AtriCure has announced that enrolment in the ABLATE post approval study (PAS) of its Synergy Ablation System is complete. As 3 October 2014, the ABLATE PAS enrolled 365 patients at 40 hospitals across the United States.

AtriCure expects to release preliminary data from the study in about a year, with a complete report expected to be published in three years.

 

The ABLATE PAS evaluates clinical outcomes in patients with non-paroxysmal (persistent or longstanding persistent) forms of atrial fibrillation who were treated utilising the AtriCure Synergy Ablation System to perform the Maze IV procedure. The non-paroxysmal atrial fibrillation patient group represents about half of the diagnosed patient population and who are extremely challenging to manage with conventional medical therapy or catheter ablation.


“The ABLATE PAS study is intended to build additional evidence of the safety, efficacy and long-term durability of the Maze IV concomitant treatment for atrial fibrillation using AtriCure’s proprietary surgical devices,” says Patrick McCarthy, director of the Bluhm Cardiovascular Institute at Northwestern University Feinberg School of Medicine, Chicago, USA, and lead physician for the ABLATE PAS.


The AtriCure Synergy Ablation System is the first and only medical device to receive Food and Drug Administration (FDA) approval for the treatment of atrial fibrillation in patients with persistent and long-standing persistent atrial fibrillation undergoing coronary artery bypass grafting and/or valve replacement or repair.


The initial ABLATE study was completed prior to AtriC
ure receiving a premarket approval for the Synergy Ablation System. This study reported results that showed 84% of patients free from atrial fibrillation at six months following an open concomitant Maze IV treatment, and 75% of patients free from atrial fibrillation and off of anti-arrhythmic pharmaceuticals at a mean follow-up of 22 months when assessed by 48-hour Holter monitors. According to a company release, the intent of the ABLATE PAS study is to demonstrate the positive results from the Maze IV treatment used in the original ABLATE study is reproducible and reliable when performed at hospitals across the country.
