- PEDIATRIC HEART TRANSPLANTATION PROGRAM: SINGLE CENTER EXPERIENCE OF 20 YEARS(2013) AZEKA, Estela; GALAS, Filomena; TANAMATI, Carla; PENHA, Juliano; FERNANDES, Marcos; SENAHA, Luciano; XAVIER, Johnny; DELGADO, Ana Beatriz Romani; KAJITA, Luiz; AIELLO, Vera; BENVENUTI, Luiz; MIURA, Nana; AULER JUNIOR, Jose Otavio Costa; JATENE, MarceloOBJECTIVE: Heart transplantation has been the treatment of choice for children with refractory to conventional therapy. To report the experience with heart transplantation in a single center. MATERIAL AND METHODS: To report the single center experience of hearttransplantation. Data analysis was demographic characteristics, clinical outcome and survival Kaplan Meier curve. RESULTS: From October 30, 1992 to October 2nd, 2012, 120 transplants were performed and 115 patients were submitted to heart transplantation at Heart Institute (InCor) University of Sao Paulo Medical School, Sao Paulo, Brazil. The causes of indication for transplantation were: cardiomyopathies (76%) and congenital heart disease (24%). Five patients were submitted to re-transplantation. Three of them were re-transplanted on the early postoperative period with high mortality (66.6%). One patient was submitted to simultaneous re-transplantation and kidney transplantation after 13.9 yrs of follow-up and one of patient was successful re-transplanted after 10 yr of follow-up. The post-operative immunosuppression regimen was double immunosuppression and polyclonal anti-thymocyte serum induction therapy. The actuarial survival was 80%, 71%, and 61% at 1, 5, and 10 yr, respectively. CONCLUSION: Heart transplantation has been a promising option for children. The use of double immunosuppression with polyclonal anti-thymocyte serum induction therapy combined with surveillance of acute rejection with non-invasive tests may provide favorable clinical outcome.
- 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.

- NEUROLOGICAL COMPLICATIONS AFTER PEDIATRIC HEART TRANSPLANTATION(2013) FERNANDES, Marcos; AZEKA, Estela; SENAHA, Luciano; DELGADO, Ana Beatriz Romani; GALAS, Filomena; GUIMARAES, Vanessa; HAJJAR, Ludmilha; TANAMATI, Carla; PENHA, Juliano; AULER JUNIOR, Jose Otavio Costa; JATENE, MarceloOBJECTIVES: Neurological complications can occur after pediatric heart transplantation and its outcome may cause disabilities and limit the prognosis of children who have undergone this procedure. The aim of the study is to evaluate the neurological complications during the first 30 days after the heart transplantation. MATERIAL AND METHODS: A survey was made at based on the InCor records to find the data. RESULTS: From September 2011 to September 2012, 15 heart transplants were performed at the Heart Institute (InCor) University of Sao Paulo Medical School. The mean age was 11.1± yr5.34 yrs, median 9.63 yrs. There were 8 (53.3%) males. The diagnosis for heart transplantation was 80% cardiomiopathies. Two of them wereë. re-transplantation. One patient was with ECMO before transplantation and one was with assist device. Seven of them were priority when listed for the heart transplantation. The immunosuppression therapy was calcineurin inhibitor and cytostatic drug. Induction therapy was performed with antithymocyte globulin. Eight (53%) of 15 patients developed neurological complications. The main cause were strokes in 37.5%. The other causes were anisocoria in 1 (12%) patient, ischemic vascular accident 1 (12%) patient, hemorrhagic vascular accident 1 (12%). Three (20%) of them died due to multiple organ failure and infection, two of them were in priority before transplant (one with assist device) and were intubated with renal failure and sedated. These two patients were the ones that showed the worse neurological complications after the transplant. CONCLUSION: Neurological complications were common after heart transplantation, patient can have favorable clinical outcome after treatment.
- Use of Short-term Circulatory Support as a Bridge in Pediatric Heart Transplantation(2015) CANEO, Luiz Fernando; MIANA, Leonardo Augusto; TANAMATI, Carla; PENHA, Juliano Gomes; SHIMODA, Monica Satsuki; AZEKA, Estela; MIURA, Nana; GALAS, Filomena Regina Barbosa Gomes; GUIMARAES, Vanessa Alves; JATENE, Marcelo BiscegliBackground: Heart transplantation is considered the gold standard therapy for the advanced heart failure, but donor shortage, especially in pediatric patients, is the main limitation for this procedure, so most sick patients die while waiting for the procedure. Objective: To evaluate the use of short-term circulatory support as a bridge to transplantation in end-stage cardiomyopathy. Methods: Retrospective clinical study. Between January 2011 and December 2013, 40 patients with cardiomyopathy were admitted in our Pediatric Intensive Care Unit, with a mean age of 4.5 years. Twenty patients evolved during hospitalization with clinical deterioration and were classified as Intermacs 1 and 2. One patient died within 24 hours and 19 could be stabilized and were listed. They were divided into 2 groups: A, clinical support alone and B, implantation of short-term circulatory support as bridge to transplantation additionally to clinical therapy. Results: We used short-term mechanical circulatory support as a bridge to transplantation in 9. In group A (n = 10), eight died waiting and 2 patients (20%) were transplanted, but none was discharged. In group B (n = 9), 6 patients (66.7%) were transplanted and three were discharged. The mean support time was 21,8 days (6 to 984h). The mean transplant waiting list time was 33,8 days. Renal failure and sepsis were the main complication and causeof death in group A while neurologic complications were more prevalent en group B. Conclusion: Mechanical circulatory support increases survival on the pediatric heart transplantation waiting list in patients classified as Intermacs 1 and 2.

B. G.; JATENE, Fabio B.; JATENE, Marcelo B.Introduction: Donor shortage and organ allocation is the main problem in pediatric heart transplant. Mechanical circulatory support is known to increase waiting list survival, but it is not routinely used in pediatric programs in Latin America. Methods: All patients listed for heart transplant and supported by a mechanical circulatory support between January 2012 and March 2016 were included in this retrospective single-center study. The endpoints were mechanical circulatory support time, complications, heart transplant survival and discharge from the hospital. Results: Twenty-nine patients from our waiting list were assessed. Twelve (45%) patients were initially supported by extracorporeal membrane oxygenation (ECMO) and a centrifugal pump was implanted in 17 (55%) patients. Five patients initially supported by ECMO were bridged to another device. One was bridged to a centrifugal pump and four were bridged to Berlin Heart Excor (R). Among the 29 supported patients, 18 (62%) managed to have a heart transplant. Thirty-day survival period after heart transplant was 56% (10 patients). Median support duration was 12 days (interquartile range [IQR] 4-26 days) per run and the waiting time for heart transplant was 9.5 days (IQR 2.5-25 days). Acute kidney injury was identified as a mortality predictor (OR=22.6 [CI=1.04-494.6]; P=0.04). Conclusion: Mechanical circulatory support was able to bridge most INTERMACS 1 and 2 pediatric patients to transplant with an acceptable complication rate. Acute renal failure increased mortality after mechanical circulatory support in our experience.

- CONGENITAL HEART DISEASE IN ADOLESCENT AND ADULTS: INDICATION FOR HEART TRANSPLANTATION AND CLINICAL OUTCOME(2013) FARHAT, Juliana; JATENE, Marcelo; FERNANDES, Marcos; SENAHA, Luciano; DELGADO, Ana Beatriz Romani; TANAMATI, Carla; AIELLO, Vera; BENVENUTI, Luiz; PENHA, Juliano; VALDO, Melinade Oliveira; BRITO, Pedro Thiago; AZEKA, EstelaOBJECTIVE: The aim of the study was to evaluate the patients who were submitted to heart transplantation due to congenital heart disease. MATERIAL AND METHODS: It was considered a retrospective analysis of the medical records of the patients who were submitted to heart transplantation at Heart Institute (InCor) University of Sao Paulo Medical School from 2002 through 2012. RESULTS: From 2002 through 2012, 115 patients have undergone heart transplantation at Heart Institute (InCor) University of Sao Paulo Medical School. Of those, 29 (25.2%) had congenital heart diseases, having one of them submitted to re-transplantation 9 yrs after transplantation. The mean age was 8.56 yrs old (range of 0.11–26.06). The assessed congenital heart diseases were: double outlet (three patients), hypoplastic heart syndrome (two patients), pulmonary atresia (two patients), ventricular septal defect (one patient), Ebstein anomaly (two patients),Uhl anomaly (one patient), congenital heart block (three patients), tetralogy of Fallot (one patient), av canal (one patient), complex congenital heart disease (12 patients). Twenty patients had submitted to cardiac surgery before transplantation. The mean ischemia time was 170.8 min. Thirteen patients (44.8%) died (due to surgical complications, heart failure due to acute rejection and multiple organ insufficiency). Mean follow-up period of 4.7 yrs. CONCLUSION: Heart transplantation is an indication for patients with congenital heart disease and allowed long term survival for this population.
- THE IMPACT OF TACROLIMUS AS RESCUE THERAPY IN CHILDREN USING DOUBLE IMMUNOSSUPRESSIVE REGIMEN AFTER HEART TRANSPLANTATION(2013) BRANCO, Klebia Castello; AZEKA, Estela; JATENE, Marcelo; TRINDADE, Evelinda; GALAS, Filomena Regina Barbosa Gomes; HAJJAR, Ludhmila Abrahao; BENVENUTI, Luiz; RISO, Arlindo; TANAMATI, Carla; PENHA, Juliano; AULER JUNIOR, Jose Otavio Costa; ATIK, EdmarOBJETIVE: The aim of this study was to evaluate the clinical outcome of children undergoing heart transplantation who required conversion from a cyclosporine-based steroid free therapy to a tacrolimus-based immunosuppressive regimen. MATERIAL AND METHODS: We performed a prospective observational cohort study in 28 children who underwent conversion from a cyclosporine- based steroid free therapy to a tacrolimus-based therapy for refractory or late rejection or intolerance to cyclosporine. RESULTS: There was complete resolution of refractory rejection episodes and adverse side effects in all patients. The incidence rate (x100) of rejection episodes before and after conversion was 7.98 and 2.11, respectively (p≤0.0001). Actuarial 1 month, 1 and 5 yr survival, in patients converted to tacrolimus was 100%, 96% and 85.5% respectively. CONCLUSION: Tacrolimus is effective as rescue therapy for refractory rejection and is a Terapeutic option for pediatric patients.
