本文对98例冠状动脉粥样硬化性心脏病急性心肌梗塞合并左室部分破裂的标本进行了研究。在90例中，单个结构（所谓的孤立性破裂）破裂如下：左心室游离壁52例，室间隔18例，乳头肌20例。8例同时有两个结构破裂，最常见的组合是室间隔和左室壁破裂。乳头肌破裂以下外侧梗死多见，室间隔破裂以前间隔梗死多见。20例室间隔破裂均为室壁梗死，乳头肌破裂20例中11例为室壁下梗死。乳头肌破裂类型与梗死类型之间无相关性。在临床上，室间隔破裂和乳头肌破裂的病例中，循环衰竭是常见的。当乳头肌完全受累或室间隔受累时，破裂后一周内死亡是常见的。乳头肌部分破裂，10例中有2例观察到较长的生存期（月）。
Ninety-eight specimens with rupture of some portion of the left ventricle complicating acute myocardial infarction from atherosclerotic coronary disease were studied. In 90, a single structure (so-called isolated rupture) had ruptured as follows: free wall of left ventricle, 52 cases; ventricular septum, 18 cases; a papillary muscle, 20 cases. In eight cases, two structures had ruptured, the most common combination being rupture of ventricular septum and left ventricular wal. Inferolateral location of underlying infarction was the common situation in ruptured papillary muscle, while anteroseptal myocardial infarction was more common in rupture of the ventricular septum. Transmural infarction underlay each case of ruptured ventricular septum, while in ruptured papillary muscle 11 of 20 cases showed subendocardial infarction. There was no association between the type of papillary muscle rupture and the type of infarct. Clinically, collapse of the circulation was common in cases of ruptured ventricular septum and ruptured papillary muscle. Death within one week after rupture was usual when the papillary muscle was involved totally or when the ventricular septum was involved. With partial rupture of a papillary muscle, longer survival (months) was observed in two of ten cases.
