January 7, 2008 – Patients with atrial flutter and atrial fibrillation may require additional sites of ablation to effectively treat their atrial fibrillation, according to a European-based study of atrial fibrillation patients treated with CryoCor’s Cardiac Cryoablation System, which was published in the December 11, 2007 issue of Circulation.
The purpose of the study was to evaluate the role of atrial flutter in the recurrence of atrial fibrillation and the effectiveness of an ablation strategy focused on isolating the pulmonary veins to treat the atrial fibrillation.
