摘　　要：本研究用经食道实时三维超声心动图(real-time three-dimensional transesophageal echocardiography,RT-3D-TEE)对非瓣膜病性房颤-二尖瓣反流(nonvalvular atrial fibrillation-mitral reflux,NVAF-MR)患者的心脏功能进行了评价。选取NVAF-MR患者40例为观察组及40例健康个体为对照组,两组患者均接受RT-3D-TEE检查。结果显示,观察组左房内径(LAD)、瓣环左右径(DAlPm)、瓣环周长(C3D)、瓣环面积(A2D)以及瓣环非平面角度(NPA)明显高于对照组,瓣环高度、对合指数明显低于对照组(P<0.05)。Logistics回归分析结果:LAD、DAlPm、A2D、对合指数与NVAF患者出现二尖瓣返流具有相关性。ROC曲线分析结果:LAD、对合指数对该类患者诊断具有较高灵敏度与特异度。因此认为,RT-3D-TEE技术可准确评估患者二尖瓣功能,LAD与对合指数具有较高的诊断灵敏度与特异度,A2D、DAlPm可能与NVAF患者发生二尖瓣返流存在相关性。The purpose of this paper is to evaluate the cardiac function of nonvalvular atrial fibrillation and mitral reflux(NVAF-MR)patients with the real-time three-dimensional transesophageal echocardiography(RT-3d-TEE).40NVAF-MR patients and 40healthy individuals were selected as the observation group and the control group.Patients in both groups received RT-3d-TEE examination.The results showed that left atrial diameter(LAD),anterolateral-posteromedial annulus diameter(DAlPm),three dimensional circumference(C3D),two dimensional area(A2D)and nonplanarity angle(NPA)in the observation group were significantly higher than those in the control group(P<0.05).The valvular height and coaptation index were significantly lower than those in the control group(P<0.05).The logistics regression analysis showed that LAD,DAlPm,A2Dand coaptation index were correlated with NVAF-MR.The ROC curve analysis showed that LAD and coaptation index had highly sensibility and specificity in the diagnosis of NVAF-MR patients.Therefore,it is believed that RT-3d-TEE technology can accurately assess the mitral valve function of patients,and the diagnosis of those patients with LAD and coaptation index has higher sensitivity and specificity.A2D,DAlPm may be correlated with mitral regurgitation in NVAF patients.
