Abstract
Dual left anterior descending artery (LAD) is a rare coronary anomaly that is important to recognize at coronary imaging as it may influence reperfusion strategies. Four types of dual LAD are described by the traditional literature. We present a novel case of dual LAD with coronary computed tomographic angiographic correlation that does not fit into this classification system. Rather, our case supports the recently proposed notion of adding a fifth variant to the traditional dual LAD classification system.
Highlights
Dual left anterior descending artery (LAD) is an extremely rare coronary anomaly traditionally classified into one of four types
The septal course of the aberrant long LAD presumably mitigates against the risk of sudden cardiac death associated with a malignant interarterial LAD [3]
Dual LAD is a rare type of coronary artery anomaly that is important to recognize and characterize as it may critically influence surgical or angiographic reperfusion strategies [1, 4]
Summary
Dual left anterior descending artery (LAD) is an extremely rare coronary anomaly traditionally classified into one of four types. Recognition at coronary imaging is critical as both surgical and percutaneous reperfusion strategies may be altered by its presence [1]
