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.

Las angiografías se realizan insertando un catéter en la raíz de la aorta o en el ostium de las arterias coronarias. El contraste se inyecta a través del catéter y se obtienen imágenes mediante fluoroscopia. La imagen muestra una angiografía realizada a través de la inyección de medio contraste en la raíz aórtica.

Clínicamente, las angiografías se pueden utilizar para visualizar la vasculatura coronaria y determinar si hay oclusiones. Cuando los vasos sanguíneos se encuentran obstruidos se pueden realizar intervenciones como la colocación de stents.
