Cierre percutáneo de fugas periprotésicas con el dispositivo Amplatzer Vascular Plug III: resultados inmediatos y a corto plazo / Paravalvular leak closure with the Amplatzer Vascular Plug III device: immediate and short-term results

Introducción y objetivos: El cierre percutáneo de las fugas periprotésicas presenta tasas de éxito variables, la falta de dispositivos específicamente diseñados para este procedimiento ha limitado sus resultados. El Amplatzer Vascular Plug III, por sus características, parece un dispositivo ideal para este procedimiento, pero los datos disponibles se limitan a casos aislados o pequeñas series. El propósito de este estudio es analizar la factibilidad y la eficacia del cierre percutáneo de fugas periprotésicas con este dispositivo. Métodos: Se analizan resultados de seguridad y eficacia durante el procedimiento y a 90 días de las fugas periprotésicas mitrales y aórticas cerradas percutáneamente con este dispositivo en nuestro centro. Resultados: Se trataron 34 fugas periprotésicas, 7 a nivel aórtico y 27 a nivel mitral, correspondientes a 33 pacientes. El éxito técnico fue del 93,9% (en 2 pacientes se realizó un segundo procedimiento programado) y el éxito del procedimiento (reducción ≥ 1 grado de regurgitación) en el 90,9%. En 4 pacientes se observaron complicaciones relacionadas con el procedimiento (transfusión en 3 pacientes y cirugía por interferencia con los discos en 1 paciente). No se observó ningún caso de muerte, infarto de miocardio o accidente cerebrovascular periprocedimiento. A 90 días la supervivencia fue del 100%, y en el 90,3% de los pacientes mejoró la clase funcional; 4 pacientes sufrieron complicaciones vasculares (seudoaneurisma) en el seguimiento. Conclusiones: El cierre percutáneo de la fugas periprotésicas con el Amplatzer Vascular Plug III es un procedimiento factible, seguro y con elevadas tasas de éxito clínico y ecocardiográfico

Introduction and objectives: Percutaneous paravalvular leak closure is a complex procedure with varying success rates; the lack of closure devices specifically designed for this purpose has hampered this technique. The characteristics of the Amplatzer Vascular Plug III appear to be well suited for paravalvular leak closures; however, the available data are limited to case reports or small series of patients. The aim of this study was to analyze the feasibility and efficacy of paravalvular leak with this device. Methods: The immediate and 90-day safety and efficacy of mitral and aortic paravalvular leak closures performed with this device at our hospital were analyzed. Results: Percutaneous repair of 34 paravalvular leaks (27 mitral, 7 aortic) was attempted in 33 patients. The device was successfully implanted in 93.9% (in 2 patients, a second planned procedure was needed), and successful closure (defined as regurgitation reduction ≥ 1 grade) was achieved in 90.9% of patients. Complications included emergency surgery due to disc interference (n=1) and blood transfusion (n=3). There were no reports of procedure-related death, myocardial infarction, or stroke. At 90 days, survival was 100%, and 90.3% of patients showed significant clinical improvement; 4 patients developed vascular complications (pseudoaneurysm). Conclusions: Mitral and aortic paravalvular leak closure with the Amplatzer Vascular Plug III is feasible and safe, with high clinical and echocardiographic success rates
