Intracardiac echocardiography-guided, anatomically based radiofrequency ablation of focal atrial fibrillation originating from pulmonary veins.
OBJECTIVES In patients with a pulmonary vein (PV) source for atrial fibrillation (AF), we sought the use of intracardiac echocardiography (ICE) to evaluate PV anatomy, guide radiofrequency (RF) ablation and monitor for acute stenosis during ablation. BACKGROUND A focal source for AF may be found in the proximal component of the PVs and can be effectively treated by ablative techniques. Howeve...
متن کاملAlterations of heart rate variability after radiofrequency catheter ablation of focal atrial fibrillation originating from pulmonary veins.
BACKGROUND Transient sinus bradycardia and hypotension have been reported as complications during radiofrequency (RF) ablation of focal atrial fibrillation (AF) originating from pulmonary veins (PVs). This study used heart rate variability (HRV) to evaluate the effects of focal PVs ablation on autonomic function. METHODS AND RESULTS Thirty-seven patients with paroxysmal AF were referred for a...
متن کاملPulmonary veins: preferred site for catheter ablation of atrial fibrillation.
Atrial fibrillation (AF) is one of the most challenging arrhythmias to treat. Many patients have to accept this disorder and the medications required. Nonpharmacologic therapies have emerged as alternative methods of treatment. However, technical difficulty, low success rate, high recurrence, and complications still are obstacles. Pulmonary veins as the most common trigger foci of paroxysmal AF...
متن کاملFocal atrial tachycardia originating from the non-coronary aortic sinus: electrophysiological characteristics and catheter ablation.
OBJECTIVES We sought to investigate electrophysiological characteristics and catheter ablation in patients with focal atrial tachycardia (AT) originating from the non-coronary aortic sinus (AS). BACKGROUND In patients with failed ablation of focal AT near the His bundle (HB) region, an origin from the non-coronary AS should be considered because of the close anatomical relationship. METHODS...
متن کاملElectrophysiological and electrocardiographic characteristics of focal atrial tachycardia originating from the pulmonary veins: acute and long-term outcomes of radiofrequency ablation.
BACKGROUND The objective of this study was to describe the electrophysiological characteristics, anatomic distribution, and long-term outcome after focal ablation (RFA) of pulmonary vein (PV) atrial tachycardia (AT). Both atrial fibrillation (AF) and AT may be due to a rapidly firing focus in the PVs. Whether these represent two aspects of the same process is unknown. METHODS AND RESULTS Twen...
