Early Trifecta valve failure: Report of a cluster of cases from a tertiary care referral center
Aortic Valve Stenosis
Heart Valve Prosthesis
Heart Valve Prosthesis Implantation
Our findings provide further insights into the pathologic mechanisms leading to early Trifecta valve failure. In addition to tear of the noncoronary cusp of the Trifecta prosthesis described as the most common mechanism in the literature for its failure, circumferential pannus formation composed of fibrofatty tissue in the inflow portion and leaflet calcification concentrated around the posts in the outflow portion are important mechanisms contributing toward early Trifecta valve failure.
