We are one of only a handful of centers in the United States that provide a complete suite of approaches to AFib, including hybrid procedures with epicardial robotic surgery in conjunction with endocardial ablation. Current research seeks to understand the mechanisms of atrial fibrillation, which appear to come from multiple areas at the same time.Īt the University of Chicago Medicine, our team uses special catheters that allow them to know how much force is being applied onto the tissue, which has been shown to improve the success rate for the procedure. We start with the initial set of treatments and then we get more aggressive as the pest problem declares itself to be more and more stubborn. We come in and we do a treatment and we can control the cases but frequently it requires multiple treatments. We give patients the analogy that atrial fibrillation is like a pest problem in your home. Similar to atrial flutter, treatment options for AFib include anticoagulation (blood thinners) and controlling the arrhythmia with medication or catheter ablation therapy.Īblation is also effective in 60% to 70% of AFib patients. ![]()
