Abstract 17324: Post-operative Biatrial Pacing Consistently Decreases Atrial Fibrillation in Cardiac Surgery: A Randomized-controlled Trial Meta-analysis
Background: Due to the populational aging atrial fibrillation (AF) is becoming more prevalent disease, it also commonly presents as a cardiac surgery complication. It is well established that ventricular and even atrial pacing may increase the incidence of atrial fibrillation but there is some suggestion that biatrial pacing may prevent it.
Methods: All randomized controlled trials on biatrial pacing for patients undergoing cardiac surgery were sought in Medline and Cochrane databases during May 2013. Data was extracted by 3 reviewers. We analyzed the data with RevMan 5.2 with fixed effect if P>0.1 and I2<40%, and random effect otherwise.
Results: Twelve studies were found comparing biatrial pacing in post cardiac surgery patients against other pacing modalities. All the studies consistently demonstrated a reduced incidence of atrial fibrillation in the patients receiving the biatrial pacing, an overall 70% reduction in the chance of having it (Figure 1).
Conclusions: Biatrial pacing consistently decreased theincidence of post operative atrial fibrillation and should be considered as a preferential mode for patients undergoing cardiac surgery
