Cryoablation used to successfully treat atrial fibrillation at the Montreal Heart Institute
Date:5/11/2011

Montreal, May 11, 2011 The electrophysiology team at the Montreal Heart Institute (MHI) used cryoablation (ablation using cold) to treat a patient suffering from atrial fibrillation, the most common form of cardiac arrhythmia, and one associated with significant morbidity. The procedure was performed by Dr. Peter Guerra, Chief of Electrophysiology, and Dr. Marc Dubuc, cardiologist and specialist in electrophysiology. This was a first in Canada following the approval of the Arctic Front device by Health Canada.

The patient, a 71 year old man, had suffered from arrhythmia for a number of years, and medications had been ineffective, so a catheter procedure was therefore necessary. He responded favourably to the procedure.

The Arctic Front device was developed in Montreal and is manufactured by Medtronic. Using this new tool, the Montreal Heart Institute cardiologists can treat the patient more quickly and efficiently, compared to the traditional heat ablation. As a result, the risks of complication associated with this treatment, including the risk of recurrence is reduced significantly. "Cryoballoon technology is a major improvement over the traditional approach for the treatment of atrial fibrillation," said Dr. Dubuc, who is also an associate professor of Medicine at the Universit de Montral. "The delivery of circumferential lesions around the pulmonary veins reduces the duration of the procedure while being effective and safe for the patient."

The STOP AF (Sustained Treatment of Paroxysmal Atrial Fibrillation) study, demonstrated the safety and efficacy of the Arctic Front device in treating and eradicating paroxysmal atrial fibrillation. "We are pleased with the success we obtained using cryoablation in the North American trial STOP AF and our patients have done extremely well. Now, at l
