Poor Late Outcomes After Tricuspid Valve Repair in a Single Ventricle: Experience of 103 Patients

Abstract

Background: Outcomes of tricuspid valve repair in single-ventricle palliation are poor. We sought to identify the impact of repair technique and primary mechanisms of regurgitation on outcomes after surgery. Methods: A retrospective review of medical records across 4 centers undertaking single-ventricle palliation in Australia and New Zealand was performed. Patients with a dominant right functional single ventricle undergoing tricuspid valve repair between January 1991 and March 2019 were identified. Results: One hundred three patients met inclusion criteria, with a median follow-up duration of 6.7 years (interquartile range, 1.5-12.4). Mechanism of regurgitation was structural in 30 patient..
