Catheter ablation of atrial fibrillation originating from extrapulmonary vein areas: Taipei approach

The Role of Left Atrial Muscular Bundles in Catheter Ablation of Atrial Fibrillation

“…If a sustained LA flutter/AF was still induced, cardioversion or infusion of amiodarone with 5 mg/kg was performed to restore sinus rhythm. Non-PV AF was also ablated in the same session (11). We attempt to record the spontaneous onset of extra-PV ectopic activity initiating AF before or after isoproterenol loading.…”

The biatrial substrate properties in different types of paroxysmal atrial fibrillation

“…[8][9][10] Briefly, each patient underwent an electrophysiological study and catheter ablation in the fasting nonsedated state after informed consent was obtained. All antiarrhythmic drugs except amiodarone were discontinued for at least 5 half-lives before the study.…”

“…10 The diameter of the SVC was measured to the nearest distance of the SVC-RA junction. 16 The junction was defined as the point below which the cylindrical superior caval vein flared into the RA.…”

Mapping of Persistent Atrial Fibrillation: How Many Sites, How Many Lines?

“…The non-PV thoracic veins have been the target of extensive investigations [51,52] that have consistently found the superior vena cava (SVC) to be a frequent trigger site [53,54]. The additive value of ablation to isolate the SVC has been confirmed clinically for paroxysmal and persistent AF [54].…”
