Özet

Using tissue Doppler echocardiography, we evaluated left ventricular long-axis function in 65 mitral stenosis patients, 30 of whom were in sinus rhythm and 35 of whom were in chronic atrial fibrillation. There were 35 healthy control subjects. Conventional echocardiography was used to evaluate left ventricular diameters, left atrial diameters, left ventricular ejection fractions, and mitral valve areas. Tissue Doppler echocardiography was used to evaluate isovolumetric contraction time (ICT), isovolumetric relaxation time (IRT), ejection time (ET), and peak systolic myocardial velocities. The myocardial performance index was calculated with the formula (ICT + IRT)/ET.
