Echocardiographic features were studied in four patients with straddling tricuspid valve, a rare and complex cardiac anomaly that may defy diagnosis by angiocardiography. The most significant echocardiographic feature was a septal echo recorded at a depth corresponding to the midportion of the tricuspid valve with one of the tricuspid valve leaflets opening posterior to the ventricular septum in diastole. Certain of the features, which appear to be distinctive for this anomaly, have not previously been described.
对4例三尖瓣骑跨患者的超声心动图特征进行了研究，三尖瓣骑跨是一种罕见且复杂的心脏异常，可能难以通过心血管造影进行诊断。最显著的超声心动图特征是在相当于三尖瓣中部深度处记录到的室间隔回声，舒张期三尖瓣的一个瓣叶在室间隔后方开放。某些特征似乎是这种异常所特有的，此前尚未有过描述。
