To estimate frequency of the posterior mitral valve leaflet prolapse in routinely performed left ventriculography, 1000 consecutive ventriculograms of the right anterior oblique projection were analyzed. A group of patients consisted of 511 women and 489 men at mean age 46,5 years. Clinical diagnosis of heart lesions, myocardial disease, pulmonary hypertension or arrhythmias were indications for hemodynamic studies. In the investigated group of patients, there were no patients with clinical diagnosis of the coronary artery disease. Prolapse of the posterior mitral valve leaflet was diagnosed in 59 patients. Idiopathic mitral valve prolapse was diagnosed in 10 patients. Prolapse of the posterior mitral valve leaflet was most frequent in atrial septal defect (16.6%), myocardial lesion (12.5%), and after mitral commissurotomy (8.9%). Posterior mitral valve leaflet prolapse is not a frequent anomaly in routinely performed left ventriculography. Relatively often occurrence of the mitral valve prolapse in atrial septal defect and only occasional in the aortic lesions and dilated cardiomyopathy seems to point out at a role of the left ventricle size in pathogenesis of this syndrome.
为评估在常规进行的左心室造影检查中二尖瓣后叶脱垂的发生率，对连续1000例右前斜位的心室造影片进行了分析。研究组患者包括511名女性和489名男性，平均年龄46.5岁。心脏病变、心肌病、肺动脉高压或心律失常的临床诊断是进行血流动力学研究的指征。在该研究组患者中，无临床诊断为冠状动脉疾病的患者。59例患者被诊断为二尖瓣后叶脱垂。10例患者被诊断为特发性二尖瓣脱垂。二尖瓣后叶脱垂在房间隔缺损（16.6%）、心肌病变（12.5%）和二尖瓣交界切开术后（8.9%）最为常见。二尖瓣后叶脱垂在常规进行的左心室造影检查中并非常见异常。二尖瓣脱垂在房间隔缺损中相对常见，而在主动脉病变和扩张型心肌病中仅偶尔出现，这似乎表明左心室大小在该综合征发病机制中起作用。
