Key result
Transcatheter ASD closure study evaluates pediatric ventricular repolarization but reports no outcome results.
Why the study?
Atrial and ventricular arrhythmias can occur in children after transcatheter ASD closure, prompting investigation of ventricular repolarization parameters that may indicate arrhythmia risk.
Does transcatheter atrial septal defect closure alter ventricular repolarization parameters in children?
Observational (n=225)
No
Does transcatheter atrial septal defect closure alter ventricular repolarization parameters in children?
No results reported; leaves open whether transcatheter ASD closure alters repolarization parameters in children.
Objectives: Atrial and ventricular arrhythmias can be observed in children after transcatheter atrial septal defect (ASD) closure.This study investigated ventricular repolarization parameters, which are considered to indicate an increased risk of arrhythmias in patients with transcatheter ASD closure. Materials and Methods:The study included 225 patients aged 0-18 years who underwent transcatheter ASD closure at a tertiary medical school university hospital between 2005 and 2020.Heart rate, Pmax, Pmin, Pdispersion, QTmax, QTmin, QTdispersion, QTcmax, QTcmin, QTcdispersion, Tp-e interval, Tp-e/QT, and Tp-e/QTc values were calculated electronically in 12-lead electrocardiographies (ECGs) taken before the procedure and at 24 h, 1, 6, and 12 months after the procedure.

Yıldız et al. (2023) conducted an observational in Atrial septal defect (n=225). Transcatheter atrial septal defect closure vs. Baseline (pre-procedure) was evaluated on Ventricular repolarization parameters (Heart rate, Pmax, Pmin, Pdispersion, QTmax, QTmin, QTdispersion, QTcmax, QTcmin, QTcdispersion, Tp-e interval, Tp-e/QT, and Tp-e/QTc).
