What is myxomatous degenerative disease?
Myxomatous degeneration is a progressive, non-inflammatory disarray of the structure involved caused by a defect in the integrity of the structure, due to the alteration in the synthesis and remodelling of the tissue. Myxomatous is a term derived from the word Myxoma.
What is Myxomatous degeneration of the mitral valve?
A normal mitral valve is thin and supple and is anchored in place by strands of tissue called chordae tendinae. Myxomatous degeneration occurs when the valve becomes thickened. This prevents complete closure of the valve allowing blood to flow backward into the left atrium. This backflow is called mitral regurgitation.
What is the most common cause of mitral valve prolapse?
Mitral valve prolapse (MVP) is a billowing of mitral valve leaflets into the left atrium during systole. The most common cause is idiopathic myxomatous degeneration. MVP is usually benign, but complications include mitral regurgitation, endocarditis, and chordal rupture.
What is myxoid degeneration of aortic valve?
Myxoid degeneration is a rare cause of acute aortic valve regurgitation in a younger age group. 1 Diagnosis was initially uncertain as our patient did not have any history of trauma, infective endocarditis, rheumatic fever, syphilis or bicuspid aortic valve.
Is Myxomatous degeneration hereditary?
Many cases of myxomatous degeneration of the mitral valve are familial with a dominant inheritance. A genetic abnormality, mapped to Xq28, has been reported in one cohort but not yet in others [57].
What is the most common genetic cardiac disorder?
HCM remains the most common cardiovascular genetic disorder, occurring in at least 1 in 500 people in the general population. HCM is a primary inherited disorder of the myocardium characterized by hypertrophy, usually of the left ventricle, in the absence of other loading conditions such as hypertension.
