RESUMEN

Considering suggested formula in the references and PCWP measured by catheterism, in the present study the relation between pulmonary capillary wedge pressure [PCWP] measured the flow velocity of mitral valve and mitral annulus motion through tissue doppler imaging is evaluated. 52 cases of severe MS were admitted for Balloon Mitral Valvolotomy [BMV] are included in this study. Mean age was 35 +/- 5 years consisting of 40 females and 12 males. Valve area, Pulmonary artery systolic pressure [PAP], E [Maximum Velocity of mitral valve at the beginning of diastole] and Em [Maximum rate of mitral annular motion at the beginning of diastole which is recorded through septal or lateral wall cumulus site] velocity and left atrial [LA] size were also measured by echocardiography and PCWP and PAP through catheterism. All patients had normal ejection fraction [EF] and coronary arteries; there was no other valvular diseases and shunts. There was a significant correlation between PAP in echocardiography and catheterism. Mean PAP was 53 +/- 19 mmHg in echocardiography and 53.9 +/- 17.8mmHg in catheterism. There wasn't any correlation between PCWP in echocardiography and catheterism [P=0.33] and also no relation between PCWP and mitral valve area [MVA] or LA size [P=0.2]. E/Em ratio increased in severe MS cases. E/Em ratio and suggested formula would overestimate the wedge pressure so echocardiography is not a reliable method for measuring PCWP in severe MS. Em velocity and E/Em ratio may be used for estimating MS severity
