Abstract

Heart transplantation was planned for a 10-year old boy who had dilated cardiomyopathy with severe congestive heart failure and had been on dopamine for 1month. However, partial left ventriculectomy and mitral annuloplasty were performed instead, because there was no donor heart of the adequate size and the symptoms were aggravated. The clinical symptoms were markedly improved after the surgery. Comparing the postoperative echocardiographic results with the preoperative results, there were remarkable changes in the left ventricular ejection fraction(preoperative LV EF 17% to postoperative 3 months 29%, 6 months 35%, 1 year 36%) and the left ventricular end-diastolic dimension(preoperative 72 mm to postoperative 3 months 59 mm, 6 months 61 mm, 1 year 61 mm). Partial left ventriculectomy and mitral annuloplasty reduced the cardiac loading in the dilated cardiomyopathy. Partial left ventriculectomy and mitral annuloplasty may be considered as one of the alternative surgical metho s to carry over until a heart transplantation can be performed, especially for children.

심한 울혈성 심부전으로 Dopamine을 1개월간 사용해온 10세의 확장성 심근증 환아에서 심장 이식을 시행하려 하였으나, 적절한 크기의 공여 심장이 없었고, 환아의 증상이 악화되어 부분 심실 절제술과 승모판 성형술을 시행하였다. 수술후 환아의 임상 증상은 현저히 호전되었고 수술전과 수술후 3개월, 6개월 1년째의 심장 초음파 검사 소견을 비교하여 추적 관찰한 결과, 좌심실의 심박출 계수는 수술전 17 %에서 수술후 각각 29%, 35%, 36%로 개선되었고 좌심실 확장기말 직경은 수술전 72 mm에서 수술후 각각 59 mm, 61 mm, 61 mm로 변화를 보였다. 부분 좌심실 절제술과 승모판 성형술의 동반 시행은 심장 이식의 기회가 상대적으로 적은 소아의 확장성 심근증에 있어 심장의 부하를 감소시켜 증상 완화를 시킬 수 있는 외과적 방법으로 심장 이식을 시행할 때까지 유지시켜주는 고식적 가치가 크며 아울러 장기적 추적 관찰이 필요하다고 사료 된다.
