What You Need to Know

Mitral valve prolapse, likewise known as click-murmur syndrome, Barlow"s syndrome, balloon mitral valve, or floppy valve syndrome, is the bulging of one or both of the mitral valve flaps (leaflets) right into the left atrium throughout the contraction of the heart.

One or both of the flaps may not close effectively, allowing the blood to leak backward (regurgitation). Mitral regurgitation (backward flow of blood), if existing at all, is primarily mild

This regurgitation might bring about a murmur (abnormal sound in the heart due to stormy blood flow).

It is estimated that mitral valve prolapse occurs in about 3 percent of the populace.

What is the mitral valve?

The mitral valve is located between the left atrium and the left ventricle and is composed of two flaps. Usually the flaps are hosted tightly closed during left ventricular contraction (systole) by the chordae tendineae (little tendon "cords" that connect the flaps to the muscles of the heart). In Mitral Valve Prolapse, the flaps enlarge and also stretch inward towards the left atrium, occasionally "snapping" throughout systole, and may enable some backcirculation of blood right into the left atrium (regurgitation).

What causes Mitral Valve Prolapse?

The reason of Mitral Valve Prolapse is unknown, however is thshould be linked to heredity. Primary and second forms of Mitral Valve Prolapse are defined below.


Main Mitral Valve Prolapse. Main Mitral Valve Prolapse is distinguimelted by thickening of one or both valve flaps. Other effects are fibrosis (scarring) of the flap surchallenge, thinning or lengthening of the chordae tendineae, and fibrin deposits on the flaps. The main form of Mitral Valve Prolapse is seen commonly in people through Marfan"s Syndrome or various other inherited connective tconcern illness, but is the majority of often watched in human being with no other form of heart disease.

Secondary Mitral Valve Prolapse. In additional Mitral Valve Prolapse, the flaps are not thickened. The prolapse might be due to ischemic damages (resulted in by decreased blood flow as an outcome of coronary artery disease) to the papillary muscles attached to the chordae tendineae or to useful alters in the myocardium. Secondary Mitral Valve Prolapse may result from damage to valvular frameworks in the time of acute myocardial infarction, rheumatic heart illness, or hypertrophic cardiomyopathy (occurs once the muscle mass of the left ventricle of the heart is bigger than normal).

What are the symptoms of Mitral Valve Prolapse?

Mitral valve prolapse might not reason any symptoms. The adhering to are the most common symptoms of Mitral Valve Prolapse. However, each individual might suffer symptoms differently. Symptoms might differ relying on the level of prolapse present and also may include:

Palpitations. Palpitations (sensation of fast or ircontinual heart beat) are the many widespread complaint among patients with Mitral Valve Prolapse. The palpitations are commonly linked with premature ventricular contractions (the ventricles beat sooner than they should), however supraventricular rhythms (abnormal rhythms that start above the ventricles) have actually also been detected. In some instances, patients may endure palpitations without oboffered dysrhythmias (irconstant heart rhythm).

Chest pain. Chest pain associated via Mitral Valve Prolapse is different from chest pain linked via coronary artery condition and also is a constant complaint. Generally the chest pain is not choose classical angina, however can be reexisting and incapacitating.

Depfinishing on the severity of the leak into the left atrium in the time of systole (mitral regurgitation), the left atrium and/or left ventricle might come to be enlarged, resulting in symptoms of heart faientice. These symptoms incorporate weakness, fatigue, and also shortness of breath.

The symptoms of mitral valve prolapse might resemble various other medical problems or difficulties. Almeans consult your doctor for a diagnosis.

How is Mitral Valve Prolapse diagnosed?

People via Mitral Valve Prolapse often have actually no symptoms and also detection of a click or murmur may be discovered during a regime examination.

Mitral Valve Prolapse may be detected by listening with a stethoscope, revealing a "click" (produced by the extended flaps snapping versus each other in the time of contraction) and/or a murmur. The murmur is resulted in by some of the blood leaking back right into the left atrium. The click or murmur might be the only clinical sign.

In enhancement to a finish clinical history and also physical examicountry, diagnostic procedures for Mitral Valve Prolapse may encompass any type of, or a combination, of the following:

Electrocardiogram (ECG or EKG). A test that documents the electric task of the heart, shows abnormal rhythms (arrhythmias or dysrhythmias), and can sometimes detect heart muscle damages.

Echocardiogram (additionally referred to as echo). A noninvasive test that provides sound waves to evaluate the heart"s chambers and also valves. The echo sound waves produce an image on the monitor as an ultrasound transducer is passed over the heart. Echocardiography is the many beneficial diagnostic test for Mitral Valve Prolapse.

In some instances where symptoms are more major, additional diagnostic measures might be performed. Additional actions may include:

Stress test (also dubbed treadmill or exercise ECG). A test that is performed while a patient walks on a treadmill to monitor the heart during exercise. Breathing and blood pressure prices are likewise monitored.

Cardiac catheterization. With this procedure, X-rays are taken after a contrast agent is injected right into an artery to locate any kind of narrowing, occlusions, or various other abnormalities of specific arteries. In enhancement, the feature of the heart and the valves may be assessed.

Cardiac MRI. This is a noninvasive test that produces comprehensive imperiods of the heart. It might be provided as a match to echo for a much more precise look at the heart valves and heart muscle, or in preparation for heart valve surgery.

How is Mitral Valve Prolapse treated?

Specific treatment for mitral valve prolapse will certainly be identified by your doctor based on:

Your in its entirety health and medical history

Extent of the disease

Your indications and also symptoms

Your tolerance for specific drugs, steps, or therapies

Expectations for the course of the disease

Your opinion or preference

Treatment is not generally crucial as Mitral Valve Prolapse is hardly ever a serious problem. Regular checkups via a physician are advised.

People via rhythm disturbances might must be treated via beta blockers or other drugs to manage tachycardias (fast heart rhythms). In the majority of situations, limiting stimulants, such as caffeine and cigarettes, is all that is required to regulate symptoms.

If atrial fibrillation or significant left atrial enlargement is present, treatment via an anticoagulant might be recommfinished. This can be in the develop of aspirin or warfarin (Coumadin) therapy.

For the perboy with symptoms of dizziness or fainting, maintaining adequate hydration (liquid volume in the blood vessels) via liberal salt and liquid intake is important. Support stocmonarchs might be valuable.

If significant mitral regurgitation resulting from a floppy mitral leaflet, rupture of the chordae tendineae, or too much lengthening of the valve must happen, surgical repair may be suggested.
