- Heart Transplantation in Pediatric Population and in Adults With Congenital Heart Disease: Long-term Follow-up, Critical Clinical Analysis, and Perspective for the Future(2014) AZEKA, E.; JATENE, M.; GALAS, F. R. B.; TANAMATI, C.; PENHA, J.; BENVENUTI, L.; MIURA, N.; JUNIOR, J. O. C.Background. Heart transplantation is a treatment option for children as well as for adults with congenital heart disease. Objective. To report the experience of a tertiary center with heart transplant program in pediatric population and in adults with congenital heart disease. Patients and Methods. The study consisted of the evaluation of pediatric as well as adult patients undergoing heart transplantation for congenital heart disease. We evaluated the following indication and complications such as renal dialysis, graft vascular disease, tumors and survival. Results. From October 1992 to November 2013, 134 patients had transplantation, and there were 139 transplantations and 5 retransplantations. The immunosuppression regimen is based on calcineurin inhibitors and cytostatic drugs. The type of heart disease indicated for transplantation was cardiomyopathies in 70% and congenital heart disease in 30%. Of these 134 patients, 85 patients were alive. Actuarial survival is 77.4%, 69.6%, 59.3% at 1, 5, and 10 years after transplantation. Three patients underwent renal transplantation, 1 patient is in renal dialysis, and 8.2% of patients had post-transplant lymphoproliferative disease. Two patients had retransplantation for graft vascular disease; 1 of them required a simultaneous kidney transplant and died 30 days after the procedure and 1 patient is clinically well 2 years after retransplantation. Conclusion. Heart transplantation in children and in adults with congenital heart disease is a promising therapeutic option and enables long-term survival for these patients.

- Mechanical Circulatory Assistance in Children: Clinical Outcome(2023) CORBI, Maria Julia De Aro Braz; JATENE, Marcelo Biscegli; SIQUEIRA, Adailson Wagner Da Silva; GRAU, Claudia Regina Pinheiro Castro; TAVARES, Glaucia Maria Penha; IKARI, Nana Miura; AZEKA, EstelaBackground. In countries where organ donation is scarce, mortality in the pediatric heart transplant waiting list is high, and ventricular assist devices (VADs) are therapeutic alternatives in these situations. Berlin Heart EXCOR is currently 1 of the few VADs specific for children.Methods. This retrospective study includes pediatric patients who underwent Berlin Heart EXCOR placement in a Brazilian hospital between 2012 and 2021. Clinical and laboratory data at the time of VAD implantation and the occurrence of complications and outcomes (success as a bridge to transplant or death) were analyzed.Results. Eight patients, from 8 months to 15 years, were included: 6 with cardiomyopathy and 2 with congenital heart disease. Six were on Intermacs 1 and 2 on Intermacs 2. The most common complications observed were stroke and right ventricular dysfunction. Six were transplanted, and 2 died. Those submitted to transplant had a higher mean weight than those who died, with no statistically significant difference. The underlying disease had no impact on the outcome. The group undergoing transplant had lower brain natriuretic peptide and lactate values, but no laboratory variable showed a statistically significant difference in the outcome. Conclusion. A VAD is an invasive treatment with potentially serious adverse effects and is still poorly available in Brazil. However, as a bridge to transplant, it is a useful treatment for children in progressive clinical decline. In this study, we did not observe any clinical or laboratory factor at the time of VAD implantation that implied better outcomes.
- Heart Transplantation in Children and Adults With Congenital Heart Disease: 3 Decades of Evolution(2023) AZEKA, Estela; SIQUEIRA, Adailson Wagner Da Silva; TANAKA, Ana Cristina; MASSOTI, Maria Raquel Brigoni; MIANA, Leonardo; ZORZANELLI, Leina; GUIMARAES, Vanessa; PENHA, Juliano; CANEO, Luiz Fernando; TANAMATI, Carla; MIURA, Nana; JATENE, Marcelo BiscegliHeart transplantation is the treatment of choice for children and adults with congenital heart disease. We report the heart transplant single-center experience. The number of transplantations has increased over the last 3 decades. The Kaplan-Meier survival curves in the first, second, and third decades at 5 and 10 years were 69% and 59%, 62% and 52%, and 66% and 60%, respectively.
