Description
Omar Hassan, Hadi Hassan, Shuvam Prasai, Fiza Rajput, and Julio Garcia published a study in 2026 on swirling blood flow inside the heart's left atrium in patients with atrial fibrillation. The erratic rhythm lets blood stagnate and clot, and a vein-isolation ablation is the standard fix. How the treatment changes the atrium's vortex patterns, not just its stagnation, was unclear.
Four-dimensional flow MRI measured vorticity and vortex size in 107 patients before ablation, 56 after, and 19 healthy controls. Before treatment, vorticity ran low; after ablation it matched the controls. Vortex volume, though, stayed enlarged in both patient groups. Spin strength recovers while the swollen swirl remains, the authors note, so the two measures report different sides of the remodeling.
