Research shows the sooner an atrial fibrillation surgical procedure is done, the less likely afib is to recur. People in permanent atrial fibrillation who underwent surgery for other heart diseases and had a left atrial ablation procedure for AF at the same time were more likely to be afib-free if the procedure was done within two years and their left atrium size was normal.
Study participants had atrial fibrillation procedures concomitant (at the same time) with open-heart mitral valve, aortic valve, or coronary artery bypass surgery. The procedures were done using either microwave or radiofrequency energy.
The study found that afib recurrence was not influenced by age, gender, primary heart disease, history of blood clots, technology, or use of antiarrhythmic drugs.
