ABSTRACT
In the preoperative evaluation before coronary artery bypass surgery, review of the coronary arteriogram is the most important step. Expected "normal" lumen diameter at a given coronary anatomic location is a basis for quantative estimation of coronary disease severity that could be more useful than the traditional "percent stenosis". The distribution and number of major coronary artery branches are determinants of number of bypass grafts needed. We reviewed the coronary artery anatomy in 174 adult patients who revealed no coronary pathology in angiographic studies done from September 1994 to June 1996. Quantative analysis was done in all cases by a single person using a Computerized System (Arripro 35(r)). The results were follows; 1) The mean diametre of left main coronary artery was 4.45 mm (range 2.74~6.72). The pattern of branching was bifurcation in 67.24%, trifurcation in 28.74% and quadrifurcation in 4.02% of the patients. 2) The mean diametre of left anterior descending artery was 3.17 mm (range 2.10~5.85), 2.79 (range 1.55~5.59) and 2.17 mm (range 1.37~3.81) in the proximal, mid, and the distal portions, respectively. The number of diagonal branches of left anterior artery was from one to four (mode=2). 3) The mean diametre of proximal and distal left circumflex artery were 3.17mm (range 1.74~4.89) and 2.19 mm (range 1.21~4.46). The number of obtuse marginal branches of left circumflex artery is from one to six (mode 2). 4) The mean diametre of proximal and distal right coronary artery, the posterior descending artery and the largest posterolateral branch were mean 3.51 mm (range 2.07~5.67), 2.09 mm (range 1.42~3.60), 2.09 mm (range 1.02~3.60) and 2.30 mm (range 1.39~4.39). 5) The right coronary artery dominant was 163 cases (93.68%) of the total 174 cases. 6) The large significant acute marginal artery was visualized in more than half of the people.
