RESUMO

A 61-year-old male who lived for 30 years in a rural area presented chest pain of 3 months duration. Multiple hydatid cysts (Echinococcus granulosus) were diagnosed in the pericardium and the mediastinum by echocardiography and computed tomography. The cysts were removed successfully with the patient on cardiopulmonary bypass and beating heart.  This video tutorial shows how we removed the cysts, using the puncture-aspiration and enucleation technique.  Few videos of this technique exist, and we believe that this tutorial is a helpful demonstration of how to handle mediastinal and pericardial hydatid cysts.

RESUMO

Injury of the circumflex artery (Cx) during mitral valve surgery is a rare and underrecognized life-threatening complication. A retrospective analysis of patients undergoing mitral valve operations at 2 centers was conducted. Five mitral valve operations are described. After diagnosis of Cx injury, 2 patients were treated by stent implantation, 1 by coronary bypass to the Cx, and 1 by repositioning the responsible annular stitches. In another patient, the Cx injury was not treated and was diagnosed at autopsy. There were no deaths in patients whose Cx injury was promptly treated. Cx injury can be successfully managed when it is treated on time.

RESUMO

Resumen: Existe en la actualidad controversia acerca del mejor tratamiento para los pacientes portadores de trombosis valvular protésica. Muchos factores deben ser tenidos en cuenta al momento de decidir entre la resolución quirúrgica o el tratamiento con fibrinolíticos sistémicos. Las guías americanas recomiendan en plano de igualdad ambas terapéuticas, poniendo énfasis en el análisis de cada caso en particular. Las guías europeas, en cambio, le dan mayor nivel de recomendación a la cirugía, dejando la fibrinólisis para aquellos pacientes con alto riesgo quirúrgico. Se presenta el caso de una paciente de 54 años, portadora de prótesis mitral mecánica implantada hace 15 años, disfuncionante, en clase funcional II de la New York Heart Association, y se discuten las opciones diagnósticas y terapéuticas.


Summary: There is ongoing debate regarding the optimal treatment for patients with prosthetic valve thrombosis. Several issues must be taken into consideration before defining either surgical or fibrinolytic treatment. North American guidelines place both therapeutic modalities under the same recommendation grade with special emphasis on the analysis of each individual case. European guidelines place surgical treatment as the preferred option except in patients with high surgical risk. Thereby, we present the clinical case of a 54 year old female with dysfunctional mechanical mitral prosthesis implanted 15 years ago and functional class II of the New York Heart Association. Diagnostic and therapeutic approaches are discussed.

RESUMO

RESUMEN: Introducción: La cirugía convencional para la enfermedad valvular aórtica continúa siendo el estándar de oro con resultados muy adecuados con relación al riesgo preoperatorio que presenta. El uso de las válvulas transcatéter para el tratamiento de la estenosis aórtica (EAO) ha crecido exponencialmente y se postula para pacientes de riesgo intermedio (RI). En nuestro medio es infrecuente el hallazgo de resultados de la cirugía en este grupo en particular, por lo que presentamos la casuística en nuestro "mundo real". Objetivos: Complicaciones tempranas en pacientes sometidos a reemplazo valvular aórtico (RVA) con RI preoperatorio de mortalidad (STS PROM% 4%-8%). Material y métodos: Análisis retrospectivo de pacientes sometidos a RVA desde enero de 2007 hasta marzo de 2017. Se realizaron 877 RVA aislados o asociados a cirugía de revascularización miocárdica (CRM). Fueron incluidospacientes con EAO grave, insuficiencia aórtica grave, endocarditis y con STS PROM de 4% a 8%. Fueron excluidos los pacientes de bajo y alto riesgo (STS PROM% < 4% o > 8%), cirugía valvular doble, o cirugías asociadas excepto CRM o ampliación del anillo aórtico. Resultados: Fue incluido un total de 97 pacientes. La edad media fue de 79,4 ± 6,18, y 60,82% de sexo masculino. La mediana de STS PROM% fue de 5,1 (4,4-6). En el 62,9% se realizó CRM. No se registraron casos de fuga paravalvular moderado-grave. La mortalidad a los 30 días fuede 5,1%. Las complicaciones fueron 3,1% de ACV isquémico, 4,1% requerimiento de MCP definitivo y 4,1% por reexploración por sangrado. La estadía hospitalaria total fue de 8 días (6-14). Conclusiones: Los pacientes de RI presentaron resultados acordes con los esperados en términos de morbimortalidad posoperatoria.

RESUMO

A 78-year-old man with a Kommerell diverticulum and aberrant right subclavian artery was admitted for thoracic pain and severe malnutrition due to esophageal compression. We performed an atypical surgical procedure including extra-anatomical debranching and direct aortic repair, trying to avoid deep hypothermic circulatory arrest and shorten the cardiopulmonary bypass time.

RESUMO

OBJECTIVES: Since its development in the late 1990s, the European System for Cardiac Operative Risk Evaluation (EuroSCORE) has been the predictive model of choice for estimating mortality after cardiac surgery. As outcomes from cardiac surgery improved, the EuroSCORE showed a loss of calibration, and a revised version of the model was developed, EuroSCORE II. The objectives of this study were to examine the validity of both scores in the Spanish population, and to depict the performance of both models on a funnel plot. METHODS: A prospective multicentre study was performed, with requests to participate sent to all centres in Spain. Participating centres reported the EuroSCORE, EuroSCORE II and the actual mortality of each patient. Incomplete data were requested to get a zero incidence of lost data. Calibration of models was evaluated with the Hosmer-Lemeshow goodness-of-fit test, and discrimination with the areas under the receiver operating characteristic (ROC) curve. A funnel plot was constructed using mortality data from the 2010 European Registry, to represent risk-adjusted mortality. RESULTS: Twenty Spanish centres participated in the study; 4034 patients undergoing cardiac surgery between 1 October 2012 and 31 March 2013 were collected. Prevalence of risk factors was analysed. The observed mortality rate was 6.5%. The mean additive EuroSCORE was 6.5. The mean expected mortality rate was 9.8% for the logistic EuroSCORE, and 5.7% for EuroSCORE II. Areas under the ROC curves were EuroSCORE: 0.77 [95% confidence interval (CI): 0.75-0.80], EuroSCORE II: 0.79 (95% CI: 0.76-0.82). Results for the goodness-of-fit test were EuroSCORE: 33.02 (P < 0.001), EuroSCORE II: 38.98 (P < 0.001). Risk-adjusted mortality is far beyond the lower bound of the CI if EuroSCORE is used as the reference model, and is between the confidence limits, but near to the upper bound when EuroSCORE II is used. CONCLUSIONS: Spanish cardiac surgical patients have a high-risk profile. Areas under the ROC curve show good discrimination for both models. Predicted mortality using EuroSCORE II more closely matches actual mortality than that predicted by the original EuroSCORE. Both models show statistically significant differences from the actual mortality rate, with EuroSCORE overpredicting and EuroSCORE II underpredicting mortality. The funnel plot illustrates risk-adjusted mortality clearly out of boundaries when EuroSCORE is used, and near underprediction when the reference is EuroSCORE II.

RESUMO

BACKGROUND: Animal study results point to oxidative stress as a key mechanism triggering postoperative atrial fibrillation (PoAF), yet the extent to which specific biomarkers of oxidative stress might relate to PoAF risk in humans remains speculative. METHODS AND RESULTS: We assessed the association of validated, fatty acid-derived oxidative stress biomarkers (F2-isoprostanes, isofurans, and F3-isoprostanes) in plasma and urine, with incident PoAF among 551 cardiac surgery patients. Biomarkers were measured at enrollment, the end of surgery, and postoperative day 2. PoAF lasting ≥30 seconds was confirmed with rhythm strip or electrocardiography and centrally adjudicated. Outcomes were assessed until hospital discharge or postoperative day 10, whichever occurred first. Urine level of each oxidative stress biomarker rose at the end of surgery (2- to 3-fold over baseline, P<0.001) and subsequently declined to concentrations comparable to baseline by postoperative day 2. In contrast, plasma concentrations remained relatively stable throughout the perioperative course. Urine F2-isoprostanes and isofurans at the end of surgery were 20% and 50% higher in subjects who developed PoAF (P≤0.009). While baseline biomarker levels did not associate significantly with PoAF, end of surgery and postoperative day 2 isoprostanes and isofurans demonstrated relatively linear associations with PoAF. For example, the end of surgery extreme quartile multivariate adjusted OR (95% CI) for urine isofurans and F3-isoprostanes were 1.95 (1.05 to 3.62; P for trend=0.01) and 2.10 (1.04 to 2.25, P for trend=0.04), respectively. The associations of biomarkers with PoAF varied little by demographics, surgery type, and medication use (P≥0.29 for each). CONCLUSIONS: These novel results add to accumulating evidence supporting the likely key pathogenic role of elevated oxidative stress in PoAF.

RESUMO

El trasplante cardíaco está indicado en pacientes con insuficiencia cardíaca terminal sin opción de tratamiento médico, intervencionista o quirúrgico y puede realizarse utilizando fundamentalmente tres variantes técnicas. El beneficio de la técnica bicava en términos de parámetros hemodinámicos y clínicos la ha convertido en la más utilizada, aunque es técnicamente más demandante y puede tener algunas consecuencias, como estenosis en las anastomosis de las venas cavas. En esta presentación se describe el caso de un paciente sometido a trasplante cardíaco ortotópico con técnica bicava que en el primer día del posoperatorio desarrolló el síndrome de la vena cava superior. Durante el segundo día posoperatorio y ante sintomatología progresiva, a pesar de haberse administrado anticoagulación, se decidió realizar una flebografía diagnóstica y al mismo tiempo tratamiento endovascular. En ese procedimiento se recanalizó la vena cava superior y se implantaron tres stents autoexpandibles, con lo que se logró permeabilidad de la anastomosis entre las venas cavas donante y receptora, la vena cava superior y la subclavia derecha. La evolución fue favorable con alivio inmediato de la sintomatología. El paciente fue dado de alta sin complicaciones.


Heart transplantation is indicated in patients with end-stage heart failure who have no options with medical, interventional or surgical treatment. Among the three techniques available, the bicaval technique is the one most frequently used due to its hemodynamic and clinical benefits. However, it is technically more demanding and may have some consequences, as vena caval anastomotic stenosis. We describe the case of a patient who developed superior vena cava syndrome at postoperative day one of orthotopic heart transplantation with bicaval technique. At the second day symptoms progressed and, despite having initiated anticoagulation therapy, the patient underwent a diagnostic phlebography followed by endovascular treatment. After dilatation of the superior vena cava three self-expandable stents were implanted producing patent anastomosis between the donor and receptor venae cavae, the superior vena cava and the right subclavian vena. The patient had favorable outcomes with immediate symptoms relief and was discharged without complications.

RESUMO

La sarcoidosis cardíaca es una enfermedad granulomatosa multisistémica de causa desconocida. El compromiso aislado del corazón es poco frecuente y el pronóstico se correlaciona con el grado de afectación de este órgano. El tratamiento inmunosupresor y el trasplante cardíaco han demostrado que prolongan la sobrevida; no obstante, existen comunicaciones de recidiva de la enfermedad en el órgano implantado. En esta presentación se describe un caso de recidiva de sarcoidosis cardíaca en un paciente con miocardiopatía dilatada con insuficiencia cardíaca avanzada, sometido a un trasplante cardíaco y en quien el diagnóstico de sarcoidosis cardíaca se estableció por el estudio anatomopatológico del corazón explantado. La evolución clínica fue favorable a pesar de la recidiva de la sarcoidosis en el órgano implantado.


Cardiac sarcoidosis is a multisystemic granulomatous disease of unknown etiology. Isolated cardiac involvement is rare and the prognosis correlates with the extension of heart compromise. Immunosupressive treatment and heart transplantation have demonstrated to improve survival; however, the presence of recurrences in heart transplant recipients has been reported. We describe a recurrence of cardiac sarcoidosis in a patient with advanced dilated cardiomyopathy who underwent heart transplantation. The diagnosis of sarcoidosis was made by histopathological study of the explanted heart. The patient had a favorable clinical course despite the recurrence of sarcoidosis in the transplanted heart.

RESUMO

La amiloidosis es una enfermedad infiltrativa sistémica que compromete al corazón y representa una causa importante de miocardiopatía restrictiva. Se describe el caso de un paciente masculino de 35 años con insuficiencia cardíaca avanzada secundaria a miocardiopatía infiltrativa por depósito amiloide. Durante su evaluación se realizó diagnóstico de neoplasia de células plasmáticas. Debido a la rápida progresión de los síntomas, el deterioro de la función ventricular y la incapacidad para tolerar el tratamiento adecuado para su enfermedad hematológica, se realizó trasplante cardíaco seguido de trasplante autólogo de médula ósea sin complicaciones. La presentación de este caso constituye la primera comunicación en nuestro país de trasplante cardíaco seguido de trasplante de médula ósea como tratamiento de la amiloidosis cardíaca.


Primary amyloidosis is a systemic infiltrative disease that compromises the heart and represents an important cause of restrictive cardiomyopathy. We describe a 35-year old man with advanced heart failure secondary to an infiltrative cardiomyopathy with amyloid deposition. A plasma cell neoplasm was also diagnosed. The patient evolved with rapid progression of symptoms and deterioration of ventricular function, and did not tolerate the adequate therapy due to the hematological disease. For this reason, he underwent heart transplantation followed by autologous bone marrow transplantation; no complications were reported. This is the first case of heart transplantation followed by bone marrow transplantation reported in our country for the treatment of cardiac amyloidosis.
