Figure 2 Representative examples of coronary angiograms and intravascular ultrasound (IVUS) images are shown in a patient treated with combined low density lipoprotein-apheresis and cholesterol-lowering drugs for one year. In coronary angiograms (A and B in baseline and follow-up, respectively), the minimal lumen diameter (MLD) at the left anterior descending coronary artery (LAD) increased from 1.5 to 2.2 mm. Panels C and D show the same portion using IVUS imaging. The plaque area was decreased from 7.8 to 7.0 mm2, which was associated with an increase in the lumen area from 3.3 to 5.3 mm2. The vessel area also changed, from 11.1 to 12.3 mm2. The image in D2 is the second diagonal branch as the reference vessel.
