Anomalía de Ebstein y preeclampsia, asociación infrecuente: reporte de caso y revisión de la literatura / Ebstein's anomaly and preeclampsia, a rare association: case report and literature review

Resumen Se presenta el caso de una gestante con cardiopatía congénita no estudiada que acudió al servicio de urgencias en la semana 25 + 4 por palpitaciones, con evidencia de hipertensión arterial desde el ingreso. Los estudios diagnósticos revelaron anomalía de Ebstein, con gran compromiso de cavidades derechas y asociado a comunicación interauricular. También se documentó preeclampsia lejos del término, con restricción grave del crecimiento intrauterino. Durante la estancia hospitalaria, y ante negativa de la paciente a finalizar la gestación, desarrolló síntomas de congestión pulmonar por sobrecarga. Una vez falleció el feto in utero y después de inducir el parto, remitieron los síntomas cardiovasculares y se controló la hipertensión.

Abstract We present the case of a pregnant woman with previously undiagnosed congenital heart disease, who presented to the emergency department at week 25 + 4 due to palpitations, with evidence of arterial hypertension from admission. Diagnostic studies revealed Ebsteins anomaly, with great involvement of the right cavities and associated with atrial septal defect. Preeclampsia was also documented far from term, associated with severe intrauterine growth restriction. During the hospital stay and due to the refusal of the patient to end the pregnancy, she developed symptoms of pulmonary congestion due to overload, once the fetus died in utero and after inducing labor, the cardiovascular symptoms remitted and hypertension was controlled.

Anomalía de Ebstein y aneurisma del seno coronario / Ebstein’s anomaly and coronary sinus aneurysm

Resumen La anomalía de Ebstein es una cardiopatía congénita poco común que se asocia a la presencia de vías de conducción anómalas y episodios de taquicardia supraventricular frecuentes, algunos inestables. La asociación con alteraciones anatómicas del seno coronario es rara y no ha sido reportada. Se presenta el caso de una paciente de 58 años con enfermedad coronaria, anomalía de Ebstein, episodios de taquicardia ortodrómica y aneurisma del seno coronario, a quien se realizó ablación.

Abstract Ebstein’s disease is a congenital cardiomyopathy, with a low prevalence in the general population. This abnormality has been associated with abnormal cardiac conduction problems, one of the most important being the accessory pathways. In the presence of an accessory pathway, frequent supraventricular tachycardias may occur, some of which are poorly tolerated. The association with the anomalies of the coronary sinus is not currently reported. The case of a 58-year-old woman with Ebstein’s disease, episodes of supraventricular tachycardia, and coronary sinus aneurysm undergoing ablation therapy is presented.

Rare diagnostics of Ebstein anomaly in an adult patient in Northern Rio de Janeiro / Diagnóstico raro da anomalia de Ebstein no norte do Rio de Janeiro em um paciente adulto

Ebstein anomaly is the fourth most frequent cyanotic heart disease in the neonatal period, and its clinical course is slow compared to other diseases, which in turn results in late diagnosis of this condition. We present a case of a 37-year-old man who complained of palpitation for about 5 years, twice a week, at rest, with prolonged duration and low systemic output. Auscultation revealed irregular heart rhythm characterized by extrasystoles with a tricuspid systolic murmur grade 5+/6 and worsening on inspiration. Clinical spectrum is variable and depends on the severity of defects and associated anatomical changes. In patients who have reached adulthood, symptoms usually present as progressive cyanosis, exercise intolerance, right heart failure, and arrhythmias. In Brazil, identification of this congenital disease usually occurs in a more adult phase, affecting the prognosis and survival of patients. (AU)

Anomalia de Ebstein é a quarta cardiopatia cianótica com maior frequência no período neonatal, cuja evolução clínica é lenta em comparação com outros tipos de doenças, o que, por sua vez, resulta no diagnóstico tardio. Apresentamos o caso de um homem de 37 anos, com queixa de palpitações por cerca de cinco anos, duas vezes por semana, em repouso, com duração prolongada e com baixo débito sistêmico. A ausculta revelou ritmo cardíaco irregular por extra-sístoles com sopro sistólico na tricúspide, 5 + / 6 piora na inspiração. O espectro clínico é variável e ocorre de acordo com a gravidade dos defeitos e alterações anatômicas associadas. Pacientes que atingiram a idade adulta, os sintomas geralmente se apresentam como cianose progressiva, intolerância ao exercício, insuficiência cardíaca direita e arritmias. A realidade brasileira é que a identificação dessa doença congênita persiste em uma fase adulta, afetando o prognóstico e a sobrevida desses pacientes. (AU)

Válvula tricúspide displásica (Ebstein-like) / Tricuspid valve dysplasia (Ebstein-like)

Resumen La anomalía de Ebstein es una malformación caracterizada por el desplazamiento apical de las inserciones de las valvas septal y posterior de la válvula tricúspide, así como del anillo funcional tricúspide y por la atrialización del ventrículo derecho. Se han encontrado casos durante cirugías que no han cumplido con estos criterios, y que, por tanto, se han clasificado como "anomalías Ebstein-like". Algunos de ellos han sido descritos anatómicamente como válvulas displásicas. Se presenta el caso de una mujer de 20 años que presentó disnea clase III de la Asociación del Corazón de Nueva York y dolor punzante en el pecho, que se clasificó como una posible anomalía de Ebstein por ecocardiografía; sin embargo, los hallazgos intraoperatorios fueron compatibles con una válvula tricúspide displásica con dilatación del anillo funcional. Este caso destaca la importancia del uso adecuado de la ecocardiografía, así como la necesidad de estudios prospectivos sobre los casos de Ebstein-like.

Abstract The Ebstein anomaly is a malformation characterised by the apical displacement of the insertions of the septal valve and the posterior tricuspid valve, displaced tricuspid functional ring, and atrialisation of the right ventricle. Cases have been found during surgery that have complied with these criteria, and have therefore been classified as "Ebstein-like anomalies". Some of them have been described anatomically as valve dysplasia. The case is presented of a 20 year-old female that presented with dyspnoea Class III of the New York Heart Association, and a stabbing pain in the chest. This was classified as a possible Ebstein anomaly by cardiac ultrasound. However the findings during the surgery were compatible with tricuspid valve dysplasia with dilation of the functional ring. This case highlights the importance of the appropriate use of cardiac ultrasound, as well as the need to carry out prospective studies on Ebstein-like cases.

Caso clínico: adulto con anomalía de Ebstein / Clinical case: adult with Ebstein anomaly

Introducción: la anomalía de Ebstein se caracteriza por la implantación baja de las valvas septal y posterior de la tricúspide; por lo tanto, la aurícula derecha es amplia y su ventrículo es pequeño. Al ser una patología bastante rara en nuestro medio se encuentra subdiagnosticada y no recibe el tratamiento oportuno. Por ende, la importancia de conocerla para no retrasar su manejo clínico quirúrgico.Caso clínico: paciente de 46 años de edad, masculino, con antecedente de hipoacusia congénita, presentó disnea (clase funcional III) más palpitaciones y dolor torácico atípico hace 1 año aproximadamente. Al examen físico evidenció soplo holosistólico en foco tricuspídeo y uso moderado de musculatura accesoria. Al ecocardiograma transesofágico, se observó arritmia auricular más implante bajo de las valvas de la tricúspide y se inició tratamiento clínico más ablación del flutter. En la evolución presentó mejoría de la sintomatología y dependiendo del deterioro de la clase funcional, tratamiento quirúrgico Conclusiones: en el presente caso se ajustó tratamiento clínico y ablación del flutter de acuerdo a sintomatología del paciente, mostrando mejoría (AU);

Introduction: Ebstein's anomaly is characterized by low implantation of the septal and posterior tricuspid leaflets; therefore, the right atrium is wide and its ventricle is small. Being a rather rare pathology in our environment, it is underdiagnosed and does not receive the appropriate treatment. Therefore, it is important to know it to avoid a delay in its clinical surgical management.Clinical case: The patient is 46-year-old male, with a history of congenital hearing loss, who presented dyspnea (functional class III) plus palpitations and atypical chest pain approximately 1 year ago. In the physical examination, he revealed a holosystolic murmur in the tricuspid focus and moderate use of accessory muscles. A transesophageal echocardiogram revealed atrial arrhythmia plus implantation of the tricuspid leaflets and it was started a clinical treatment plus flutter ablation. In the evolution he presented improvement of the symptoms and depending on the deterioration of the functional class, surgical treatment.Conclusions: in this case, clinical treatment and flutter ablation were adjusted according to the patient's symptoms, showing improvement (AU);

Consideraciones útiles para el asesoramiento genético de pacientes con anomalía de Ebstein / Useful considerations for the genetic advice of patients with Ebstein anomaly

La anomalía de Ebstein es una rara enfermedad que consiste en un espectro variable de anomalías, resultado de una implantación anormal de la válvula tricúspide en el ventrículo derecho; por tal razón, es considerada una afección grave e incurable que origina una tendencia a la terminación voluntaria del embarazo como opción reproductiva en el marco del asesoramiento genético prenatal. Los adelantos en el diagnóstico y control clinicoquirúrgico de esta enfermedad han garantizado el incremento de la supervivencia y una mejor calidad de vida en estos pacientes. Además, han permitido ajustar factores clínicos que implican su evolución y pronóstico. Se realizan algunas valoraciones, a fin de proveer los argumentos necesarios que permitan a la pareja elegir un curso de acción apropiado con vistas a los riesgos y objetivos familiares basados en los principios éticos del asesoramiento genético.

Ebstein anomaly is a strange disease that consists on a variable spectrum of anomalies, due to an abnormal installation of the tricuspid valve in the right ventricle; reason why, it is considered a serious and incurable disorder that originates a tendency to the voluntary termination of pregnancy as reproductive option in the mark of prenatal genetic advice. The advances in the diagnosis and clinical surgical control of this disease have guaranteed the increment of survival and a better life quality in these patients. Also, they have allowed to adjust clinical factors that involve its clinical course and prognosis. Some valuations are carried out, in order to provide the necessary arguments that allow the couple to choose an appropriate action course aimed at the risks and family objectives based on the ethical principles of the genetic advice.

Early and long-term outcomes of surgical treatment of ebstein's anomaly

Abstract Objective: This study aimed to evaluate Ebstein's anomaly surgical correction and its early and long-term outcomes. Methods: A retrospective analysis of 62 consecutive patients who underwent surgical repair of Ebstein's anomaly in our institution from January 2000 to July 2016. The following long-term outcomes were evaluated: survival, reoperations, tricuspid regurgitation, and postoperative right ventricular dysfunction. Results: Valve repair was performed in 46 (74.2%) patients - 12 of them using the Da Silva cone reconstruction; tricuspid valve replacement was performed in 11 (17.7%) patients; univentricular palliation in one (1.6%) patient; and the one and a half ventricle repair in four (6.5%) patients. The patients' mean age at the time of surgery was 20.5±14.9 years, and 46.8% of them were male. The mean follow-up time was 8.8±6 years. The 30-day mortality rate was 8.06% and the one and 10-year survival rates were 91.9% both. Eleven (17.7%) of the 62 patients required late reoperation due to tricuspid regurgitation, in an average time of 7.1±4.9 years after the first procedure. Conclusion: In our experience, the long-term results of the surgical treatment of Ebstein's anomaly demonstrate an acceptable survival rate and a low incidence of reinterventions.

Anesthetic management for patient with severe cyanosis following bioprosthetic valve stenosis / Manejo anestésico de paciente com cianose grave após estenose de valva bioprotética

Abstract We presented a 39-year-old female patient with life-threatening hypoxemia after tricuspid valve replacement because of Ebstein's anomaly. And the severe cyanosis is due to bioprosthetic valve stenosis and atrial septal defect. Anesthetic management of a patient with severe obstructive prosthetic valve dysfunction can be challenging. Similar considerations should be given to patients with Ebstein's anomaly to maintain the pressure equalized between the right and left atrial. Transesophageal echocardiography and cerebral oxygen saturation provided real time information in perioperative care.

Resumo Apresentamos o caso de uma paciente de 39 anos, com hipoxemia em risco de vida após a substituição da valva tricúspide devido à anomalia de Ebstein e cianose grave devido à estenose de valva bioprotética e comunicação interatrial. O manejo anestésico de um paciente com disfunção obstrutiva grave de prótese valvar pode ser um desafio. Os pacientes com anomalia de Ebstein também precisam de atenção especial para manter a pressão equalizada entre o átrio direito e o esquerdo. A ecocardiografia transesofágica e a saturação cerebral de oxigênio forneceram informações em tempo real nos cuidados perioperatórios.

Ebstein's anomaly: "The one and a half ventricle heart"

Abstract Objective: Ebstein's anomaly remains a relatively ignored disease. Lying in the 'No Man's land' between congenital and valve surgeons, it largely remains inadequately studied. We report our short-term results of treating it as a 'one and a half ventricle heart' and propose that the true tricuspid annulus (TTA) 'Z' score be used as an objective criterion for estimation of 'functional' right ventricle (RV). Methods: 22 consecutive patients undergoing surgery for Ebstein's anomaly were studied. Echocardiography was performed to assess the type and severity of the disease, tricuspid annular dimension and its 'Z' score. Patients were operated by a modification of the cone repair, with addition of annuloplasty, bidirectional cavopulmonary shunt (BCPS) and right reduction atrioplasty to provide a comprehensive repair. TTA 'Z' score was correlated later with postplication indexed residual RV volume. Results: There was one (4.5%) early and no late postoperative death. There was a significant reduction in tricuspid regurgitation grading (3.40±0.65 to 1.22±0.42, P<0.001). Residual RV volume reduced to 71.96±3.8% of the expected volume and there was a significant negative correlation (rho −0.83) between TTA 'Z' score and indexed residual RV volume. During the follow-up of 20.54±7.62 months, the functional class improved from 2.59±0.7 to 1.34±0.52 (P<0.001). Conclusion: In Ebstein's anomaly, a higher TTA 'Z' score correlates with a lower postplication indexed residual RV volume. Hence, a complete trileaflet repair with offloading of RV by BCPS (when the TTA 'Z' score is >2) is recommended. The short-term outcomes of our technique are promising.

Reversão de taquicardiomiopatia de coração nativo em paciente com transplante cardíaco heterotópico / Reversion of native heart tachycardiomyopathy in a patient with heterotopic cardiac transplantation

Relatamos o caso de paciente portadora de anomalia de Ebstein, submetida a transplante cardíaco heterotópico após insucesso na correção cirúrgica. Apesar da melhora clínica inicial, a paciente permanecia dispneica em decorrência de dissincronia sistólica entre os corações gerada por flutter atrial do coração nativo. Após a cardioversão desse flutter, o eletrocardiograma já apresentava espontaneamente o sincronismo sistólico entre ambos os corações. Houve significativa melhora tanto clínica como ecocardiográfica do coração nativo. A redução da frequência cardíaca do coração nativo após reversão do flutter colaborou para a melhora de seu desempenho hemodinâmico, caracterizando ser essa disfunção secundária à taquicardia.

We report the case of a patient with Ebstein Anomaly, submitted to heterotopic cardiac transplantation after a failed surgical correction. Despite the initial clinical improvement, the patient remained dyspneic due to systolic dyssynchronism between the hearts, generated by atrial flutter of the native heart. After flutter cardioversion, the electrocardiogram already presented systolic synchronism between both hearts. There was a significant clinical and echocardiographic improvement of the native heart. The heart rate reduction of the native heart after flutter reversal led to hemodynamic improvements, characterizing it as being secondary to tachycardia

Outcomes of Ebstein's Anomaly Patients Treated with Tricuspid Valvuloplasty or Tricuspid Valve Replacement: Experience of a Single Center / 中华医学杂志(英文版)

<p><b>Background</b>The incidence of Ebstein's anomaly is extremely low, and except for the Mayo Clinic, no cardiac center has reported on a sufficient number of patients. The aim of our study was to report the outcomes of Ebstein's anomaly patients treated with tricuspid valvuloplasty (TVP) or tricuspid valve replacement (TVR).</p><p><b>Methods</b>TVP or TVR was performed in 245 patients from July 2006 to April 2016. We reviewed patients' records and contacted patients via outpatient service and over the telephone.</p><p><b>Results</b>The mean follow-up time was 43.6 ± 32.6 months, and 224 (91.4%) patients underwent follow-up. The mean operative age was 31.2 ± 15.7 years. TVR was performed in 23 patients, and TVP was performed in 201 patients. The 30-day mortality rate was 1.3%, and the overall survival rate was 97.9% at 5 and 10 years. The early mortality rate of the TVP group was lower than that of the TVR group (0.5% vs. 8.7%, P = 0.028), and the overall mortality rate of the TVP group was lower than that of the TVR group, without statistical significance (1.0% vs. 8.7%). After propensity score matching, the rates of mortality and New York Heart Association class ≥ III were lower in the TVP group than those in the TVR group without statistical significance. Seven patients with Type B Wolff-Parkinson-White (WPW) syndrome underwent one-stage surgery, and arrhythmias disappeared. Six patients suffered from episodes of left ventricular outflow tract obstruction (LVOTO) during surgery. Severe LVOTO could be treated with reoperation of the atrialized right ventricle.</p><p><b>Conclusions</b>Ebstein's anomaly patients treated with TVP or TVR can experience optimal outcomes with midterm follow-up. However, TVP should be the first-choice treatment. Optimal outcomes can be obtained from one-stage operation in patients with Type B WPW syndrome. Severe LVOTO during surgery might be related to improper operation of the atrialized right ventricle.</p>

Consideraciones anestésicas en la anomalía de Ebstein / Anesthetic considerations in Ebstein's anomaly

Introducción: la anomalía de Ebstein es una rara malformación congénita cardiaca, definida por un desplazamiento apical de las valvas septal y posterior de la válvula tricúspide hacia el interior del ventrículo derecho, en vez de hacerlo a nivel del anillo auriculoventricular, lo cual conlleva un aumento del volumen de la aurícula derecha (megaurícula) a expensas de una reducción del tamaño del ventrículo del mismo lado (auriculización del ventrículo). Causa una significante regurgitación tricuspídea y reducción de la capacidad funcional del ventrículo, dilatación atrioventricular derecha, con arritmias auriculares y ventriculares, las que tienden a hacerse resistentes en ocasiones, o de difícil tratamiento. El desplazamiento del orificio valvular tricuspídeo produce una división del ventrículo derecho en una porción integrada al atrio derecho, lo que constituye la porción atrializada del ventrículo derecho, en tanto la porción apicotrabecular y de salida constituye su parte funcional. Objetivo: presentar la evolución clínico-anestesiológica de una paciente con anomalía de Ebstein. Caso clínico: paciente de 69 años de edad programada para cirugía electiva en dos ocasiones por diferentes enfermedades oncológicas, portadora de anomalía de Ebstein. Antecedentes de tromboembolismo pulmonar, tres cirugías cardiacas, diabetes mellitus e hipertensión arterial, enfermedad arterial aterosclerótica estable e infarto cerebral media derecha embólico. Se evitaron aquellas condiciones que aumenten el trabajo cardiaco y el consumo de oxígeno. Conclusiones: el desafío que representa para el anestesiólogo, aquellos pacientes que sufren anomalía de Ebstein puede variar de paciente a paciente, en dependencia del estado físico, el tipo de enfermedad y las técnicas de monitorización(AU)

Introduction: Ebstein's anomaly is a rare congenital cardiac malformation, defined by an apical displacement of the septal and posterior leaflets of the tricuspid valve into the right ventricle, instead of at the level of the atrioventricular ring, which leads to an increase of the volume of the right atrium (mega atrium) at the expense of a size reduction for the ventricle on the same side (auriculization of the ventricle). It causes a significant tricuspid regurgitation and reduction of the functional capacity of the ventricle, right atrioventricular dilation, with atrial and ventricular arrhythmias, which tend to become resistant at times, or difficult to treat. The displacement of the tricuspid valve orifice produces a division of the right ventricle in a portion integrated to the right atrium, which constitutes the atrialized portion of the right ventricle, while the apico-trabecular and exit portion constitutes its functional part. Objective: To present the clinical-anesthesiological evolution of a patient with Ebstein's anomaly. Clinical case: A 69-year-old patient, with Ebstein's anomaly, who was scheduled for elective surgery on two occasions for different oncological diseases. History of pulmonary thromboembolism, three cardiac surgeries, diabetes mellitus and arterial hypertension, stable atherosclerotic arterial disease, and right middle cerebral infarction. Conditions that increase cardiac work and oxygen consumption were avoided. Conclusions: The challenge patients suffering from Ebstein's anomaly represent for the anesthesiologist can vary from patient to patient, depending on the physical state, the type of disease, and the monitoring techniques(AU)
