1. Moderate coronary artery calcification, with the patient nearly at 70th
percentile adjusted for age. 2. Accessory small LAD coronary artery arising
from the right coronary cusp, with an inter-arterial course and appearing
patent. 3. Mixed plaque formation in the mid left circumflex coronary
artery, producing mild to moderate-grade stenosis. Mild to moderate-grade
stenosis in proximal OM1, produced by calcified plaque. No significant stenosis
within the right coronary artery or the LAD.
Comment: An inter-arterial course of the LAD can be associated with ischaemia
and cardiac arrhythmias and sudden cardiac death and is classified as a
malignant coronary anomaly. There is a true LAD which supplies the major
distribution of the usual LAD territory, however the LV apex appears to be
supplied solely by the accessory LAD.
