CARLSBAD, Calif., Feb. 06, 2023 (GLOBE NEWSWIRE) -- Acutus Medical, Inc. (“Acutus”) (Nasdaq: AFIB), an arrhythmia management company focused on improving the way cardiac arrhythmias are diagnosed and treated, today announced results from the AcQForce Flutter Study “AcQForce Flutter: Force Sensing RF Ablation with Low Flow Gold Tip Catheter for Typical Flutter”. Results were presented during the Late-Breaking Clinical Trials and First Report Investigations session at the AF Symposium in Boston.

“We are encouraged by the positive results of the AcQForce Flutter Study and our ability to help physicians deliver more efficient ablation therapy,” said David Roman, President & CEO of Acutus Medical. “The study is a critical component of our PMA submission to expand our portfolio in the United States to include a fully integrated mapping and therapy solution, and these data reinforce our conviction that AcQBlate will be an important driver of our growth plans in 2023 and over the long-term.”

AcQForce Flutter Study enrolled 110 patients at 21 sites globally and was designed to evaluate the safety and efficacy of the AcQBlate FORCE sensing ablation catheter and system in the treatment of right atrial typical flutter. Acute success was achieved in 94% of patients and there were no serious adverse events. Ablation time was 13.5 ± 10.0 minutes, 33% less than comparative systems (20.0 ± 14.0 min in BLOCK-CTI) ^1,². AcQBlate required only 250.4 ± 172.2 ml of irrigation during the procedure, significantly less than comparative systems (699 ± 386 min in BLOCK-CTI)¹^,2. Overall, the study demonstrated comparable outcomes to historic controls with significantly shorter ablation time and lower fluid volumes.

“AcQBlate’s novel gold tip ablation catheter performed extremely well during the clinical IDE atrial flutter cases. Short procedural times, stable contact force, and less irrigation volume contributed to efficient and safe ablation procedures. The delivery of low irrigation volumes during ablation should result in better fluid management and post-procedure patient recovery,” said Dr. Gery Tomassoni, Electrophysiologist at Baptist Health Lexington, KY and the principal investigator of the study.

The AcQBlate FORCE sensing ablation catheter and system, which received CE Mark in 2020, is commercially available in Europe. The AcQBlate FORCE sensing ablation catheter was designed to provide consistent, effective therapeutic delivery during cardiac ablation procedures. Its unique gold tip electrode has 4x the thermal conductivity of platinum catheters, which allows for significantly more energy delivery at a lower temperature and low irrigation flow rates³. Recent studies completed with the catheter in Europe have demonstrated excellent performance in a variety of clinical cases with significant reductions in ablation time and without procedural complications⁴.

Acutus submitted its premarket approval application for the AcQBlate FORCE sensing ablation catheter and system on October 3, 2022 and is currently under review.
