Abstract

Percutaneous ablation (PA) for relapsing atrial tachyarrhythmias after surgical ablation is an emerging therapy. The aim of this study is to report the electrophysiological findings and the procedural long-term outcomes of reablation, in this particular clinical setting. We retrospectively analysed all patients who were readmitted to our centre for relapsing atrial arrhythmias after surgical ablation for atrial fibrillation (AF). From 2000 to 2011, 36 patients with previous surgical ablation of AF received additional percutaneous management. Seven patients had had biatrial Maze, 18 left atrial ablation lesion set and 11 pulmonary vein isolation. Energy sources involved were unipolar radiofrequency (RF) (n = 13), bipolar RF (n = 19), combined bipolar RF and cryoenergy (n = 2), cryoenergy (n = 1) and high intensity focused ultrasound (n = 1). The median time to reablation was 34 months (interquartile range: 10-66). The relapsing arrhythmias were left atrial tachycardia (n = 17), AF (n = 15), right atrial flutter (n = 2), right atrial tachycardia (n = 1) and biatrial atrial tachycardia (n = 1). Origin of re-entrant circuits was perimitral (n = 27), around pulmonary veins (PV) including posterior left atrium (n = 15) and cavotricus...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
