Isolated congenital ventricular diverticulum or aneurysm is rare and usually arises from the left ventricle. The presentation of this condition is diverse. We report three cases of isolated congenital left ventricular diverticula. The age range was 17-30 years. Chest X-ray provided the earliest clinical suspicion in these three cases of a cardiac anomaly which was diagnosed by echocardiography and confirmed by angiocardiography. The location of the congenital left ventricular diverticulum was the left ventricular apex in two cases and basal in the other. We conclude that congenital left ventricular diverticulum is a disease of protean presentations. A high index of suspicion is necessary while interpreting chest X-rays and echocardiographs to diagnose congenital left ventricular diverticulum. A contractile accessory chamber of the left ventricle with a narrow neck with or without midline defects and an electrocardiogram without Q waves is consistent with the diagnosis of congenital left ventricular diverticulum.
孤立性先天性心室憩室或动脉瘤较为罕见，通常起源于左心室。这种疾病的表现多种多样。我们报告三例孤立性先天性左心室憩室病例。年龄范围为17至30岁。胸部X线检查最早在这三例病例中提示心脏异常，经超声心动图诊断并经心血管造影证实。先天性左心室憩室的位置，两例位于左心室尖部，另一例位于基部。我们得出结论，先天性左心室憩室是一种表现多样的疾病。在解读胸部X线和超声心动图以诊断先天性左心室憩室时，需要高度怀疑。左心室的一个有狭窄颈部且有或无中线缺损的收缩性附属腔室以及无Q波的心电图与先天性左心室憩室的诊断相符。
