Background The value of additional ablation beyond pulmonary vein isolation for atrial fibrillation (AF) ablation is unclear, especially for persistent AF. It is uncertain whether substrate modification with additional extensive ablation improves outcomes. We reviewed our experience to determine whether pulmonary vein isolation with additional extensive ablation (PVIEA) improves outcomes compared to pulmonary vein isolation alone (PVIA) for AF ablation. Methods Consecutive cases of patients with PVIA versus PVIEA were compared between September 9, 2013 and December 12, 2020. Procedural data collected include radiofrequency ablation delivery time (RADT) and arrhythmia inducibility. Clinical data collected include sinus rhythm maintenance post‐procedure. Results A total of 235 patients were studied (67 PVIA and 168 PVIEA). RADT was shorter when comparing ablation with PVIA versus PVIEA (32 vs. 40 min; p = .04). More arrhythmias were inducible with PVIEA (p < .01). There was no difference in sinus rhythm maintenance by Kaplan–Meier survival analysis (log‐rank test p = .75), after 3 or 12 months between groups overall, and when stratified by AF type (paroxysmal and persistent), left atrial volume, CHA2DS2‐VASc score, left ventricular ejection fraction, or catheter ablation setting (high‐power short‐duration, standard‐power standard‐duration, temperature‐controlled non‐contact‐force). Conclusion AF ablation with PVIA or PVIEA produces similar sinus rhythm maintenance overall and when stratified by catheter setting and AF type. PVIA reduced procedure times and less arrhythmias were inducible post‐ablation.

Opsoclonus myoclonus syndrome (OMS) is a rare neurological disorder characterized by rapid saccadic eye movements, focal myoclonus, and gait disturbances. Both neoplastic and infectious processes have been found to be associated with OMS. In this report, we present a case of OMS in the setting of a new diagnosis of HIV. After diagnosis, the patient was initiated on antiretroviral therapy in addition to clonazepam with some improvement in her neurological symptoms. It was not until she was started on prednisone as an outpatient that her symptoms completely resolved and she returned to her functional baseline.
