A congenital giant left atrial appendage (LAA) is a rare condition only described in case reports [1]. Supraventricular tachycardias, including atrial fibrillation (AF), and systemic embolisation are the most common clinical findings [1, 2]. Almost all reported cases are treated by resection of the giant LAA [1]. A few cases are treated conservatively [3, 4]. Catheter ablation has not been repo...

In this retrospective study of 22 patients with the Wolff-Parkinson-White (WPW) syndrome, the cost of catheter ablation in 11 patients was compared with that of surgical ablation in another 11 patients. All patients in the catheter ablation group had a posteroseptal accessory pathway; in the surgical group, 5 patients had a left lateral accessory pathway, 3 had a left lateral and posteroseptal ...

Introduction The management of supraventricular arrhythmias after the Fontan procedure with catheter ablation represents a significant challenge. This can be due to the access problems that are created by the currently used modification of the procedure, which uses an extracardiac conduit, as well as to the complex anatomic substrate that can be created by a combination of congenital and acquir...

Catheter ablation is an accepted, highly effective modality of treatment for cardiac arrhythmias in children. The success rate depends on the operator's experience, especially in cases involving complex anatomies. We hereby report our recent experience of successful ablation of accessory pathways in three children with complex congenital heart diseases. The first case was a 7-year-old girl with...

Introduction Catheter ablation is an important treatmentmodality formanagement of ventricular arrhythmias in the setting of implantable cardioverter-defibrillator (ICD) shocks and ventricular tachycardia (VT) storm. The frequency of patients with nonischemic cardiomyopathy requiring ablation for ventricular arrhythmias is increasing.Arrhythmias of right ventricular (RV) origin are less common t...

Catheter ablation of atrial fibrillation (AF) is now an important therapeutic modality for patients with AF. There is considerable evidence available from several prospective randomized trials demonstrating that catheter ablation of AF is superior to antiarrhythmic drug therapy in controlling AF and that AF ablation improves quality of life substantially. This is especially true for patients wi...

INTRODUCTION No prior studies have quantitatively analyzed the characteristics of bipolar or unipolar electrograms that may be helpful in identifying successful ostial ablation sites in patients with atrial fibrillation undergoing segmental pulmonary vein isolation. METHODS AND RESULTS The characteristics of bipolar and unipolar electrograms recorded at 185 successful and 120 unsuccessful ost...

Background: Catheter and cryoballoon ablation are established treatments for atrial fibrillation. Frequently, substrate modification of the left atrium is performed in patients with persistent AF or evidence of left atrial adverse remodeling. We compared one year outcomes of AF ablation with substrate modification utilizing radiofrequency catheter ablation (RFA) compared to a combination of cry...
