Catheterization stent bare metal-PTCA using bare metal stents | Brandenburg Heart Center

In this editorial, we provide an overview of the development of coronary stents since their introduction in the late s, with special focus on currently available stents and bioresorbable scaffolds.. One year later, they intentionally used a catheter for the first successful percutaneous transluminal peripheral angioplasty. Plain old balloon angioplasty can transiently achieve a larger luminal diameter by plaque extrusion, but elastic recoil rapidly obliterates this gain. Abrupt occlusion obliged the pioneers of coronary angioplasty to have an active surgical stand-by during these procedures. The balloon induced intimal denudation and medial tearing exposed subendothelial matrix to blood, promoting platelet aggregation and thrombosis in the acute phase and chronic negative vascular remodeling late recoil and neointimal hyperplasia.

We defined Catheterization stent bare metal restenosis as any within stent or stent edge restenosis as previously established by Mehran and colleagues The focus of stent technologies in is on bioresorbable polymers to make metallic stents into bare metal stents after a few months of being implanted. Abbott makes the Xience stent used in the trial, which compared equally with long-term CABG surgical outcomes.

The stent is usually inserted in the artery once it is widened by the inflated balloon. The stent supports the walls of the artery to help prevent it from re-narrowing after the angioplasty. Source : Mayoclinic , NIH.

Stents are small expandable tubes used to treat narrowed or weakened arteries in the body. In patients with coronary artery disease CAD , stents are used to open narrowed arteries and help reduce symptoms such as chest pain angina or to help treat a heart attack. These types of stents are commonly called heart stents, but they are also referred to as cardiac or coronary stents.

Usually made of metal mesh, heart stents are implanted in narrowed coronary arteries during a procedure called a percutaneous coronary intervention PCI or angioplasty. Stents help prevent the artery from becoming blocked again restenosis.

It is a first-of-its-kind stent therapy designed to not only reduce the likelihood of the re-narrowing of the artery or of having to undergo a repeat procedure, but also help the healing process of the artery. It combines the benefit of DES and bio-engineered stents and is the only stent to contain a drug with active healing technology. The DTS has coating both inside and outside, which reduces the likelihood of blood clots, inflammation and helps the healing process of the artery.

The stent surface facing the artery wall contains a drug that is released to help stop the artery blocking again without the worry of swelling or an inflammatory response. The drug is delivered from a bioresorbable polymer that will degrade over time.

The side of the stent which faces blood flow is coated with antibodies, which promote natural healing and helps the healthy artery function properly. The Bio-Vascular Scaffold BVS is a drug eluting stent on a dissolvable type of scaffold platform which can be absorbed by the body over time.

Like some of the currently available Drug Eluting Stents DES , BVS is coated with a drug released from a polymer that disappears over time to reduce the likelihood of the artery re-narrowing restenosis. The scaffold itself is absorbed overtime. Unlike with the DTS, there is no active element to promote artery healing. Bio-engineered Stent is also known as antibody-coated stent. This type of stent differs from DES because it does not contain a polymer and does not use a drug. As a result, it helps to speed up the cell lining of the artery endothelialization , promoting natural healing.

The antibody on the stent's surface attracts circulating Endothelial Progenitor Cells EPCs which come from human bone marrow and help speed up the formation of healthy endothelium. This provides rapid coverage over the stent's surface helping to reduce the risk of early and late thrombosis blood clots.

Drug Eluting Stents DES are coated with medication that is released eluted to help prevent the growth of scar tissue in the artery lining. This helps the artery remain smooth and open, ensuring good blood flow and reduces the chances of the artery re-narrowing or restenosis. However, it also leads to a higher chance of blood clots stent thrombosis.

Due to a relatively slower healing process, patients implanted with DES must strictly follow their doctor's recommendation on drug therapy DAPT to help reduce risk of stent thrombosis. Bare metal stents are usually stainless steel and have no special coating.

They act as scaffolding to prop open blood vessels after they are widened with angioplasty. As the artery heals, tissue grows around the stent, holding it in place. However, sometimes an overgrowth of scar tissue in the arterial lining increases the risk of re-blockage. Source : Patient. Arteriosclerosis, Thrombosis, and Vascular Biology.

Here's what happens: The stent, which is mounted on a balloon at the tip of the catheter, is guided through the artery to the blockage.

At the blockage, the balloon is inflated and the stent expands and locks into place inside the artery. The stent stays in the artery permanently to hold it open and improve blood flow to the heart.

Percutaneous transluminal coronary angioplasty PTCA is used to treat coronary artery stenosis. The use of bare metal stents is mainly reserved for large blood vessels, or when the patient is already receiving anticoagulants for a separate condition.

A patient with coronary artery stenosis may have a stent implanted during cardiac catheterization. When compared to simple balloon angioplasty, stent treatment reduces the risk of restenosis occurring at a previously treated site. Stents may be drug-eluting or bare metal, i. Not only are bare metal stents associated with quicker tissue healing, but patients receiving this type of stent also only require dual antiplatelet therapy for a duration of one month following implantation.

As a result, this type of stent may be used in patients who are scheduled to undergo surgery, or in patients who are already receiving anticoagulant medication for a different condition. Stents were developed as a result of advances in the field of balloon angioplasty, and were intended to address two specific problems that can occur during or after a simple balloon angioplasty procedure. Although these tears are usually only partial, i. Prior to the introduction of stent technology, larger tears often resulted in the patient requiring emergency bypass surgery, whereas stents can now be used to support the vessel wall from the inside.

This re-establishes normal blood flow and avoids the need for emergency surgery. Another problem typically associated with balloon angioplasty is restenosis of a section previously widened using balloon angioplasty.

Sigwart et al. A PTCA procedure is performed in order to treat coronary artery stenosis, and to alleviate the symptoms of angina pectoris associated with physical exertion. It is possible for patients with diabetes to remain asymptomatic despite clear evidence of a disruption in the normal flow of blood.

This may be due to specific nerve damage typically found in patients with diabetes. Depending on the nature of the patient's concomitant disease, and the characteristics of the stenosis, measures to prevent restenosis in the months following treatment may involve bare metal or drug-eluting stents. All patients will require long-term drug-based treatment to prevent or slow the progression of vascular disease in untreated vessels.

All patients who undergo stent treatment will be required to take anticoagulant medication in order to prevent the treated vessel from becoming blocked. Patients who undergo stent treatment using bare metal stents usually only require two antiplatelet drugs dual therapy , and only for a duration of one month.
