Description
Wanyu Hu and co-authors measured in 2025 what happens to the heart in the first two days after atrial fibrillation ablation. Catheter ablation is known to improve chamber function over the long term. The very early phase, within forty-eight hours, had not been studied closely. The team enrolled 117 patients and recorded pressures and ultrasound measures before and after the procedure.
Pressures in both atria rose right after ablation. At the same time, atrial pumping and the squeezing function of both ventricles improved. Patients with persistent fibrillation improved more than those with the paroxysmal form. One catch appeared: the left ventricle's relaxation was briefly stunned. Chamber sizes did not change. The authors read this as mechanical gains arriving before structural remodeling.
