The State of the Absorb Bioresorbable Scaffold: Consensus From an Expert Panel.

Significant progress has been made in the percutaneous coronary intervention technique from the days of balloon angioplasty to modern-day metallic drug-eluting stents (DES). Although metallic stents solve a temporary problem of acute recoil following balloon angioplasty, they leave behind a permanent problem implicated in very late events (in addition to neoatherosclerosis). BRS were developed as a potential solution to this permanent problem, but the promise of these devices has been tempered by clinical trials showing increased risk of safety outcomes, both early and late.

Carotid artery revascularization with distal protection in high-surgical-risk patients in routine clinical practice: rationale and design of the CABANA safety surveillance program.

Background: Continuous improvement in carotid artery stenting (CAS) outcomes, especially for periprocedural death and stroke in high-surgical-risk patients, have been seen in recent randomized trials of CAS versus carotid endarterectomy and CAS registries. However, these studies use stringent inclusion/exclusion criteria for patient, institution, and physician selection. The Carotid Stenting Boston Scientific Surveillance Program (CABANA) study was initiated to evaluate periprocedural outcomes with modern versions of the Carotid Wallstent and FilterWire EZ System for operators with a wide range of clinical specialties, CAS experience and training levels, in patients with a broad range of high-surgical-risk conditions and lesion types.
