Abstract

 Background: We studied the relations between net-atrioventricular compliance (Cn) and balloon mitral valvuloplasty (BMV) and tested effects of Cn on mitral valve area by proximal isovelocity surface area (MVAPISA) and pressure half time (MVAPHT) before and after BMV.

Methods and Results:

Thirty-six BMV candidates were studied. Echocardiography was done before, immediately after BMV for all patients and 1-month after BMV for 13 patients. MVA was calculated invasively, (MVAGorlin, reference method), by planimetry (MVAPLN), in addition to PHT and PISA. Differences from MVA-PLN were calculated as d-PHT and d-PISA and Cn was calculated (1270 X (MVA-PLN/E-slope). Mean age was 36.1 &plus... view more»
