Survival to Hospital Discharge in the Fetus With Moderate to Severe Mitral Regurgitation Either in Isolation or in Combination With Aortic Valve Stenosis or Atresia, a Fetal Heart Society Collaborative Study.

ABSTRACT:

Background

Case series report high mortality after fetal diagnosis of moderate to severe mitral regurgitation in combination with left atrial dilation, hydrops, or restrictive atrial septum. However, overall outcomes and specific high-risk features remain unclear.

Methods

We performed a multicenter retrospective cohort study of fetuses with ≥moderate mitral regurgitation and normal cardiac connections evaluated January 1, 2005 to January 31, 2016. Fetuses undergoing fetal cardiac intervention (FCI) were described separately. We assessed associations between fetal echocardiographic features and discharge mortality using mixed logistic regression and classification and regression tree modeling, stratified by studies performed <28 and ≥28 weeks gestational age (GA).
