Objectives:
We share our center's experience with the use of transcatheter valvular therapies in the setting of failed bioprostheses.
Background:
As medicine continues to advance, the lifespan of individuals continues to increase, and current surgical valvular therapies begin to degrade prior to a person's end of life. It is important to evaluate the efficacy and durability of transcatheter valves within failed surgical bioprostheses.
Methods:
Baseline characteristics, periprocedural complications, and long-term outcomes were collected and assessed in patients who received transcatheter valves for failing surgical aortic valve bioprostheses and mitral valve and ring bioprostheses from March 2011 to July 2018.
Results:
From our cohort of 1048 patients, we identified 45 individuals (4.3%) who underwent transcatheter replacement of a failed bioprosthetic valve or ring. Mean age at presentation was 80.8 ± 10.7 years and 75.5 ± 9.3 years, mean STS score was 9.3 ± 5.1 and 13.3 ± 8.7, and mean time to failure was 12.0 ± 5.2 years and 7.3 ± 4.5 years for aortic and mitral positions, respectively. At 1 year, time to event analysis suggested a 16.4% mortality rate for aortic replacement and 12.8% mortality rate for mitral replacement.
Conclusions:
We demonstrate outcomes from one of the largest single-center United States based cohorts of transcatheter replacements of failed surgical bioprostheses. Our center has demonstrated that it is feasible to pursue the replacement of failed surgical bioprostheses in the aortic and mitral positions with transcatheter valves given appropriate patient selection.
