Abstract 15348: Incidence For Prosthetic Valve Endocarditis in Between 365 Days After Isolated Aortic Valve Replacement: Differences Between Conventional and Tavi
Background: Prosthetic valve endocarditis after aortic valve replacement is a life-threatening disease with a high mortality rate.
Methods: Retrospective analysis comparing pre- and perioperative factors of all patients requiring isolated aortic valve replacement either via sternotomy as a conventionally aortic valve replacement (CAVR) or as a transcatheter aortic valve implantation (TAVI) between January 2006 and May 2011 in a single center.
Results: A total of 7852 patients underwent aortic valve replacement (AVR) including combined procedures e.g. coronary bypass grafting, rhythm surgery for atrial fibrillation, other valve procedures or surgery on the ascending aorta. 3746 patients (47.7%) of them had isolated AVR either conventionally (CAVR; n=2369) or transcatheter based (TAVI; n=1377). Surgery for acute infective endocarditis (AIE) in between 365 days after primary procedure was necessary in 21 patients: 4 in TAVI and 17 in CAVR. The incidence for AIE after isolated AVR was 0.56% (0.29% in TAVI and 0.72% in CAVR). The difference was highly significant (p=0.01).
Conclusions: Although TAVI is a procedure for high risk patients it has a significant lower incidence for AIE in between 365 days after aortic valve implantation than CAVR.
