What causes mitral valve thickening

summary

The importance of mitral valve in the heart is self-evident, but there are many factors that cause heart valve disease. All kinds of inflammation, trauma and other reasons may lead to heart valve insufficiency. Moreover, the incidence of heart valve disease tends to be younger and younger, most of them are young adults aged 20-40, and many patients have a history of wind heat. Here is a detailed introduction to the causes of mitral valve thickening.

What causes mitral valve thickening

First: rheumatic fever caused by valvular disease, namely rheumatic heart disease, is an autoimmune disease secondary to Streptococcus infection, mainly causing progressive fibrosis, thickening, and even calcification of the valve.

Second: infective endocarditis, common in bacterial and fungal infections, mainly causes valve perforation, tear, and even damage.

Third: ischemic heart disease, more common after myocardial infarction, due to valve papillary muscle necrosis, or rupture, leading to mitral insufficiency.

matters needing attention

The most frequently involved valve was the mitral valve, followed by the aortic valve. Heart valve disease is characterized by structural damage, fibrosis, adhesion, shortening, myxomatous degeneration, ischemic necrosis, calcinosis or congenital malformation caused by inflammation of heart valve (including leaflet, chordae tendineae and papillary muscle). The most frequently involved valve was the mitral valve, followed by the aortic valve. The disease mostly occurs in the young and middle-aged people aged 20-40, of whom 2 / 3 are female, and most of them have a history of rheumatic fever. Here, only mitral and aortic valve diseases are described.
