室间隔或左室乳头肌破裂是急性心肌梗塞的一种严重的并发症。两者都有新出现的收缩期杂音,临床鉴别常有困难。室间隔穿孔时突然发生肺部的再循环,乳头肌破裂时突然发生二尖瓣关闭不全,因而都可发生循环衰竭。为探讨两者的鉴别,作者搜集了急性心肌梗塞并发左心室破裂共98例加以分析,其中90例破裂仅限于一处,例如左室游离壁、室间隔或乳头肌(孤立性穿破),另8例
Ventricular septal or left ventricular papillary muscle rupture is a serious complication of acute myocardial infarction. Both have emerging systolic murmur, clinical identification often difficult. Ventricular septal perforation occurs suddenly when the lungs recirculate, papillary muscle rupture occurs when mitral regurgitation, which can occur circulatory failure. To explore the differential between the two, the authors collected 98 cases of acute myocardial infarction with left ventricular rupture analyzed, of which 90 cases were only limited to one rupture, such as left ventricular free wall, ventricular septum or papillary muscle (isolated perforation) Another 8 cases
