Case Study 1
Shown below are an animated image and a static image depicting RCA bridging collaterals. Outlined in yellow in the image on the right is the collateral vessel; encircled in yellow in the same picture is the site of obstruction in the RCA.
Case Study 2
Shown below are an animated image and a static image depicting coronary artery collaterals from the LAD to the left circumflex artery. Note that the obstruction in the left circumflex is encircled in yellow in the image on the right. Outlined in yellow in the image on the right is the collateral vessel from the LAD to the left circumflex after the site of obstruction.

Case Study 3
Shown below are an animated image and a static image depicting coronary artery collaterals from the left circumflex artery to the right system. Outlined in yellow in the image on the right is the collateral vessel from left circumflex to the RCA. Note how the right system fills when the dye is injected in the left system.
Case Study 4
Shown below are an animated image and a static image depicting coronary artery collaterals. utlined in yellow in the image on the right is the collateral vessel.

Case Study 5
Shown below are an animated image and a static image depicting coronary artery collaterals between the RCA and the LAD. Outlined in yellow in the image on the right is the "whale tail" structure consistent of the distal LAD.
Case Study 6
Shown below are an animated image and a static image depicting coronary artery collaterals between the RCA and the LAD. Outlined in yellow in the image on the right are the collateral arteries.
Case Study 7
Shown below are an animated image and a static image depicting coronary artery collaterals from the left system to the RCA. Outlined in yellow in the image on the right is the distal part of the RCA. The collateral arteries exist between the septal branches and the RCA branches.
Case Study 8
Shown below is an animated image depicting coronary artery collaterals between the RCA and the LAD.
