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 ...
As with any procedure involving the heart, complications can sometimes, though rarely, cause death. The mortality rate during angioplasty is 1.2%. [17] Sometimes chest pain can occur during angioplasty because the balloon briefly blocks off the blood supply to the heart. The risk of complications is higher in: [18] People aged 65 and older
The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...
The heart is typically reached by passing through the femoral vein, jugular vein, or subclavian vein. [4] A balloon dilation test is performed first, to confirm that coronary compression will not occur and the procedure can continue. [4] [6] Stent fractures can be prevented by using pre-stenting, using a bare metal stent before TPVR. [5]
A hybrid cardiac surgical procedure in a narrow sense is defined as a procedure that combines a conventional, more invasive surgical part (including a skin incision) with an interventional part, using some sort of catheter-based procedure guided by fluoroscopy (or other, e.g., CT or MRI) imaging in a hybrid operating room (OR) without interruption. [1]
Rates of restenosis differ between devices (e.g., stent-grafts, balloon angioplasty, etc.) and location of procedure (i.e., centrally located in the heart, such as the coronary artery, or in peripheral vessels such as the popliteal artery in the leg, the pudendal artery in the pelvis, or the carotid artery in the neck).

Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...
The WCD allows physicians time to assess their patient's cardiac arrhythmic risk, make appropriate treatment plans and monitor cardiac output before or after an invasive cardiac procedure (such as bypass surgery, stent placement or heart transplant) or in patients at high risk for SCD after myocardial infarction (MI).
