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&lt;0.003). Time to surgical repair was shorter in the RVOT stent group (median 232 days, IQR 113\u2013360) compared with the mBTS group (median 428 days, IQR 370\u2013529; p&lt;0.001) due to improved pulmonary
