Admittance to Detect Alterations in Left Ventricular Stroke Volume
Source: Heart Rhythm - June 27, 2014 Category: Cardiology Authors: Erik R. Larson, John E. Porterfield, Sandeep Sagar, Juan Marmol-Velez, Manoj Panday, Daniel Escobedo, Joel Michalek, Yongjian Ouyang, Jonathan W. Valvano, John A. Pearce, Marc D. Feldman Source Type: research

A Multi-Center Study on Acute and Long-Term Safety and Efficacy of Percutaneous Left Atrial Appendage Closure using an Epicardial Suture Snaring Device
Pericardial suture ligation of the left atrial appendage (LAA) may be an alternative to endoluminal devices for stroke prevention in atrial fibrillation (AF) patients, but multicenter safety and efficacy data in high-risk patients with contraindications to oral anti-coagulation is lacking.

Successful Catheter Ablation Decreases Platelet Activation and Improves Endothelial Function in Patients with Atrial Fibrillation
Nonvalvular atrial fibrillation (AF) confers a five-fold increased risk of stroke. Whether catheter ablation (CA) subsequently decreases prothrombotic risk is unknown.

Newly Detected Atrial High Rate Episodes Predict Long-Term Mortality Outcomes in Patients with Permanent Pacemakers
Subclinical atrial high rate episodes (AHREs) detected by implanted devices in patients without prior history of atrial fibrillation (AF) have been associated with an increased risk of stroke and systemic embolism. Data regarding the long-term survival of patients with permanent pacemakers and newly detected AHREs are limited.

EP News: Allied Professionals
In this study by van Diepen et al (Am Heart J 2014;168:60, PMID 24952861) mined data from several large Canadian databases to find 32,160 patients with NVAF undergoing noncardiac surgery over a 10-year period and then applied several risk scores to this group to see which best predicted 30-day mortality, stroke, transient ischemic attack, or systemic embolism.

Multicenter study on acute and long-term safety and efficacy of percutaneous left atrial appendage closure using an epicardial suture snaring device
Pericardial suture ligation of the left atrial appendage (LAA) may be an alternative to endoluminal devices for stroke prevention in patients with atrial fibrillation, but multicenter safety and efficacy data in high-risk patients with contraindications to oral anticoagulation are lacking.

A formidable “TASK”: Tipping the balance in favor of rhythm control for the management of atrial fibrillation
Atrial fibrillation (AF) is a major public health epidemic that increases the risk of stroke and heart failure.1 Therapeutic approaches for AF include ablation techniques and pharmacologic agents. The goal of the former strategy is to convert AF by burning or freezing foci of arrhythmogenic triggers or imposing anatomical barriers that disrupt the reentrant circuits that maintain AF. An alternative to ablation is the use of pharmacologic strategies that are either curative (when AF is amenable to conversion) or ameliorative (when it is not).

Risk predictors of stroke and mortality after ablation for atrial fibrillation: The California experience 2005–2009
Ablation (ABL) is a second-line therapy for the management of atrial fibrillation (AF). Single-center studies have demonstrated the safety and efficacy of ABL; however, the low event rates render it difficult to assess predictors of major adverse events.

Risk of new-onset atrial fibrillation and stroke after radiofrequency ablation of isolated, typical atrial flutter
Radiofrequency ablation (RFA) is considered a curative procedure for typical atrial flutter (AFL); however, patients remain at risk for developing new atrial fibrillation (AF).
