Cardiac Remodeling and Prognosis in Secondar Tricuspid Regurgitation

Inclusion Criteria: * Any patients ≥ 18 years old, with moderate to severe tricuspid regurgitation (≥ 2/4), agreeing to participate ; * The patients included can be ambulatory patients or stabilized hospitalised patients (meaning patient clinicaly stable, not decompensated, and whose normovolemia has been checked). * Non opposition of the patient Exclusion Criteria: * Patient whose accoustic window is judged by the operator as incompatible with a precise evaluation of the tricuspid regurgitation or anatomy of the right cavity ; * TR \< grade 2 ; * TR secondary to primary pulmonary hypertension or congenital cardiopathy ; * Primary tricuspid regurgitation (due to rheumatic heart disease, medication - included benfluorex, due to endocarditis, valvular prolapse, carcinoid syndrom or a cardiac stimulation lead …) ; * Significant left heart valvulopathy (Mitral regurgitation \> grade 2, Aortic insufficiency \> grade 2, Mitral stenosis \< 2 cm², Aortic stenosis \< 1.5 cm²). A valvulopathy sucessfully operated isn't considered as an exclusion criteria; * Cardiopathy with significative systolic dysfunction (FE\< 40%) ; * Patients whose life expectantcy is less than 1 year due to a pathology independent of the TR (neoplasic process for example) ; * Patient under judicial protection.
