Abstract

Dual left anterior descending artery (LAD) is a rare congenital coronary artery anomaly with a prevalence of approximately 1% in the general population. To date, 10 types of dual LAD artery anomalies have been reported. Among these, type 4 is one of the rarest. Knowledge and recognition of the dual LAD artery are important for correct diagnosis and planning of coronary bypass surgery and percutaneous coronary intervention. We report a case of a 59-year-old male with type 4 dual LAD artery who presented with dyspepsia and sweating for several months and had approximately 50%-70% stenosis in a major diagonal branch off the short LAD artery.

이중 좌전하행 관상 동맥은 일반 인구에서 약 1%의 유병률을 보이는 드문 선천성 기형이다. 지금까지 이중 좌전하행 관상동맥 기형은 10가지 유형으로 보고되었다. 그중 제4형 이중 좌전하행 관상동맥은 가장 희귀한 유형 중 하나이다. 이중 좌전하행 관상동맥에 대한 지식과 인식은 정확한 진단과 관상동맥 우회 수술 및 경피적 관상동맥 중재술을 계획하는 데 중요하다. 저자들은 수개월 동안 소화불량과 발한을 주소로 내원하였고 짧은 좌전하행 관상동맥의 주요 대각분지에 약 50%-70% 협착이 있었던, 제4형 이중 좌전하행 관상동맥 기형을 가진 59세 남성의 증례를 보고하고자 한다.
