About CONVERGE IDE Trial

The CONVERGE IDE trial is a landmark prospective, randomized trial comparing the Convergent approach to endocardial catheter ablation for patients with persistent or long-standing persistent Afib. The Convergent approach is a multi-disciplinary therapy in which a closed chest epicardial ablation is performed by a surgeon, and then complemented by an endocardial catheter ablation performed by an electrophysiologist. Patients were enrolled at 25 sites across the United States, along with two sites in the United Kingdom.

The CONVERGE study’s primary efficacy endpoint is for enrolled patients to be free from Afib, atrial tachycardia, and atrial flutter, absent class I and III AADs except for a previously failed or intolerant class I or III anti-arrhythmic drugs, with no increase in dosage following the three month blanking period through the 12 months post procedure follow-up visit. The company has submitted final documentation to the Food and Drug Administration and is seeking a pre-market approval (PMA).
