Bench testing and coronary artery bifurcations: A consensus document from the European Bifurcation Club

This is a consensus document from the European Bifurcation Club concerning bench testing in coronary artery bifurcations. It is intended to provide guidelines for bench assessment of stents and other strategies in coronary bifurcation treatment where the United States Food and Drug Administration (FDA) or International Organization for Standardization (ISO) guidelines are limited or absent. These recommendations provide guidelines rather than a step-by-step manual. We provide data on the anatomy of bifurcations and elastic response of coronary arteries to aid model construction. We discuss testing apparatus, bench testing endpoints and bifurcation nomenclature.

Coronary artery bifurcation haemodynamics - comparison between phase contrast MRI and computational fluid dynamics

Background Coronary atherosclerosis is common at vessel bifurcations. A quantitative approach to measuring blood velocity, vorticity and more complex flow features at bifurcations would enhance the understanding of the mechanisms of atheroma development, and potentially predict vessels at highest risk. The aim of this work was to validate 4D phase contrast (PC) magnetic resonance imaging flow measurements using a simplified arterial model of the left main coronary bifurcation against computational fluid dynamic (CFD) modelling. Methods

Coronary balloon catheter tip damage. A bench study of a clinical problem

To confirm clinically that coronary balloon catheter tips may be damaged during bifurcation treatment with side‐branch access through the side of a stent. On the bench, we aimed to assess the susceptibility of different balloon designs to damage. We compared catheter tip widths. We tested whether balloon tip flaring can cause stent distortion.

The “OneShot” Irrigated Balloon-Mounted Spiral Electrode Renal Denervation Device

The OneShot Renal Ablation System (Covidien, Campbell, CA, United States of America) is an irrigated RF balloon designed to deliver electrical current alternating at RF to achieve denervation using a single 2-min ablation to each renal artery. The total duration of energy application is shortened to typically 4 min hence the procedure can be shorter and the duration of pain limited [8,9]. The spiral electrode may ensure more predictable ablation than a point by point approach.

TCT-17 Prospective, Multi-Center Evaluation of the DESolve Novolimus-Eluting Bioresorbable Coronary Scaffold: Imaging Outcomes and 3-Year Clinical and Imaging Results

The DESolve® Novolimus Eluting Bioresorbable Coronary Scaffold System (NEBCSS) is a drug-eluting bioresorbable scaffold combining a PLLA-based scaffold coated with a biodegradable polylactide-based polymer and Novolimus, a macrocyclic lactone mTOR inhibitor. The DESolve NX study is a prospective,
