Bioprosthetic tricuspid valve stenosis: a case series.

ABSTRACT: Bioprosthetic tricuspid valve stenosis is a late sequela of tricuspid valve replacement (TVR); however, detailed information regarding its clinical picture is lacking. Thirty-one patients with bioprosthetic TVR (mean age: 60.5 ± 16.6 years, male/female: 11/20) were followed-up for 79.5 ± 49.1 months (14-188 months). Eleven patients developed bioprosthetic tricuspid valve stenosis (mean tricuspid gradient >5 mmHg) at a median interval of 96 months (interquartile range: 61-114 months). The mean tricuspid gradient at the time of tricuspid valve stenosis diagnosis was 10.9 ± 3.9 mmHg. Although the mid-term tricuspid valve stenosis-free survival was favourable (92.4% at 60 and 78.7% at 84 months), it had declined steeply to 31.5% by 120 months. Ten out of 11 tricuspid valve stenosis patients sh
