Comparison of Pre- and Postnatally Diagnosed Coronary Artery Fistulae: Echocardiographic Features and Clinical Outcomes

Andrea Pisesky, MBBS, Lynne E. Nield, MD, Joanna Rosenthal, MD, Edgar T. Jaeggi, MD, and Lisa K. Hornberger, MD, Toronto, Ontario, Canada; and Edmonton, Alberta, Canada

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.
