Mid-term Resuits of Mitral Valve Repair in Mitral Regurgitation

Between January 1992 and February 1995, 36 patients with mitral regurgitation were treated by a mitral repair. There were nineteen men and seventeen women whose mean age was 41.8 years, ranged from 10 to 71. Seventeenth patients had dystrophic change of mitral valve, twelve patients had rheumatic change of mitral valve, second patients had infective change of mitral valve and another fifth patients had functional change of mitral valve. Operation procedures were suture annuloplasty(35 cases), resection of leaflet(25 cases), chordae shortening(9 cases) and commisurotomy(1 cases). These procedures were combined in most patients. Two third of the patients were in New York Heart Association class III or IV and fifth of the patients were in mitral regurgitation grade III or IV by doppler echocardiogram. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data and functional class. Intraoperative TEE had been used in all most patients after weaning of bypass. Is there remained MR more than grade 2, the valve was re-repaired of replacement. There were no operative death. The late mortality was 5.5% and cause of death was congestive heart failure. Patients have been followed up from 3 to 40 months, mean 15. Second patients underwant reoperation due to recurred mitral regurgitation, 4 and 19 days after the operation. During reoperation, we found that the repair suture was disrupted in both patients. This expierence demonstrated that intraoperative TEE is accurate and predictable and excellent immediate and mid-term results have been achieved by mitral valve repair.ope
