A series of 100 consecutive patients demonstrating total occlusion of the proximal left anterior descending coronary artery by cineangiography were analyzed. Forty-five showed occlusion proximal to the first septal branch. Collaterals to the anterior descending vessel were present in 83 cases. Left ventriculography revealed normal contractility in 16 cases and localized aneurysms in twenty-two. In 18 instances the left anterior descending lesion was the only occlusion demonstrated. Double and triple vessel involvement was present in 35 and 45 respectively. Normal EKGs were seen in 22 cases and signs of transmural anterior infarction in forty-two. Neither the development of ventricular aneurysm nor the presence of anterior wall infarction by EKG appeared to be influenced by the site of occlusion with respect to the septal branch. All the patients with normal left ventricular contractility had demonstrable collaterals.
对100例经电影血管造影显示左前降支近端完全闭塞的连续患者进行了分析。45例显示闭塞位于第一间隔支近端。83例存在向前降支血管的侧支循环。左心室造影显示16例收缩功能正常，22例有局限性室壁瘤。18例中左前降支病变是唯一显示的闭塞病变。分别有35例和45例存在双支和三支血管受累。22例心电图正常，42例有透壁前壁梗死征象。心电图显示的室壁瘤形成和前壁梗死的存在似乎均不受相对于间隔支的闭塞部位的影响。所有左心室收缩功能正常的患者均有可显示的侧支循环。
