Aortic Valve Reoperation After Stentless Bioprosthesis: Short- and Long-Term Outcomes.

ABSTRACT:

Background

Limited data are available regarding outcomes for stentless aortic valve reoperation. The reported reoperative mortality has been unacceptably high.

Methods

Between 1997 and 2017, a retrospective analysis was performed on 143 patients who underwent open aortic valve reoperations for failed stentless aortic valve bioprostheses. We evaluated both short-term and long-term outcomes on this cohort of patients.

Results

Bicuspid aortic valve was present in 107 of 143 patients (75%) at the time of the initial Freestyle (Medtronic, Minneapolis, MN) procedure, and 120 of 143 patients (84%) underwent a modified inclusion aortic root replacement procedure. The interval from first operation to reoperation was 9 years (range, 5.4 to 11.8), which was significantly shorter
