Pulmonary vein isolation (PVI) induces left atrial (LA) volume reduction, known as reverse remodelling (RR). The related changes in LA shape have not yet been evaluated. Left atrial sphericity (LASP) is a new shape-based marker of remodelling that compares LA geometry and a perfect sphere and is a powerful predictor of PVI success. We aimed to evaluate the effect of PVI on LASP and describe the concept of spherical and volumetric RR.
