Echocardiography can quantify heart functioning by measuring, for example, enlargement of the left ventricle, the ejection fraction, and the situation of the heart valves. The most accurate ways to detect CAD are the coronary angiogram and the coronary CT angiography. [4] An angiogram can provide detailed anatomy of coronary circulation and ...
The first stent was patented in 1972 by Robert A. Ersek, MD based on work he had done in animals in 1969 at the University of Minnesota. In addition to intervascular stents, he also developed the first stent-supported porcine valve that can be implanted transcutaneously in 7 minutes, eliminating open-heart surgery. [37]
Off-pump coronary artery bypass (OPCAB), or beating-heart surgery, is a form of coronary artery bypass graft (CABG) surgery performed without cardiopulmonary bypass (heart-lung machine) as a treatment for coronary heart disease. It was primarily developed in the early 1990s by Dr. Amano Atsushi.
Tissue engineered heart valves (TEHV) offer a new and advancing proposed treatment of creating a living heart valve for people who are in need of either a full or partial heart valve replacement. Currently, there are over a quarter of a million prosthetic heart valves implanted annually, [ 1 ] and the number of patients requiring replacement ...
Dr. Davis emphasizes that valve damage is not only caused by poor dietary habits, explaining, “Diet is often talked about in connection to heart disease, but valve damage has different causes.
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
Valve interstitial cells (VIC), cardiac valve interstitial cells, or also known as valvular interstitial cells (VICs), are the most prevalent cells in the heart valve leaflets, which are a type of mesenchymal stem cells (MSCs) and are responsible for maintaining the extracellular matrix that provides the mechanical properties of the heart valve.
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 ...
