Pulmonary vein orifice isolation for eliminating paroxysmal atrial fibrillation after ICD implantation.

Repeated Provocation of Time- & ATP-induced Early Pulmonary Vein Reconnections after Pulmonary Vein Isolation: Eliminating Paroxysmal Atrial Fibrillation in a Single Procedure

How important is the assessment of quality of life after pulmonary vein isolation for paroxysmal atrial fibrillation? Key Words: Quality of life, paroxysmal atrial fibrillation, pulmonary vein isolation, ablation

Atrial fibrillation (AF) is one of the most common symptomatic arrhythmias. In addition to clinical symptoms, patients with AF have an increased risk of stroke and it can cause decrease in exercise tolerance and left ventricular function. The growing interest in the quality of life in patients with AF is related to recent clinical findings, such as patients with symptomatic paroxysmal AF having...

Focal 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 ...

Three-dimensional impedance mapping as an aid to circumferential pulmonary vein isolation in paroxysmal atrial fibrillation.

During circumferential pulmonary vein isolation, radiofrequency lesions are created in the transition zone between the left atrium and the pulmonary veins, outside the ostia, to avoid stenosis. Three-dimensional impedance maps were constructed for 25 patients with paroxysmal atrial fibrillation. In the first 15 patients, impedance was measured inside the pulmonary veins (165.4 +/- 7.5 Omega), t...

Innappropriate Sinus Tachycardia After Superior Vena Cava Isolation In Addition To Pulmonary Veins Isolatin Of Paroxysmal Atrial Fibrillation Cryoballoon Ablation.

We report a case of persistent inappropriate sinus tachycardia (IST) after pulmonary vein and superior vena cava (SVC) isolation with cryoballoon ablation for paroxysmal atrial fibrillation (PAF). After the cryoballoon ablation (CBA) procedure, the patient presented with sinus tachycardia of 105 beats/minute. The patient was successfully treated with metoprolol and ivabradine therapy.
