The field of electrophysiology has long encompassed multiple different strands of science and industry in an attempt to yield better results for our patients. Although subspecialization of electrophysiology and electrophysiologists continues at a pace, at the same time our interdependence on others increases. Managing patients with atrial fibrillation (AF) often requires multiple specialists to assess and treat the comorbidities that our patients have, although when considering who and how to ablate our patients we are increasing using ever more complex imaging and mapping systems. In almost 20 years from the initial description of pulmonary vein isolation, and the acceptance that this is the cornerstone of AF ablation, we are still unable to consistently achieve this apparently simple task. In this issue of JACC: Clinical Electrophysiology, Taghji et al. (2) present their work, which will potentially revolutionize the care of patients with AF and also our understanding of it by demonstrating how to achieve permanent pulmonary vein isolation safely and reliably.
