World’s first Procedure at Belgium Hospital
IRVINE, Calif., May 2, 2018 /PRNewswire/ -- Johnson & Johnson Medical Devices Companies* announced today that Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of heart arrhythmias, has enrolled and treated the first patient in its QDOT AF Study.** The study will evaluate the delivery of high power, short duration ablation with QDOT MICRO, a novel radiofrequency (RF) ablation catheter for the treatment of paroxysmal atrial fibrillation (AF). The first AF patient was treated successfully at OLV Hospital in Aalst, Belgium, one of eight centers in Europe as part of the study that will enroll up to 50 patients.
An estimated 33 million people worldwide have been diagnosed with AF and its prevalence is projected to increase significantly as the population ages.1 Approximately 70 percent of patients with AF are between the ages of 65 and 85.2
QDOT MICRO is a next generation catheter designed to treat AF in a catheter ablation procedure. In what will be a world-first, it delivers 90 watts of RF power in a four-second temperature-controlled catheter ablation session. Its optimized temperature control and micro-electrode technology is designed to provide more efficient and consistent lesion creation with advanced diagnostics, while simplifying the technique and reducing total ablation time.
“The concept of high power, short duration ablation is novel and a potentially groundbreaking advancement for the industry,” said Tom De Potter, MD, FEHRA, Associate Director, Cardiovascular Center Department of Cardiology, Electrophysiology Section at OLV Hospital.+ “This new modality could result in improvements in clinical outcomes and procedural efficiencies and I look forward to further investigation.”
QDOT MICRO, which is only available for investigational use in Europe, is a steerable multi-electrode catheter with a deflectable tip designed to facilitate electrophysiological mapping of the heart and to transmit RF current to the catheter tip electrode for ablation purposes. In addition to force-sensing technology, the catheter incorporates six thermocouple temperature sensors and three micro electrodes embedded in its tip.
“QDOT MICRO will be a significant advancement in catheter ablation technology that has the potential to elevate the standard of care for atrial fibrillation treatment,” said Shlomi Nachman, Company Group Chair of Johnson & Johnson Medical Devices Cardiovascular & Specialty Solutions. “Biosense Webster has a legacy of leadership in cardiac ablation and we are excited by the prospects this new device may provide for millions of patients.”
