The report of FDA-mandated prospective evaluation of outcomes after Cox Maze-IV for atrial fibrillation during cardiac surgery for other problems.  It utilized the Synergy ablation system and focused on absence of AF off antiarrhythmics at 6 months and the absence of major adverse events at 30 days.  76% were AF free, and 9.1% experienced major compl

Results of a multicenter trial of a leadless transcatheter pacing system were reviewed in 300 pts at 6 mos.  Implantation was successful in 99%.  Safety was assessed as freedom from system-related or procedure related complications, and was 96%.  Efficacy was assessed as stable pacing capture at low voltage and was 98%.  25 pts suffered major complic

The authors retrospectively reviewed the postoperative TEEs on patients undergoing DCCV within 30 days after cardiac surgery that included LAA closure (n=93 patients).  The presence of a residual communication between the LAA and the left atrium was 37% overall.

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.
