5-year followup of bioresorbable scaffolds in selected and better prepared lesions (ABSORB IV). Historically, when comparing previously used therapies, such as conventional balloon angioplasty (BA) against bare metal stent (BMS) and later against drug eluting stent (DES) implantation, we see significantly improved outcomes. These advances have shown reduced recoil and more effective restenosis inhibition, compared...

New SOLACI Event with BIOTRONIK to discuss current relevant topics on interventional cardiology. In this activity, we will be sharing, together with renowned Latin American specialists, information and perspectives on the following topic: “Paradigm shift with magnesium based bioresorbable technology. Innovation highlights on bioresorbable scaffolds”. Date: May 6, 2022, 07.30 PM (Argentina / Brasil Time;...
A new sirolimus-eluting bioresorbable scaffold with far thinner struts resulted non inferior to the Xience as to the end point of angiographic in-segment late loss (LL) powered for noninferiority testing. Even though this is a small study with angiographic end points, it might be the first step towards the return of bioresorbable scaffolds. Read also:...
A small number of highly selected patients presents good outcomes with new bioresorbable scaffold MeRes, but much more evidence is necessary to bring back the concept. The MeRes-1 study tested the newest generation of the Meril Life Sciences bioresorbable scaffold, a device featuring thinner struts compared with Absorb (from 150 µm in Absorb to only...
Previous studies have documented higher rates of adverse events with bioresorbable scaffolds (ABSORB) compared with metallic drug-eluting stents (DES). However, these studies included lesions smaller than recommended for these scaffolds and a suboptimal implantation technique. The ABSORB IV study, presented by Dr. Stone at TCT 2018 and published simultaneously in The Lancet, randomized patients to polymeric everolimus-eluting scaffold Absorb...
A year after the implantation of everolimus-eluting bioresorbable scaffold Absorb 1.1, optical coherence tomography (OCT) scans showed neointima formation covering plaque without significant luminal loss. At 5 years, the device is supposed to disappear completely, potentially thrombogenic plaque components are supposed to be covered by endothelium, and the vasomotor function is supposed to be recovered. However, there...
Courtesy of the SBHCI. The Absorb IV trial randomized 2604 patients in a 1:1 ratio to receive an Absorb everolimus-eluting bioresorbable scaffold or a Xience stent. With the aim of minimizing the problems observed in previous studies, the Absorb IV protocol excluded small caliber (<2.5 mm) vessels and included mandatory aggressive pre-dilation followed by non-complacent balloon post-dilation. Patients could...
Although there are 4 approved bioresorbable scaffolds (BRS) in Europe, experts suggest that current drug-eluting stents (DES) are the best option for coronary angioplasty. These new guidelines jointly published by the European Society of Cardiology (ESC) and the Association of Percutaneous Cardiovascular Interventions (EAPCI) are an update on the use of BRS in clinical practice...
J Am Coll Cardiol Intv has recently published a special issue on bioresorbable scaffolds. Abbott’s decision to pull Absorb off the market probably prompted the fast publishing of all related articles sent to the journal. Bioresorbable scaffolds were developed in hopes that they would reduce the rates of events per year 1 year post-implantation by 1.5%-3%...
