    Abstract

    Background:Rheumatic mitral stenosis severity has been assessed by the systolic time interval between the QRS onset and the first heart sound (QS1) by phonocardiography. We hypothesized that non-invasive computerized acoustic cardiography could evaluate mitral stenosis severity compared with echocardiography and invasive haemodynamics in patients undergoing percutaneous transvenous mitral commissurotomy (PTMC). Methods:27 patients underwent computerized acoustic cardiography, echocardiography, and invasive haemodynamic measurements prior to and after PTMC. Results:The mean age was 31±10 years, and 21 (78%) were female. By echocardiography, mitral valve area increased from 0.82±0.14 to 1.50±0.24 cm2 (p
