Description
Summary:Periprosthetic mitral valve regurgitation due to paravalvular leakage is one of the complications of valve replacement surgery. We report a series of 8 patients with severe symptomatic periprosthetic mitral regurgitation in whom surgery could not be performed because of the high risk. All patients were assigned to percutaneous closure of periprosthetic mitral valve leaks using an Amplatzer duct occluder. The procedure was successful in 5 patients. A significant reduction in periprosthetic regurgitation and a clinical improvement were observed in 4 of the patients. The procedure was unsuccessful in 3 patients: in 2 due to interference with the prosthesis discs; in the other, because it was not possible to pass through the leak. One of these 3 patients died a few hours after the procedure due to severe stroke. Percutaneous closure of paravalvular leakage in patients at a high surgical risk is technically feasible and has an acceptable clinical success rate. La insuficiencia mitral periprotésica secundaria a fugas perivalvulares es una complicación de la cirugía de reemplazo valvular. Presentamos una serie de 8 casos con insuficiencia mitral periprotésica severa y sintomática, rechazados para cirugía por alto riesgo y en los que se decidió el cierre percutáneo de la fuga periprotésica mitral. En todos se utilizó dispositivo Amplatzer de cierre ductal. El procedimiento fue exitoso en 5 de los pacientes. Se objetivó disminución significativa de la insuficiencia periprotésica y mejoría clínica en el seguimiento en 4 pacientes. Se fracasó en 3 (2 por interferencia con los discos de la prótesis y 1 por no poder atravesar la fuga), de los que 1 falleció a las pocas horas del procedimiento por ictus masivo. El cierre percutáneo de dehiscencias perivalvulares en pacientes con alto riesgo quirúrgico es un procedimiento técnicamente posible y con una tasa de éxito clínico aceptable.
