A 58-year-old woman with a history of mechanic mitral prosthesis and tricuspid prosthetic ring annuloplasty presented functional impairment and lower limbs edema. A transthoracic echocardiogram showed dilatation of right ventricle with preserved systolic function and severe eccentric tricuspid regurgitation with an unclear mechanism. Transesophageal echocardiogram revealed a partial dehiscence of the prosthetic ring. Three-dimensional (3D) “in face” reconstruction of tricuspid valve allowed an exact characterization of the defect and the design of adequate surgical strategy.
There is increasing evidence of significant postoperative residual tricuspid regurgitation. Some reports have mentioned dehiscence of the prosthetic ring as an infrequent mechanism that eventually could requires reoperation. For this reason, its diagnosis is relevant, and novel techniques such as three-dimensional echocardiography can significantly help in the decision-making process.
