Patient Data

Age: 50 years
Gender: Male

CORONARY ANATOMY: The coronary arteries arise in a normal position. Co-dominant circulation: the right coronary supplies the posterior descending artery, the circumflex supplies a posterior left ventricular branch.

 CORONARY CT ANGIOGRAM:

Left main: the left main coronary artery bifurcates into the LAD and CX; atherosclerotic plaque with minimal stenosis (1-24%)

Left anterior descending: atherosclerotic plaque with occlusion of D1 (100%), severe stenosis (70-99%) of the midsegment, and moderate stenosis (50-69%) of the distal segment

Left circumflex: plaque and/or stenosis: atherosclerotic plaque with mild stenosis (25-49%)

Ramus intermedius branch:  occluded.

Right coronary artery: atherosclerotic plaque which is occlusive (100% stenosis) along the proximal segment, with distal reconstitution

Case Discussion

A nice example of multi-vessel coronary artery disease.
