Abstract
Pulmonary vein isolation (PVI) remains the cornerstone of catheter ablation approaches for atrial fibrillation (AF). Ablation of additional AF triggers has been advocated in addition to PVI for persistent AF to improve long-term success rates. What is unknown about many of these triggers is whether they represent migratory, transient, or durable sources of AF. Gagyi and et al (https://doi.org/10.1016/j.hrcr.2021.05.018) shared a case of a 66-year-old woman with a medical history of hypertrophic cardiomyopathy who was referred for catheter ablation of AF.
