Mitral valve repair is an important operative procedure for correcting mitral regurgitation (MR). However, serial change of residual MR after operation has not been reported. Serial change of MR after mitral valve repair was evaluated by transesophageal color Doppler echocardiography (TEE). Twenty-six patients undergoing mitral valve repair for MR during 1987 to 1991 were examined by TEE just after operation, 6 months after operation, and late follow-up period (mean 3.7 years). Thirteen patients had a lesion of the anterior mitral leaflet before operation (group A). Thirteen patients had a lesion of the posterior mitral leaflet before operation (group P). The MR area was measured by TEE at each stage after operation. In group A, the MR area at late follow-up increased significantly compared with just after operation (1.1 vs 4.3 cm2, p < 0.001). In group P, the MR area at late follow-up did not increase significantly compared with just after operation (0.6 vs 1.3 cm2, p = NS). In conclusion, MR does not increase after mitral valve repair in patients with posterior mitral valve repair, but MR may increase at late follow-up after operation for anterior mitral valve prolapse.
二尖瓣修复术是纠正二尖瓣反流（MR）的一项重要手术操作。然而，术后残余MR的系列变化尚未见报道。通过经食管彩色多普勒超声心动图（TEE）评估二尖瓣修复术后MR的系列变化。对1987年至1991年间接受二尖瓣修复术治疗MR的26例患者在术后即刻、术后6个月及晚期随访期（平均3.7年）进行TEE检查。13例患者术前存在二尖瓣前叶病变（A组）。13例患者术前存在二尖瓣后叶病变（P组）。术后各阶段均通过TEE测量MR面积。在A组，晚期随访时的MR面积与术后即刻相比显著增加（1.1 vs 4.3 cm²，p < 0.001）。在P组，晚期随访时的MR面积与术后即刻相比未显著增加（0.6 vs 1.3 cm²，p = 无显著性差异）。总之，二尖瓣后叶修复患者二尖瓣修复术后MR不增加，但二尖瓣前叶脱垂术后晚期随访时MR可能增加。
