      5‐Year clinical follow‐up of the COBRA (complex coronary bifurcation lesions: Randomized comparison of a strategy using a dedicated self‐expanding biolimus A9‐eluting stent vs. a culotte strategy using everolimus‐eluting stents) study
      Objectives We evaluated healing responses with optical coherence tomography, and long‐term clinical outcomes after treatment with a dedicated stent versus a conventional culotte technique. Background Dedicated bifurcation stents have been proposed as an alternative treatment for coronary bifurcation lesions. The long‐term performance of dedicated stents versus conventional dual‐stent techniques for the treatment of complex coronary bifurcation lesions is unknown.

      Optical Coherence Tomography Findings in Patients with Coronary Stent Thrombosis: A Report of the PREvention of Late Stent Thrombosis by an Interdisciplinary Global European Effort (PRESTIGE) Consortium
      Background Stent thrombosis (ST) is a serious complication following coronary stenting. Intravascular optical coherence tomography (OCT) may provide insights into mechanistic processes leading to ST. We performed a prospective, multicenter study to evaluate OCT findings in patients with ST. Methods Consecutive patients presenting with ST were prospectively enrolled in a registry using a centralized telephone registration system. After angiographic confirmation of ST, OCT imaging of the culprit vessel was performed ...

      Complex bifurcation lesions: Randomized comparison of a fully bioresorbable modified t stenting strategy versus bifurcation reconstruction with a dedicated self-expanding stent in combination with bioresorbable scaffolds, an OCT study: Rationale and desig
      Objective There is an ongoing controversy regarding the efficacy and safety of different percutaneous stenting techniques for coronary bifurcation lesions needing 1 stent. The promise of safe vessel restoration with bioresorbable scaffolds (BRS) may not be transferable to complex double BRS bifurcation techniques, and permanent metallic scaffolding of the bifurcation core may be needed. We identified modified-T stenting as the most promising fully bioresorbable 2-stent strategy in a preclinical setting ...

      Automated detection and quantification of clusters of malapposed and uncovered intracoronary stent struts assessed with optical coherence tomography
      To date, accurate quantification and localization of malapposed and uncovered struts needs manual and time consuming analysis of large datasets. To develop an algorithm for automated detection and quantification of clusters of malapposed and uncovered struts in optical coherence tomography (OCT) pullbacks, including comprehensive information about their three-dimensional spatial distribution. 64 lesions in 64 patients treated with drug-eluting stent underwent assessment with OCT immediately after implantation and at 9-month follow-up ...
