What is the prevalence and characteristics of dual left anterior descending artery in adults undergoing coronary angiography?
Dual LAD is a rare coronary anomaly present in 0.68% of adults undergoing coronary angiography, with type I being the most common variant.
Raises awareness of dual LAD variants during angiography; leaves open their prognostic and management implications.
Aim: To determine the prevalence and characteristics of dual left anterior descending artery (LAD) in adults undergoing catheter coronary angiography. Materials & methods: We identified cases with dual LAD by retrospectively analyzing 3233 angiograms done from January 2017 to June 2019. Results: Dual LAD was seen in 22 patients (0.68%). We identified type I dual LAD in 14 cases, type II in 7 cases and type III in 1 case. Significant stenosis was seen in proximal part of long LAD in 12 cases, in LAD proper in 7 cases and in proximal part of short LAD in 4 cases. Conclusion: Dual LAD is a rare anomaly. Its sound knowledge is essential for proper management of patients with coronary artery disease.
