Abstract

We present a case of 58-year-old (tamale with dilated cardiomyopathy(DCMP) in whom we performed left ventricular(LV) remodeling surgery(Batista operation) to reduce the left ventricle diameter and improve left ventricular unction. The patient was admitted September 1996 with heart failure NYHA class IV. There was severe orthopnea and peripheral edema. 2-D echocardiography(Echo) showed DCMP with the ejection fraction(EF) I5%, LV end diastolic dimension(LVEDD) 80mm, mitral regurgitation(MR) grade IV, tricuspid regurgitation ('m) grade ll. Preoperative cardiac output(CO) was 1.5/L/min and cardiac index(Cl) was 1.0 L/min/m2. We proceeded with LV remodeling surgery by resection a part of LV lateral wall between both papillary muscle, from the mitral annulus to the LV apex. Size of resected LV wall was 90 $\times$ 100 $\times$ 15 mm. At the mean time, mitral valve and tricuspid valve were repaired. Postoperative 2-D Echo showed the EF 37%, LVEDD 50 mna, trivial MR, no TR. CO was 3.SL/min and Cl was 2.3 L/min/m2. Her fuctional NYHA class was 1.

저자들은 말기 확장성 심부전을 앓아온 58세의 여자환자에게 좌심실 내경을 줄여주는 좌심실개조수술을 시행하여 좌심실기능의 향상을 보았기에 증례보고를 하고자 한다. 본 환자는 1996년 9월에 심부전으로 인한 호흡곤란(NYHA 기능 4도)과 사지부종을 주소로 입원하였다. 입원시 심초음파검사상 좌심실 구축률 15%, 좌 심실 말기이완기 내경이 80mm, 승모판 폐쇄부전 4도, 삼첨판 폐쇄부전 2도였고 심박출량이 1.5L/min였고 심 박출계수는 1.0 L/min/m2 있단 이 환자에게 전방유두근과 후방유두근 사이의 좌심실 측벽을 절제하고 승모 판과 삼첨판 성형술을 실시하는 좌심실개조수술을 시행하였다. 술후 심초음파검사와 혈역학적 평가결과, 좌 심실 구축력 35%, 좌심실 말기이완기내경 50m였고, 승모판 기능 및 삼첨판 기능은 완벽하였다. 심박출량은 2.3L/ms 였고 심박출계수는 2.3umi m2였고 환자의 mID기능은 1도였다.
