Length of Left Anterior Descending (LAD) Coronary Artery in Relation to Right & Left Dominancy: A Retrospective Computed Tomographic (CT) Coronary Angiographic Study
Journal Title: The Egyptian Journal of Hospital Medicine - Year 2018, Vol 71, Issue 4
Abstract
<span>Background: </span><span>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.<br /> </span><span>Objective: </span><span>to estimate the length of LAD artery and its possible relationship with the coronary arterial dominance pattern.<br /> </span><span>Patients and Methods: </span><span>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<br /> </span><span>Results: </span><span>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.<br /> </span><span>Conclusion: </span><span>length of LAD artery appeared to be dependent on the dominance pattern and it was taller in left coronary dominant pattern.<br /> </span>
