During left ventriculography, post-infarction left ventricular aneurysms present as diastolic deformations of the ventricular contour which, when accentuated during systole, give rise to paradoxical systolic expansion. The volumic consequences of thie parietal dyskinesia were studied in 10 cases of chronic anterior wall aneurysm. The borders of the aneurysm were determined by Watson's technique: diastolic and systolic volumes and endocardial surface areas were measured using a computer. In 9 out of 10 cases, neither volume nor endocardial surface area of the aneurysm varied from diastole to systole. Systolic distension of the aneurysm was observed in only one case. In the remainder, paradoxical systolic expansion was related to a charge in the shape of the aneurysm and to overall movement of the heart. The angiographic observations are important for the understanding of the physiopathology of post-infarction aneurysm and for choice of techniques for surgical treatment.
在左心室造影检查中，心肌梗死后左心室室壁瘤表现为心室轮廓的舒张期变形，这种变形在收缩期加剧时会导致矛盾性收缩期扩张。我们对10例慢性前壁室壁瘤患者壁运动障碍的容量影响进行了研究。采用沃森技术确定室壁瘤边界：使用计算机测量舒张期和收缩期容积以及心内膜表面积。10例患者中有9例，室壁瘤的容积和心内膜表面积在舒张期到收缩期均无变化。仅1例观察到室壁瘤的收缩期扩张。其余病例中，矛盾性收缩期扩张与室壁瘤形状的改变以及心脏的整体运动有关。血管造影观察结果对于理解心肌梗死后室壁瘤的病理生理学以及手术治疗技术的选择具有重要意义。
