Objective: In the present study we aimed to demonstrate clinical characteristics, predictors of procedural success and long term recurrence atrial tachyarrhythmia patients undergoing catheter ablation (CA). Patients Methods: Consecutive who had undergone CA due an in a single centre arrhythmia unit between 2012 – 2020 were screened. Predictors analysed by logistic regression. Results: Study pop...

Tachyarrhythmias occur in patients having congenital heart disease most commonly related to surgically created or naturally occurring conduction obstacles, and to postoperative hemodynamic effects on cardiac muscle. Less frequently, the underlying disease is associated with tachycardia substrates. Thorough knowledge of the patient's congenital anatomy and surgical procedures is required before ...

Radiofrequency catheter ablation (RFCA) was performed on a 5-year-old boy with congenital junctional ectopic tachycardia (JET) that was refractory to medical management. Because of the lack of retrograde atrial depolarization during tachycardia, radiofrequency energy was delivered during atrial overdrive pacing to confirm the presence of preserved atrioventricular (AV) conduction. Although the ...

Ventricular tachycardia (VT) most commonly develops in patients with structural heart disease. Myocardial infarction results in collagen replacement interspersed with surviving myocardium, which alters impulse propagation, facilitating re-entry.1 Aside from the postinfarction substrate, scar-mediated VT occurs in patients with nonischemic cardiomyopathy, Chagas disease, sarcoidosis, arrhythmoge...

INTRODUCTION Surgical strategy for patients born with a physiological univentricular heart has evolved from atrio-pulmonary (AP) Fontan (right atrium (RA) to pulmonary artery) to its modification, total cavopulmonary connection (TCPC), with the goal of reduced post-operative incidence of supraventricular tachycardia (SVT). However, TCPC patients may also present with symptomatic atrial tachycar...

Coronary sinus anomalies are rare congenital defects which are usually coexistent with a persistent left superior vena cava and may be associated with cardiac arrhythmias. We report an unroofed coronary sinus without persistent left superior vena cava diagnosed during a catheter ablation procedure for Wolff-Parkinson-White syndrome. Diagnostic and therapeutic options and outcomes are discussed....

BACKGROUND Improvement in outcome of infants born with congenital heart defects has been accompanied by an increasing frequency of late arrhythmias. Ablation is difficult because of multiple tachycardias in the presence of complex anatomy with limited accessibility. We report on remote-controlled ablation using magnetic navigation in conjunction with 3D image integration in patients with previo...

The aim of this survey was to provide insight into current practice regarding the management of paediatric arrhythmias in Europe. The survey was based on a questionnaire sent via the Internet to the European Heart Rhythm Association (EHRA) electrophysiology research network centres. The following topics were explored: patient and treatment selection, techniques and equipment, treatment outcomes...

Accessory atrioventricular pathways (AP) and dual AV nodal physiology are common substrates for paroxysmal supraventricular tachycardias (SVT) in children and adolescents. Definitive treatment can be achieved by catheter ablation with either radiofrequency (RF) or cryoenergy. Aim of this study was to assess effectiveness and safety of RFand cryoenergy ablation in a paediatric population. During...

A 29 year-old male without any risk factors for coronary artery disease presented with symptomatic sustained ventricular tachycardia. 2-Dimensional (2D) Transthoracic Echocardiogram (TTE) did not reveal any abnormality. When we did a 3-Dimensional (3D) echocardiogram, a small Left Ventricular (LV) aneurysm was detected near the outflow tract. After catheter ablation, the patient was discharged ...
