Abstract

Amplatzer Paravalvular leak (PVL) plug is rectangular in shape, that might suit closure of crescentic PVL. Among 79 transcatheter PVL closures from a single center, a subgroup of 16 patients who received Amplatzer PVL plugs were analyzed. All procedures were successful, as the plug auto-oriented to the leak, without mechanical leaflet interference, though needing additional 31 devices. Two patients needed an elective re-intervention. NYHA class improved from III-IV before procedure to less than II after procedure. Complications were not directly related to the Amplatzer PVL plug. The rectangular shape for crescentic leaks, auto-orientation and non-interference with mechanical leaflets were good attributes.

Keywords: Crescentic shape; Oblong plug; Periprosthetic leak.
