Multicenter Study
Feedback to providers improves evidence-based implantable cardioverter-defibrillator programming and reduces shocks.
Implantable cardioverter-defibrillator (ICD) shocks are associated with increased anxiety, health care utilization, and potentially mortality. ⋯ Providing programming feedback reports improves adherence to evidence-based shock reduction programming and is associated with lower risk of ICD shocks.

Multicenter Study
Multicenter study of the safety and effects of magnetic resonance imaging in patients with coronary sinus left ventricular pacing leads.
Magnetic resonance imaging (MRI) in patients with left ventricular (LV) leads may cause tissue or lead heating, dislodgment, venous damage, or lead dysfunction. ⋯ MRI scanning was performed safely in non-pacemaker-dependent patients with coronary sinus LV leads who were carefully monitored during imaging without clinically significant adverse effect on LV lead function.

Multicenter Study
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. ⋯ This multicenter experience revealed that pericardial suture ligation with the LARIAT system is technically feasible and acutely efficacious. However, additional improvements are required to minimize the rate of pericardial complications. A randomized study is warranted to accurately define the long-term efficacy and safety profile of percutaneous epicardial suture ligation.

Multicenter Study
Incidence and prediction of ischemic stroke among atrial fibrillation patients with end-stage renal disease requiring dialysis.
Renal dysfunction is a significant risk factor for ischemic stroke in atrial fibrillation (AF). However, the incidence of ischemic stroke and how to predict its occurrence among AF patients with end-stage renal disease (ESRD) are unclear. ⋯ The CHA2DS2-VASc score was useful in predicting ischemic stroke in AF patients with ESRD undergoing dialysis and was superior to the CHADS2 score. The net clinical benefit balancing stroke reduction against major bleeding with anticoagulation in these high-risk patients remains to be defined.

Preparticipation screening programs have been suggested to reduce the numbers of sports-related sudden cardiac deaths (SrSCD). ⋯ The incidence rates of SrSCD in noncompetitive and competitive athletes are not different. The study showed an increase in the incidence rate of SrSCD in persons aged 36-49 years in both noncompetitive and competitive athletes compared to those aged 12-35 years. Importantly, SCD in the general population is much more prevalent than is SrSCD in all age groups.
