... Mitral regurgitation involves blood flowing back from the left ventricle into the left atrium during systole. Often, edges of mitral valve leaflets do not close completely during systole because leaflets and chordae tendineae have thickened and fibrosed, resulting in their contraction. The most comm ...

... Heart valve disease is the term used for a number of conditions that affect the four valves of the heart. A heart valve disease happens when any of the heart's valves either cannot open well enough to let blood flow through (stenosis) or cannot close well enough to prevent backflow of the blood (reg ...

Systole The atrioventricular valves (AV), the mitral and tricuspid valves close as the right and left ventricles contract to forcefully propel blood out of the heart to the lungs via the pulmonary artery (right ventricle) and to the body via the aorta (left ventricle).

Pericardial heart valves

The pericardial heart valve was invented by Marian Ionescu, a British surgeon working at the General Infirmary in Leeds, England. He created this artificial bioprosthetic heart valve as a three-cusp structure made of chemically treated bovine pericardium attached to a Dacron cloth-covered titanium frame.
