Parameter | Probability | #/N | Distribution | Source |
---|---|---|---|---|
No FAV*: fetal demise | 0.15 | 4/27 | Beta | IFCIR |
No FAV: Biv outcome | 0.22 | 5/23 | Beta | IFCIR |
Technical success | 0.81 | 70/86 | Beta | IFCIR |
Post FAV fetal demise | 0.20 | 16/80 | Beta | IFCIR |
TS: Biv outcome | 0.43 | 24/56 | Beta | IFCIR |
Eligible for FAV but not performed due to maternal contraindications, not offered at center, or family declined. Loss to follow-up and terminations were excluded from the denominator of fetal demise. Biv = biventricular circulation; FAV = fetal aortic valvuloplasty; TS = technically successful
