Retrasplante cardíaco: reporte de un caso / Cardiac re-transplantation: case report

RESUMEN: El Trasplante cardíaco es la mejor alternativa para la insuficiencia cardíaca terminal, logrando buenos resultados de sobrevida y calidad de vida a largo plazo. Una de las causas más importantes de morbimortalidad es la falla del injerto, la que puede ser secundaria, entre otros, a rechazo agudo y/o vasculopatía y su presencia requiere considerar todas las alternativas terapéuticas, dentro de las cuales está el retrasplante. Los resultados de sobrevida en retrasplante cardíaco son buenos. No obstante, los pacientes presentan los riesgos de una terapia inmunosupresora más intensa, así como el desarrollo recurrente de vasculopatía del injerto. Por lo que se considera una opción en pacientes cuidadosamente seleccionados, dado que la experiencia internacional demuestra que la sobrevida del retrasplante es menor que en el primer trasplante. Presentamos el caso de un paciente trasplantado a los 42 años, quien desarrolla una enfermedad vascular del injerto e insuficiencia cardíaca con capacidad funcional IV, por lo cual se decidió realizar un retrasplante cardíaco.

ABSTRACT: Cardiac transplantation is the best alternative for terminal heart failure, achieving good long-term survival and life quality. One of the most important causes of morbidity and mortality is graft failure, which may be secondary, among others, to acute rejection and / or vasculopathy and its presence requires the consideration of all therapeutic alternatives, re transplantation being one of them. The results of survival in cardiac retransplantation are good; however, they present the risks of a more intense immunosuppressive therapy as well as the recurrent development of graft vasculopathy. Therefore, it is considered an option in carefully selected patients given that international experience shows that the survival of retransplantation is lower than in primary cases. We present the case of a 42 year old transplanted patient , who developed graft vascular disease with progressive deterioration of his ventricular function leading to functional class IV. for which a cardiaccardiac retransplantation was performed.

Heart Retransplantation to Treat a Case of Refractory Cardiac Allograft Vasculopathy / 대한내과학회지

Cardiac allograft vasculopathy is one of the most important causes of poor long-term survival after heart transplantation. The condition tends to be diffuse, usually affecting the mid-to-distal portions of the coronary artery. Reperfusion therapy is ineffective. Everolimus, an inhibitor of proliferation signaling, has been reported to prevent development of the condition; however, the efficacy thereof has not yet been fully accepted. The only definitive treatment for cardiac allograft vasculopathy is retransplantation. Herein, we describe the case of a 15-year-old boy who underwent heart retransplantation because of rapidly progressive cardiac allograft vasculopathy.
