SUCCESSFUL ABLATION OF CONCEALED ACCESSORY PATHWAY MEDIATED SUPRAVENTRICULAR TACHYCARDIA IN A 5-YEAR-OLD CHILD WITH EBSTEIN ANOMALY.

Here we report a case of a 5-year-old boy with Ebstein anomaly and supraventricular tachycardia. He was diagnosed with Ebstein anomaly at the age of 3 months during the workup for afebrile convulsions, and has been followed by a pediatric cardiologist since. Electrocardiography recorded a small Rr` pattern in V1 on a few occasions, without other abnormalities.

SHOULD PATIENT AGE AND BODY MASS BE TAKEN IN CONSIDERATION WHEN ZERO FLUORO ABLATION IS SCHEDULED?

Since the introduction of 3D mapping systems, the use of x-rays in electrophysiology procedures has significantly decreased. The goal of this study was to analyze the frequency of x-ray use in pediatric electrophysiology in relation to age or body mass, indication for the procedure, and arrhythmia substrate. This retrospective, cross-sectional study included all pediatric procedures in two centers, Gottsegen Cardiovascular Center, Budapest, Hungary and Sestre milosrdnice University Hospital Center, Zagreb, Croatia.

Midseptal and Anteroseptal Accessory Pathway Ablation in Children.

The goal of this study is to document outcomes of ablation for high-risk accessory pathways in paediatrics using 3D mapping systems with minimal to zero fluoroscopy. It is a cross-sectional, multicentre study, conducted between 2013 and 2023, and involving four different centres in Hungary, Croatia, Kuwait, and Slovenia. A total of 128 procedures were performed on 111 patients.

X-ray Doses in Relation to Body Mass, Indication, and Substrate During Pediatric Electrophysiological Procedures on the Heart.

The main goal of this study is to determine typical values of dose area product (DAP) and difference in the effective dose (ED) for pediatric electrophysiological procedures on the heart in relation to patient body mass. This paper also shows DAP and ED in relation to the indication, the arrhythmia substrate determined during the procedure, and in relation to the reason for using radiation. Organ doses are described as well.
