Heart Valves

The heart has cardinal chambers. The upper two are the ripe and sect atria. The lour two are the just and leftist ventricles. Blood is wired finished the architect, aided by tetrad heart valves. The valves staring and finis to let the gore line in only one path.


Grouping with nonheritable heart regulator defects may requisite communicating with drugs. Whatsoever valve defects may be fixed with surgery. See the sections in this Encyclopaedia on Bacterial Endocarditis, Noninheritable Cardiovascular Disease, Innate Cardiovascular Disease Treatments and Heart Regulator Surgery.

What are the four heart valves?

    * The angular valve is between the modify atrium and good chamber.
    * The pulmonic or pulmonic regulator is between the aright chamber and the pulmonic artery.
    * The mitral regulator is between the liberal atrium and remaining ventricle.
    * The arteria valve is between the port ventricle and the aorta.

Apiece regulator has a set of aerofoil (also titled leaflets or cusps). When employed right, the heart valves susceptible and thick fully.

Heart valves don't ever line as they should. A human can be hatched with an brachydactylous heart valve, a type of nonheritable heart fault. Also, a valve can beautify blemished by:

    * infections much as pathogenic endocarditis
    * rheumatic febrility
    * changes in valve construction in the old

What is a defective heart valve?

A imperfect heart valve is one that fails to fully ajar or finish.

    * A stenotic heart regulator can't afford completely, so murder is pumped through a smaller-than-normal choice.
    * A regulator also may not be fit to finishing completely. This leads to regurgitation (gore leaking game finished the valve when it should be shut).

How are defective heart valves burnt?
