Acutus Medical, Inc. 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. 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). AcQBlate required only 250.4 ± 172.2 ml of irrigation during the procedure, significantly less than comparative systems (699 ± 386 min in BLOCK-CTI).

Overall, the study demonstrated comparable outcomes to historic controls with significantly shorter ablation time and lower fluid volumes. 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 complications.
