What the CONVERGE Trial Found — Combined Ablation for Persistent AFib

Researchers tested a hybrid procedure combining heart surface and inside catheter ablation versus standard catheter ablation alone for persistent atrial fibrillation. The combined approach kept 68% of patients free from irregular heart rhythm at one year, compared to 50% with catheter ablation alone.

What the trial was testing

The CONVERGE enrolled 170 patients with atrial fibrillation. The study was sponsored by AtriCure, Inc. and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.

What the results showed

68% of patients stayed in normal rhythm at one year with the combined approach versus 50% with standard catheter ablation.

These findings — that two-thirds of patients using the combined approach stayed in normal heart rhythm at one year — were published in the Circulation. Arrhythmia and electrophysiology and represent the headline result of the study.

Researchers tracked outcomes across 170 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with atrial fibrillation, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

This hybrid procedure is FDA-approved and available for persistent atrial fibrillation that hasn't responded to other treatments. It combines minimally invasive surgery on the heart's surface with catheter ablation from inside. Ask your electrophysiologist if you're a candidate, especially if you've tried catheter ablation before without success or have long-standing persistent AFib.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
