Physicians at The Mount Sinai Medical Center in New York became the first in the U.S. to ablate atrial fibrillation using a visually-guided laser balloon catheter. The procedure was performed September 15 by Vivek Y. Reddy, MD, Professor of Medicine and Director of the Cardiac Arrhythmia Service at Mount Sinai Heart, and his colleague, Srinivas R. Dukkipati, MD, Director of Mount Sinai's Experimental Electrophysiology Laboratory.
The procedure marks the first time the device-the "Endoscopic Ablation System" manufactured by CardioFocus Inc.-has been used in human clinical trials in this country. Dr. Reddy is the principal investigator for the national study.
Approximately six million U.S. adults have been diagnosed with atrial fibrillation (AFib), a condition characterized by a rapid and irregular heart beat that can cause serious complications, including stroke, palpitations, fainting and early death. AFib diagnosis has increased over the past two decades and the condition now accounts for one-quarter of all strokes in the elderly.
"This new device has the potential to make AFib ablation more reliable, more reproducible, and more consistent for patients with paroxysmal [intermittent] atrial fibrillation," said Dr. Reddy. "The technology which is currently available leads to widely variable success rates, depending largely on physician skill and experience with the procedure. This visually-guided system with a rotating laser design has the potential to simplify AFib ablation and make it available to more patients than ever, before their paroxysmal AFib becomes chronic [continuous] AFib."
Dr. Valentin Fuster, Director of Mount Sinai Heart and Chair of the European American Guidelines on atrial fibrillation, said, "Such an advance in the treatment of atrial fibrillation is another small step forward to cure the disease without the need for chronic medication."
