Fig. 1From: Positron emission tomography rubidium-82 myocardial perfusion imaging in diagnosing uncommon paediatric acute coronary syndrome: a case reportCCTA of left anterior descending (LAD) coronary artery. The LAD coronary artery is a normal-size vessel, which reaches the apex. There is no luminal stenosis at the proximal or mid segments of the LAD coronary artery. It gives rise to a moderately sized diagonal branch with moderate to severe (50–80%) stenosis at the mid segment. The distal vessel is normal and ends at the apexBack to article page
