Advancing a Bulky Delivery System Using a Novel Technique During Percutaneous Pulmonary Valve Implantation.

ABSTRACT: During percutaneous pulmonary valve implantation, it is challenging to advance the delivery system loaded with a stent-valve through the right ventricular outflow tract. An extra-stiff wire can provide enough supporting and stable positioning to prevent the displacement of the guide wire in stent-valve delivery. In the 2 cases reported here, we used a snare to trap the extra-stiff wire and a large sheath to support the snare; thus, the extra-stiff wire was pulled to the distal end and provided strong support for the advancement of the delivery system. After 8 months of follow-up, the patients were in good condition with excellent valve function. We named this novel, efficient technique the "parallel anchor sheath snare" technique. This report highlights a novel delivery strategy for patien
