The application of real-time three-dimensional echocardiography (RT 3DE) in the diagnosis of double orifice mitral valve (DOMV) was explored. Five cases of DOMV were examined by using 2-dimensional echocardiography (2DE) and RT 3DE. The spatial morphology of malformed mitral valve and its change in hemodynamics were observed. DOMV associated with partial atrioventricular septal defect was found in 3 cases (in which 2 cases had cleft mitral valve) and isolated DOMV in 2 cases; and moderate to severe mitral regurgitation was detected in 3 cases, and mild mitral regurgitation in 1, and no regurgitation in 1 case; 1 case had complicated rhumatic heart disease. Three cases were preoperatively discovered by 2DE, while 2 missed (1 case was discovered postoperatively). Four cases were diagnosed by RT 3DE preoperatively, and 1 case was diagnosed postoperatively (not examined by RT 3DE preoperatively). It was suggested that RT 3DE is a reliable technique in the diagnosis of DOMV; it permitted comprehensive and noninvasive assessment of mitral valve and may supplement 2D TTE in the assessment of DOMV.
探讨实时三维超声心动图（RT 3DE）在双孔二尖瓣（DOMV）诊断中的应用。应用二维超声心动图（2DE）及RT 3DE对5例DOMV患者进行检查，观察二尖瓣畸形的空间形态及其血流动力学变化。发现3例DOMV合并部分房室间隔缺损（其中2例合并二尖瓣裂），2例孤立性DOMV；3例检测到中重度二尖瓣反流，1例轻度二尖瓣反流，1例无反流；1例合并风湿性心脏病。2DE术前发现3例，漏诊2例（1例术后发现）。RT 3DE术前诊断4例，1例术后诊断（术前未行RT 3DE检查）。提示RT 3DE是诊断DOMV的可靠技术；它可对二尖瓣进行全面、无创评估，在DOMV评估中可补充二维经胸超声心动图（2D TTE）。
