ID: ANCE00178S103
MEDICAL ANIMATION TRANSCRIPT: If a significant blockage is found, your doctor will insert a guidewire into the artery. A balloon on the tip of the catheter will be moved along the wire to the blockage. When the balloon inflates, it will expand the artery and improve the blood flow. You may feel some chest discomfort while this is happening. After this, your doctor will deflate and remove the balloon. A wire mesh tube called a stent may be placed in the treated area. The stent helps keep the coronary artery open. Your doctor will choose the proper size stent, which is compressed over a balloon. The stent will be moved into the artery over the same guidewire. When the balloon is inflated, the stent will expand and lock into place. After the balloon catheter is taken out, the stent will stay in place to hold the artery open.
