Insights
A rare dual left anterior descending (LAD) artery, a congenital coronary anomaly, was identified in a 44-year-old man experiencing exertional angina. This case highlights a rare variant potentially linked to cardiac events.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Vascular Anatomy
Background:
- Coronary artery anomalies are congenital variations in coronary artery anatomy.
- These anomalies are a significant cause of sudden cardiac death, particularly in young athletes.
- Dual left anterior descending (LAD) artery is an uncommon coronary anomaly.
Purpose of the Study:
- To report a rare case of type 4 dual LAD artery.
- To discuss the clinical presentation and diagnostic findings of this anomaly.
Main Methods:
- Case presentation of a 44-year-old male with exertional angina and ischemia.
- Diagnostic workup included coronary angiography and computed tomography (CT).
Main Results:
- Coronary angiography and CT revealed a type 4 dual LAD artery.
- This represents the rarest and most complex variant of dual LAD artery.
Conclusions:
- Dual LAD artery is a rare congenital coronary anomaly.
- Accurate diagnosis through imaging is crucial for understanding potential clinical implications.
Abstract:
Coronary artery anomalies are congenital changes in their origin, course, and/or structure. They are the second most frequent cause of sudden death in young athletes. Dual LAD artery is a rare coronary anomaly. We present the case of a 44-year-old man with recent onset exertional angina and documented ischemia whose coronary angiogram and computed tomography (CT) showed type 4 dual LAD artery, the rarest and most interesting variant.
