Background: Transcarotid access is an alternative route for transcutaneous aortic valve implantation (TAVI) in patients with impossible transfemoral access.Aims: We evaluated the safety, effectiveness and early and late clinical outcomes of CoreValve® implantation via the common carotid artery.Methods: Eighteen patients (10 men, 8 women; mean age 84 ± 5 years) at high surgical risk (mean...

We sought to compare operator radiation exposure during procedures using right femoral access (RFA), right radial access (RRA), and left radial access (LRA) during coronary angiography (CA) and percutaneous coronary intervention (PCI). Because of an increased incidence of long-term malignancy in interventional cardiologists, operator radiation exposure is of rising concern. This prospective...

Vascular response to everolimus- and biolimus-eluting coronary stents versus everolimus-eluting bioresorbable scaffolds – an optical coherence tomography substudy of the EVERBIO II trial

QUESTIONS UNDER STUDY: Head-to-head optical coherence tomography (OCT) data comparing metallic stents with bioresorbable vascular scaffolds (BVS) are lacking. This study assessed vascular healing at 9-month follow-up after implantation of everolimus- and biolimus-eluting stents (EES BES) and everolimus-eluting BVS.METHODS: OCT was performed in 74 patients enrolled in the EVERBIO II (NCT01711931)...

In: Circulation: Cardiovascular Interventions, 2015, vol. 8, no. 10, p. e002518

Background—Everolimus-eluting bioresorbable vascular scaffolds have been developed to improve late outcomes after coronary interventions. However, recent registries raised concerns regarding an increased incidence of scaffold thrombosis (ScT). The mechanism of ScT remains unknown.Methods and Results—The present study investigated angiographic and optical...
