Stuck mechanical tricuspid valve prosthesis: the valve that does not move.

A 44-year–old woman underwent mitral valve and tricuspid valve (TV) replacement 6 years earlier using an ATS bileaflet tilting disc prostheses (ATS Medical Inc., Minneapolis, MN) for combined valvular stenosis and regurgitation because of rheumatic heart disease. On a routine clinic visit, the patient reported progressive fatigue and pedal edema over the previous few weeks. On physical examination, she was hemodynamically stable with evidence of elevated jugular venous pressure, hepatomegaly, and 3-mm pitting ankle and leg edema. Cardiac auscultation revealed closing and opening mechanical clicks; however, mitral and tricuspid clicks could not be distinguished. A grade 2/6 holodiastolic rumble and a
