      In-Stent Restenosis Lesion Morphology Related to Repeat Stenting Underexpansion as Evaluated by Optical Coherence Tomography

      Aims: To use optical coherence tomography (OCT) to predict newly implanted stent expansion for treatment of in-stent restenosis (ISR). Methods and results: With OCT-guidance, 143 ISR lesions were treated with a new stent. Stent underexpansion was defined as minimum stent area (MSA) <4.5mm 2 and MSA/average of reference lumen area <70%. New stent underexpansion was found in 33 lesions (23%), had a smaller old stent MSA (4.13 [3.32-4.62] versus 5.18 [4.01-6.38] mm 2 , p=0.001), and had a higher prevalence of multiple old stent layers (51.5% versus 10.9%, p ...

    2. Effect of orbital atherectomy in calcified coronary artery lesions as assessed by optical coherence tomography

      Effect of orbital atherectomy in calcified coronary artery lesions as assessed by optical coherence tomography

      Objectives We sought to assess plaque modification and stent expansion following orbital atherectomy (OA) for calcified lesions using optical coherence tomography (OCT). Background The efficacy of OA for treating calcified lesions is not well studied, especially using intravascular imaging in vivo. Methods OCT was performed preprocedure, post‐OA, and post‐stent ( n  = 58). Calcium modification after OA was defined as a round, concave, polished calcium surface. Calcium fracture was complete discontinuity of calcium. Results Comparing pre‐ vs post‐OA OCT ( n  = 29), calcium area was significantly decreased post‐OA (from 3.4 mm 2 [2.4–4.7] to 2 ...
