Summary
A rare dual left anterior descending artery (LAD) anomaly presented significant proximal stenosis in both branches of a 75-year-old male. Both LAD branches were successfully revascularized with coronary artery bypass grafting.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Anatomical Variations
Background:
- Dual left anterior descending artery (LAD) is a rare coronary anomaly.
- Normally originated dual LAD is typically considered clinically insignificant.
Observation:
- A 75-year-old male presented with anginal symptoms.
- Coronary arteriography revealed a normally originated dual LAD with two branches of nearly equal caliber.
- Both LAD branches supplied the typical territory and exhibited significant proximal stenosis.
Findings:
- The dual LAD anomaly demonstrated symmetrical atherosclerotic involvement in the proximal segments of both branches.
- The condition was confirmed intraoperatively.
- The patient underwent successful coronary artery bypass grafting, revascularizing both LAD branches.
Implications:
- This case highlights that normally originated dual LAD can be clinically significant when affected by atherosclerosis.
- Symmetrical involvement of dual LAD branches presents unique challenges and considerations for surgical revascularization.
- This case underscores the importance of detailed coronary imaging in identifying and managing rare coronary anomalies.
