Because there is much more pressure on the mitral valve.
Mitral valve prolapse occur more often than tricuspid valve prolapses because the mitral valve is attached to the left ventricle by two chordae tendinae, whereas the tricuspid valve adheres to the right ventricle via three chordae tendinae. Thus, the tricuspid valve has more stability and is less likely to prolapse.

Can you get a cramp in the heart?
Definition Mitral valve prolapse (MVP) is a common heart disorder. It occurs when the valve between your heart's left upper chamber (left atrium) and the left lower chamber (left ventricle) doesn't close properly. When the left ventricle contracts, the valve's leaflets bulge (prolapse) upward or back into the atrium. Mitral valve prolapse sometimes leads to blood leaking backward into the left atrium, a condition called mitral valve regurgitation. Mitral valve prolapse affects slightly more than 2 percent of adults in the United States. Men and women appear to develop MVP in similar numbers. In most people, mitral valve prolapse is harmless and doesn't require treatment or changes in lifestyle. It also doesn't shorten your life expectancy. In some people with mitral valve prolapse, however, the progression of the disease requires treatment. Symptoms Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease What that feeling is is called a something-valve prolapse or something. My dad and I get them ocassionally. It is where a valve doesnt close right. Its harmless and the best way to get rid of it is to breath it out or wait it out.
What causes mitral valve insufficiency?
MVP (mitral valve prolapse) is generally considered to be present at birth, although quite often it isn't diagnosed until one's twenties. Usually MVP is not extremely dangerous; very rarely, it has caused sudden death by cardiac arrest. Some people with MVP take medications such as Metoprolol to regulate their heart rate; others use pacemakers. A third option, less often used, is to implant a defibrillator that only activates if a life-threatening cardiac arrhythmia occurs. MVP is a mild to moderate problem with a valve that causes a slight heart murmur. It is most common in white females who are slightly underweight, but can happen in anyone.
What is the valve that is between the ventricles and their arteries?
Between the Atria and Ventricles of the heart are the aptly named Atrioventricular valves. The valve between the right atrium and ventricle is called the Tricuspid because id has three Cusps (of small flaps the are pushed together and closed when under pressure). The valve between the left atrium and ventricle is called the Bicuspid because it has two cusps, of more often called the Mitral Valve because its two cusps look like a bishops hat.
Earthquakes occur most often along the?
Earthquakes occur most often along the boundaries of tectonic plates.
What do earthquakes often occur along?
The edge of the oceanic and continental plates.
Mitral valve prolapse allows blood to enter where?
Mitral valve prolapse allows blood to enter into the left atrium. This often results in the valve not forming a tight seal.

Mitral valve prolapse?
DefinitionMitral valve prolapse is a heart problem in which the valve that separates the upper and lower chambers of the left side of the heart does not close properly.Alternative NamesBarlow syndrome; Floppy mitral valve; Myxomatous mitral valve; Billowing mitral valve; Systolic click-murmur syndrome; Prolapsing mitral leaflet syndromeCauses, incidence, and risk factorsThe mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts).Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. In most cases, it is harmless and patients usually do not know they have the problem. As much as 10% of the population has some minor, insignificant form of mitral valve prolapse, but it does not generally affect their lifestyle.In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation.Mitral valves that are structurally abnormal can raise the risk for bacterial infection.Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with Graves disease.Mitral valve prolapse often affects thin women who may have minor chest wall deformities, scoliosis, or other disorders.Mitral valve prolapse is associated with some connective tissue disorders, especially Marfan syndrome. Other conditions include:Ehlers-Danlos syndromeOsteogenesis imperfectaPolycystic kidney diseaseSymptomsMany patients with mitral valve prolapse do not have symptoms. The group of symptoms found in patients with mitral valve prolapse is called "mitral valve prolapse syndrome" and includes:Sensation of feeling the heart beat (palpitations)Chest pain (not caused by coronary artery disease or a heart attack)Difficulty breathing after activityFatigueCoughShortness of breath when lying flat (orthopnea)Note: There may be no symptoms, or symptoms may develop slowly.Signs and testsThe doctor will perform a physical exam and use a stethoscope to listen to your heart and lungs. The doctor may feel a thrill (vibration) over the heart, and hear a heart murmur ("midsystolic click"). The murmur gets louder when you stand up.Blood pressure is usually normal.The following tests may be used to diagnose mitral valve prolapse or a leaky mitral valve:EchocardiogramColor-flow Doppler examinationCardiac catheterizationChest x-rayECG (may show arrhythmias such as atrial fibrillation)Chest MRICT scan of the chestTreatmentMost of the time, there are no (or few) symptoms, and treatment is not needed.If you have severe mitral valve prolapse, you may need to stay in the hospital. You may need surgery to repair or replace the valve if you have severe mitral regurgitation or your symptoms get worse. Mitral valve replacement may be needed if:You have symptomsThe left ventricle of the heart is enlargedHeart function gets worse (depressed ejection fraction)In the past, some people with mitral valve prolapse were given antibiotics before certain dental or surgical procedures to help prevent an infection called bacterial endocarditis (BE). However, the American Heart Association no longer recommends routine antibiotics before dental procedures or other surgical procedures for patients with only mitral valve prolapse, unless they have had bacterial endocarditis in the past.Other drugs that may be prescribed when mitral regurgitation or other heart problems are also present:Anti-arrhythmic drugs help control irregular heartbeats.Water pills (diuretics) help remove excess fluid in the lungs.Propranolol is given for palpitations or chest pain.Blood thinners (anticoagulants) help prevent blood clots in people who also have atrial fibrillation.Expectations (prognosis)Mitral valve prolapse should not negatively affect your lifestyle. If the leaky valve becomes severe, your outlook may be similar to that of people who have mitral regurgitation from any other cause.Most of the time, the condition is harmless and does not cause symptoms. Symptoms that do occur can be treated and controlled with medicine or surgery. However, some irregular heartbeats (arrhythmias) associated with mitral valve prolapse can be life-threatening.ComplicationsEndocarditis -- valve infectionSevere leaky mitral valve (regurgitation)StrokeClots to other areasIrregular heartbeat (arrhythmias), including atrial fibrillationCalling your health care providerCall your health care provider if you have:Chest discomfort, palpitations, or fainting spells that get worseLong-term illnesses with feversPreventionYou can't usually prevent mitral valve prolapse, but you can prevent certain complications. Tell your health care providers, including your dentist, if you have a history of heart disease or heart valve problems.ReferencesAmerican College of Cardiology/American Heart Association.

What does Mr severe means in echocardiogram?
An echocardiogram is an ultrasound of the heart. it is useful when looking at the function of the cardiac muscle as well as the cardiac valves. The mitral valve separates the left atrium from the ventricle. MR refers to Mitral Regurgitation which is when the valve becomes floppy from a number of causes including mitral valve prolapse, connective tissue disease, rheumatic heart disease or myocardial infarction and allows blood to flow from the left ventricle back into the left atrium during systole. Markers of severity on echocardiography include a regurgitant fraction of >50% or total volume > 60mls. Severe MR can result in progressive heart failure and often requires valve replacement surgery to correct.
