ABSTRACT
Introduction The coronary circulation provides blood supply to the myocardium. For one of the most critical fetal organs, matching myocardial blood flow and demand is necessary to ensure cardiac function over a wide variety of physiologic and pathologic conditions. For this reason, the examination of coronary vascular dynamics is becoming increasingly relevant in various fetal conditions. Ultrasound examination of the fetal coronary circulation has become possible through advances in ultrasound technology and a better understanding of human fetal cardiovascular physiology. Although not yet standard clinical practice, continuing trends in ultrasound technology and spreading familiarity with the examination and interpretation are likely to expand clinical applications in the future.1
