Procedure-related morbidity, mortality and reintervention rates were assessed and compared.Results Admission rate to paediatric intensive care unit (PICU) was lower in the RVOT stent group (22% vs 100%; p<0.001). Thirty-day mortality in the RVOT stent group was (1/60 (1.7%)) compared with (2/41 (4.9%)) in the mBTS group (p=0.565). Mortality until surgical repair was comparable in both groups (5/60, 8.4%, including three non-cardiac death in the RVOT stent group vs 2/41, 4.9% (p=0.698)). Total hospital length of stay was shorter for the RVOT stent group (median 7 days vs 14 days; p<0.003). Time to surgical repair was shorter in the RVOT stent group (median 232 days, IQR 113–360) compared with the mBTS group (median 428 days, IQR 370–529; p<0.001) due to improved pulmonary arterial growth.Conclusion RVOT stenting in Fallot-type lesions can be accomplished safely, with lower PICU admission rate, a shorter hospital length of stay and shorter duration of palliation until complete repair compared with mBTS palliation.
