Aim To analyze the correspondence of the 17 left ventricular myocardial segments with each coronary artery by using late gadolinium contrast enhanced cardiovascular magnetic resonance (CMR) imaging. Material and methods A total number of 58 patients with known or suspected ischemic heart disease were enrolled in this study. Those patients were scheduled for CMR and conventional coronary angiography. The correspondence between the coronary artery distribution and the supplied myocardium was assessed according to the 17-segment model. Results The segments 1, 2, 3, 7, 8, 13, 14 and 17 were totally specific for LAD, segments 6 and 12 were totally specific for LCX, and segment 10 was specific for RCA. There was overlap between LAD and RCA for segments 9 and 15. There was overlap between LCX and RCA for segments 4, 5 and 11. The segment 16 was shared by the all territories (LAD, LCX and RCA) with slight LCX predominance. Conclusions Our study concluded that the LAD territory on CMR bases is larger than the American Heart Association (AHA) proposed 17-segment model. [ABSTRACT FROM AUTHOR] |
