The Relationship of Anatomic Localisation of Left Ventricular Aneurysm to Coronary Artery Lesions and Electrocardiographic Infarct Localisation

Fifty patients (46 male, 4 female) with ischemic heart disease and left ventricular aneurysm demonstrated by coronary angiography and contrast ventriculography (CV) were included in this study. The relation of anatomic localisations of left ventricular ancurysms to coronary artery lesions, electrocardiographic infarct localisation, and sustained ST-segment elevation were studied. It was shown that apical, anterior, and inferior ancurysms were most frequent and were associated with three-vessel or diffuse coronary artery lesions. The most frequently involved arteries were left anterior descending artery in cases of anterior and apical aneurysms and right coronary artery in those of inferior and inferolateral aneurysms. The incidence of sustained ST-segment elevation was found to be 42 %. A significant correlation existed between the anatomic and electrocardiographic localisations of left ventricular aneurysms.
