CHICAGO--(BUSINESS WIRE)--Interim results from a study conducted in patients with atrial fibrillation demonstrated that a port access, paracardioscopic Ex-Maze procedure produced favorable outcomes and allowed patients to discontinue antiarrhythmic drugs. Andy C. Kiser, MD, presented the results in a poster session at the American College of Cardiology meeting in Chicago. Epicardial lesions to complete the bi-atrial pattern were created in all patients by coagulating cardiac tissue using the nContact Surgical VisiTrax™ device.
