    1. Optical Coherence Tomography to Guide Percutaneous Coronary Intervention of the Left Main Coronary Artery: the LEMON study

      Optical Coherence Tomography to Guide Percutaneous Coronary Intervention of the Left Main Coronary Artery: the LEMON study

      Aims: IVUS is currently recommended by international guidelines to guide left main stem (LMS) PCI. Although OCT resolution outmatches IVUS, this tool is not yet recommended in LMS angioplasty due to the absence of data. This pilot study aimed to analyze the feasibility, safety and impact of OCT-guided LMS PCI. Methods and results: This prospective, multicenter trial investigated whether patients might benefit from OCT-guided PCI for mid/distal LMS according to a pre-specified protocol. The primary endpoint was procedural success defined as follows: residual angiographic stenosis <50% + TIMI 3 flow in all branches + adequate OCT stent expansion (LEMON criteria ...

    2. Characteristics of stent thrombosis in bifurcation lesions analyzed by optical coherence tomography

      Characteristics of stent thrombosis in bifurcation lesions analyzed by optical coherence tomography

      Aims: This work aimed to investigate a cohort of patients presenting with stent thrombosis (ST) explored by optical coherence tomography (OCT) to identify the underlying mechanical abnormalities in case of bifurcation lesions. Methods and results: The PESTO study was a prospective national registry involving 29 French catheterization facilities. Patients with acute coronary syndromes were prospectively screened for presence of definite ST and analyzed by OCT after culprit lesion reopening.The cohort involved n=120 subjects, including n=21 patients (17.5% of the global PESTO group; median age: 62.6 y; 76% male) with bifurcation lesions. The clinical presentation was ...

    3. Optical coherence tomography (OCT) of overlapping bioresorbable scaffolds: from benchwork to clinical application

      Optical coherence tomography (OCT) of overlapping bioresorbable scaffolds: from benchwork to clinical application

      Fully bioresorbable everolimus-eluting vascular scaffolds (BVS: Abbott Vascular) are a novel approach to treating coronary lesions. The ABSORB cohort A and cohort B trials investigated the implantation of 3 mm BVS, up to a maximum length of 18 mm, in simple lesions only, The implantation of overlapping BVS in longer lesions has not previously been reported.
