WATERTOWN, Mass., May 12, 2020 /PRNewswire/ — Affera, Inc., a private medical device company focused on innovative cardiac arrhythmia treatment solutions, announced today that its platform was featured prominently in scientific sessions at the Heart Rhythm Society 2020 (HRS) meeting held online May 6-9. Simultaneously, three manuscripts describing pre-clinical experiments and clinical trials with the company’s Pulsed Field Ablation capability were published in Circulation: Arrhythmia and Electrophysiology.
The work presented highlights:
- Safety and acute performance of Affera’s focal Pulsed Field and RF Ablation solution in a 76 patient European multi-center study involving 11 operators.
- Multiple pre-clinical models demonstrating lesion durability as well as tissue specificity associated with pulsed field ablation
- Pulsed Field Mapping: an emerging mapping modality utilizing reversible electroporation
“Early this year, results from a 65-patient multi-center study of paroxysmal and persistent AF treated with our RF Ablation solution were published in JACC: Clinical Electrophysiology. This study demonstrated an unprecedented 99% durable PV isolation across 27 remapped patients and, more importantly, 94% 1-year freedom from any atrial arrhythmia,” stated Doron Harlev, CEO and founder of Affera. “We have now extended our platform to include Pulsed Field Ablation, which was showcased at this HRS meeting along with additional innovations. We look forward to another exciting year as we continue to expand our efforts with the Sphere-9 catheter and beyond.”
“Initial pre-clinical work delivering focal PFA with the Sphere-9 demonstrated lesion durability and the safety markers we expect from this non-thermal therapy modality,” stated Vivek Reddy, M.D., Director of Cardiac Arrhythmia Services for The Mount Sinai Hospital. “These findings translated to exceptional safety and acute performance in a clinical setting. With one device we were able to easily and rapidly create effective RF and PF lesions for pulmonary vein isolation as well as lines of block on the mitral isthmus, roof, posterior box and cavo-tricuspid isthmus. This platform has the potential to transform the way AF therapy is delivered.”
