Focal atrial fibrillation presenting in the origin of atrial tachycardia
Introduction The preferential origin of atrial tachycardia (AT) is generally associated with specific anatomical atrial structures such as crista terminalis, tricuspid annulus, mitral annulus, and pulmonary veins. There are 3 major mechanisms of focal AT: enhanced automaticity, triggered activity, and microreentry. Focal AT can be eliminated via radiofrequency ablation with fairly good long-ter...
متن کاملAtrial Fibrillation : Focal or Reentrant or Both ?
Ablation for atrial fibrillation (AF) is a genuinely viable and increasingly used option for improving quality of life in patients with symptomatic drug-refractory AF. What is remarkable about the limited success achieved with these procedures is that progress has occurred despite a near complete lack of knowledge about what causes or maintains AF. Focal origins for AF were first demonstrated d...
متن کاملFocal Impulse and Rotor Modulation for Paroxysmal Atrial Fibrillation
Therapy for atrial fibrillation (AF) remains suboptimal, largely because of uncertainty in its mechanisms. While the ‘‘triggers’’ versus ‘‘substrate’’ debate continues to rage, it is not clear that this is central. All supraand ventricular arrhythmias are initiated from sinus rhythm by ‘‘triggers,’’ and successful therapy targets their sustaining mechanisms rather than triggers. Paroxysmal AF, ...

متن کاملFocal Atrial Fibrillation from the Superior Vena Cava.
We report the case of a 66 year-old male who underwent catheter ablation for drug-refractory paroxysmal atrial fibrillation (AF) at our institution. Radiofrequency catheter ablation was performed using a three-dimensional electroanatomical mapping system. During ablation of the pulmonary veins (PV), right atrial ectopics were noted to repeatedly trigger AF and atrial tachycardia (AT). After PV ...
