Abstract

Double-outlet left ventricle(DOLV) is a rare congenital cardiac malformation, defined as the origin of both the aorta and the pulmonary artery being entirely or predominantly above the morphologically left ventricle, which is difficult to diagnose accurately. A 3-year old male was admitted for cyanosis and dyspnea. At the age of 2 months, he had undergone pulmonary artery banding and coarctoplasty. He was diagnosed as DOLV with subaortic ventricular septal defect(VSD). Biventricular repair was achieved by patch closure of VSD, primary closure of PFO, and pulmonary trunk translocation from left ventricle to right ventricle. The advantages of this procedure using native tissue for right ventricular outflow tract reconstruction are growth potential and preserved valve function, which contribute to a decreased likelihood of reoperation related to the right ventricular dysfunction related to pulmonary insufficiency.

양대혈관 좌심실기시는 양대혈관이 좌심실에서 기시하는 드문 선천성 심장기형으로 정확하게 진단하기가 어렵다. 환아는 생 후 2개월에 대동맥축착교정술 및 폐동맥교약술을 받았던 3세된 남아로 대동맥하 심실중격결손, 단일관상동맥을 동반한 양대혈관 좌심실기시로 진단되어 심실중격결손의 첩포봉합, 난원공개존의 봉합 폐동맥 교약부 절제, 그리고 폐동맥간을 좌심실에서 분리 후 우심실로 전위시켜 우심실 유출로 재건술을 받았다. 본 술식은 술 후 좋은 혈역학적 특성을 보였고, 자가조직을 사용함으로써 전위된 폐동맥의 성장잠재성과 판막 기능의 보존으로 술 후 폐동맥 폐쇄부전과 관련된 우심실기능부전의 가능성이 줄어드는 장점이 예상되므로 문헌 고찰과 함께 보고한다.
