Concomitant aortic valve procedures in patients undergoing implantation of continuous-flow left ventricular assist devices: An INTERMACS database analysis.

ABSTRACT:

Background

Management of existing aortic insufficiency (AI) and mechanical aortic valves in patients undergoing left ventricular assist device (LVAD) implantation remains controversial. Surgical options to address these issues include closure, repair or replacement of the valve.

Methods

Continuous-flow LVAD/biventricular VAD patients entered into the INTERMACS database between June 2006 and December 2012 were included (n = 5,344) in this analysis. Outcomes were compared between patients who underwent aortic valve (AV) closure (n = 125), repair (n = 95) and replacement (n = 85).

Results

Among patients who underwent an AV procedure, actuarial survival was significantly reduced for AV closures (63.2%) compared with AV repairs (76.8%) and replacements (71.8%) (p = 0.0003)
