This article offers a much needed comprehensive overview of temporary pacing strategies specific to cardiac surgical patients.

  Authors describe a technique allowing excellent exposure of the mitral valve while more safely performing cut-and-sew Cox-Maze III.

Patients with afib undergoing elective surgery or invasive procedure who were on coumadin were randomized to bridging with low molecular weight heparin or placebo preoperatively.  The incidence of arterial thromboembolism was .03% in the bridge group and 0.4% in the placebo group, demonstrating non-inferiority of placebo.  The bleeding complication r

This Swedish study was a retrospective review over a 20-year time period that compared survival after out-of-hospital cardiac arrest between those receiving bystander CPR prior to EMS arrival and those not receiving such.  CPR before the arrival of EMS was associated with an increased 30-d survival rate (odds ratio 2.15; 95% CI 1.88-2.45).

The question of whether digoxin increases the risk of death in patients with atrial fibrillation (AF) or congestive heart failure (CHF) continues to be a matter of debate. The authors of this manuscript attempt to find an answer with a meta-analysis and systematic review of the literature.

Patients with persisent or long-standing atrial fibrillation requiring mitral valve surgery were randomized to either surgical ablation or no ablation.  Surgical ablation patients were further randomized to pulmonary vein isolation or biatrial MAZE.  More surgical ablation patients were free from atrial fibrillation than control.

In this manuscript the authors describe their findings in a meta-analysis of 12 randomized placebo-controlled clinical trials involving 2,980 patients undergoing isolated CABG. They found that statin therapy, particularly atorvastatin, initiated before CABG, was associated with a 58% reduction in the risk of postoperative AF.

This thought provoking article by Drew et al., utilized state-of-the art monitoring technology to document the problem of "alarm fatigue" by recording an astounding number of alarm events; 2,558,760 unique alarms were triggered for 461 patients over a 31-day period.

The study investigated management of atrial fibrillation existing at the time of mitral valve surgery, randomizing 260 pts to ablation or observation.  The end point was freedom from afib at both 6 and 12 mos.  Ablation yielded success in 63% compared to 29% of controls, but was associated with a higher risk of pacemaker implant (21% vs 8%).

This is an excellent summary of the pros and cons of LAA occlusion for stroke prevention in non valvular AF.
