Multicenter StudyIntegration of pre-hospital electrocardiograms and ST-elevation myocardial infarction receiving center (SRC) networks: impact on Door-to-Balloon times across 10 independent regions.
The aim of this study was to evaluate the rate of timely reperfusion for ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PPCI) in regional STEMI Receiving Center (SRC) networks. ⋯ Ten independent regional SRC networks demonstrated a combined 86% rate of D2B

Multicenter Study Clinical TrialSafety and efficacy of biodegradable polymer-coated sirolimus-eluting stents in "real-world" practice: 18-month clinical and 9-month angiographic outcomes.
This study sought to evaluate the safety and efficacy of a biodegradable polymer-coated sirolimus-eluting stent (Excel, JW Medical System, Weihai, China) with 6-month dual antiplatelet therapy in daily practice. ⋯ This multicenter registry documents satisfactory safety and efficacy profiles, as evidenced by low rates of major adverse cardiac events and stent thrombosis up to 18 months, for the Excel biodegradable polymer-based sirolimus-eluting stent when used with 6 months of dual antiplatelet therapy in a "real-world" setting. (Multi-Center Registry Trial of EXCEL Biodegradable Polymer Drug-Eluting Stent [CREATE]; NCT00331578).

ReviewPulmonary vein stenosis complicating ablation for atrial fibrillation: clinical spectrum and interventional considerations.
Ablation procedures for atrial fibrillation are being performed with increasing frequency. One of the most serious complications is the development of pulmonary vein stenosis, which occurs in 1% to 3% of current series. The presentation of pulmonary vein stenosis varies widely. ⋯ The use of balloons and larger stents (approximately 10 mm) results in more optimal results than just balloon angioplasty alone; however, even with stent implantation, recurrent restenosis may occur in 30% to 50% of patients. Follow-up of these patients typically involves computed tomography imaging to document restenosis. If significant restenosis is identified, it should be treated promptly because of the potential for progression to total occlusion.
