Mitral Valve Prolapse

What Is Mitral Valve Prolapse?

Mitral valve prolapse, often abbreviated MVP, occurs when one or both leaflets of the mitral valve billow backward into the left atrium during each heartbeat instead of closing evenly and flatly. The valve leaflets become slightly redundant or floppy, losing the tension needed to stay properly aligned when the left ventricle contracts.¹

MVP is one of the most common valve conditions in the general population, and the vast majority of people who have it live entirely normal lives without ever experiencing a related complication. In many cases, the condition is discovered incidentally, when a clinician hears a distinctive clicking sound, sometimes followed by a murmur, while listening to the heart during a routine exam.²

While prolapse itself is common and usually benign, it can sometimes allow blood to leak backward through the valve, a separate condition called mitral regurgitation. Not everyone with MVP develops regurgitation, and the degree of leakage, when present, varies considerably from person to person and can change over time.¹

Most patients with mitral valve prolapse remain asymptomatic with an excellent prognosis throughout their lives.

Symptoms

Most people with MVP experience no symptoms at all and are entirely unaware of the condition until it is discovered during an unrelated medical exam. When symptoms do occur, they tend to be subtle and easy to attribute to other causes, which sometimes delays recognition of the underlying valve issue.²

Reported symptoms include chest pain that does not follow the typical pattern seen with coronary artery disease, shortness of breath, fatigue, and swelling in the lower legs. Palpitations, a sensation of the heart skipping, fluttering, or racing, are also common and may reflect the arrhythmias sometimes associated with the condition.²

Less commonly, people with MVP experience lightheadedness or episodes of fainting, known respectively as presyncope and syncope. These symptoms warrant prompt medical evaluation, since they can occasionally signal a more significant underlying arrhythmia that requires closer monitoring or treatment.²

Causes

The most common underlying cause of MVP is a gradual, degenerative change in the valve tissue sometimes called myxomatous degeneration, in which the normal supportive collagen structure of the leaflets weakens over time, allowing them to stretch and billow.³

Connective tissue disorders raise the likelihood of developing MVP considerably. Conditions such as Marfan syndrome, Ehlers Danlos syndrome, and osteogenesis imperfecta all weaken connective tissue throughout the body, including the delicate structures that support the mitral valve leaflets.³

Genetics also play a meaningful role. MVP can run in families, following either an autosomal dominant or an X linked inheritance pattern in different family groups, and researchers have identified several chromosomal regions linked to familial cases, though no single gene has been definitively established as responsible in most patients.⁴

Risk Factors

A family history of MVP is among the strongest known risk factors, given the clear genetic component observed in many cases. People with a diagnosed connective tissue disorder also face substantially higher risk, since the structural weakness underlying these conditions directly affects the tissue that supports the valve.³

MVP tends to be diagnosed somewhat more frequently in women than in men, and it is often identified during young adulthood, though it can be diagnosed at any age. Body build has also been studied as a possible association, with some research noting a higher prevalence among people with a slender build or certain skeletal features.¹

Having a related heart condition, such as an atrial septal defect or certain forms of cardiomyopathy, can also increase the likelihood of prolapse being present, since these conditions may alter the geometry of the heart chambers surrounding the valve.²

Complications

The most common complication associated with MVP is progressive mitral regurgitation, which can, over years, lead to enlargement of the left atrium and ventricle and eventually contribute to heart failure if it becomes severe and goes unaddressed.²

A distinct arrhythmogenic form of MVP has been identified in a smaller subset of patients, characterized by frequent abnormal heartbeats originating in the ventricles. In rare instances, this pattern has been associated with dangerous ventricular arrhythmias and sudden cardiac death, which is why cardiologists pay close attention to specific imaging and electrocardiogram findings that may indicate higher risk.⁵

Infective endocarditis, an infection of the heart valve tissue, is another recognized though uncommon complication, particularly in patients who already have some degree of regurgitation. Good dental hygiene and prompt treatment of infections elsewhere in the body help reduce this risk in susceptible individuals.¹

Treatment

The majority of people with MVP need no specific treatment beyond periodic monitoring with echocardiography to track valve function and confirm that regurgitation, if present, is not worsening over time.²

For patients who experience bothersome palpitations or chest discomfort, beta blockers are commonly used to help control heart rate and reduce symptoms without addressing the valve itself. When regurgitation becomes moderate to severe, treatment shifts toward managing the leakage directly, following similar principles used for other forms of mitral regurgitation.⁶

In patients identified as having the arrhythmogenic form of MVP, additional interventions may be considered, including catheter ablation to target the source of abnormal heart rhythms or, in carefully selected high risk patients, an implantable cardioverter defibrillator for protection against life threatening arrhythmias. Surgical repair of the valve itself has also been shown to reduce arrhythmia burden in some patients with significant bileaflet prolapse.⁵

Prevention

Because MVP is largely driven by underlying connective tissue characteristics and genetic factors, there is no proven way to prevent the condition from developing in someone predisposed to it. Prevention efforts instead focus on early detection and monitoring to reduce the risk of complications once the condition is identified.¹

People with a known family history of MVP or a diagnosed connective tissue disorder benefit from periodic cardiac evaluation, even in the absence of symptoms, since early identification allows any progression in regurgitation severity or arrhythmia risk to be caught and managed before serious complications develop.³

For those already diagnosed, maintaining regular follow up appointments, promptly reporting new symptoms such as palpitations or fainting spells, and practicing good dental hygiene to reduce endocarditis risk all represent practical steps toward avoiding the less common but more serious complications of the condition.²

Why Visual Communication Matters for Mitral Valve Prolapse

Patients told they have a floppy or billowing valve often struggle to picture what that actually looks like inside a beating heart, or to understand why a condition that causes no symptoms in most people can, rarely, lead to serious arrhythmias in others. Clear visuals help translate an unfamiliar structural finding into something patients can understand and discuss confidently with their care team.¹

Cardiology practices, medical education platforms, and patient facing health organizations rely on accurate illustration and animation to explain how MVP differs from normal valve function and how it relates to conditions such as regurgitation and arrhythmia.

• Illustrating normal mitral valve closure compared with the billowing motion seen in prolapse

Frequently Asked Questions

Is mitral valve prolapse dangerous?

For the vast majority of people, MVP is a benign finding that causes no symptoms and requires no treatment. A small subset of patients face a higher risk of arrhythmia or progressive regurgitation, which is why periodic monitoring remains important even for those without symptoms.²

Can mitral valve prolapse be inherited?

Yes. MVP frequently runs in families, following autosomal dominant or X linked inheritance patterns in different family groups. Having a close relative with MVP raises the likelihood of developing the condition.⁴

What is the difference between mitral valve prolapse and mitral regurgitation?

Prolapse refers to the valve leaflets billowing backward during contraction, while regurgitation refers to blood actually leaking backward through the valve. Prolapse can lead to regurgitation, but many people with prolapse never develop significant leakage.¹

Do people with MVP need antibiotics before dental procedures?

Most people with MVP do not require preventive antibiotics before dental work. Current guidelines generally reserve this precaution for patients with more significant regurgitation or additional risk factors, and a physician can clarify individual recommendations.¹

What symptoms should prompt someone with MVP to see a doctor right away?

New or worsening palpitations, chest pain, lightheadedness, or fainting spells all warrant prompt evaluation, since these symptoms can occasionally indicate a more significant arrhythmia associated with the condition.²

Is surgery ever needed for mitral valve prolapse?

Surgery is not needed for prolapse alone in most cases. It becomes a consideration when prolapse leads to severe regurgitation or when a patient has the arrhythmogenic form of the condition with a significant burden of dangerous heart rhythms.⁵
