[Characteristic features of the pathological anatomy and involvement of the myocardium in anomalous branching of the left coronary artery from the pulmonary trunk (Clinico-anatomical comparisons)].

Pathologic, clinical and anatomical correlations are presented for left ventricular affection in abnormal origin of the left coronary artery from the pulmonary trunk. It was revealed that there is a complex of critical factors essential for survival of patients and clinical pattern of the defect including the degree of manifestation of intercoronary collateral circulation, specificity of myocardial left ventricular ischemic impairment and that of mitral structure. Clinical and anatomical comparisons are drawn between the degree of affection of the left ventricular myocardium and its functional capacity.
