【摘要】 对严重的二尖瓣关闭不全病人进行二尖瓣修补术与置换相比，有着明显的利益，然而，部分病例修补术后可能持续存在二尖瓣返流，且传统的术中评价二尖瓣修补术效果的方法往往不可靠。本组术中经食道超声心动图（TEE）发现二尖瓣修补术后仍有22％（2／9）的病例存在严重的二失瓣返流，根据这一信息．这2例病人当即进行了二尖瓣置换术。随访16～24个月，7例二尖瓣修补术的病人心功能一级，无需再次手术。因此，术中TEE技术是快速准确的评价瓣膜修补术效果的方法，保证了手术的成功，能使更多更复杂的病例进行二尖瓣修补术。更多还原

【Abstract】 Mitral valve repair provides substantial advantages over mitral valve replacement in patients with severe mitral regurgitation. However, mitral regurgitation may persist in some patients after repair. The traditionaly employed procedures for intraoperative assessment of the adequacy of mitral valve repair have not proved to be reliable approaches In the study, intraoperative transesophageal color Doppler flow mapping showed sever mitral regurgitation in 2/9(22% )patients after repair. Mitral valve replacement were performed in the 2 patients during the same thoracotomy according to the information of intraoperative color Dopper. The 7 patients of mitral valve repair were in New York Heart Association functional class 1 and unneccessary to reoperation during 16-24months follow-up. Therefore the technique of intraoperative transesophageal color Doppler flow mapping provided repair and accurate evaluation of the adequacy of mitral valve repair and ensured a sucessful of the operation and may allow mitral valve repair to be performed in greater numbers of patients and more complex abnormalities.更多还原
