      A prospective, single‐center, randomized study to assess whether automated coregistration of optical coherence tomography with angiography can reduce geographic miss

      Objective We sought to evaluate whether automated coregistration of optical coherence tomography (OCT) with angiography reduces geographic miss (GM) during coronary stenting. Background Previous intravascular ultrasound or OCT studies have showed that residual disease at the stent edge or stent edge dissection was associated with stent thrombosis or edge restenosis. This has been termed GM. Methods Two hundred de novo coronary lesions were randomized in a 1:1 ratio to OCT‐guided percutaneous coronary intervention (PCI) with versus without automated coregistration of OCT with angiography. GM, the primary endpoint, was defined as angiographic ≥type B dissection or diameter stenosis >50 ...

      The Effectiveness of Excimer Laser Angioplasty to Treat Coronary In-Stent Restenosis With Peri-stent Calcium as Assessed by Optical Coherence Tomography

      Aims: We evaluated the effectiveness of excimer laser coronary angioplasty (ELCA) to treat in-stent restenosis (ISR) due to peri-stent calcium-related stent under-expansion as assessed by optical coherence tomography (OCT). Methods and results: We studied 81 patients (81 lesions with ISR, stent under-expansion, and peri-stent calcium >90°) who underwent OCT imaging both pre- and post-percutaneous coronary intervention and compared lesions treated with ELCA (n=23) vs without ELCA (n=58). ELCA use was associated with more calcium fracture (ELCA: 61%, non-ELCA: 12%, p<0.01), . larger final minimum lumen area (ELCA: 4.76 mm2 [3.25, 5.57], non-ELCA: 3.46 ...
