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). They are used in a medical procedure called percutaneous ...
A heart attack during or shortly after the procedure occurs in 0.3% of cases; this may require emergency coronary artery bypass surgery. [13] Heart muscle injury characterized by elevated levels of CK-MB, troponin I, and troponin T may occur in up to 30% of all PCI procedures. Elevated enzymes have been associated with later clinical outcomes ...
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.
The FDA recently approved a heart stent made specifically for infants and young children, a device that could help kids born with certain congenital heart defects avoid a series of open heart ...
A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
A stent graft or covered stent is type of vascular stent with a fabric coating that creates a contained tube but is expandable like a bare metal stent. Covered stents are used in endovascular surgical procedures such as endovascular aneurysm repair. Stent grafts are also used to treat stenoses in vascular grafts and fistulas used for hemodialysis.
A dual therapy stent is a coronary artery stent that combines the technology of an antibody-coated stent and a drug-eluting stent. [1] Currently, second-generation drug-eluting stents require long-term use of dual-antiplatelet therapy , which increases the risk of major bleeding occurrences in patients. [ 2 ]
Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart.This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").
