Combined Transcatheter Tricuspid and Pulmonary Valve Replacement

Abstract

Background:

For patients with combined tricuspid and pulmonary valve disease, operative intervention carries high mortality risk. Published reports of combined transcatheter tricuspid and pulmonary valve replacement have been limited to single cases.

Methods:

A retrospective chart review was performed including all patients undergoing combined transcatheter tricuspid and pulmonary valve replacement at the Ahmanson/UCLA Adult Congenital Heart Disease Center.

Results:

Combined transcatheter tricuspid and pulmonary valve replacement was undertaken in five adult patients (median age: 46 years; range: 24-64 years). Three had congenital heart disease and two had carcinoid syndrome. Four patients had previous surgical tricuspid valve replacement and one had a surgical incomplete annuloplasty ring. Four patients had previous surgical pulmonary valve replacement and one had a right ventricle-to-pulmonary artery homograft conduit. Two patients underwent Medtronic Melody valve implantation in both tricuspid and pulmonary positions and three underwent Edwards Sapien S3 implantation in both tricuspid and pulmonary positions. Valve implantation was successful in all. Follow-up ranged from 0.9 to 3.0 years. One patient underwent redo transcatheter tricuspid valve replacement 12 months after the first transcatheter intervention for progressive regurgitation of a Melody valve. This patient died 2.5 years after combined valve placement of complications from refractory heart failure. The remaining patients were alive and free of valve reintervention at follow-up.

Conclusions:

Combined transcatheter tricuspid and pulmonary valve replacement can be performed successfully, with an acceptable complication rate. This strategy is a feasible option for appropriately selected patients.
