| Popis: | Purpose Coronary arterial lesion assessment in children can be difficult, depending on the coronary dominance pattern. Although it is easier to determine coronary dominance with echocardiography in children than in adults, it is still difficult. This study aimed to examine the coronary dominance pattern according to the objective coronary artery (CA) indices. Methods The CA diameter, aortic valve annulus, and abdominal aorta of 69 children without any cardiovascular disease were measured with cross-sectional echocardiography at Chungnam National University Hospital. To evaluate the coronary dominance pattern, echocardiography was primarily used; additionally, coronary computed tomographic angiography or coronary angiography (CAG). Coronary dominance was determined according to the status of the CA that gives rise to the posterior descending artery. Results The mean age was 4.02±2.78 years, and the mean body surface area (BSA) was 0.70±0.22 m2 . Right dominance was present in 78% and left in 22% of the subjects. In those with left dominance, the CA to aortic valve annulus diameter ratio was 0.125±0.021 in the right coronary artery (RCA) and 0.255±0.032 in the left coronary artery (LCA). In those with right dominance, the corresponding ratio was 0.168±0.028 in the RCA and 0.216±0.030 in the LCA (P |
