Mitral Valve aka Bicuspid Valve
Human Anatomy & Physiology II

The left atrioventricular valve, with two cusps, is called the mitral valve because it resembles the two-sided bishops miter or hat. It is sometimes called the biscuspid valve. (Marieb & Hoehn, 2007). This valve separates the left atrium of the heart from the left ventricle of the heart. It prevents the back flow of oxygenated blood to the pulmonary circuit. Heart valves are simple devices, and the heart – like any mechanical pump – can function with “leaky” valves as long as the impairment is not too great. However, severe valve deformities can seriously hamper cardiac function. (Marieb & Hoehn, 2007). The mitral valve (bicuspid valve) can be replaced successfully by means of surgical intervention. New research is being developed to engineer tissue grown from the patient’s own cells to replace the defective mitral valve. Barik, Ramachandra, Patnaik, A.N.,Mishra, Ramesh C., Kumari, N.

Heart surgery of any sort is a delicate procedure. This procedure was performed for multiple disorders of the heart and circulation. The patient presented with a combination of both congenital and acquired cardiac defects. The diagnosis included congenital bicuspid aortic valve, aortic regurgitation juxta-subclavian coarctation, stenosis of the left subclavian artery and ruptured sinus of the valsalva aneurysm. This combination of defects is very rare. The patient was weakened by the severity of the defects and the multiple disorders. It was decided to perform the corrective procedure in one surgery. The surgery was performed for this patient without complications. Management of this type of cardiac

    Heart valve replacements are more common than most people think. In the United States it is said that over 99,000 heart valve surgeries are performed yearly. The majority of the valve replacement surgeries are to replace or repair the mitral or aortic valve, since the left side of the heart works harder than the right. There are several types of valve disease, the two most common are valvular stenosis and valvular insufficiency. Valvular stenosis occurs when the opening of the valve is smaller…

    Mitral Valve Prolapse Human Anatomy and Physiology II Kristen Ammen The mitral valve is located on the left side of the heart between the left atrium and left ventricle. The purpose of the mitral valve is to form a seal between these two chambers of the heart to prevent the back flow of blood. When blood enters the left side of the heart, it is oxygenated and enters through the pulmonary veins. The blood then travels through the left atrium; the bicuspid (mitral) valve then opens to let the…

    MITRAL VALVE DISEASE MITRAL STENOSIS Mitral stenosis is almost always rheumatic in origin, although in the elderly it can be caused by heavy calcification of the mitral valve apparatus. There is also a rare form of congenital mitral stenosis. In rheumatic mitral stenosis, the mitral valve orifice is slowly diminished by progressive fibrosis, calcification of the valve leaflets, and fusion of the cusps and subvalvular apparatus. The flow of blood from left atrium to left ventricle…

    most common is a mitral heart prolapse. More of a defect than a disease, but equally as troublesome, mitral heart prolapse afflicts as many as 8 million people in the United States alone. Essentially it is a faulty heart valve, particularly the mitral valve (hence the name). Because of this valve’s malfunction, when the heart normally contracts to pump blood through the body, the mitral valve slips back into place too fragile. In direct opposition to this condition is mitral valve stenosis that is…

    6. The Mitral valve or tricuspid valve is leaking. The sloshy sound will be heard during the atrial systole. The dub is heard during the ventricular diastole. The chordae tendinae, or heart strings, support the atrioventricular valve because the heart strings connects the papillary muscles to the tricuspid and mitral valve. 7.

    Aortic Valve Stenosis Aortic Valve Stenosis is the narrowing or obstruction of the heart 's aortic valve. The aorta is a large artery that originates in the left ventricle (lower chamber) of the heart. The narrowing and obstruction of the aortic valve prevents it from opening properly and blocks the flow of blood from the left ventricle to the aorta and onward towards the rest of the body. Aortic valve stenosis occurs in approximately 5 out of every 10,000 people.1 It occurs more commonly…
