Documentation Required
- For thoraco-amniotic shunt (TAS) and pleuro-amniotic shunt: ultrasound documentation of fetal pleural effusion/macro-cystic lung lesion and hydrops, gestational age, pre-procedure counseling, and post-procedure imaging showing reduction in effusion/lesion size and hydrops resolution where applicable.
- For fetal cardiac interventions (e.g., FAV): detailed fetal echocardiography demonstrating critical aortic stenosis with echocardiographic predictors of evolving HLHS (e.g., valve z-scores, ventricular dimensions, pressure gradients), gestational age (mid-gestation candidates), multidisciplinary counseling documentation, and plan for postnatal management and follow-up; documentation that center has required expertise and registry/quality reporting where applicable.
- For LUTO and vesico-amniotic shunting: ultrasound documentation of LUTO (megacystis, oligohydramnios), fetal urine studies results if performed (to assess renal prognosis), counseling about perinatal and long-term renal outcomes, technical plan for shunt placement, and follow-up imaging; note need to document risk of shunt displacement/obstruction and plan for neonatal follow-up.
