    1. Absorb vs. DESolve: an optical coherence tomography comparison of acute mechanical performances

      Absorb vs. DESolve: an optical coherence tomography comparison of acute mechanical performances

      Aims: The aim of the study was to compare retrospectively the acute mechanical performance of the Absorb vs. DESolve scaffolds in terms of appropriate deployment with OCT. Methods and results: Final post-deployment OCT pullbacks of consecutive patients treated with either Absorb or DESolve were reviewed. The following parameters were calculated and compared: mean and minimal lumen area (MLA), residual in-scaffold area stenosis (RAS), incomplete strut apposition (ISA), tissue prolapse area, eccentricity index, asymmetry index, strut fracture and edge dissection. A total of 72 patients were included. The Absorb group consisted of 35 patients treated with 63 Absorb scaffolds and was ...

    2. Bioresorbable vascular scaffold overlap evaluation with optical coherence tomography after implantation with or without enhanced stent visualization system (WOLFIE study): a two-centre prospective comparison

      Bioresorbable vascular scaffold overlap evaluation with optical coherence tomography after implantation with or without enhanced stent visualization system (WOLFIE study): a two-centre prospective comparison

      To assess if enhanced stent visualization (ESV)-guided implantation of overlapping bioresorbable vascular scaffold (BVS) is superior to angiography alone-guided implantation in the reduction of overlap length. WOLFIE is a two-centre prospective open study enrolling 30 patients treated with implantation of at least two overlapping BVS. In the first centre (London), BVS implantation was guided by conventional angiography, while in the second centre (Ferrara), an ESV system was systematically employed. The primary endpoint of the study was overlap length. Secondary endpoints were: stacked struts number, area, thickness, and amount of clusters. In the ESV-guided group, overlap length was significantly lower ...

    3. Optical Coherence Tomography Evaluation of Overlapping Everolimus-Eluting Bioresorbable Vascular Scaffolds implantation guided by Enhanced Stent Visualization System

      Optical Coherence Tomography Evaluation of Overlapping Everolimus-Eluting Bioresorbable Vascular Scaffolds implantation guided by Enhanced Stent Visualization System

      In a porcine model, implantation of overlapping everolimus-eluting bioresorbable vascular scaffolds (BVS, Abbott Vascular, Santa Clara, California) resulted in delayed struts coverage and higher neointimal response [1] that might lead to important clinical consequences (scaffold thrombosis; in-scaffold restenosis). According to this, any effort to minimize BVS overlap area and the number of overlapping struts is desirable. A bench testing in an in vitro phantom model has shown how to minimize BVS overlap utilizing the platinum markers located at each BVS edge, where the ideal overlap should be achieved when BVS edge markers positioned at 90 degrees to each other, causing ...

    4. ABSORB Biodegradable Stents Versus Second-Generation Metal Stents : A Comparison Study of 100 Complex Lesions Treated Under OCT Guidance

      ABSORB Biodegradable Stents Versus Second-Generation Metal Stents : A Comparison Study of 100 Complex Lesions Treated Under OCT Guidance

      Objectives The aim of this study was to compare the acute performance of the PLLA ABSORB bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) with second-generation metal drug-eluting stents (DES) in complex coronary artery lesions. Background Thick polymer-based BVS have different mechanical properties than thin second-generation DES. Data on the acute performance of BVS are limited to simple coronary lesions treated in trials with strict inclusion criteria. Methods Fifty complex coronary lesions (all type American College of Cardiology/American Heart Association B2-C) treated with a BVS undergoing a final optical coherence tomography (OCT) examination were compared with an equal ...

    5. Optical coherence tomography characteristics of in-stent restenosis are different between first and second generation drug eluting stents ☆

      Optical coherence tomography characteristics of in-stent restenosis are different between first and second generation drug eluting stents ☆

      Aims Characterization of neointimal tissue is essential to understand the pathophysiology of in-stent restenosis (ISR) after drug eluting stent (DES) implantation. Using optical coherence tomography (OCT), we compared the morphologic characteristics of ISR between first and second generation DES. Methods and Results OCT was performed in 66 DES-ISR, defined as > 50% angiographic diameter stenosis within the stented segment. Patients with ISR of first generation sirolimus-eluting stents (SES), paclitaxel eluting stents (PES) and second generation zotarolimus-eluting stents (ZES), everolimus-eluting stents (EES) and biolimus-eluting stents (BES) were enrolled. Quantitative and qualitative ISR tissue analysis was performed at 1-mm intervals along the entire ...
