Impact of atrioventricular compliance on clinical outcome of patients undergoing successful percutaneous balloon mitral valvuloplasty.

Objective: We aimed to assess the impact of atrioventricular compliance (Cn) on the clinical outcome, after successful percutaneous balloon mitral valvuloplasty (PBMV).

Methods And Results: Using Doppler echocardiography Cn was estimated from the equation that has been previously validated. Mitral valve area (MVA), tricuspid annular plane systolic excursion (TAPSE), pulmonary artery pressure (PAP), and degree of tricuspid regurgitation (TR) severity were evaluated before, immediately, and every 6 months with a median duration of 32 months after successful PBMV in 150 consecutive patients.
