Aim: The aim of this paper is to introduce new technic of mitral paravalvular leak (MiPVL) closure using steerable electrophysiologic

catheter.

Method and Results: We made six attempts to close MiPVL. Procedure was performed under general anesthesia with simultaneous

monitoring of 3D transesophageal echocardiography (RT3DTEE) except one. In five cases, we didnot cross MiPVL in a standard manner,

only in one case we have been succefull applying the conventional technique. In all cases we were able to pass the channel MPVL

from the left atrium into the left ventricle. In one case, we made the closure twice, because the Amplatzer VSD occluder interfered with

a disc of mitral valve. All five MiPVL we have successfully closed with Amplatzer vascular plug (AVP III). In two cases we achieved complete

closure PVL, in three cases a small residual MiPVL persisted.

Conclusion: Closing MiPVL using a new technique with steerable electrophysiological catheter and RT3DTEE monitoring simplifies the

entire process. Concomitant use of AVP III improves the success of the whole procedure.
