Anomalous Origin of the Left Coronary Artery off the Pulmonary Artery |
| The images show an early flush injection of the aortic root which fills a large tortuous right coronary artery, and no left coronary arteryis seen . The second image is later in the injestion and large septal perforators collateralise an LAD and subsequently the pulmonary trunk. The overlay image reveals the arteriovenous fistulaization of the LAD from the RCA.

Pulmonary Atresia with Intact Septum |
| In pulmonary atresia with an intact septum, the right ventricle is unable to eject blood into the pulmonary circulation. Suprasystemic pressures result in the RV forcing the blood into the primitive venous system draining the right ventricle and the blood then flows retrograde into the coronary arteries which are at a lower pressure.

Retrograde Flow Through Venous Sinuses in Severe Pulmonary Stenosis |
| The suprasystemic Pressure generated by severe pulmonary stenosis results in retrograde flow through venous coronary sinuses that occur naturally in the RV
