2023年11月7日 · Coronary artery stent. To place a coronary artery stent, a balloon on the tip of the catheter is inflated to widen the blocked artery (A). Then a metal mesh stent is placed (B). The stent helps hold the artery open so blood can flow through it (C).

A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).

2023年3月15日 · A stent is a tiny wire mesh tube that keeps an artery propped open to increase blood flow to the heart. When plaque builds up in a coronary artery (which feeds the heart muscle), it can narrow the artery, which may reduce blood flow …

Stents. Coronary stents are now used in nearly all angioplasty procedures. A stent is a tiny, expandable metal mesh coil. It's put into the newly opened area of the artery to help keep the artery from narrowing or closing again. Tissue will start to coat the stent like a layer of skin once the stent has been placed.

2019年3月22日 · Cardiac stents are expandable coils made of metal mesh. Your doctor can insert one during a coronary angioplasty, a nonsurgical and minimally invasive procedure. The device is designed to...

2023年8月7日 · Coronary stents (CS) are expandable tubular metallic devices which are introduced into the coronary arteries that demonstrate stenosis due to an underlying atherosclerosis disease. This revascularization procedure is termed as a percutaneous coronary intervention (PCI) or coronary angioplasty with stent placement.

What Is a Stent? A stent is a tiny wire mesh tube that keeps a coronary artery open to increase blood flow to the heart. This reduces the chance of a heart attack. Coronary arteries (arteries feeding the heart muscle) can become narrowed by a buildup of fatty deposits called plaque.

2024年8月3日 · In people with coronary heart disease caused by the buildup of plaque, they can: These types are called coronary stents. Usually made of metal mesh, they’re put into arteries after a...

2023年6月5日 · Describe the role of coronary artery stents in the management of coronary artery disease. Explain the anatomical characteristics of coronary artery stents. Outline the clinical significance and possible complications associated with coronary artery stent placement.

冠状动脉支架（coronary stent）是置于冠状动脉中长数毫米的网型管柱支架，长度与直径规格依病况需求选用；支架的目的是使冠状动脉保持畅通以提供心脏足够血流。
