回顾性分析76例经彩色超声心动图检查诊断为右室双腔心( DCRV)患者的二维图像和多普勒特征,并与手术中探查做对比。结果显示患者均在二维切面显示右室流出道异常肥厚肌束或环状狭窄,彩色多普勒血流图像( CDFI)显示血流通过狭窄口时速度加快,呈五彩镶嵌色。经手术证实符合73例,1例超声诊断DCRV合并室间隔大缺损经手术证实为法洛四联症,1例DCRV合并室间隔膜周部缺损漏诊右冠窦瘤破裂,1例DCRV漏诊室间隔膜周部缺损。漏误诊率为3.9%。

76 cases of patients with right ventricular dual-chamber heart were analyzed by color Doppler echocar-diography, and their two-dimensional images and Doppler characteristics were compared with intraoperative find-ings. All patients were displayed in two dimensional surface that abnormal muscle bundle hypertrophy or narrow ring existed in the right ventricular outflow tract. When the blood flowed through thestenosis,it became faster and showed colorful mosaic blood on the CDFI. Compared with intraoperative findings,one case of tetralogy of Fallot was misdiagnosed as DCRV,two cases of misdiagnosis were right coronary sinus aneurysm and ventricular septal defect. The rate of misdiagnosis was 3 . 9%.
