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...

Catheter ablation is nowadays an established treatment modality for both atrial and ventricular tachyarrhythmias. Manual navigation of the ablation catheter can be challenging in patients with a complex cardiac anatomy due to, for example, (surgically corrected or palliated) congenital heart defects, resulting in a long procedure time and excessive X-ray exposure. In the past decades, sophistic...

Post-surgical arrhythmias include a wide range of arrhythmias occurring late after cardiac surgery and represent a complex substrate for catheter ablation either because of extended scar and remodeling or because of limited access to the area of interest. Novel image integration and ablation tools have made the catheter ablation in this population both feasible and successful. We review a struc...

conclusions: catheter ablation of flutter circuit will not prevent later manifestation of af in 16% of the patients undergoing catheter ablation of the typical afl. bmi was the only independent predictor of af following catheter ablation of the typical afl. objectives; to determine long-term incidence and predictors of af after catheter ablation of typical afl. material and methods: between mar...

INTRODUCTION Catheter ablation of arrhythmias can be challenging in patients with congenital heart disease (1). Besides the complexity of the arrhythmias seen in these patients, variations in the anatomy of the normal conduction system also contribute to that challenge. Arrhythmias following surgical repair of congenital heart defects are particularly more difficult to deal with (2). In this ar...

the use of diagnostic and therapeutic methods for assessing pulmonary vein due to its status as a main source of ectopic beats for the initiation of atrial dysrrythmias is strongly recommended.   we report the case of a 13-year-old girl who was admitted to our hospital with the electrocardiogram manifestation of an ectopic atrial tachycardia. the focus of arrhythmia was inside the right upper p...

Supraventricular arrhythmias are an important and increasing cause of morbidity in adults with congenital heart disease, requiring specific management strategies. Pharmacological treatment has limited efficacy, and is often associated with some side-effects. Major improvements in catheter ablation techniques have opened new opportunities to better understand underlying mechanisms of supraventri...

contexts hepatocellular carcinoma (hcc) is one of the most common malignant diseases in the world. because less than 20% of patients with hcc are resectable, various types of non-surgical treatment have been developed. evidence acquisition at present, radiofrequency ablation (rfa) is accepted as the standard local treatment for patients with hcc because of its superior local control and overall...

Introduction Iliofemoral venous occlusions may sometimes be encountered in patients with congenital heart disease (CHD), because of repeated catheterizations, a cut-down of the femoral vein, insertion of central venous catheters, or surgical venous anastomoses. Consequently procedures for catheter intervention, including catheter ablation, may sometimes become difficult or impossible because of...

Pediatric patients present unique anatomic challenges for catheter ablation. Small patient size requires special adaptation and understanding to perform safe procedures when clinically indicated. The anatomic variations of congenital heart disease also create problems that require pre-procedural preparation for each case in addition to a specialized understanding of a vast anatomic variation an...
