Özet
Left ventricular (LV) torsion is a sensitive indicator of myocardial contractility and cardiac structure, and has recently been recognized as a sensitive indicator of cardiac performance. The aim of our study was to assess the effect of isolated mitral stenosis on LV torsion. We enrolled 19 patients with isolated mitral stenosis and 19 age- and gender-matched healthy subjects in the study. All patients had a normal sinus rhythm. All study subjects underwent two-dimensional echocardiography. Basal and apical LV rotations and LV torsion were evaluated using speckle-tracking echocardiography. Demographic characteristics, basic echocardiographic measures of LV ejection fraction, LV wall thickness, and LV mass index were similar between the two groups. The degrees of LV torsion (11.3 +/- 4.7, 15.4 +/- 4.9A degrees, p=0.014) and LV basal rotation (-aEuro parts per thousand 3.7 A +/- 1.9, -aEuro parts per thousand 6.5 A +/- 2.1A degrees, p < 0.001) were significantly decreased in the mitral stenosis group. There was a moderate positive correlation between mitral valve area and LV torsion (r=0.531, p=0.019). We showed significant reductions in LV torsion and LV basal rotation in patients with mitral valve stenosis. Structural and anatomical changes occurring during the progression of mitral stenosis may be responsible for these impaired movements.
