Balloon-assisted paravalvular leakage crossing for transcatheter closure: a pilot study.

Abstract

Objectives. Transcatheter closure of paravalvular leaks (PVL) is an established treatment method. However, because of the frequent anatomical complexity of the PVL channel and lack of dedicated equipment, PVL crossing remains challenging. This study aims to provide an initial assessment of the safety and efficacy of using an angioplasty balloon to facilitate PVL passage. Methods. The authors describe 12 cases of predilatation of the PVL tract using a coronary balloon after an attempt to pass the sheath was unsuccessful. Results. In each case, the procedure was successful with final implantation of the occluder. No adverse events directly related to the technique were observed. Conclusions. The technique of traversing the PVL channel using small coronary balloons may be an effective alternative method. Results of this registry are a preview of further research into the development and improvement of the described technique.
