Coronary artery stent

Illustration showing a coronary artery stent

When placing a coronary artery stent, your doctor will find a blockage in your heart's arteries (A) using cardiac catheterization techniques. A balloon on the tip of the catheter is inflated to widen the blocked artery, and a metal mesh stent is placed (B). After the stent is placed, the artery is held open by the stent, which allows blood to flow through the previously blocked artery (C).
