A left ventricular, mass-like echocardiographic density (a pseudotumor), present only during diastole and not attached to any intracardiac structure, was present in 77 of 1,820 consecutive 2-dimensional echocardiograms performed with a rotating-head transducer. Evaluation of the patients with a pseudotumor demonstrated that aortic insufficiency of mild to moderate degree was the most commonly associated lesion. Of the 61 patients with aortic insufficiency in our series, 69% had a left ventricular pseudotumor. Of the cases with a pseudotumor and aortic insufficiency, none had severe aortic insufficiency. Of the 1,759 patients without aortic insufficiency, a left ventricular pseudotumor was present in 2%. In our series, the sensitivity of left ventricular pseudotumor for aortic insufficiency was 69% and the specificity was 98%.
在使用旋转头换能器进行的1820例连续二维超声心动图检查中，有77例出现仅在舒张期存在且不附着于任何心内结构的左心室团块状超声心动图密度（假肿瘤）。对有假肿瘤的患者进行评估发现，轻至中度主动脉瓣关闭不全是最常见的相关病变。在我们系列研究的61例主动脉瓣关闭不全患者中，69%有左心室假肿瘤。在有假肿瘤和主动脉瓣关闭不全的病例中，无一例有严重主动脉瓣关闭不全。在1759例无主动脉瓣关闭不全的患者中，2%有左心室假肿瘤。在我们的系列研究中，左心室假肿瘤对主动脉瓣关闭不全的敏感性为69%，特异性为98%。
