MARLBOROUGH, Mass., May 9, 2011 /PRNewswire/ -- CardioFocus, Inc., developer of the HeartLight Endoscopic Ablation System for the transcatheter treatment of Atrial Fibrillation (AF), announced its technology enables a Pulmonary Vein (PV) acute isolation rate of nearly 99%, with approximately 86% of PVs remaining persistently isolated after three months. Additional research also suggests that 65% of patients achieve durable freedom from AF after a single procedure.
New clinical results supporting the safety and efficacy of the HeartLight System were presented at Heart Rhythm 2011, the Heart Rhythm Society's 32nd Annual Scientific Sessions, in San Francisco, CA. The presentations included data from both a 200-patient international, multicenter clinical experience with the CardioFocus device (15 sites across four countries) and from a unique study that employed intracardiac diagnostic remapping on 56 paroxysmal AF patients, whether or not they were symptomatic, to determine the rate of persistent PV isolation.
"These recent clinical experiences support the promise of the HeartLight technology to help patients achieve lasting freedom from paroxysmal AF," commented Stephen Sagon, President and CEO of CardioFocus, Inc. "As shown by the robust data across multiple clinical centers, our proprietary technology, including endoscopic visualization, a compliant balloon catheter and the delivery of light energy, is helping to enhance the reproducibility and efficacy of atrial fibrillation ablation."
In the 200-patient study, titled "Pulmonary Vein Isolation Using the Visually-Guided Laser Balloon: The First 200-Patient Multicenter Clinical Experience" and presented on May 6th, researchers reported nearly 99% of all PVs were isolated following the HeartLight ablation procedure. Of the 107 patients that reached at least 6 months follow-up, 65% remained free from AF after a single ablation procedure. The procedure also demonstrated low complication ra
