Introducción: El trasplante cardíaco continúa siendo el tratamiento de elección en pacientes con miocardiopatías graves sin otras opciones terapéuticas. Los resultados alentadores del trasplante cardíaco en términos de supervivencia han permitido ampliar los criterios de selección del receptor, lo que ha llevado a la inclusión de pacientes de mayor complejidad en lista de espera. Objetivo: Analizar los resultados del trasplante cardíaco del Hospital Universitario Fundación Favaloro a lo largo de 21 años de seguimiento. Material y métodos: Entre febrero de 1993 y diciembre de 2014 se realizaron 442 trasplantes cardíacos ortotópicos en un único centro. Se analizaron en forma retrospectiva las historias clínicas de los pacientes, excluyéndose los pediátricos y protegiendo la confidencialidad de los datos. Para el análisis se dividió la serie en período 1 (febrero 1993 - agosto 2003) y período 2 (septiembre 2003 - diciembre 2014). Resultados: Se observó durante el segundo período una prevalencia mayor de candidatos con miocardiopatía dilatada no coronaria versus coronaria y un incremento significativo de la indicación de trasplante cardíaco en la miocardiopatía dilatada chagásica. La prevalencia de hipertensión pulmonar aumentó, realizándose un número mayor de trasplantes cardíacos en condición de emergencia, con requerimiento de inotrópicos y soporte circulatorio mecánico con balón de contrapulsación intraaórtico. Conclusiones: Se han observado cambios en el perfil clínico de los receptores de trasplante cardíaco, ingresando en lista de espera pacientes con un número mayor de comorbilidades. La cuidadosa elección de candidatos a trasplante requiere una revisión continua y un análisis individualizado de los diferentes factores que determinan la supervivencia de los pacientes y su impacto en los resultados de los programas de trasplante. Background: Heart transplantation is still the treatment of choice in patients with severe cardiomyopathies that do not have any therapeutic options. The promising results of heart transplantation in terms of survival have modified the criteria of recipients’ selection, including more complex patients on the waiting list. Objective: The aim of this report is to analyze the outcomes of heart transplantation performed at the Hospital Universitario Fundación Favaloro after 21 years of follow-up. Methods: Between February 1993 and December 2014, 442 orthotopic heart transplantations were performed at a single center. The clinical records of the recipients, excluding pediatric patients, were retrospectively analyzed, ensuring the confidentiality of the information. Two periods were considered: period 1 (from February 1993 to August 2003) and period 2 (from September 2003 to December 2014). Results: During the second period, the prevalence of recipients with non ischemic versus ischemic dilated cardiomyopathy was higher, and the indication of heart transplantation in Chagas dilated cardiomyopathy showed a significant increase. The prevalence of pulmonary hypertension increased and more emergency heart transplantations were performed, with requirements of inotropic agents and mechanical circulatory support with intraaortic balloon pump. Conclusions: The clinical profile of heart transplantation recipients has changed and more patients on the waiting list have a greater number of comorbidities. The careful selection of candidates for transplantation needs continuous revision and an individual analysis of the different factors that determine patients’ survival and its impact on the outcomes of transplantation programs.

Heart transplantation (HTx) is the treatment of choice for advanced heart failure refractory to other treatments. Objective. To report the outcomes of patients undergoing orthotopic HTx in a center with 16 years' experience. Methods. We retrospectively examined the outcomes from three hundred nine HTx recipients between February 1993 and March 2009. The mean recipient age was 46 ± 16 years, and 80% were male. Ischemic cardiomyopathy was present in 37%; 43% (n = 133) were elective procedures and 57% (n = 176) were urgent/emergency procedures. The mean donor age was 26 years; their main cause of death was head/brain trauma. Survival was studied using Kaplan-Meier curves. Results. The global survival rates at 1, 5, 10, and 15 years were 80%, 74%, 71%, and 65%, respectively. Excluding losses during the first year after transplantation (conditional survival), the survival rate at 5 and 10 years reached 92% and 88.5%, respectively. The median follow-up was 7.7 years. The etiology and the urgent/emergency nature of the procedures did not show significant differences regarding the mortality rate (P = .8). The main causes of death were sepsis (28%) and primary nonfunction (18%). In-hospital mortality reached 16%. No significant differences were observed between the urgent/ emergency versus the elective transplant procedures (P = .06). During the follow-up, the incidence of severe acute cellular rejection episodes was
