Review Meta Analysis
Meta-analysis of net long-term benefit of different therapeutic strategies in patients with cryptogenic stroke and patent foramen ovale.
We pooled available data on follow-up events in patients with patent foramen ovale and cryptogenic stroke to evaluate the net clinical benefit of different therapeutic strategies (percutaneous closure vs antiplatelet vs anticoagulant therapy). MEDLINE/PubMed and Cochrane databases and reviewed cited references to identify relevant studies were used; 3,311 patients from 21 clinical studies, both observational and randomized, with follow-up ≥12 months were overall included. ⋯ Patent foramen ovale closure was associated over the long term with significant net clinical benefit versus both antiplatelet and anticoagulant therapy; such benefit was driven by 50% relative reduction of stroke and/or transient ischemic attack versus antiplatelet therapy and by 82% relative reduction of major bleeding versus anticoagulant therapy. In conclusion, results of this large study-level meta-analysis may influence practice patterns in patients with patent foramen ovale and cryptogenic stroke; an individualized approach tailored on both the risk of recurrent cerebral events and the bleeding risk should be used to identify the best therapeutic option (percutaneous closure vs antiplatelet therapy vs anticoagulant therapy).

Comparative Study Observational Study
Comparison of frequency, risk factors, and time course of postoperative delirium in octogenarians after transcatheter aortic valve implantation versus surgical aortic valve replacement.
Postoperative delirium (PD) after transcatheter aortic valve implantation (TAVI) remains to be explored. We sought to (1) determine the incidence of PD in octogenarians who underwent TAVI or surgical aortic valve replacement (SAVR), (2) identify its risk factors, and (3) describe possible differences in the onset and course of PD between treatment groups. A prospective cohort study of consecutive patients aged ≥80 years with severe aortic stenosis who underwent elective TAVI or SAVR (N = 143) was conducted. ⋯ The onset of PD after SAVR could occur at any time during the postoperative evaluation. In conclusion, SAVR in octogenarian patients with aortic stenosis might be considered as a predisposing factor for PD. Our data also suggest that the onset of PD was more unpredictable after SAVR.

Meta Analysis Comparative Study
Meta-analysis of direct and indirect comparison of ticagrelor and prasugrel effects on platelet reactivity.
Studies have linked on-treatment platelet reactivity (PR) to adverse clinical outcomes. Because new P2Y12 inhibitors (prasugrel and ticagrelor) have been predominantly tested against clopidogrel, data on pharmacodynamic comparisons between these 2 drugs are scarce. We compared ticagrelor with prasugrel in a network meta-analysis. ⋯ Similar results were obtained with clopidogrel 150 mg. Ticagrelor 90 mg twice daily was associated with lower PRU (-42.5 [-62.9, -21.9]), lower PRI (-9.3 [-15.6, -3.5]), and lower MPA (-8.9 [-16.4, -1.2]) compared with prasugrel 10 mg. In conclusion, our meta-analysis suggests that ticagrelor achieved significantly lower on-treatment PR compared with prasugrel, with both being superior to clopidogrel standard or high dose.

Multicenter Study Comparative Study
Comparison of balloon-expandable versus self-expandable valves for transcatheter aortic valve implantation in patients with low-gradient severe aortic stenosis and preserved left ventricular ejection fraction.
A relevant proportion of patients, classified as severe aortic stenosis on the basis of valve area ≤1 cm(2), have a mean transvalvular gradient ≤40 mm Hg, despite a preserved left ventricular ejection fraction (LGSAS). We assessed the clinical and hemodynamic impact of transcatheter aortic valve implantation in patients with symptomatic LGSAS at high risk for surgery or inoperable, according to the type of percutaneous valve implanted. Ninety-five patients received an Edwards SAPIEN valve (Edwards Lifesciences, Irvine, California) and 51 received a Medtronic CoreValve (Medtronic, Inc., Minneapolis, Minnesota). ⋯ Estimated survival by Kaplan-Meier at 2 years was 70%. At multivariate analysis, life-threatening or major bleeding, postprocedural aortic insufficiency, and acute kidney injury were the major predictors of an adverse outcome. In patients with LGSAS treated by transcatheter aortic valve implantation, the use of balloon-expandable versus self-expandable valves resulted in similar hemodynamic, early, and long-term clinical outcomes.

Clinical Trial Observational Study
The AFFORD clinical decision aid to identify emergency department patients with atrial fibrillation at low risk for 30-day adverse events.
There is wide variation in the management of patients with atrial fibrillation (AF) in the emergency department (ED). We aimed to derive and internally validate the first prospective, ED-based clinical decision aid to identify patients with AF at low risk for 30-day adverse events. We performed a prospective cohort study at a university-affiliated tertiary-care ED. ⋯ The decision aid included the following: age, triage vitals (systolic blood pressure, temperature, respiratory rate, oxygen saturation, supplemental oxygen requirement), medical history (heart failure, home sotalol use, previous percutaneous coronary intervention, electrical cardioversion, cardiac ablation, frequency of AF symptoms), and ED data (2 hours heart rate, chest radiograph results, hemoglobin, creatinine, and brain natriuretic peptide). The decision aid's c-statistic in predicting any 30-day adverse event was 0.7 (95% confidence interval 0.65, 0.76). In conclusion, in patients with AF in the ED, Atrial Fibrillation and Flutter Outcome Risk Determination provides the first evidence-based decision aid for identifying patients who are at low risk for 30-day adverse events and candidates for safe discharge.
