title: [Mitral valve repair for mitral regurgitation].
abstract: In these 14 years, 54 adult patients, 28 males and 26 females, mean age 49.6 years old, underwent mitral valve repair for mitral regurgitation. Valve lesion consisted of 28 valve prolapse, 23 torn chordae, 4 ischemic lesion, 3 rheumatic changes, and 3 clefts. Valve prolapse near the commissure was repaired by Kay-Reed's annuloplasty in 31 patients. Torn chordae of the posterior leaflet was repaired by quadrangular resection of the leaflet in 21 cases. Commissural valve prolapse by torn chordae was treated by commissural resection and sliding repair of the leaflet in 5 patients. Torn chordae of the anterior leaflet was repaired by small triangular resection of the leaflet with artificial chordae using ePTFE suture or transfer of posterior chordae to the anterior leaflet in 6 cases. Ring annuloplasty was performed in 21 cases. Postoperative echocardiographic examination revealed no regurgitation in 41 patients, mild MR in 10, and moderate MR in 3. One patient died of arrhythmia early postoperatively. Another patient had cerebral infarction 10 months after the operation. No other complication or no late death was experienced.
  
  
  CONCLUSIONS
  Early and late results of mitral valve repair for mitral regurgitation was satisfactory. Better long-term results will be expected by the improvement of surgical technique.
