ABSTRACT
Introducción: El cateterismo intervencionista corrige las cardiopatías complejas, donde el dispositivo Amplatzer es el más usado y está disponible en Cuba. Objetivo: Evaluar el cateterismo intervencionista con Amplatzer, en el cierre de la comunicación interauricular ostium secundum. Métodos: Estudio de evaluación, longitudinal y prospectivo en 92 pacientes. El cierre de la comunicación por cateterismo con Amplatzer, se realizó en el Cardiocentro Pediátrico William Soler (2010-2016). Se utilizaron variables demográficas, ecocardiográficas (transtorácicas y transesofágicas) antes, durante y al año del cateterismo. Se observaron las complicaciones. La evaluación clínica y ecocardiográfica se realizó al año poscateterismo. Los pacientes a quienes se les realizó el proceder en el 2016, se evaluaron a los 6 meses. Resultados: Se encontraron diferencias significativas en el sexo (p<0,05): femenino 64,1 por ciento con homogeneidad para la edad (p= 0,244): media 9,8 años ( 5 desviaciones estándar. Precateterismo: 28,3 por ciento eran desnutridos y 17,4 por ciento delgados; poscateterismo la desnutrición mejoró significativamente (p= 0,000): desnutridos 9,8 por ciento y delgados 8,7 por ciento. El diámetro medio del defecto por ecocardiografía transcateterismo fue significativo (p= 0,000). Transcateterismo: 98,9 por ciento con cierre de defecto, 16,3 por ciento con insuficiencia tricúspidea y 4,3 por ciento con insuficiencia mitral. Poscateterismo: 98,9 por ciento con Amplatzer bien colocado. Hubo complicaciones inmediatas en 8,7 por ciento (arritmias, derrame pericárdico y embolización). Al año se detectó cortocircuito residual pequeño (n= 1) e insuficiencias valvulares auriculoventriculares (n= 3). La evolución fue satisfactoria (n= 91). Conclusiones: La evolución del cierre de la comunicación interauricular ostium secundum con dispositivo Amplatzer es satisfactoria, con mejoras de la desnutrición(AU)
Introduction: The interventional catheterization corrects complex heart diseases, and the Amplatzer device is the most widely used and is available in Cuba. Objective: To assess the interventional catheterization with Amplatzer device in the ostium secundum atrial septal closure. Methods: Longitudinal and prospective evaluation study in 92 patients. The closure of the communication by Amplatzer catheterization was performed in the William Soler Pediatric Cardiocenter of (2010-2016). Demographic and echocardiographic (transthoracic and transesophageal) variables were used before, during, and at the year of the catheterization. Complications were observed. Clinical and echocardiographic assessment was made a year after catheterism. The patients who underwent the procedure in 2016 were evaluated at 6 months. Results: Significant differences were found in the sex (p< 0.05): Female 64.1 t percent with homogeneity of the age (p= 0.244): average 9.8 years ( 5 standard deviations. Pre-catheterism: 28.3 percent were malnourished and 17.4 percent thin; post-catheterism: malnutrition improved significantly (p= 0.000): 9.8 percent malnourished and 8.7 percent thin. The average diameter of the defect by transcatheter echocardiography was significant (p= 0.000). Transcatheter: 98.9 percent : with default closure, 16.3 percent with tricuspid insufficiency and 4.3 percent with mitral regurgitation. Post-catheterism: 98.9 percent with Amplatzer device correctly positioned. There were immediate complications in 8.7 percent (arrhythmia, pericardial effusion, and embolization). A year after, small residual short circuit was detected (n= 1), and atrioventricular valve regurgitation (n= 3). The evolution was satisfactory (n= 91). Conclusions: The evolution of ostium secundum atrial septal defect´s closure with Amplatzer device is satisfactory and improves malnutrition(AU)

Abstract Objectives: To compare the advantages and disadvantages of perventricular and percutaneous procedures for treating isolated ventricular septal defect (VSD). Methods: A total of 572 patients with isolated VSD were selected in our hospital between January 2015 and December 2016. The patients' median age and weight were five years (1-26 years) and 29 kg (9-55 kg), respectively. The median diameter of VSD was 6.0 mm (5-10 mm). Patients were divided into two groups. In group A, perventricular device closure was performed in 427 patients; in group B, 145 patients underwent percutaneous device closure. Results: Four hundred twelve patients in group A and 135 patients in group B underwent successful closure. The total occlusion rate was 98.5% (immediately) and 99.5% (3-month follow-up) in group A, which were not significantly different from those in group B (97.7% and 100%, respectively). Patients in group A had longer intensive care unit (ICU) stay than those in group B, but patients in group B experienced significantly longer operative times than those in group A. The follow-up period ranged from 8 months to 1.5 year (median, 1 year). During the follow-up period, late-onset complete atrioventricular block occurred in two patients. No other serious complications were noted in the remaining patients. Conclusion: Both procedures are safe and effective treatments for isolated VSD. The percutaneous procedure has obvious advantages of shorter ICU stay and less trauma than the perventricular procedure. However, the perventricular procedure is simpler to execute, results in a shorter operative time, and avoids X-ray exposure.

FUNDAMENTO: A oclusão percutânea do apêndice atrial esquerdo (OAAE) surgiu como alternativa à anticoagulação oral (AO) para prevenção do acidente vascular cerebral (AVC) em pacientes com fibrilação atrial não-valvular (FANV). OBJETIVO: Relatar os resultados imediatos e o seguimento clínico de pacientes submetidos a OAAE com o Amplatzer Cardiac Plug (ACP) em um único centro de referência. MÉTODOS: Oitenta e seis pacientes consecutivos com FANV, contra-indicação à AO e escore CHADS2= 2,6±1,2 foram submetidos a OAAE com implante de ACP. Realizou-se seguimento clínico e ecocardiográfico no mínimo 4 meses após o implante. RESULTADOS: Todos os implantes foram guiados apenas por angiografia. O sucesso do procedimento foi de 99% (1 insucesso por tamponamento cardíaco e consequente suspensão da OAAE). Houve 4 complicações maiores (o tamponamento já referido, 2 AVCs transitórios e uma embolização com retirada percutânea da prótese) e duas menores (um derrame pericárdico sem tamponamento e uma pequena comunicação interatrial evidenciada no seguimento). Houve 1 óbito hospitalar após 6 dias, não relacionado à intervenção. Todos os outros pacientes receberam alta sem AO. Após seguimento de 25,9 pacientes-ano (69 pacientes) não houve AVCs nem embolizações tardias de próteses. O AAE estava completamente ocluído em 97% dos casos. Seis pacientes apresentaram evidência de trombo sobre a prótese, que desapareceram após reinstituição de AO por 3 meses. CONCLUSÃO: OAAE se associa a um alto índice de sucesso, um índice aceitável de complicações e resultados promissores a médio prazo, podendo ser considerada uma alternativa válida à OA na prevenção do AVC em pacientes com FANV.
BACKGROUND: Percutaneous left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation (OA) for prevention of thromboembolic stroke in patients with non-valvular atrial fibrillation (NVAF). OBJECTIVE: To describe the immediate results and short- to medium-term clinical follow-up (FU) of patients that underwent LAAC with Amplatzer Cardiac Plug (ACP) implantation in a single reference center. METHODS: Eighty-six consecutive patients with NVAF, contraindication to OA, and CHADS2 score=2.6±1.2 underwent LAAC with ACP implantation. Clinical and echocardiographic FU was performed at least four months after the procedure. RESULTS: All implants were guided by angiography alone. Procedural success was 99% (one patient suffered a cardiac tamponade requiring pericardiocentesis, and the procedure was waived). There were four major complications (the already mentioned cardiac tamponade, two transient ischemic attacks and one device embolization with percutaneous retrieval) and two minor complications (one pericardial effusion without clinical significance and one non-significant ASD evidenced at FU). There was one in-hospital death after six days, unrelated to the procedure. All other patients were discharged without OA. After 25.9 patient-years of FU (69 patients), there were no strokes and no late device embolization. The LAA was completely closed in 97% of the cases. Six patients showed evidence of thrombus formation on the device, which resolved after three months of OA. CONCLUSION: LAAC is associated with high success, acceptable complication rates, and promising FU results, and may be considered a valuable alternative or complement to OA for stroke prevention in patients with NVAF.
