Abstract

Background: the LAD artery supplies blood to a large part of the myocardium. However, the amount of myocardium supplied varies depending on the length of LAD artery and as a result; occlusion at different portion may influence perfusion of different part of myocardial.
Objective: to estimate the length of LAD artery and its possible relationship with the coronary arterial dominance pattern.
Patients and Methods: in this study we retrospectively compared 50 coronary CT angiograms of patients with left coronary dominance with 50 coronary CT angiograms of patients with right coronary dominance
Results: it revealed that there was a significant relationship between the length of LAD artery and the pattern of dominancy since the P- Value appeared to be < 0.001.
Conclusion: length of LAD artery appeared to be dependent on the dominance pattern and it was taller in left coronary dominant pattern.
