Stroke After Surgical Left Atrial Appendage Clip With Residual Neck Thrombus: Transcatheter Plug Closure.

BACKGROUND Incomplete left atrial appendage clip closure is a recognized complication and may increase thromboembolic risk. CASE SUMMARY A 72-year-old woman with persistent atrial fibrillation presented with a left middle cerebral artery stroke while on apixaban. History included mitral valve repair with epicardial l...

The Lazarus Protocol: Rescue Catheter Ablation of Incessant Ventricular Fibrillation by Purkinje Substrate Denetworking in Critically Ill Patients With Ischemic Cardiomyopathy.

We report a case series of 3 critically ill patients with refractory incessant ventricular fibrillation (VF) who underwent catheter ablation using high-density mapping of the Purkinje system during ongoing VF, combined with targeted Purkinje denetworking and myocardial substrate modification. All patients were supporte...

Effects of Dual-Energy Lattice-Tip Catheter Ablation of Ventricular Arrhythmias on Cardiac Implantable Electronic Device Performance.

BACKGROUND The Sphere-9 lattice-tip catheter (Affera, Medtronic) enables delivery of both radiofrequency ablation (RFA) and pulsed field ablation (PFA) for ventricular arrhythmia (VA) ablation. Data on its impact on cardiac implantable electronic devices (CIEDs) are limited. OBJECTIVES This study sought to evaluate c...

Anatomical Approach from Aortic Sinus of Valsalva for Para-Hisian Premature Ventricular Contractions: Safety and Outcomes.

BACKGROUND The optimal ablation strategy for para-Hisian premature ventricular contractions (PVCs) remains uncertain because of the risk of conduction system injury. OBJECTIVE To evaluate the safety and outcomes of catheter ablation for para-Hisian PVCs, with particular focus on the efficacy and safety of an anatomic...
