BACKGROUND Despite several advantages of the transradial over the transfemoral approach, the use of transradial access for coronary interventions in daily practice is still low. Major limitations are the technical and anatomical issues related with right radial artery access. The left radial approach may have an advantage from the point of view of the(More)
OBJECTIVE Left radial access (LRA) and right radial access (RRA) have been shown to be safe and effective for coronary arteries catheterisation. However, the differences between the two approaches in terms of radiation exposure are still unclear. The aim of the present investigation is to evaluate in a randomised study, the dose of radiation absorbed by(More)
OBJECTIVE We investigated clinical outcomes after treatment of coronary bifurcation lesions with second generation drug eluting stents (DES). DESIGN Post hoc analysis of a randomised, multicentre, non-inferiority trial. SETTING Multicentre study. PATIENTS All comers study with minimal exclusion criteria. INTERVENTIONS Patients were treated with(More)
Drug-eluting stents have reduced the risk of in-stent restenosis and have broadened the application in percutaneous coronary intervention in coronary artery disease. However, the concept of using a permanent metallic endovascular device to restore the patency of a stenotic artery has inherited pitfalls, namely the presence of a foreign body within the(More)
Percutaneous coronary interventions (PCI) have become a reliable revascularisation option to treat ischaemic coronary artery disease. Drug-eluting stents (DES) are widely used as first choice devices in many procedures due to their established good medium to long term outcomes. These permanent implants, however, do not have any residual function after(More)
AIMS We evaluated the feasibility and the acute performance of the everolimus-eluting bioresorbable vascular scaffolds (BVS) for the treatment of patients presenting with ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS The present investigation is a prospective, single-arm, single-centre study, reporting data after the BVS(More)
BACKGROUND As bioresorbable vascular scaffolds (BVSs) are being increasingly used in complex real-world lesions and populations, BVS thrombosis cases have been reported. We present angiographic and optical coherence tomography (OCT) findings in a series of patients treated in our center for definite bioresorbable scaffold thrombosis. METHODS AND RESULTS(More)
AIMS Bioresorbable vascular scaffolds (BVS) present different mechanical properties as compared to metallic platform stents. Therefore, the standard procedural technique to achieve appropriate deployment may differ. METHODS AND RESULTS Fifty-two lesions treated with a 3 x 18 mm BVS were imaged with optical coherence tomography (OCT) post-implantation and(More)
AIMS The present report describes a novel coronary fractional flow reserve (FFR) system which allows FFR assessment using a rapid exchange microcatheter (RXi). METHODS AND RESULTS The RXi microcatheter is compatible with standard 0.014" coronary guidewires facilitating lesion negotiation and FFR assessment in a wide range of coronary anatomies. In case of(More)
OBJECTIVES This study sought to compare the neointimal response of metallic everolimus drug-eluting stents (DES) and polymeric everolimus bioresorbable vascular scaffolds (BVS) by optical coherence tomography at 1 year. BACKGROUND DES decrease the risk of restenosis by reducing the neointimal response. However, DES may impair strut coverage, and this has(More)
