Percutaneous closure of paravalvular leaks has emerged as an alternative to repeated surgeries. Different percutaneous techniques and various devices have been used, off-label, for paravalvular leak closure. For mitral leaks, ante grade transseptal, retrograde transfemoral, and retrograde transapical techniques have been developed. In the ante grade transseptal approach, an arteriovenous guide wire loop is often created to advance the delivery sheath. In retrograde transfemoral closure, the wire in the left atrium is usually snared after transseptal puncture, to pull it from the femoral vein. The delivery sheath and closure device will subsequently be deployed from the left atrium. Each of these procedures takes time, is costly, and increases the risk of complications.
