• OCT

    OCT is a very new technology that allows us to see the inside of a coronary artery. OCT stands for Optical Coherence Tomography

    With traditional angiography, contrast is injected into the coronary artery and the contrast shapes the size of the vessel and any blockages from the outside of the vessel. 

    With OCT, the cardiologist inserts a small catheter into the coronary artery and is able to get a colored picture of the inside of the vessel and can determine the actual length of the blockage and its characteristics. It can also show if the blockage is in one portion of the vessel or occludes the circumference of the vessel. This picture then allows for a thorough pre-procedural lesion assessment. It enables the cardiologist to get accurate device sizing, selection of the vessel segment requiring treatment, and efficient planning of the implantation strategy.  The stent that is implanted in the blockage will be sized and inflated to the actual size of the lesion. Sometimes the OCT will help determine that the blockage is not as severe and requires no intervention, saving time, money, and discomfort for the patient.
