Common ventricle is a rare congenital anomaly in which the ventricular chamber receives blood from two separate atrioventricular valves or from a common atrioventricular valve. We used contrast echocardiography during cardiac catheterization to confirm ventricular anatomy and to characterize blood flow dynamics in 35 patients with common ventricle. After injections of dye, a cloud of echoes anterior to the mitral valve echo during the rapid inflow phase of ventricular diastole is indirect evidence of common ventricle with two atrioventricular valves. Common ventricle with an outflow chamber is characterized by a smaller ventricular chamber visualized anterior to both atrioventricular valves which opacifies with subsequent ventricular systole. The arrival of all dye posterior to the only recorded atrioventricular valve further established the presence of a single atrioventricular valve. These contrast flow patterns gave greater specificity to the standard M-mode echocardiographic assessment of patients suspected of having common ventricle.
共同心室是一种罕见的先天性异常，其心室腔从两个独立的房室瓣或一个共同的房室瓣接受血液。我们在心脏导管插入术期间使用对比超声心动图来确认心室解剖结构并描述35例共同心室患者的血流动力学特征。注射染料后，在心室舒张期快速充盈阶段二尖瓣回声前方出现的一团回声是存在两个房室瓣的共同心室的间接证据。有流出腔的共同心室的特征是在两个房室瓣前方可见较小的心室腔，随后心室收缩时该腔会显影。所有染料在唯一记录的房室瓣后方到达进一步证实了存在单个房室瓣。这些对比血流模式为疑似患有共同心室的患者的标准M型超声心动图评估提供了更高的特异性。
