The LM has an irregular 30% distal stenosis, followed by an 80% ostial LAD stenosis, and total occlusion of the LAD proximally with TIMI grade 1 flow in the distal vessel. The LCX demonstrates an ostial 80% stenosis prior to the bifurcation of a large OM artery. A large Diagonal artery has subtotal occlusion proximally.
