Table 1 Hemodynamically significant congenital anomalies of the coronary arteries

From: Doppler findings in a rare Coronary Artery Fistula

Isolated/primary – without CHD: Secondary – with CHD:
• Congenital coronary artery fistula • PA + IVS
• Anomalous origin of accessory coronary arteries from the pulmonary artery • AA + MS
• Ectopic origin of the coronary arteries from aortic sinus  
• Absence of a coronary artery  
  1. AA: aortic atresia; CHD: congenital heart disease; IVS: interventricular septum; MS: mitral stenosis; PA: pulmonary atresia – modified from [2]
