Abstract

|
|
|
Dual left anterior interventricular coronary artery (also called left anterior descending artery, hereafter referred as LAD) is a rare congenital coronary artery anomaly. Notably, type IV dual LAD has never been reported in Koreans. During a routine dissection, a new variant of type IV dual LAD was found in a 57-year-old Korean male cadaver, whose cause of death was unknown. One LAD originated from the right coronary artery, coursed through the anterior interventricular sulcus, but did not reach the apex cordis. The other LAD arose from the left coronary artery, never entered the anterior interventricular sulcus through its course, but reached the apex cordis, where it met the posterior interventricular branch of the right coronary artery. This is the first report on a new variant of type IV dual LAD in Koreans, which is of clinical importance during procedures containing the coronary artery.
