can mitral valve prolapse be inherited?
233187
Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse is also seen with some connective tissue disorders such as Marfan syndrome and other rare genetic disorders.

The genetic risk for HCM is passed from one generation to the next by way of dominant-acting mutations in genes governing the structure of the heart muscle. That means that first-degree relatives (parents, siblings, and children) of an affected person have a 50% chance of having inherited the same mutation.

Is mitral valve prolapse dangerous? In most cases, it's harmless. Most people who have the condition are unaware of it and their health isn't affected. However, in some cases treatment is required.

Antibiotic prophylaxis is no longer indicated in patients with mitral valve prolapse for prevention of infective endocarditis. The risk of antibiotic-associated adverse effects exceeds the benefit (if any) from prophylactic antibiotic therapy.

The mitral valve prolapse (MVP) syndrome has a strong hereditary tendency, although the exact cause is unknown. Affected family members are often tall, thin, with long arms and fingers, and straight backs. Mitral valve prolapse is more common in women from 20 to 40 years old; however, also occurs in men.

The symptoms associated with mitral valve prolapse may come and go over time, or they may disappear completely. There is a higher risk of stroke and the development of arrhythmias for these patients than in the general population.

Mitral valve prolapse is most often caused by idiopathic myxomatous degeneration of the mitral valve and chordae tendineae. Mitral regurgitation (MR) is the most common complication. Heart sounds often include a sharp, mid-systolic click that occurs earlier with the Valsalva maneuver.

But in some people with mitral valve prolapse, one or both of the mitral valve leaflets have extra tissue or stretch more than normal, which causes them to bulge like a parachute into the left atrium each time the heart contracts. The bulging may keep the valve from closing tightly.

Unlike angina and chest pain, rarely, mitral valve prolapse occurs during or after exercise,and may not respond to nitroglycerin. Anxiety, panic attacks, and depression may be associated with mitral valve prolapse. Like fatigue, these symptoms are believed to be related to imbalances of the autonomic nervous system.

Life expectancy for people with mitral valve prolapse usually is normal, which includes young people that require surgery. People that develop complications from the condition or have other medical problems may have a reduced life expectancy related to the complication.

Mitral valve prolapse (MVP) – also known as Barlow's syndrome, click-murmur syndrome, or floppy valve syndrome – is a condition in which the heart's mitral valve does not open and close properly. The most common heart valve abnormality, mitral valve prolapse is usually benign.

Infections or the inflammation they cause can damage the mitral valve. Congenital heart disease. Some people are born with an abnormal mitral valve prone to regurgitation. Age.

Living With. Most people who have mitral valve prolapse (MVP) have no symptoms or related problems, do not need treatment, and are able to lead normal, active lives. If symptoms and complications do occur, most often you can control them with medicines.

Symptoms of Mitral Valve Prolapse Chest pain is the most frequent symptom in people who have symptoms with mitral valve prolapse. The chest pain may be very bothersome and frightening, but it does not increase the risk of heart attack, death, or other heart problems.

Some forms of physical activity may not be safe with a prolapsed mitral valve and can actually worsen the condition. Engaging in the wrong types of exercise can trigger and aggravate MVP symptoms. In addition, complications can develop when there is repeated strain on the heart and its structures.

There's no clinical evidence that it can. A prolapsing mitral valve cannot cure naturally, and a leaking bicuspid heart valve cannot heal itself if you have the affliction. In mitral valve prolapse, irregular mitral valve leaflets prolapse and do not shut properly.

Tests physicians use to diagnose mitral valve prolapse include: Electrocardiogram (EKG/ECG) – A test that records the electrical activity of the heart. Echocardiogram (also called echo) – This test uses sound waves to assess the function and structure of the heart muscle and valves.
