Right heart chamber geometry and tricuspid annulus morphology in patients undergoing mitral valve repair with and without tricuspid valve annuloplasty

Aims of this study are to assess right atrial, right ventricular and tricuspid annulus geometry and function in patients undergoing mitral valve repair without or with tricuspid valve annuloplasty.

We studied 103 patients undergoing mitral valve (MV) surgery without (G1: 54 cases) or with (G2: 49 cases) concomitant tricuspid valve (TV) annuloplasty and 40 healthy subjects as controls.

Patients undergoing MV surgery and TV annuloplasty had an increased tricuspid annulus (TA) dimensions and a more advanced remodeling of right heart chambers probably reflecting an advanced stage of the disease.
