目的探讨经胸及经食管超声心动图诊断二尖瓣脱垂六叶亚区分区的价值,并探讨二尖瓣脱垂不同亚区与二尖瓣反流之间的相互关系.方法选择二尖瓣脱垂伴中度以上二尖瓣反流患者33例,应用经胸及经食管超声心动图技术确定二尖瓣脱垂的亚区分叶并与术中结果进行比较,分析二尖瓣脱垂不同亚区与二尖瓣反流之间的相互关系.结果与术中结果相比较,经胸超声心动图及经食管超声心动图定性诊断二尖瓣脱垂的准确率均为100％,定位诊断二尖瓣脱垂亚区的准确率分别为80％和94％,经胸超声心动图及经食管超声心动图两种方法之间的检查结果差异有统计学意义(P＜0.05)；二尖瓣反流程度与二尖瓣脱垂不同亚区有关.结论经食管超声心动图较经胸超声心动图对二尖瓣脱垂部位进行亚区定位更有优势；二尖瓣反流程度与二尖瓣脱垂不同亚区有关.

Objective To evaluate the localization of mitral valvular(MV)prolapse by transthoracic echocardiography(TTE),transesophageal echocardiography(TEE)and explore the interrelationship between the different subregions of MV prolapse and mitral regurgitation(MR).Methods Total of thirtythree patients with MV prolapse and more than moderate MR were included.TEE was used to further judge the location of scallop lesions and the result of both TTE and TEE were compared with the surgical findings respectively.The relationship between the different subregions of MV prolapse and MR was analyzed.Results Compared with the surgery findings,the accuracy rate of TTE and TEE in diagnosis of MV prolapse was 100％ qualitatively,80％ for TTE and 94％ for TEE in localizing the diseased region with the anterior and posterior MV,the result of TEE was significantly different from TTE(P＜0.05).MR level was related to the location of MV prolapse.Conclusions Compared with the TTE,TEE had more advantages in localizing the position of the MV prolapse.Mitral regurgitation is related to the location of MV prolapse.
