Background Tetralogy of Fallot with absent pulmonary valve is associated with high mortality, but it remains difficult to predict outcomes prenatally. We aimed to identify risk factors for mortality in a large multicenter cohort. Methods and Results Fetal echocardiograms and clinical data from 19 centers over a 10-year period were collected.

Background In a recent multicenter study of perinatal outcome in fetuses with Ebstein anomaly or tricuspid valve dysplasia, we found that one third of live-born patients died before hospital discharge. We sought to further describe postnatal management strategies and to define risk factors for neonatal mortality and circulatory outcome at discharge. Methods and Results This 23-center, retrospective study from 2005 to 2011 included 243 fetuses with Ebstein anomaly or tricuspid valve dysplasia.

Background: Accurate prenatal diagnosis of congenital heart disease (CHD) allows for appropriate delivery and postnatal management. Geographic constraints limit access to fetal cardiology subspecialists. In our approach, general pediatric cardiologists are first line in regional prenatal cardiac screening.

Aim: Multidisciplinary foetal centres have recently emerged in partnership with children's hospitals throughout the United States. The aim of this investigation was to describe the patient experience of pregnant women who were referred to our foetal centres for the evaluation of foetal congenital anomalies.

Methods: A qualitative interview study of women referred to our foetal centres was conducted using semi-structured telephone interviews.

Background: Ebstein anomaly and tricuspid valve dysplasia are rare congenital tricuspid valve malformations associated with high perinatal mortality. The literature consists of small, single-center case series spanning several decades. We performed a multicenter study to assess the outcomes and factors associated with mortality after fetal diagnosis in the current era.

Objectives: To determine the extent of voluntary implementation of pulse oximetry screening for critical congenital heart disease (CCHD) in Washington. At the time of the study, there was no state legislative or regulatory mandate for CCHD screening in Washington.

Methods: A Web-based survey was sent to the nurse manager or nurse educator of the well newborn unit at each of the 64 Washington hospitals with active delivery services in May and June 2013.

Introduction: Since 2011, pulse oximetry screening for critical congenital heart disease (CCHD) has been recommended for newborns. Initial implementation guidelines focused on in-hospital births. Recent publications affirm the importance of universal screening, including for out-of-hospital births.

To determine the frequency of prenatal detection among liveborn patients with an interrupted aortic arch (IAA), the accuracy of prenatal diagnosis, and the anatomic features associated with IAA in the fetus. The prenatal diagnosis of an IAA is challenging. The data on the features and outcomes of fetal IAA are limited.
