Long-Term Outcomes and Modes of Failure of the Ross Operation in Patients with Aortic Insufficiency Joel Price MD, MPH, Laurent De Kerchove MD, David Glineur MD, PhD, Jean Rubay MD, and Gebrine El Khoury MD Department of Cardiovascular and Thoracic Surgery Cliniques St. Luc Brussels, Belgium
Background • Long-term durability of the Ross operation when performed for isolated aortic insufficiency has been questioned. • Especially important in the setting of a regurgitant bicuspid aortic valve • bicuspid aortopathy involves the pulmonary trunk
Methods • Isolated AI: AI (≥ 3+), absence of significant stenosis (mean gradient <30mmHg, AVA >1.5cm2) • Review of institutional database revealed 68 patients underwent Ross operation for AI • Mean follow-up 11.2 y, max follow-up 18.8y • Complete as of March 2011 • Statistical Anlysis: Kaplan-Meier, Log-rank and time-to-event
Outcomes • Long-term survival and Cardiac survial • Recurrent significant AI (autograft regurgitation) • Reoperation • Valve-related events: • Endocarditis, hemorrhage, thrombo-embolism • Sub group analysis: • Bicuspid vs tricuspid
Reoperations AVSRR = Aortic Valve Sparring Root Replacement, AV = Aortic Valve, AVR = Aortic Valve Replacement
Conclusions • Ross operation for isolated AI was associated with excellent survival and freedom from recurrent AI, reoperation and valve-related events • Bicuspid and tricuspid valves have equivalent outcomes • Main mechanisms of failure are AI and autograft dilation
