Key result
Fetal aortic valvuloplasty was technically successful in a fetus with severe aortic stenosis at 29 weeks of gestation, achieving functional biventricular circulation postnatally.

Does ultrasound-guided percutaneous balloon fetal aortic valvuloplasty achieve biventricular circulation in a fetus with severe aortic stenosis?
Fetal aortic valvuloplasty is technically feasible for severe aortic stenosis and can achieve biventricular circulation, though complications like hemopericardium and bradycardia may necessitate emergency delivery.

Should not yet change practice for fetal aortic stenosis; leaves open its role pending larger prospective studies.
Prenatal intervention of severe fetal aortic valve stenosis by ultrasound-guided percutaneous balloon valvuloplasty has been performed to prevent the progression to hypoplastic left heart syndrome, and achieve biventricular circulation in neonates. Here we report a case of fetal aortic valvuloplasty prenatally diagnosed with aortic stenosis at 24 weeks of gestation and showed worsening features on a follow-up echocardiography. Prenatal aortic valvuloplasty was performed at 29 weeks of gestation, and was a technical success. However, fetal bradycardia sustained, and an emergency cesarean delivery was performed. To the best of our knowledge, this is the first reported case of fetal aortic valvuloplasty which was performed in Asia.

Yoon et al. (2017) conducted a case report in Severe fetal aortic stenosis (n=1). Fetal aortic valvuloplasty was evaluated on Technical success and achievement of biventricular circulation. Fetal aortic valvuloplasty was technically successful in a fetus with severe aortic stenosis at 29 weeks of gestation, achieving functional biventricular circulation postnatally.
