The presence of a mass in the left ventricular outflow tract is often a sign of severe pathology. The authors report 4 cases illustrating this echocardiographic diagnosis. In bacterial or mycotic endocarditis these masses suggest either aortic valve vegetations or prolapse of an aortic cusp. Two causes may be observed in patients with aortic bioprostheses: paravalvular leak with rocking of the sewing ring and destruction of the bioprosthetic cusps. In the 4 cases presented hemodynamic and angiographic investigations were contra indicated because of the risk of embolism of bacterial vegetations. Echocardiography gave precise diagnosis of the causal disease process and led to early surgical cure. Correlations between the anatomical and echocardiographic appearances are described and discussed.
左心室流出道出现肿物通常是严重病变的迹象。作者报告了4例说明这种超声心动图诊断的病例。在细菌性或霉菌性心内膜炎中，这些肿物提示主动脉瓣赘生物或主动脉瓣叶脱垂。在主动脉生物瓣置换患者中可观察到两种病因：缝合环摆动导致的瓣周漏和生物瓣叶破坏。在所呈现的4例病例中，由于细菌性赘生物有栓塞风险，血流动力学和血管造影检查均为禁忌。超声心动图对病因性疾病过程做出了精确诊断，并实现了早期手术治愈。文中描述并讨论了解剖学表现与超声心动图表现之间的相关性。
