An intravascular ultrasound appraisal of atherosclerotic plaque distribution in diseased coronary arteries

Intravascular ultrasound data indicated a proximal-to-distal LAD plaque gradient; significant disease was uncommon in the distal LAD. Conversely, the proximal-to-distal RCA plaque gradient was less distinct than the LAD, although disease in the PDA was still reduced compared with proximal segments.
