Postinterventional fetal aortic regurgitation: prevalence, outcome and effects on fetal circulation in large single-center cohort.

ABSTRACT:

Objectives

To analyze the prevalence and severity of fetal aortic regurgitation (AR) after undergoing successful fetal aortic valvuloplasty (FAV) and to evaluate its effects on fetal circulation and left ventricular (LV) growth.

Methods

This was a retrospective review of all fetuses with critical aortic stenosis who underwent successful FAV at our center between 2010 and 2024 for whom postnatal echocardiograms were available in digital format. Fetal and postnatal echocardiographic examinations were analyzed for ventricular and valvular dimensions and characteristics, and Z-scores were calculated for middle cerebral artery (MCA) pulsatility index (PI), umbilical artery (UA) PI and cerebroplacental ratio. AR severity was classified into no/mild AR or significant (moderate/seve
