| 目的 探讨实时三维超声心动图(RT-3DE)观察先天性双孔二尖瓣畸形(DOMV)的应用价值。方法 5例先天性DOMV患者,在常规二维超声心动图基础上,应用RT-3DE实时显像、全容积显像及彩色成像模式,观察畸形二尖瓣立体形态及血流动力学改变。结果 5例先天性DOMV中,3例合并部分型房室间隔缺损,2例为单纯性双孔二尖瓣;2例合并有瓣裂,无瓣裂者3例;5例患者均伴有不同程度的二尖瓣关闭不全(中-重度3例,轻度1例,功能正常1例)。术前二维超声提示3例DOMV,漏诊2例(其中1例术后复查时提示)。实时三维超声提示4例DOMV,1例术前未行实时三维超声检查,术后复查时提示。结论 与二维超声心动图比较,实时三维超声心动图能更全面、立体地显示二尖瓣的空间结构,提高对DOMV诊断的准确性,可作为传统二维超声心动图的重要补充。 |

| Objective To demonstrate the usefulness of real-time three-dimensional echocardiography (RT-3DE) in the diagnosis of double orifice mitral valve (DOMV). Methods Five DOMV cases were examined using 2DE and RT-3DE. Results DOMV associated partial atrioventricular septal defect was found in 3 cases (in which 2 had cleft mitral valve) and isolated DOMV in 2 cases, which had moderate to severe mitral regurgitation was in 3 cases, and mild mitral regurgitation in 1, no regurgitation in 1; 1 had complicated rhumatic heart disease; 3 cases were preoperatively discovered by 2DE, while 2 missed (1 case was discovered postoperatively); 4 cases were diagnosed by RT-3DE preoperatively, 1 case was diagnosed postoperatively (not examined by RT-3DE preoperatively). Conclusion RT-3DE is a reliable technique in the diagnosis of DOMV, which permits a comprehensive noninvasive assessment of mitral valve and may supplement 2D TTE in the assessment of DOMV. |
