摘  要:目的探讨常规及经胸实时三维超声心动图在Ebstein畸形诊断中的应用价值。方法 2007年3月至2014年7月拟在阜外心血管病医院外科手术矫治Ebstein畸形患者61例,同时采集门诊正常成人20例作为对照。常规超声及经胸实时三维超声评价右心室大小、功能及三尖瓣反流。常规超声分析参数包括右心室前后径(RV)、三尖瓣环横径(TV-R)、反流分级及瓣叶下移距离。经胸实时三维超声检查测量计算右心室舒张末容积(EDV)、右心室收缩末容积(ESV)、右心室舒张末容积指数(EDVI)、右心室收缩末容积指数(ESVI)、右心室每搏量(SV)、三尖瓣环面积(TV-A)、三尖瓣反流口血流束横截面积(EROA)。结果经胸实时三维超声心动图可立体显示三尖瓣对合面、瓣环大小及瓣叶立体结构。61例患者中仅32例获得完整右心室容积数据,余29例采集右心室三维图像不完整。三尖瓣反流5级(重度)34例(55.7%);4级(中重度)16例(26.2%);,3级(中度)11例(18.1%),平均(4.4±0.7)级。与正常成人比较,Ebstein畸形患者右心室EDV、ESV、EDVI、ESVI、SV、RV、TV-R明显增大[(273.5±77.7)ml vs(74.3±15.9)ml,(187.1±96.8)ml vs(31.1±9.2)ml,(177.4±53.6)ml/m2 vs(43.4±8.2)ml/m2,(121.7±65.5)ml/m2vs(18.4±5.1)ml/m2,(95.9±20.2)ml vs(43.6±8.8)ml,(48.1±13.3)ml/m2 vs(19.0±1.9)ml/m2,(56.4±8.9)ml/m2 vs(28.5±4.3)ml/m2],差异有统计学意义(P均<0.05);右心室射血分数(EF)明显减低[(38.3±12.8)%vs(59.3±5.1)%,P=0.000];EROA与RV、RV/LV显著相关(r=0.6910、0.6471,P均<0.05)。结论经胸实时三维超声可显示Ebstein畸形患者三尖瓣的瓣叶畸形特征和右心室功能,作为常规超声的重要补充,为临床诊断及功能评估提供依据。Objective To explore the value of conventional echocardiography and transthoracic real-time three-dimensional echocardiography(RT3DE) in diagnosis of Ebstein anomaly. Methods We investigated the morphology and function of right ventricle(RV) as well as the structure, morphology and regurgitation of tricuspid valve in 61 adult patients with Ebstein anomaly before surgery by using conventional echocardiography and transthoracic RT3 DE. Twenty normal adults were enrolled as control group. Results The surface of the tricuspid leafl ets, the morphology of the tricuspid annulus as well as the threedimensional structure of the tricuspid valve were displayed stereoscopically by RT3 DE. Complete RV volume data could be acquired in 32 patients of Ebstein anomaly. The apex or part of RV could not be contained in the remaining 29 patients. Thirty-four(55.7%) patients with Ebstein anomaly had severe tricuspid regurgitation, 16(26.2%) patients had moderate to severe regurgitation, and 11(18.1%) patients had moderate regurgitation. Compared with the normal adults, patients of Ebstein anomaly showed higher RV end-diastolic volume(EDV), end-systolic volume(ESV), end-diastolic volume index(EDVI), end-systolic volume index(ESVI), stroke volume(SV), RV anterior-posterior diameter(RV), tricuspid valve annular transverse diameter(TV-R), and lower RV ejection fraction(EF) [(273.5±77.7) ml vs(74.3±15.9) ml,(187.1±96.8) ml vs(31.1±9.2) ml,(177.4±53.6) ml/m^2 vs(43.4±8.2) ml/m^2,(121.7±65.5) ml/m^2 vs(18.4±5.1) ml/m^2,(95.9±20.2) ml vs(43.6±8.8) ml,(48.1±13.3) ml/m^2 vs(19.0±1.9) ml/m^2,(56.4±8.9) ml/m^2 vs(28.5±4.3) ml/m^2,(38.3±12.8) % vs(59.3±5.1) %, all P 0.05). The tricuspid regurgitant orifice fl ow cross-sectional area(EROA) were correlated positively with RV anterior-posterior diameter(r=0.691), ratio of RV and LV anterior-posterior diameter(RV/LV)(r=0.6471). Conclusion Transthoracic
