A coronary stent placed by percutaneous coronary intervention. Older bare-metal stents (BMS) provide a mechanical framework that holds the artery wall open, preventing stenosis, or narrowing, of coronary arteries. Newer drug-eluting stents (DES) are traditional stents with a polymer coating containing drugs that prevent cell proliferation. The ...
Bare metal stents were found to cause in-stent restenosis as a result of neointimal hyperplasia and stent thrombosis, which led to the invention of drug-eluting stents with anti-proliferative drugs to combat in-stent restenosis. [1] The first coronary angioplasty with a drug delivery stent system was performed by Stertzer and Luis de la Fuente ...
Coronary artery stents, typically a metal framework, can be placed inside the artery to help keep it open. However, as the stent is a foreign object (not native to the body), it incites an immune response. This may cause scar tissue (cell proliferation) to rapidly grow over the stent and cause a neointimal hyperplasia.
Coronary angiography and angioplasty in acute myocardial infarction (left: Right Coronary Artery [RCA] closed, right: successfully dilated) Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases.
Vascular stents are commonly used in angioplasty, a surgical procedure that opens blocked arteries and places a stent to keep the artery open. This is a common treatment for heart attacks and is also used in the prevention and treatment of strokes. Over 2 million people receive a stent each year for coronary artery disease alone.
The angioplasty uses the insertion of a balloon and/or stents to open up the artery. [1] Other surgeries performed are the more invasive bypass surgeries that graft arteries around blockages. If an MI is presented with ECG evidence of an ST elevation known as STEMI , or if a bundle branch block is similarly presented, then reperfusion therapy ...
Current clinical uses of IVUS technology include checking how to treat complex lesions before angioplasty and checking how well an intracoronary stent has been deployed within a coronary artery after angioplasty. If a stent is not expanded flush against the wall of the vessel, turbulent flow may occur between the stent and the wall of the ...
Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel through the healing process. However, in the case of a bioresorbable stent, the stent will gradually resorb and be benignly cleared from the body, enabling a natural reconstruction of the arterial wall and restoration of vascular function.
