Forty-eight patients with double-chambered right ventricle (DCRV) were prospectively studied over a 3-year period. Clinical, echocardiographic, hemodynamic, and angiographic studies were done in all. Three patients were studied postoperatively also. Fifteen patients underwent surgery confirming the diagnosis. Echocardiography detected anomalous muscle bundles (AMBs) in 39/41 patients in whom this study was carried out. Angiographically AMBs were best demonstrated in anteroposterior views in a systolic frame. Common associated anomalies found with DCRV were ventricular septal defects (69%), pulmonary valve stenosis (38%), and double-outlet right ventricle (10%).
在3年的时间里，对48例双腔右心室（DCRV）患者进行了前瞻性研究。对所有患者均进行了临床、超声心动图、血流动力学和血管造影研究。其中3例患者术后也进行了研究。15例患者接受了手术，从而确诊。在进行这项研究的41例患者中，超声心动图检测到39例存在异常肌束（AMB）。血管造影显示，在收缩期帧的前后位视图中，AMB显示最佳。与DCRV常见的相关异常包括室间隔缺损（69%）、肺动脉瓣狭窄（38%）和右心室双出口（10%）。
