Type IV dual left anterior descending (LAD) coronary artery system.
Pak Armed Forces Med J Jan ;61(2):308-10.

The incidence of dual left anterior descending coronary artery (LAD) in normal hearts has been reported to range from 0.13% to 1%4. However, inadvertent incorrect placement of an arteriotomy due to nonrecognition of the anomaly, difficulties in identification and grafting of a short LAD proper and the intramyocardial course of the aberrant vessel are of concern during surgical revascularization. We report a case of dual LAD where Angiographic and MSCT findings were consistent with type IV dual LAD system.
