Three-dimensional simulations of coronary artery using finite element analysis are considered as effective means to understand the biomechanical properties after the stent was deployed. Bioresorbable vascular scaffolds are new-generation stents used by people. Intravascular optical coherence tomography is an emerging technique for detecting struts. The common 3 D reconstruction methods are using Intravascular Ultrasound (IVUS) or angiographies. However, it loses the details about geometry model. Fusing of optical coherence tomography and angiography to reconstruct the bioresorbable stented coronary artery based on patient-specific mode is an innovative method to reconstruct the high fidelity geometry...

A previous Task Force of the European Society of Cardiology (ESC) and European Association of Percutaneous Cardiovascular Interventions (EAPCI) provided a report on recommendations for the non-clinical and clinical evaluation of coronary stents. Following dialogue with the European Commission, the Task Force was asked to prepare an additional report on the class of devices known as bioresorbable scaffolds (BRS). Five BRS have CE-mark approval for use in Europe. Only one device-the Absorb bioresorbable vascular scaffold-has published randomized clinical trial data and this data show inferior outcomes to conventional drug-eluting stents (DES) at 2-3 years...

Bioresorbable scaffolds (BRS) represent a novel horizon in interventional cardiology and may lead to some potential long-term advantages including the restoration of vasomotion, positive remodeling and a reduced incidence of late and very-late scaffold thrombosis (ScT). This technology, introduced to overcome limitations of current metallic drug-eluting stents (DES), is constantly and rapidly evolving with many companies working on bioresorbable devices. The aim of this review is to present an update on the most promising scaffolds that are under development...

Diabetes mellitus (DM) and small vessel (SV) disease are two major predictors of adverse outcome in patients treated by percutaneous coronary intervention (PCI), even when last generation metallic drug-eluting stents (DES) are used. Bioresorbable scaffold (BRS) technology has been recently developed to overcome the disadvantages of metallic DES due to their permanent struts. Through the resorption process, BRS may provide a vascular restoration that appears very attractive especially when distal or diffusely diseased coronary segments are involved, as in diabetic patients and SV disease...
