Dual LAD – Contemporary Review

Abstract

Dual LAD had been reported to occur with an incidence of 1% by Morettin [1] as well as Spindola-Franco et al. [2]. There is a lot of case reports on dual left anterior descending (LAD) coronary artery. The first description of a type IV dual LAD distribution was made in 1939, by Waterston et al. [3] in the case of Sir James Mackenzie, who had this type of distribution. By now six types of this anomaly have been described in the literature. But there is no any review article describing this anomaly in general, so we decided to write one.
