Mitral Valve Prolapse Symptoms In addition, some patients with mitral valve prolapse will have irregular heart rhythms that cause palpitations, or in worse cases, may even cause fainting or passing out.

Signs and symptoms of mitral valve regurgitation, which depend on its severity and how quickly the condition develops, can include: Abnormal heart sound (heart murmur) heard through a stethoscope. Shortness of breath (dyspnea), especially when you have been very active or when you lie down. Fatigue.

Mitral valve regurgitation is understood to cause pulmonary edema as a result of increased intravascular hydrostatic pressure. Previous studies have shown that predominantly right upper lobe edema may be caused by a directed regurgitant jet with resultant local increases in hydrostatic pressure.

Unlike angina, chest pain with mitral valve prolapse rarely 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.

Most mitral insufficiency with mitral valve prolapse is mild. Though Mitral Valve Prolapse is usually not serious, it may be accompanied by various minor symptoms, such as shortness of breath, tiredness, heart palpitations, chest pains, dizziness, headaches, and insomnia.

The lack of blood to the brain causes loss of consciousness. Most fainting will pass quickly and won't be serious. Usually, a fainting episode will only last a few seconds, although it will make the person feel unwell and recovery may take several minutes.

It may cause fainting or serious side effects in some patients. Contact your doctor right away if your symptoms do not improve or if they get worse. Check with your doctor right away if you develop any of the following: chest pain, shortness of breath, swelling of your hands, ankles, or feet, or weight gain.

They may be bothersome, but aren't usually life-threatening. People with severe mitral valve regurgitation or severe deformity of their mitral valve are most at risk of having rhythm problems, which can affect blood flow through the heart. Heart valve infection (endocarditis).

You can faint if your brain isn't receiving enough oxygen. This most often happens due to a sudden drop in blood pressure. Prior to fainting, a person may experience feelings of dizziness or lightheadedness. In some cases, sweating may also occur.

Blocked blood flow. In many people, the thickened heart muscle blocks the blood flow leaving the heart, causing shortness of breath with exertion, chest pain, dizziness and fainting spells.

The physiologic consequences of mitral regurgitation include reduced forward stroke volume; increased left atrial volume and pressure; and reduced resistance to left ventricular ejection.

So if you suddenly start experiencing fainting spells and you have no history of fainting, you should see your doctor. You should be especially concerned if you faint while exercising as it can be a sign of a heart disorder. If you do experience a fainting episode, remember not to stand up until you feel better.

Rarely, a mitral prolapse may even cause sudden death. Classic MVP is the type of mitral prolapse most likely to cause deadly complications, particularly when leaflet displacement is flail and asymmetric. This type usually accompanies disturbing mitral valve prolapse symptoms.

It's also called fainting or "passing out." It most often occurs when blood pressure is too low (hypotension) and the heart doesn't pump enough oxygen to the brain. It can be benign or a symptom of an underlying medical condition.

However, in the most serious cases it can cause abnormal heartbeats (arrhythmias) that may eventually become life-threatening. When mitral valve prolapse is severe enough to cause significant valve leakage, called “regurgitation,” it can lead to serious complications such as heart attack and stroke.

More severe mitral valve regurgitation can cause symptoms such as shortness of breath, fatigue or lightheadedness. Another name for mitral valve prolapse is click-murmur syndrome.

Fainting usually is caused by a temporary drop in blood pressure. During that brief drop, the brain does not get the blood flow that it needs—and you lose consciousness.
