• Coronary artery fistulae (CAFs) are abnormal connections of a coronary artery to a cardiac chamber or vessel. There is a paucity of data regarding clinical outcomes, especially when detected prenatally. This was a multicenter retrospective cohort study of all CAF cases from 2002 to 2016. Clinical characteristics and outcomes were compared between the prenatal and postnatal cohorts. A scoping literature review of prenatal CAFs was completed. CAFs were diagnosed prenatally in 12 (median, 23 weeks’ gestation; interquartile range, 17-36 weeks’ gestation) and postnatally in 94 (median, 2.8 years; interquartile range, 0-15 years) cases. Structural heart defects were present in five (42%) prenatal and 19 (20%) postnatal cases (P = .011) and genetic conditions in five (42%) and 14 (15%), respectively (P = .001). CAFs were considered large in 12 (100%) prenatal versus 14 (15%) postnatal cases (P < .001). The CAF distribution was similar between cohorts: 39 (67%) from the left and 19 (33%) from the right coronary artery, with the most common exit sites being the main pulmonary artery 54 (51%), right ventricle 30 (28%), and right atrium 12 (11%). Of prenatal cases, all large at presentation, none progressed, six (50%) resolved by birth, and one (8%) underwent elective neonatal ligation. Of postnatal cases, one presented in cardiogenic shock, and no other case had ventricular dysfunction, arrhythmias, or ischemic changes. Nine (10%) with large shunts underwent intervention (seven percutaneous, two surgical), of whom three were symptomatic. Two (17%) prenatal and two (2%) postnatal cases had coronary abnormalities, two with normal results on stress perfusion imaging. Postnatal death occurred in two (17%) prenatal and four (4%) postnatal cases (P = .05). Of the total 36 prenatal cases reported in the literature, including the 12 cases in the present series, 10 (28%) had clinical symptoms at birth, including three (8%) with cardiogenic shock, and 19 (53%) underwent intervention. Prenatally and postnatally encountered CAFs are associated with a good prognosis for most, with many not requiring intervention. Although half of the prenatal CAFs resolved prenatally, given the risk for cardiogenic shock at birth and heart failure in early infancy, appropriate perinatal planning and postnatal surveillance is warranted. •Large CAFs rarely progress in size throughout gestation.•Regression of CAFs is common.•Given the association with aneuploidy, genetic counseling should be considered.•Fetuses should be monitored after birth for heart failure, arrythmias, and shock.
