BackgroundCryoablation for pediatric atrioventricular nodal reentry tachycardia (AVNRT) is favored for reducing conduction system injury compared to radiofrequency (RF) ablation. ResultsAmong 95 patients, 69 received RF ablation and 26 received cryoablation. Recurrence rates were 2.9% vs. 11.5%, p>0.99).
ABSTRACT Introduction The aim of this study was to describe our experience and outcome of ablation therapy for arrhythmias in pediatrics at a tertiary care center. All pediatrics presenting to AUBMC between 2000 and 2020 who underwent cardiac ablation were included. Of those, 60% were males with a mean age of 15 years.
IntroductionFocal atrial tachycardia (FAT) is predominant in the pediatric population. A 12-lead electrocardiogram revealed a narrow QRS complex tachycardia with a rate of 157 beats per minute and a prolonged RP relationship. Echocardiography indicated a severely reduced ejection fraction of 22%.
Cardioneuroablation (CNA) is a catheter-based intervention, used to identify and ablate the epicardial ganglionated plexi (GP), which results in disruption of the vagal-mediated parasympathetic input to the sinus and atrioventricular node. with one documented SP after termination of atrial tachycardia at the 3-month follow-up.
Electrophysiological study will show that, and this pathway can be ablated. This is one important cause of supraventricular tachycardia in Ebstein’s anomaly. Periprocedural electrophysiological study and ablation of potential arrhythmic circuits, have been suggested as a preventive strategy.
Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology. Read about Fascicular VT here: Idiopathic Ventricular Tachycardias for the EM Physician Case Continued He was completely stable, so adenosine was administered. See Learning point 1 below.
ABSTRACT Background Low voltage bridge mapping (LVBM) is an approach to atrio-ventricular nodal reentry tachycardia (AVNRT) ablation that has been postulated to facilitate the procedure. In our center, AVNRT ablations were performed with the traditional radio frequency current (RF) current approach using the CARTO mapping system.
PurposeAtrial tachycardia is an uncommon supraventricular tachycardia in children. It is often drug-resistant and likely to occur concomitantly with tachycardia-induced cardiomyopathy, making radiofrequency catheter ablation the preferred treatment. A total of 78.6% No postoperative complications occurred in any patient.
Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular tachycardia in children and congenital heart disease (CHD) patients. Nowadays, in large enough children, chronic treatment for symptomatic and recurrent AVNRT episodes relies on transcatheter ablation.
