A 57-year-old woman presented with typical angina. Thallium stress testing showed anteroapical reversible ischemia. Coronary angiography demonstrated only a mild stenosis (open black arrow) of the mid-left anterior descending coronary artery (LAD). She was treated medically and did not improve. Intravascular ultrasound examination was used to further evaluate this ambiguous coronary stenosis.

Angiogram of left coronary system and six ultrasound images acquired at various locations within LAD, shown by white arrows. A 7F diagnostic catheter (solid short white arrow) provides a reference diameter of 2.2 mm. A, Image from mid-left main coronary artery. Vessel lumen is compromised by a crescentic fibrous plaque extending from 7 o'clock to 2 o'clock position. B, Bifurcation of left main artery into LAD and left circumflex (LCX). C, Proximal reference vessel. Lumen diameter is 3x3 mm. Black hash mark at 3 o'clock position shows a 1-mm calibration. D, Entry into this indeterminate lesion has only a small rim of echolucent lumen around ultrasound catheter. A near circumferential plaque fills rest of lumen. E, Tightest point seen by intravascular ultrasound demonstrates white echodense plaque surrounding ultrasound catheter, almost obliterating vessel lumen. F, Distal reference artery beyond stenosis shows a widely patent vessel with minimal atherosclerosis.
