Visible Heart (functional)
 
 

Angiograms are created by inserting a catheter into the aortic root, or into the individual left or right coronary artery ostia. Contrast is injected through the catheter, or a pig-tail, and imaged using fluoroscopy. The image below show an angiogram created through a contrast injection into the aortic root.

Clinically angiograms can be used to visualize the coronary vasculature and determine if any occlusions or blockages are present. When the vasculature becomes obstructed interventions such as stenting or bypass can be performed.
