Abstract
BACKGROUND: Carcinoid heart disease frequently necessitates right-sided valve replacement, but prosthesis choice remains debated. CASE SUMMARY: A 66-year-old woman with carcinoid heart disease underwent tricuspid and pulmonic valve replacement. Within 6 months, she developed severe bioprosthetic stenosis and regurgitation, far earlier than typically reported. DISCUSSION: After multidisciplinary review, the rapid failure was attributed to recurrent carcinoid valvulopathy. Mechanical valve replacement was considered but deferred because of patient preference and comorbidities. TAKE-HOME MESSAGE: This case illustrates unusually rapid bioprosthetic valve degeneration in carcinoid heart disease and supports considering mechanical valves in select patients.
