摘要
目的:探讨风湿性二尖瓣和主动脉瓣病变继发三尖瓣功能性返流的影响因素及影像诊断特点。方法:77例风湿性二尖瓣、主动脉瓣病变,均作二维超声心动图、超声多普勒和远达X线胸片检查,根据超声诊断有否三尖瓣功能性返流分为两组,对相关指标进行单因素和多因素分析。结果:单因素分析:三尖瓣返流组与无返流组之间,二尖瓣病变类型、左房内径(LAD)、心胸比率、肺动脉段凸度、左心耳凸度、右房高/心高比率、右下肺动脉干宽径及双重影、肺水肿的比率有显著性差异,P值均小于0.05;而病程、心房纤颤、瓣膜病变部位、左室收缩末径(LVDS)、左室舒张末径(LVDD),返流组和无返流组间无显著性差异。多因素分析:二尖瓣病变类型、心胸比率、肺动脉段凸度与三尖瓣功能性返流密切相关。结论:二尖瓣狭窄、心脏增大程度和肺动脉高压是风湿性二尖瓣病变继发三尖瓣功能性返流的主要相关因素和预测因子。
Objective： To investigate the influence factors and the imaging diagnostic characteristics of rheumatic mitral and aortic valve diseases with fuctional tricuspid regurgitation （TR）. Methods： 77 patients with rheumatic mitral and aortic valve diseases who underwent transthoracic echocardiography and heart teleoroentgenogram were divided into TR group and no TR group according to the echocardiograhic diagnosis. The statistic was analyzed by using t-test, chi-square test and logistic regression. Results： There was significant difference betwcen TR group and no TR group for the pattern of mitral disease, LAD, the convex degree of pulmonary tnmk and loft aoride, right atrium height/cardiac height/cardiac height ratio, trasverse diameter of right lower pulmonary artery, double atrial shadow, and pulmonary edena, but no significat difference between the two groups for the cause of disease, atrial fibrillation, LVDS and LVDD. Multivariate analysis showed functional TR had imitate correlation with the pattem of mitral valve disease, cardio-thoracic ratio and the convex degree of pulmoary trunk. Conclusion： Mitral valve stenosis, cardiae dilation and pulmonary hypertension were the significant risk factors and predictors for rheumatic mitral and aortic valve diseases with secondary TR.
