Significance of Dual Left Anterior Descending Coronary Artery in Interventional Cardiology

Abstract

The variants of the left anterior descending (LAD) coronary artery are important in interpretation of coronary angiograms and in interventional procedures. The authors present a patient who had percutaneous transluminal coronary angioplasty and stent implantation to a presumed proximal LAD without the realization that dual LAd was present because of the total occlusion of the long LAD.
