摘　　要：目的 :评价风湿性瓣膜病患者二尖瓣返流与左房血栓形成的关系。方法 :在经胸超声的基础上 ,应用多平面经食道超声检查 48例非巨大左房 (LA <60mm)的二尖瓣疾病患者 ,比较分析二尖瓣返流程度与血栓形成的相关关系。结果 :合并二尖瓣大量返流的风湿性瓣膜病人较少出现左房血栓和 或左房自发声学显影。结论 :二尖瓣大量返流的风湿性心脏病患者形成左房血栓的可能性减低 ,因而是一种保护机制。Objective:The aim of this study was to test the hypothesis that mitral regurgitation(MR)has a protective effect on the development of left atrial thrombus (LAT)in patients with rheumatic heart disease and without giant left atrium.Methods:Transthoracic and transesophageal echocardiography were performed in 48 patients with mitral valve disease to relate the presence of LAT and MR.Results:Significant MR had a protective effect against thromboembolism.Conclusion:In patients with mitral valve disease,significant MR protects against LAT formation.
