The risk of repeat ablation for the same arrhythmia as the original procedure. Only de novo procedures, deemed acutely successful are included. The numbers for redo procedures within 3 years, include only patients treated 2006 through 2013.
AF, ablation of atrial fibrillation; AT, ablation of atrial tachycardia; AVN, AV-nodal ablation; AVNRT, AV-nodal re-entry tachycardia ablation; AP/WPW, accessory pathway/Wolff–Parkinson–White syndrome; CI, confidence interval; CTI, cavotricuspid isthmus ablation; PVC, ablation of premature ventricular contraction; VT, ablation of ventricular tachycardia.
