Stent placement, also known as coronary stenting, is a minimally invasive procedure used to treat narrowed or blocked coronary arteries. During the procedure, a small, expandable mesh tube called a stent is inserted into the affected artery to restore blood flow. The stent is delivered to the narrowed area using a catheter, which is typically inserted through the wrist or groin and threaded to the heart. Once in position, the stent is expanded, acting as a scaffold to keep the artery open. This helps alleviate symptoms such as chest pain and reduces the risk of heart attacks by improving blood flow to the heart muscle. Stents can be either bare metal or drug-eluting, which release medication to further prevent the artery from narrowing. Stent placement is a widely performed procedure that has revolutionized the treatment of coronary artery disease, offering a less invasive alternative to traditional open-heart surgery and enabling patients to recover more quickly.
