- 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.

- Comparative Analysis of the Complications of 5347 Endomyocardial Biopsies Applied to Patients After Heart Transplantation and With Cardiomyopathies: A Single-center Study(2012) FIORELLI, A. I.; BENVENUTI, L.; AIELO, V.; COELHO, A. Q.; PALAZZO, J. F.; ROSSENER, R.; BARRETO, A. C. P.; MADY, C.; BACAL, F.; BOCCHI, E.; STOLF, N. A. G.Introduction. Endomyocardial biopsy (EMB) plays an important role in allograft surveillance to screen an acute rejection episode after heart transplantation (HT), to diagnose an unknown cause of cardiomyopathies (CMP) or to reveal a cardiac tumor. However, the procedure is not risk free. Objective. The main objective of this research was to describe our experience with EMB during the last 33 years comparing surgical risk between FIT versus no-HT patients. Method. We analyzed retrospectively the data of 5347 EMBs performed from 1978 to 2011 (33 years). For surveillance of acute rejection episodes after HT we performed 3564 (66.7%), whereas 1777 (33.2%) for CMP diagnosis, and 6 (1.0%) for cardiac tumor identification. Results. The main complications due to EMB were divided into 2 groups to facilitate analysis: major complications associated with potential death risk, and minor complications. The variables that showed a significant difference in the HT group were as follows: tricuspid Injury (.0490) and coronary fistula (.0000). Among the no-HT cohort they were insufficient fragment (.0000), major complications (.0000) and total complications (.0000). Conclusions. EMB can be accomplished with a low risk of complications and high effectiveness to diagnose CMP and rejection after HT. However, the risk is great among patients with CMP due to their anatomic characteristics. Children also constitute a risk group for EMB due to their small size in addition to the heart disease. The risk of injury to the tricuspid valve was higher among the HT group.

I.; COELHO, G. H. B.; AIELLO, V. D.; BENVENUTI, L. A.; PALAZZO, J. F.; SANTOS JUNIOR, V. P.; CANIZARES, B.; DIAS, R. R.; STOLF, N. A. G.Introduction. Tricuspid regurgitation (TR) is the most commonly valvular dysfunction found after heart transplantation (HTx). It may be related to endomyocardial biopsy (EMB) performed for allograft rejection surveillance. Objective. This investigation evaluated the presence of tricuspid valve tissue fragments obtained during routine EMB performed after HTx and its possible effect on short-term and long-term hemodynamic status. Method. This single-center review included prospectively collected and retrospectively analyzed data. From 1985 to 2010, 417 patients underwent 3550 EMB after HTx. All myocardial specimens were reviewed to identify the presence of tricuspid valve tissue by 2 observers initially and in doubtful cases by a third observer. The echocardiographic and hemodynamic parameters were only considered for valvular functional damage analysis in cases of tricuspid tissue inadvertently removed during EMB. Results. The 417 HTx patients to 3550 EMB, including 17,550 myocardial specimens. Tricuspid valve tissue was observed in 12 (2.9%) patients corresponding to 0.07% of the removed fragments. The echocardiographic and hemodynamic parameters of these patients before versus after the biopsy showed increased TR in 2 cases (2/12; 16.7%) quantified as moderate without progression in the long term. Only the right atrial pressure showed a significant increase (P = .0420) after tricuspid injury; however, the worsening of the functional class was not significant enough in any of the subjects. Thus, surgical intervention was not required. Conclusions. Histological evidence of chordal tissue in EMB specimens is a real-world problem of relatively low frequency. Traumatic tricuspid valve injury due to EMB rarely leads to severe valvular regurgitation; only a minority of patients develop significant clinical symptoms. Hemodynamic and echocardiographic alterations are also less often observed in most patients.
- Case Report: The Challenge for Diagnosis of Myocarditis and Transplant Rejection After COVID Infection in a Heart-Transplanted Adolescent(2023) PEGADO, Helio Milani; SIQUEIRA, Adailson; NAVARAJASEGARAN, Joshua; BENVENUTI, Luiz Alberto; CASTRO, Claudia Regina Pinheiro; ARRIETA, Santiago Raul; GUTIERREZ, Paulo Sampaio; DOLHNIKOFF, Marisa; AIELLO, Vera Demarchi; JATENE, Marcelo Biscegli; AZEKA, EstelaPatients who have undergone organ transplantation are immunosuppressed hosts, leaving them at a higher risk of infections. SARS-COV-2 has been shown to affect heart-transplanted patients. In this case report, we present the case of a 14-year-old heart transplant recipient who developed signs and symptoms of heart failure, along with fatigue, after a COVID-19 infection. An endomyocardial biopsy was performed to diagnose rejection and to evaluate whether this was myocarditis due to SARS-COV-2. The biopsy showed intense acute cellular rejection (3R) and antibody rejection PAMR1 H+ but was negative for the SARS-CoV-2 virus. The patient received organ rejection therapy with high-dose methylprednisolone and human immunoglobulin. After treatment, her heart function recovered, with biopsy investigations showing a lower level of cellular rejection (1R).
conferenceObject SIBLINGS WITH RESTRICTIVE SYNDROME AND HYPERTROPHIC CARDIOMYOPATHY: A RARE CASE OF SUCCESSFUL HEART TRANSPLANTATION(2013) AZEKA, Estela; KAWASAKA, Ana Laura B. C.; TANAKA, Ana Cristina S.; PEREIRA, Alexandre C.; AIELLO, Vera D.; JATENE, Marcelo B.PURPOSE: To report the cases of siblings with restrictive syndrome who underwent heart transplantation and whose hearts had histological characteristics of hypertrophic cardiomyopathy (HCM). METHOD: Case1) A 7 year-old boy with recurrent pneumonias and cardiomegaly. Echocardiography showed features of restrictive cardiomyopathy. No pericardial commitment was found. Due to refractory congestive heart failure he was listed and successfully transplanted at the age 14. The analysis of the explanted heart revealed diffuse myocite disarray, with no septal asymmetry or subaortic obstruction. He is currently in clinical follow up for 5 years. Case 2) A 10 year-old female with exertion dyspnea, cyanosis and vomits. Due to the family history, she was referred for investigation. Restrictive cardiomyopathy was diagnosed. She was listed for heart transplant and successfully transplanted at the age of 13. The analysis of the explanted heart showed mild thickening of ventricular walls with no asymmetries or subaortic obstruction and several areas of myocyte disarray and fibrosis. She is currently in clinical follow up for 2 years. Blood samples of our patients were tested for mutations in genes MYH7, MYBPC and Troponin I (most frequently related to HCM in Brazil), but no alterations were found. CONCLUSION: HCM is a genetic condition related to mutations in genes that encode components of the sarcomere. It can rarely present with features of restrictive syndrome. Heart transplant is the therapeutic option for refractory congestive heart failure, before the evolution to pulmonary hypertension, with good clinical outcome.- The challenging diagnosis of Chagas disease reactivation in endomyocardial biopsies from heart-transplanted patients(2017) BENVENUTI, Luiz Alberto; AIELLO, Vera Demarchi
- Successful Endomyocardial Biopsy Guided by Transthoracic Two-Dimensional Echocardiography(2011) FIORELLI, A. I.; COELHO, G. B.; SANTOS, R. H. B.; OLIVEIRA JR., J. L.; AIELO, V.; BENVENUTI, L.; OLIVEIRA, A. S.; SILVA, M. A. F. Da; CHIZZOLA, P. R.; COSTA, R.; MATHIAS JR., W.; BACAL, F.; BOCCHI, E. A.; STOLF, N. A. G.Introduction. Two-dimensional (2-D) echocardiography is an excellent alternative method to perform endomyocardial biopsies (EB) in special situations, mainly when the patient is in a critical state and cannot go to the catheterization laboratory or when there are contraindications to the use of fluoroscopy as in the pregnancy. Objective. This single-center experience analyzed the last 25 years use of an EB technique guided by echocardiography realized at the bedside on critical patients. Methods. From 1985 to 2010, we performed 76 EB guided by 2-D echocardiography on 59 patients, among whom 38 (64.4%) were critically ill with examinations at the bedside; among 10 (16.9%) subjects, the procedure was carried out simultaneously with fluoroscopy for safety's sake during the learning period. In addition, 8 (13.6%) were unavailable for fluoroscopy, and 3 (5.1%) required a hybrid method due to an intracardiac tumor. Results. The main adverse effects included local pain (n = 4, 5.6%); difficult out successful puncture due to previous biopsies (n = 4, 5.6%); local hematoma without major consequences (n = 3, 4.2%); failed but ultimately successful puncture on the first try due to previous biopsies or (n = 3, 4.2%); obesity and immediate postoperative period with impossibility to pass the bioptome into the right ventricle; however 2 days later the procedure was repeated successfully by echocardiography (n = 1, 1.4%). All myocardial specimens displayed suitable size. There were no undesirable extraction effects on the tricuspid valve tissue. In this series, there was no case of death, hemopericardium, or other major complication as a direct consequence of the biopsy. Conclusion. 2-D echocardiography is a special feature to guide EB is mainly in critically ill patients because it can be performed at the bedside without additional risk or disadvantages of fluoroscopy. The hybrid method associating 2-D echocardiography and fluoroscopy allows the procedure in different situations such as intracardiac tumor cases.
