Design outcomes

Primary

MeasureTime frame
The normal left main coronary artery (LMCA) in Thai population The dimensions were preformed at two points: the proximal is the origin of LMCA from aorta and the distal is before taking its branches. The length was measured in long axis before taking branches. The dimensions of LMCA were performed with inner-to-inner line in plane of truly perpendicular cross-sectional MDCT during the end-diastolic phase. The length was measured in the long axis.

Secondary

MeasureTime frame
The relative of primary outcomes - The relative of primary outcomes with pateint characteristics and the other findings of cross-sectional MDCT reconstruction images.
