    Abstract:
    Little is known about the gender differences of left ventricular (LV) remodeling in patients with aortic valve calcification (AVC). The aim was to assess gender differences of structure functional changes and LV myocardial remodeling in patients with AVC depending on the type of valve lesion. 293 patients (131 men) with revealed AVC by transthoracic echocardioscopy without aortic stenosis and 76 patients (50 men) without AVC were examined. Men had normal geometry of LV more often than women (15.7% vs. 4.4 % in isolated AVC and 11.9% vs. 2.8 % in combined lesion of aortic valve (AV) and mitral valves ring (MVR), р<0.052), and eccentric hypertrophy was registered more often in man with combined AV and MVR lesion (38.1% vs. 15.5 % in women with combined AV and MVR lesion and vs. 20.2 % in men with isolated AVC, р<0.029). LV systolic function was worse in men with combined valves lesion (ejection fraction was 54.0 (48.0; 65.0) vs. 66.0 (60.0; 71.0) % in women with combined valves lesion and vs. 63.0 (55.0; 70.0) % in men with isolated AVC, р<0.022). Men with combined valves lesion also had a larger right ventricle (RV) size (RV index was 1.3 (1.2; 1.5) vs. 1.2 (1.1; 1.4) cm/m2 in women with combined valves lesion and vs. 1.2 (1.1; 1.4) cm/m2 in men with isolated AVC, р<0.036) and had tricuspid regurgitation more often (76.2% vs. 56.3 % in women with combined valves lesion and vs. 58.4 % in men with isolated AVC, р<0.029). Women had higher peak aortic jet velocity (1.5 (1.4; 1.7) vs. 1.4 (1.2; 1.6) m/s in man, р<0.0001). Dominating models of LV remodeling in women were concentric, mainly concentric hypertrophy (61.5% vs. 31.5 % in men in groups with isolated AVC and 64.8% vs. 31.0 % in combined valves lesion groups, р<0.001). Also women had a higher left auricle index than men (2.3 (2.0; 2.5) vs. 2.1 (1.9; 2.4) cm/m2, р<0.015). There were revealed differences in distribution of LV remodeling types depending on the gender and the type of valve lesion.
