Self-expandable Venus P-valve in Patient with Transposition of Great Arteries and Arterial Switch Operation.

Abstract

We report the successfull transcatheter pulmonary implantation of a self-expandable Venus P-valve in a patient with transposition of the great arteries, status post arterial switch operation in infancy. She had free pulmonary regurgitation, severely dilated right ventricle, and was in NYHA class II. After confirmation with the sizing balloon of the distensibility of the "choke point" at the main pulmonary anastomosis, the valve was implanted and became wedged, without compromising the final result. Follow-up confirmed the excellent result. This suggests that a self-expandable valve is an interesting alternative to balloon expandable valve for selected patients with such anatomy.
