médio do vaso de referência foi de 2,9 ± 0,6 mm. O sucesso angiográfico foi de 96,3%. A ausência de ECAM foi de 94,9% em 30 dias e 85,3% em um ano. No acompanhamento de um ano, a taxa de mortalidade por todas as causas foi de 3,7% (1,5% por mortes cardíacas), a taxa de IM foi de 3,7%, e a incidência de trombose de stent (TS) definitiva ou provável foi de 2,9%. O gênero feminino [risco relativo (RR), 4,40; intervalo de confiança de 95% (IC), 1,81-10,66, p = 0,001) e ICP de artéria coronária não direita (RR, 3,49; p = 0,006; IC 95%, 1,42-8,59) foram preditores independentes de ECAM em um ano. A ausência de eventos adversos em um ano foi maior em pacientes com angina estável submetidos à ICP (RR, 0,33; IC 95% 0,13-0,80, p = 0,014). CONCLUSÕES: A ICP utilizando FMJ com SF para lesões muito longas foi eficaz, mas associada a uma alta taxa de TS em acompanhamento de um ano. No entanto, a taxa de mortalidade cardíaca, IM não relacionado a procedimento, e ECAM foi relativamente baixa. ICP de vaso coronário alvo, apresentação clínica, e gênero feminino são novos fatores clínicos contemporâneos que parecem apresentar efeitos adversos sobre o resultado da ICP utilizando FMJ para lesões longas.


BACKGROUND: The clinical benefit of percutaneous coronary intervention (PCI) for long coronary lesions is unclear; furthermore, concerns have been raised about its safety. OBJECTIVES: To evaluate the predictors of major adverse cardiac events (MACE) associated with PCI using a full metal jacket (FMJ), defined as overlapping drug-eluting stents (DES) measuring >60 mm in length, for very long lesions. METHODS: We enrolled 136 consecutive patients with long coronary lesions requiring FMJ in our single-center registry. The primary endpoint included the combined occurrence of all-cause death, myocardial infarction (MI), and target vessel revascularization (TVR). Demographic, clinical, angiographic, and procedural variables were evaluated using stepwise Cox regression analysis to determine independent predictors of outcome. RESULTS: The mean length of stent per lesion was 73.2 ± 12.3 mm and the mean reference vessel diameter was 2.9 ± 0.6 mm. Angiographic success was 96.3%. Freedom from MACE was 94.9% at 30 days and 85.3% at one year. At the one-year follow-up, the all-cause mortality rate was 3.7% (1.5% cardiac deaths), the MI rate was 3.7%, and the incidence of definite or probable stent thrombosis (ST) was 2.9%. Female gender [hazard ratio (HR), 4.40; 95% confidence interval (CI), 1.81-10.66; p = 0.001) and non-right coronary artery PCI (HR, 3.49; 95%CI, 1.42-8.59; p = 0,006) were independent predictors of MACE at one year. Freedom from adverse events at one year was higher in patients with stable angina who underwent PCI (HR, 0.33; 95%CI, 0.13-0.80; p = 0.014). CONCLUSIONS: PCI using FMJ with DES for very long lesions was efficacious but associated with a high rate of ST at the one-year follow-up. However, the rate of cardiac mortality, nonprocedure-related MI, and MACE was relatively low. Target coronary vessel PCI, clinical presentation, and female gender are new contemporary clinical factors that appear to have adverse effects on the outcome of PCI using FMJ for long lesions.

ABSTRACT

Objetivo: Evaluar nuestros resultados a corto y largo plazo en la cirugía de bypass para el grupo de enfermedad coronaria multivasos (3 vasos y/o tronco izquierdo). Analizar recientes estudios que comparan stent liberador de drogas (DES del inglés Drug eluting stents) versus cirugía. Actualizar recomendaciones. Métodos: Se analiza retrospectivamente 121 pacientes consecutivos tratados con cirugía de revascularización miocárdica por enfermedad coronaria multivasos entre diciembre de 1998 y febrero de 2008 y se comparan con los resultados de la literatura. Además se evaluó la presencia de factores de riesgo preoperatorios que influenciarían los resultados. Resultados: La mortalidad hospitalaria (30 días) fue de 2.5%. A un seguimiento de 4.4 años, en 100 pacientes se observa una sobrevida de 93.21% y una necesidad de repetir revascularización de 3.3%. Conclusión: Se observa un aumento de los factores de riesgo (edad y procedimientos coronarios previos, sean quirúrgicos o intervencionistas) en la población que acude a cirugía, a pesar de lo cual la morbi-mortalidad continúa baja, incluso en el seguimiento a largo plazo. Nuestros resultados concuerdan con los de las publicaciones internacionales de centros avanzados. Estudios randomizados y observacionales de estos centros muestran, en la enfermedad coronaria multivasos, que la cirugía tiene menos eventos adversos cardiacos y cerebro vasculares que el stent y ventaja en la sobrevida a largo plazo. La cirugía se mantiene como la opción preferida para la enfermedad coronaria multivasos no aguda, en especial cuando las lesiones coronarias son anatómicamente complejas.


Objective: With this study we have assessed our early and late surgical outcomes in patients with Multivessel Coronary Artery Disease (CAD) (defined as 3 coronary vessels or Left Main Coronary Disease) treated with Coronary Artery Bypass Grafting (CABG) Surgery. We have analyzed studies comparing Drug Eluting Stent (DES) versus CABG Surgery to treat Multivessel CAD. We have reviewed all up to date guidelines and recommendations. Methods: We have retrospectively analyzed 121 consecutive patients with multivessel CAD treated with CABG surgery. Results: In-hospital mortality (30 days) was 2,5 %. A subsequent follow up of 100 patients after 4,4 years showed a rate of survival of 93.21 % and the need for repeat myocardial revascularization procedures in 3,3%. Conclusion: CABG surgery to treat Multivessel CAD has low morbidity and mortality even with increase in the risk factors of the population.We have similar results to other published Randomized Controlled and Observational Trials. These studies show that CABG surgery has lower rates of Mayor Adverse Cardiac and Cerebrovascular Events (MACCE) and higher survival rates than DES. Surgery is still the treatment of choice for non-acute multivessel CAD, especially when there is a complex anatomy.

ABSTRACT

Intra-aortic balloon pump (IABP) is an established tool in the management of cardiac dysfunction in cardiac surgery. The best timing for IABP weaning is unknown and varies greatly among cardiac centers. The authors investigated the differences in IABP management among 66 cardiac surgery centers performing 40,675 cardiac surgery procedures in the 12-month study period. The centers were contacted through email, telephone, or in person interview. IABP management was very heterogeneous in this survey: In 43% centers it was routinely removed on the first postoperative day, and in 34% on the second postoperative day. In 50% centers, it was routinely removed after extubation of the patients whereas in 15% centers it was removed while the patients were sedated and mechanically ventilated. In 66% centers, patients were routinely receiving pharmacological inotropic support at the time of removal of IABP. The practice of decreasing IABP support was also heterogeneous: 57% centers weaned by reducing the ratio of beat assistance whereas 34% centers weaned by reducing balloon volume. We conclude that the management of IABP is heterogeneous and there is a need for large prospective studies on the management of IABP in cardiac surgery.

ABSTRACT

Se presenta el caso de un paciente con antecedente de enfermedad coronaria y falla cardiaca severa, con trasplante cardiaco 17 años atrás, con diagnóstico de Sahos moderado a severo, considerado como de alto riesgo, que requiere manejo con dispositivo de presión positiva en vía aérea (CPAP), cuya adaptación y tolerancia no son adecuadas por la presencia de una desviación septal obstructiva. Luego de la valoración de riesgos y beneficios y después de una evaluación exhaustiva de su estado cardiovascular, se realiza una septo-turbinoplastia, que permite mejorar la adaptación y tolerancia del CPAP. Se plantean consideraciones anestésicas y quirúrgicas en este tipo de pacientes.


We report the case of a patient with a history of coronary artery disease and severe heart failure, heart transplant 17 years ago, diagnosed with moderate to severe OSAHS, considered as high risk, which requires management with positive pressure device in air (CPAP), whose adaptation and tolerance are not suitable because of the presence of obstructive septal deviation. After the assessment of risks and benefits and after a thorough assessment of your cardiovascular, performing a septo-turbinoplasty, which improves the adaptation and tolerance of CPAP. Arise anesthetic and surgical considerations in these patients.

ABSTRACT

Fundamentos: O controle dos fatores de risco cardiovascular em pacientes com doença arterial coronariana (DAC) é um grande desafio, principalmente nos pacientes mais graves nos quais as metas terapêuticas são mais rigorosas.Objetivo: Analisar a obtenção das metas terapêuticas e a prescrição das medicações nos pacientes portadores deDAC após revascularização miocárdica (CRM). Métodos: Analisados os prontuários de 68 pacientes submetidos à CRM, com pelo menos um ano deacompanhamento após a cirurgia. Pacientes submetidos à troca valvar associada foram excluídos da análise.Resultados: Quarenta e cinco (66,2%) pacientes eram do sexo masculino com média de idade de 60,3±9,1 anos. Aprincipal indicação para CRM foi angina instável (62%). Noventa e quatro por cento dos pacientes eram hipertensos, 28% diabéticos, 50% dislipidêmicos e 50% tinham história prévia de infarto agudo do miocárdio. A média da fração de ejeção foi 60±13%. A lesão do troncoda coronária esquerda ocorreu em 29% dos pacientes e o número médio de enxertos foi 2,7±0,75. Após um ano de pós-operatório, 73,0% dos pacientes usavam IECA, 86,6% betabloqueador, 83,0% AAS e 96,6% estatina. No pós-operatório, o controle dos fatores de risco foi obtido nas proporções: PAS<140mmHg (55,9%), PAD<90mmHg (62,7%), glicose<100mg% (41,1%), colesteroltotal<200mg% (70,9%),LDL<100mg% (57,7%) ou LDL<70mg% (28,8%), HDL>45mg% (32,0%) etriglicerídeos<150mg% (47,8%).Conclusão: Os pacientes após um ano de CRM apresentam índices de controle pressórico, glicêmico e lipídico inadequados. O uso das medicações para DAC foi considerado adequado, exceto para o uso de IECA que poderia ser mais utilizada.
