• A coronary heart incorporates 4 valves (tricuspid, pulmonary, mitral and aortic valves) which open and close as blood passes thru the heart. Blood enters the coronary heart inside the right atrium and passes through the tricuspid valve to the right ventricle. From there, blood is pumped through the pulmonary valve to go into the lungs. After being oxygenated, blood passes to the left atrium, in which is it pumped through the mitral valve to the left ventricle. The left ventricle pumps blood to the aorta thru the aortic valve.

• There are many ability causes of coronary heart valve damage, consisting of beginning defects, age related adjustments, and outcomes from different disorders, which include rheumatic fever and infections causing endocarditis. High blood pressure and coronary heart failure that may expand the heart and arteries, and scar tissue can shape after a coronary heart assault or harm.

• The 3 fundamental types of artificial heart valves are mechanical, biological (bioprosthetic/tissue), and tissue-engineered valves. In america, UK and the European Union, the most commonplace type of synthetic heart valve is the bioprosthetic valve. Mechanical valves are more normally utilized in Asia and Latin America. Companies that manufacture coronary heart valves encompass Edwards Lifesciences, Medtronic, Abbott (St. Jude Medical), CryoLife, and LifeNet Health.
