ABSTRACT Background Concomitant pulmonary vein isolation (PVI) and left atrial appendage occlusion (LAAO) is increasingly performed in patients with atrial fibrillation (AF) at elevated thromboembolic risk. Radiofrequency ablation (RFA) has been the conventional approach, but pulsed field ablation (PFA) may reduce tissue edema, procedural duration, and

High-resolution mapping and ablation of recurrent left lateral accessory pathway conduction
Proper localization of the anatomical target during ablation of the accessory pathways (AP) and the ability to detect clear AP potentials on the ablation catheter are crucial for successful AP ablation.

In a three‐phase comparison (fluoroscopy‐only, 3D‐blinded, and real‐time 3D‐EAM), 23.8% of blinded procedures missed at least one pulmonary vein. Real‐time 3D mapping eliminated missed veins and reduced PVI applications. 3D‐EAM, three‐dimensional electroanatomical mapping; CT, computed tomography; LA, left atrium; PV, pulmonary vein.

ObjectiveCurrently radiofrequency and cryoballoon ablations are the two standard ablation systems used for catheter ablation of atrial fibrillation; however, there is no universal consensus on which ablation is the optimal choice.

Sustained Idiopathic Outflow Tract Ventricular Tachycardia: Clinical Evidence for RVOT Predominance
ABSTRACT Background Idiopathic outflow tract premature ventricular contractions (PVCs) are most commonly localized in the right ventricular outflow tract (RVOT). The clinical significance of sustained outflow tract ventricular tachycardia (OT‐VT) regarding any predominance to one specific anatomic area remains uncertain.

Idiopathic Fascicular Ventricular Tachycardia [PDF]
Idiopathic fascicular ventricular tachycardia is an important cardiac arrhythmia with specific electrocardiographic features and therapeutic options. It is characterized by relatively narrow QRS complex and right bundle branch block pattern. The QRS axis

Percutaneous Catheter Ablation of Epicardial Accessory Pathways. [PDF]
Radiofrequency (RF) catheter ablation is the treatment of choice in patients with accessory pathways (APs) and Wolff-Parkinson-White syndrome. Endocardial catheter ablation has limitations, including the inability to map and ablate intramural or ...

The year in cardiology: arrhythmias and pacing. [PDF]
During this last year, there has been much progress with regard to anticoagulant and ablation therapy for atrial fibrillation (AF). Apart from recently issued European Society of Cardiology Guidelines for the management of patients with supraventricular ...

Modified Anatomical Ablation Strategy for Mitral Isthmus
ABSTRACT Background Durable mitral isthmus (MI) block remains challenging in persistent atrial fibrillation (AF) ablation. Ethanol infusion into the vein of Marshall (EI‐VOM) enhances efficacy, but the minimal endocardial ablation extent post‐EI‐VOM is undefined.

Cryoballoon or Radiofrequency Ablation for Paroxysmal Atrial Fibrillation. [PDF]
BACKGROUND: Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation.
