Implementation of primary angioplasty in Europe: stent for life initiative progress report.
Primary percutaneous coronary intervention (PPCI) is the recommended treatment for patients with acute ST-segment elevation myocardial infarction (STEMI). Despite substantial evidence of its effectiveness, a 2007 study reported that only 40-45% of European STEMI patients were treated with PPCI, with large variations in treatment availability between countries. In 2008, the Stent for Life (SFL) initiative was launched by the European Association of Percutaneous Cardiovascular Interventions and EuroPCR in partnership with the European Society of Cardiology (ESC) Working Group on Acute Cardiac Care and country-specific national cardiac societies. The aim is to promote the prioritisation of percutaneous coronary intervention treatment towards those who will benefit most, namely STEMI patients. The following countries are currently participating: Bulgaria, Egypt, France, Greece, Italy, Portugal, Romania, Serbia, Spain and Turkey. ⋯ This report summarises the progress of the SFL initiative in the 10 target countries.

First-in-man use of a novel embolic protection device for patients undergoing transcatheter aortic valve implantation.
We describe the first-in-human experience with a novel cerebral embolic protection device used during transcatheter aortic valve implantation (TAVI). One current challenge of TAVI is the reduction of procedural stroke. Procedural mobilisation of debris is a known source of cerebral embolisation. Mechanical protection by transient filtration of cerebral blood flow might reduce the embolic burden during TAVI. We aimed to evaluate the feasibility and safety of the Claret CE Pro™ cerebral protection device in patients undergoing TAVI. ⋯ The use of the Claret CE Pro™ system is feasible and safe. Capture of debris in more than half of the patients provides evidence for the potential to reduce the procedural cerebral embolic burden utilising this dedicated filter system during TAVI.

To report our first-in-man experience with a new cerebral embolic deflection device (SMT Embolic Deflection Device) during transcatheter aortic valve implantation (TAVI). A significant number of strokes and brain infarcts are caused by embolisation of atherosclerotic material, clots and other debris during various phases of invasive cardiac procedures, especially TAVI. The application of a temporary filter in the aortic arch averting dislodged emboli from entering the cerebral circulation might prevent this. ⋯ In this first-in-man experience, the feasibility of a new embolic deflection device is demonstrated. Larger randomised, prospective studies are required to confirm these findings and prove safety and efficacy by reducing the incidence of cerebral embolism and stroke after TAVI.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of biolimus eluted from an erodible stent coating with bare metal stents in acute ST-elevation myocardial infarction (COMFORTABLE AMI trial): rationale and design.
Compared with bare metal stents (BMS), early generation drug-eluting stents (DES) reduce the risk of revascularisation in patients with ST-elevation myocardial infarction (STEMI) at the expense of an increased risk of very late stent thrombosis (ST). Durable polymer coatings for controlled drug release have been identified as a potential trigger for these late adverse events and this has led to the development of newer generation DES with durable and biodegradable polymer surface coatings with improved biocompatibility. In a recent all-comers trial, biolimus-eluting stents with a biodegradable polymer surface coating were found to reduce the risk of very late ST by 80% compared with sirolimus-eluting stents with durable polymer, which also translated into a lower risk of cardiac death and myocardial infarction (MI) beyond one year. ⋯ The COMFORTABLE AMI trial will determine whether biolimus-eluting stents with biodegradable polymer are superior to bare metal stents of otherwise identical design. This is the first randomised controlled trial (RCT) investigating DES with a biodegradable polymer surface coating for drug release in the treatment of patients with STEMI.

Reoperation for bioprosthetic heart valve failure is associated with significant morbidity and mortality, particularly in high-risk patients. Transcatheter valve-in-valve (VIV) implantation may offer a less invasive alternative. The aim of this study was to report our initial experience with transcatheter VIV implantation to treat degenerated tissue valves. ⋯ Transcatheter implantation of the Edwards THV within a degenerated aortic bioprosthesis, performed predominantly via the transfemoral route, is feasible and associated with good periprocedural and clinical outcomes in high-risk surgical patients.
