A Modified Buddy-Wire Technique for Crossing of the Interatrial Septum With the Sapien 3 Valve During Transseptal Mitral Valve-in-Valve/Ring Procedures.

ABSTRACT:

Background

Crossing of the interatrial septum (IAS) with the Edwards Sapien-3 transcatheter heart valve (THV) may fail, despite preparatory balloon septostomy. A planned buddy guidewire placed in the left ventricle may help facilitate crossing of the IAS and mitral bioprosthesis with the THV.

Methods

A retrospective study of 12 consecutive patients undergoing transseptal, mitral valve-in-valve or valve-in-ring procedures using the Edwards Sapien-3 THV since 2018 with a planned buddy-wire technique. The primary endpoint was the composite of successful delivery of the buddy wire and deployment of the first intended Sapien 3 within the mitral valve without removal from the body, additional interatrial septal puncture, or placement of a further buddy wire.
