title: [Evaluation for mitral valvuloplasty using rasping procedure].
abstract: From April 1992 through July 1994, 7 patients underwent mitral valvuloplasty using rasping procedure in conjunction with open mitral commissurotomy. All patients had satisfactory postoperative results without the complications such as restenosis, regurgitation, infection. However, thromboembolism was observed in 1 patient at the postoperative 6 months. And no reoperation for repaired mitral valve was observed. Transvalvular pressure gradient significantly decreased from 14.3 +/- 8.5 mmHg to 4.7 +/- 1.6 mmHg after operation. Mitral valve areas significantly increased from 1.01 +/- 0.31 cm2 to 1.78 +/- 0.41 cm2 after operation. As compared with preoperative value of 0.32 +/- 0.02, postoperative left ventricular fractional shortening (LVFS) significantly improved to 0.40 +/- 0.03. The advantages of this method is considered to be equable and safe débridement, and no anticoagulation at late period. Mitral valvuloplasty using rasping procedure, except for transmural calcified lesions, is useful and effective method. And excellent postoperative long-term results could be expected.
