MARLBOROUGH, Mass., Jan. 14, 2013 /PRNewswire/ -- CardioFocus, Inc., developer of the HeartLight® Endoscopic Ablation System for the treatment of atrial fibrillation (AF), announces the U.S. pivotal trial evaluating the safety and efficacy of the HeartLight system is approximately half enrolled.  The study, initiated in 2012, is on track to complete enrollment this year. HeartLight is the first catheter ablation system to incorporate an endoscope for direct visualization of the beating heart, a laser energy source and a compliant balloon catheter.

Burke Barrett, Vice President of Regulatory & Clinical Affairs at CardioFocus, said, "Achieving this enrollment milestone speaks to the clinical need for an advanced treatment for AF, a condition that is only continuing to increase in prevalence. We are excited that so many prominent physicians across the country have joined the trial as investigators and believe in the promise of the technology for their patients. We're on track to conclude enrollment in 2013 and, after the one year follow-up period, will prepare the data for submission to the FDA."

In the U.S., approximately three million people suffer with AF, the most common cardiac arrhythmia. The HeartLight pivotal trial is randomizing the HeartLight system against the THERMOCOOL® Catheter (Biosense Webster), and will randomize an estimated 350 patients in this multi-center U.S. trial.  Currently, over 180 patients have been enrolled at 21 sites; the Company expects to complete enrollment this year. The HeartLight system is CE marked and clinically available in Europe and Australia.

Vivek Y. Reddy, MD, of Mt. Sinai University Medical Center, New York, NY and co-principal investigator of the trial, said, "A key challenge in the treatment of AF has been the durability of the intervention, as historically, a large number of patients who undergo catheter ablation experience a recurrence of the arrhythmia within a year. In this trial, we are investigating whether the unique attributes of the HeartLight technology can impact both acute and chronic freedom from AF, and offer a new option for treating this complex condition."
