Description
S Iqbal and colleagues report early rhythm relapse after pulsed field ablation from the SINGLE-SHOT CHAMPION trial, published in 2026. Patients with symptomatic paroxysmal atrial fibrillation were randomized to pulsed field ablation or cryoballoon ablation, and every patient received an implantable heart monitor at the procedure. A ninety-day blanking period was set, during which early recurrences are usually discounted.
Early recurrence struck about forty percent after pulsed field ablation against sixty percent after cryoballoon treatment, and the fibrillation burden during blanking was also lower with the newer energy. Timing mattered most: recurrences confined to the first thirty days often settled, while those appearing later rarely did and drove more hospital visits and repeat ablations. Success rates at one year rose as the blanking window lengthened. The authors argue the evidence supports shortening the standard blanking period.
