Abstract

Between January 1992 and February 1995, 36 patients with mitral regurgitation were treated by a mitral repair There wert 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 proced res were suture annuloplasty (35 cases), resection of leaflet (25 cases), chordal 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 four 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. If there remained MR more than grade 2, the valve was re-repaired or 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. Th s expierence demonstrated that intraoperative TEE is accurate and predictable and excellent immediate and mid-term results have been achieved by mitral valve repair.

연세대학교 의과대학 심혈관 센터 심혈관외과에서는 1992년 1월부터 1995년 2월까지 3년 2개월 동안 36명의 승모판막 폐쇄부전증 환자에게 승모판막 재건술을 시행하였다. 평균 연령은 41.8세였고 연령분포는 10세에서 71세였으며 환자의 성별 분포는 남자 19명 여자 17명이었다. 판막 병변의 원인은 이형성이 17례, 류마티스성이 12례, 심내막염이 2례, 기타 기능적 변화가 5례였다. 수술 수기는 봉합성형술 35례, 첨판의 절제 25례, 건삭의 단축 9례, 교련절개술 1례에서 시행되었다. 수술 수기는 대부분의 경우에서 위의 방법을 복합적으로 시술하였다. 수술 당시의 환자의 임상소견은 NYHA 기능적 분류 3 또는 4등급이 67%였고, 도플러 심초음파 검사상 3또는 4등급이 83%로 대부분 중등도 이상의 질환 양터를 보였다. 승모판 재건술후 혈류역학적 수치, 심초음파 소견, 환자의 임상 상태등은 전반적으로 호전되었다. 모든 환자에서 수술대 에서 경식도 심초음파 검사를 인공 심폐기로부터 이탈 직후 실시하였고, 검사상 승모판막의 폐쇄부전의 정도가 2등급 이상일때는 재수술을 즉시 시행하였다. 술후 평균 외래 추적 관찰기간은 15개월(3~40개월)이다. 수술\ulcorner 병원 사망은 없었고 외래 추적 관찰중 2명의 사망 환자가 발생하여 사망율은 5.5%였으며 사망의 원인은 심부전이었다 2명의 환자에서 승모판막 폐쇄 부전의 재발로 술후 4일과 19일째 승모판막 치환술로 재수술 받았다. 재수술 받게된 원인은 봉합사의 파열이었다. 이상에서 보면 수술 직후에 실시한 경식도 심초음파 검사는 승모판막의 재건술시 수술의 결과를 판정하는데 매우 유용하고 정확한 진단 방법으로 사용이 권장되어야 한다고 생각되며, 승모판막의 재건술은 승모판막 폐쇄부전증 환자에게 적용할 수 있는 좋은 수술 방법이고, 본원에서는 만족할만한 결과를 얻었다.
