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 .
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.
Catheter replacement of the aortic valve (called trans-aortic valve replacement or implementation [TAVR or TAVI]) is a minimally invasive option for those suffering from aortic valve stenosis. TAVR is commonly performed by guiding a catheter from the groin to the narrowed valve via the aorta using realtime x-ray technology.
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 ...
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").
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 ...

Minimally invasive cardiac surgery, encompasses various aspects of cardiac surgical procedures (aortic valve replacement, mitral valve repair, coronary artery bypass surgery, ascending aorta or aortic root surgery) that can be performed with minimally invasive approach either via mini-thoracotomy or mini-sternotomy.
