Fetal cardiac interventional procedures performed between 2011 and 2020. fBAV: fetal balloon aortic valvuloplasty; fBAS+: stent placement in the interatrial septum; fBAS−: balloon atrioseptoplasty; fBPV: fetal balloon pulmonary valvuloplasty; PR death: procedure-related death. A total of 14 fetuses had more than one procedure (8 fetuses had the same procedure twice, 5 fetuses had two different procedures, and 1 fetus had three different procedures). † two pregnancies continue; * one pregnancy continues. Eight fetuses with critical aortic stenosis were hydropic, and six of them needed opening of the interatrial septum after fBAV.
