Is mitral valve prolapse hereditary?
Is mitral valve prolapse hereditary? Is mitral valve prolapse genetic? Is mitral valve prolapse congenital? Yes, to all of the above.
MVP has a strong hereditary tendency. Researchers have connected different loci on several human chromosomes with mitral valve prolapse. In addition, at least one specific gene (the DCSH1 gene) has been linked to the heart valve condition.
People often inherit mitral valve prolapse, especially MVP that occurs with symptoms of dysautonomia. However, not all cases of MVP are genetic. Sometimes, the condition develops for reasons that are not related to genes, such as when diseases or trauma damage components of the mitral valve.
How does MVP develop?
When asking, “Is mitral valve prolapse hereditary?” it’s important to know what MVP is and how it develops. The condition occurs when the leaflets of the mitral valve do not close properly during heart contractions, causing them to prolapse back into the left atrium. This may be due to thickening or enlargement of the leaflets or an abnormality of one or more mitral apparatus components.
Most people are born with normal mitral valves. Yet, there are those who are born with a mitral abnormality. In some cases, conditions are present from birth that physically alter the valve’s structure over time. Other times, diseases develop that damage the valve and cause a prolapse. Depending on the type of MVP and if there are symptoms and regurgitation, treatment may be necessary.
Treatment of mitral valve prolapse and mitral regurgitation involves surgery when severe. However, most of the time patients can manage MVP quite effectively with much less invasive treatments. A lot of people with a prolapsed mitral valve take beta blockers and benzodiazepine anxiety medication to help manage their MVP symptoms. Others prefer natural mitral valve prolapse treatments.
What are the mitral valve prolapse causes?
There are many possible causes. Adult polycystic kidney disease, pseudoxanthoma elasticum, and genetic connective tissue disorders such as Marfan’s syndrome, Ehlers-Danlos syndrome, and osteogenesis imperfecta may cause mitral valve prolapse. Researchers have also linked scoliosis, pectus excavatum, and Graves’ disease, as well as some muscular dystrophies, with MVP.
Other mitral valve prolapse causes include heart attacks and heart valve infections (infective endocarditis), diseases such as rheumatic fever (especially when it goes untreated), and congenital heart defects such as atrial septal defect and Ebstein’s anomaly. Myxomatous degeneration, which typically affects older individuals, can damage the mitral valve and cause it to prolapse.
Less commonly, medications are the cause of a mitral valve prolapse in the heart. The condition may develop with long-term use of certain medications that treat migraines, including ergotamine and methysergide. It may also develop when taking appetite suppressant drugs such as dexfenfluramine and fenfluramine. Pergolide (treats Parkinson’s) can produce a prolapse of the mitral valve.
Can mitral valve prolapse be cured?
Is there a cure for MVP? Unfortunately, it is not possible to restore the original condition and function of a damaged or defective mitral valve, nor can you install a new human valve that will work perfectly for life. That being said, mitral valve surgery can correct a prolapse, and there are many treatment options available to relieve the symptoms of mitral valve prolapse and dysautonomia.
In severe case of MVP, surgeons can repair the mitral valve and its structures. They can even replace the valve with an artificial valve when necessary. The prognosis is usually good with both options. Most patients reporting feeling significantly better after surgery. To relieve the symptoms of the condition, sufferers can take medication or opt for natural remedies for mitral valve prolapse.
Following a heart-healthy MVP diet can go a long way in relieving the symptoms of the mitral prolapse disorder. Exercising regularly has also shown to help patients who are symptomatic. Of course, one should also stay away from things to avoid with mitral valve prolapse. To conclude, can mitral valve prolapse be cured? For the most part. Is mitral valve prolapse hereditary? Yes, but not always.
