Success rate and safety of catheter ablation in preexcitation syndrome: A comparison between adult and pediatric patients.

Success rate and safety of catheter ablation in preexcitation syndrome: A comparison between adult and pediatric patients. Cardiol J. 2020 Mar 24;: Authors: Pietrzak R, Franke M, Gawałko M, Lodziński P, Balsam P, Grabowski M, Werner B Abstract BACKGROUND: In contrast to adults, in whom cardiac rhythm disorders are mainly conditioned by coronary artery disease, in children, arrhythmias are most often associated with inherited heart disorders. Catheter ablation (CA) has an important role in the management of cardiac arrhythmias, in adults and children. The aim of the study was to assess and compare the efficacy and safety of CA in children and adults with preexcitation syndrome. METHODS: The study population comprised 43 adults and 43 children diagnosed with a Wolff-Parkinson-White syndrome (WPW). The mean age of the study population was 41 ± 15 years for adults and 14 ± 2.5 years for children. In all patients, an electrophysiological study and CA were performed. Analysis with respect to the procedure duration, fluoroscopy exposure time, location of accessory pathways (AP), immediate success rate and complications were performed. RESULTS: Electrophysiological study revealed the most frequent presence of left-sided AP (56% in children and 70% in adults). The mean procedure duration was 96 ± 36 min and 106 ± 51 min in children and adults, respectively (p = NS). The mean fluoroscopy duration was 8.5 ± 4.3 min and...

CONCLUSIONS: Further studies are required in order to establish the complicated association between SARS-CoV-2 infection and its effects on the cardiovascular system. Our knowledge regarding diagnostic approaches, therapeutic management and preventive measures is constantly enriched throughout an abundance of ongoing research in the respective fields.

This study evaluates the accuracy of EWI for localization of various arrhythmias in all four chambers of the heart before catheter ablation. Fifty-five patients with an accessory pathway (AP) with Wolff-Parkinson-White (WPW) syndrome, premature ventricular complexes (PVCs), atrial tachycardia (AT), or atrial flutter (AFL) underwent transthoracic EWI and 12-lead ECG. Three-dimensional (3D) rendered EWI isochrones and 12-lead ECG predictions by six electrophysiologists were applied to a standardized segmented cardiac model and subsequently compared to the region of successful ablation on 3D electroanatomical maps generated b...

on RH Abstract Cardiac arrhythmias, notably Wolff-Parkinson-White syndrome, are known to represent a major issue in patients with Ebstein's malformation of the tricuspid valve. Abnormal conducting circuits, however, can also be produced by pathways extending either from the atrioventricular node or the ventricular components of the atrioventricular conduction axis, direct to the crest of the muscular ventricular septum. We hoped to provide further information on the potential presence of such pathways by investigations of six autopsied examples of Ebstein's malformation. All were studied by histological sectioning...

We present a case of a young asymptomatic patient who developed acute atrial fibrillation with antegrade conduction over the atrioventricular bypass tract and very high ventricular rate after accidental low voltage electric injury, which was reverted successfully by DC shock.

AbstractPurpose of ReviewThe purpose of this paper is to review the presentation, mechanism and acute management of pediatric tachyarrhythmias and to discuss current updates in the literature.Recent FindingsIn 2015, the AHA updated the PALS guidelines to include lidocaine as a first line agent alongside amiodarone in the management of ventricular tachycardia. A recent study re-addressed the safety of the use of adenosine on heart transplant patients with supraventricular tachycardia (SVT). Also, there have been recent studies which explored alternative prevention modalities for postoperative junctional ectopic tachycardia ...

Wolff-Parkinson-White (WPW) syndrome is a rare pre-excitation syndrome which develops when atrioventricular conduction occurs through a pathologic accessory pathway known as the bundle of Kent instead of atrioventricular node, hence resulting in tachycardia. Patients with WPW syndrome may experience various symptoms arising from mild-to-moderate chest disease, palpitations, hypotension, and severe cardiopulmonary dysfunction. These patients are most often symptomatic because of cardiac arrhythmias.

A recently developed, ECG-based, three dimensional (3D) electrocardiomapping modality named Electrocardiographic Imaging (ECGI) has refined non-invasive diagnosis of heart rhythm disorders [1][2][3]. Our clinical experience in using this non-invasive mapping technique to identify the sources of electrical disorders and guide catheter ablation of atrial arrhythmias (premature atrial beat, atrial tachycardia, atrial fibrillation), ventricular arrhythmias (premature ventricular beats) and ventricular pre-excitation (Wolff-Parkinson-White syndrome) is described below.

During epileptic seizures, cardiac arrhythmias are not uncommon findings. Most of them are benign, although sometimes they can be a life-threatening situation. The combination of a Wolff-Parkinson-White syndrome with atrial fibrillation is a potentially lethal situation but can be definitively treated.
