Dispositivos de asistencia ventricular como tratamiento de destino. A propósito de un caso.

The treatment of refractory terminal heart failure has been heart transplantation. However, there are limitations with regard to clinical conditions of the recipient and availability of donors, and ventricular support has therefore been alternatively used as destination therapy. We describe the case is of a female patient with ischemic cardiomyopathy-associated heart failure who had a left ventricular assist device successfully implanted and at eight months of the procedure was at functional class I, with no complications.

El tratamiento de la falla cardiaca terminal avanzada ha sido el trasplante de corazón, sin embargo, hay limitantes en cuanto a las características del receptor y disponibilidad de donadores, por lo que se ha utilizado alternativamente el soporte ventricular como tratamiento de destino. Se describe a una paciente con falla cardiaca terminal por cardiomiopatía isquémica en quien se implantó exitosamente un sistema de soporte ventricular izquierdo y a ocho meses del procedimiento se encontraba en clase funcional I, sin complicaciones.

[Retrasplante cardiaco electivo. Primer caso en México].

Orthotopic cardiac retransplantation is used to treat transplanted cardiac graft end-stage failure. We present the first case of successful elective cardiac retransplantation in Mexico. It was a 25-year old male with heart transplantation who developed graft-resistant chronic vasculopathy. He underwent elective retransplantation in September 2017; complications during postoperative evolution were treated with favorable response. He was discharged owing to improvement at four weeks postoperatively. It is concluded that in adequately selected cases and comprehensively assessed, cardiac retransplantation is an appropriate option to treat cardiac graft failure.

El retrasplante cardiaco ortotópico se utiliza para tratar la falla cardiaca terminal del injerto cardiaco trasplantado. Presentamos el primer caso exitoso de retrasplante cardiaco electivo en México. Se trató de un varón de 25 años con trasplante de corazón, quien presentó vasculopatía crónica resistente del injerto. Fue retrasplantado electivamente en septiembre de 2017; las complicaciones durante la evolución posoperatoria fueron tratadas con respuesta favorable. Egresó por mejoría a las cuatro semanas del posoperatorio. Se concluye que en los casos apropiadamente seleccionados y valorados integralmente, el retrasplante cardiaco es una opción adecuada para el manejo de la falla cardiaca del injerto.

[Heart transplantation for the treatment of isolated left ventricular myocardial noncompaction. First case in Mexico]. / Trasplante cardiaco: una opción para tratamiento del miocardio no compactado aislado de ventrículo izquierdo. Primer caso en México.

BACKGROUND: Myocardial noncompaction of the left ventricle is a congenital cardiomyopathy characterised by left ventricular hypertrabeculation and prominent intertrabecular recesses. The incidence ranges from 0.15% to 2.2%. Clinical manifestations include heart failure, arrhythmias, and stroke. Prognosis is fatal in most cases. Heart transplantation is a therapeutic option for this cardiomyopathy, and few had been made worldwide. CLINICAL CASE: The case is presented of a 20 year-old male with noncompacted myocardium of the left ventricle, who had clinical signs of heart failure. His functional class was IV on the New York Heart Association scale. He was successfully transplanted. Its survival to 15 months is optimal in class I New York Heart Association, and endomyocardial biopsies have been reported without evidence of acute rejection. CONCLUSION: It is concluded that heart transplantation modified the natural history and improved survival in patients with this congenital heart disease.

[Combined heart-kidney transplantation in Mexic]. / Trasplante combinado de corazón-riñón en México.

BACKGROUND: In our country, heart and kidney transplantation is a novel option for treatment of combined terminal heart and kidney failure. This program began in 2012 for selected patients with documented terminal heart failure and structural kidney damage with renal failure. Description of cases: Between January 1, 2012 and April 30, 2016, we made 92 orthotopic heart transplantations. In five of these cases the heart transplantation was combined with kidney transplantation. RESULTS: There were three male and two female patients with a mean age 25.6 ± 5.2 years (range, 17-29). The patients improved their renal function and the heart transplantation was successful with an improved quality of life. One patient died from abdominal sepsis. The other patients are doing well. CONCLUSION: The combined heart-kidney transplantation is a safe and efficient procedure for patients with structural kidney and heart damage as a cause of terminal failure.
