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).
The valve is repositionable before release to ensure accurate placement helping to improve patient outcomes. [12] Edwards' Sapien aortic valve is made from bovine pericardial tissue and is implanted via a catheter-based delivery system. It is approved by the FDA for use in the US. [10] [11] [12]
Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...
Postpericardiotomy syndrome (PPS) is an immune phenomenon that occurs days to months (usually 1–6 weeks [1]) after surgical incision of the pericardium (membranes encapsulating the human heart). [2] PPS can also be caused after a trauma, a puncture of the cardiac or pleural structures (such as a bullet or stab wound), after percutaneous ...
After placement of a stent or scaffold, the patient needs to take two antiplatelet medications (aspirin and one of a few other options) for several months to help prevent blood clots. The length of time a patient needs to be on dual antiplatelet therapy is individualized based risks of ischemic events and bleeding risk.
Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis .
Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of an aortic aneurysm, less frequently for congenital aortic stenosis. [53]
A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
