AVNRT is an abnormal heart rhythm, or arrhythmia; approximately 319,000 people live with AVNRT and more than 49,000 people are diagnosed each year.1,2
"The expanded indication for this catheter will allow more patients to benefit from a safe and effective therapy that can prevent heart racing, and allow them to get back to their normal activities," said Peter Wells, M.D., heart rhythm doctor at Baylor Heart and Vascular Hospital, Dallas, and principal investigator of the ICY-AVNRT clinical trial.
The expanded indication is supported by data from the Intracardiac Cryoablation for AtrioVentricular Nodal Reentrant Tachycardia (ICY-AVNRT) clinical study, which demonstrated safety and effectiveness of the Freezor Xtra Catheter for the treatment of patients with AVNRT. With 397 enrolled patients in 34 clinical trial sites across the U.S. and Canada, the study showed freedom from AVNRT was 92.6 percent at six months post-procedure. All of the safety endpoints were met, with no primary safety events related to the Freezor Xtra Catheter.
"Medtronic is pleased with the FDA's decision to approve the expanded use of the FreezorXtra Catheter for the AVNRT patient population," said Colleen Fowler, vice president and general manager of the AF Solutions business, part of the Cardiac and Vascular Group at Medtronic. "This treatment option expands our efforts to improve care for these patients."
