Abstract

We evaluated the impact of different intravascular ultrasound (IVUS) criteria on 6-month angiographic restenosis in 511 patients with 560 lesions. Seven IVUS criteria were evaluated in this study; stent area at lesion segment 1) ≥ 100% of distal reference lumen area, 2) ≥ 90% of distal reference lumen area, 3) ≥ 80% of average reference lumen area, 4) ≥ 90% of average reference lumen area, 5) ≥ 55% of average reference vessel area, 6) ≥ 7 mm2, and 7) ≥ 9 mm2. Using the relative measurement (criteria 1-5), the angiographic restenosis rate was not statistically different. However, absolute measurement of stent area ≥ 7 or 9 mm2 (criteria 6 and 7) were associated with significantly lower restenosis rate (14.8% vs. 30.9%, P = 0.001, and 13.5% vs. 24.6%, P = 0.006, respectively). In conclusions, using the relative measurement of IVUS criteria, the occurrence of angiographic restenosis might not be predicted. The absolute measurement of IVUS stent area was the predictor of angiographic restenosis.
