BACKGROUND: Interatrial stenting has become an essential intervention for children with CHD requiring sustained interatrial communication to optimise systemic and pulmonary haemodynamics. This study aimed to evaluate procedural success, clinical outcomes, and factors influencing haemodynamic improvement in a single-centre paediatric cohort.
METHODS: A retrospective study was conducted on 16 patients who underwent interatrial stenting between 2018 and 2024. Patients were categorised by age as Group 1 (≤12 months, n = 10) and Group 2 (>12 months, n = 6). Demographic, procedural parameters, and follow-up data were analysed.
RESULTS: Sixteen patients (median age 10.5 months, median weight 5.0 kg) underwent interatrial stenting. The most frequent diagnosis was borderline left ventricle (37.5%), followed by hypoplastic left heart syndrome (25%) and myocarditis (12.5%). Procedural success was achieved in 15 of 16 patients (93.8%), with one acute failure due to stent embolisation. The median radiation exposure was 244.5 mGy (interquartile range 123.8-447.0). Radiation exposure correlated positively with patient weight (rs = 0.596, p = 0.015). During a median follow-up of 17.5 months, six patients (37.5%) died, and two required redilation. No stent thrombosis occurred.
CONCLUSION: Interatrial stenting is a safe and effective palliative intervention for paediatric CHD, providing significant haemodynamic improvement and bridging to definitive surgical management.
