Anomalous coronary artery origin from pulmonary artery and coronary–pulmonary fistulas are the major causes of ischemic cardiopathy in children. Both anomalies are characterized by a connection between a higher and a lower pressure chamber causing coronary steal. However, several mechanisms and associated lesions may be responsible of the different presentations of the “coronary steal phenomenon”. The aim of this review is to highlight the different embryology, anatomical features, clinical presentation, and the diagnostic and therapeutic strategy of these coronary anomalies, despite their similar pathophysiology.

Abstract
Anomalous coronary artery origin from pulmonary artery and coronary–pulmonary fistulas are the major causes of ischemic cardiopathy in children. Both anomalies are characterized by a connection between a higher and a lower pressure chamber causing coronary steal. However, several mechanisms and associated lesions may be responsible of the different presentations of the “coronary steal phenomenon”. The aim of this review is to highlight the different embryology, anatomical features, clinical presentation, and the diagnostic and therapeutic strategy of these coronary anomalies, despite their similar pathophysiology.
