Peculiarities of deformity of the left ventricle (LV) walls were studied in 93 patients in various variants of hypertrophic cardiomyopathy (HCMP). In accordance to complex echocardiography data, including vector-echocardiography, in HCMP the deformity grade and quantity of the affected segments of the LV myocardium have had depended directly on the stenosis degree of the LV tractus deferens (TD). Initially, a capacity for deformity lowers in basal segments of interventricular septum and in the LV anterior wall. While progressing of the LV TD obstruction, other myocardium segments become involved in the process, what is accompanied by deepening of the cardiac insufficiency (CI) severity. In maximal affection of myocardium and mostly expressed signs of CI gradient of systolic pressure in LV TD have had eliminated, in spite of presence of the LV expressed hypertrophy.
对93例不同类型肥厚型心肌病（HCMP）患者左心室（LV）壁畸形特点进行了研究。根据包括向量超声心动图在内的综合超声心动图数据，在HCMP中，LV心肌受累节段的畸形程度和数量直接取决于LV流出道（TD）的狭窄程度。最初，室间隔基底段和LV前壁的变形能力降低。随着LV TD梗阻的进展，其他心肌节段也参与到这一过程中，同时心脏功能不全（CI）的严重程度也随之加深。尽管LV有明显肥厚，但在心肌最大程度受累且CI症状最明显时，LV TD的收缩压梯度消失。
