Mitral valve prolapse

Mitral valve prolapse is usually benign, but mitral regurgitation and complications can occur in some cases, so symptoms and echocardiographic findings are evaluated together.

Disease category
Mitral valve prolapse is a condition in which the leaflets of the mitral valve become overly flexible, failing to close tightly and bulging into the left atrium.
Core mechanism
Most cases have a congenital predisposition, and familial occurrence has been reported, but the exact cause has not been established. Rheumatic fever, connective tissue diseases, and Graves' disease may be related factors.
Main causes · related factors
If the valve does not close properly, mitral regurgitation may occur, in which blood flows backward from the left ventricle to the left atrium during heart contraction.
Representative patterns
It is typically asymptomatic, but palpitations, shortness of breath, cough, fatigue, dizziness, anxiety, migraine, or chest pain may occur.
Individual differences
The risk may increase with age, and the clinical presentation may differ in individuals with hypertension or specific connective tissue, skeletal, or muscular diseases.
Diagnosis
Most people live without health problems, but some may develop arrhythmia, endocarditis, or heart failure, and these complications are often associated with regurgitation.
Management
Clicks or heart murmurs may be heard during examination, and echocardiography is used as the key test to evaluate valve structure and regurgitation.
Treatment/Research Status
The presence of prolapse itself does not necessarily indicate severe disease or significant regurgitation; therefore, symptoms, the degree of regurgitation, and cardiac function must be interpreted together.
Read Evidence
If the patient is asymptomatic and regurgitation is mild, observation alone may suffice. Depending on symptoms and the degree of regurgitation, medication, regular follow-up, or valve procedures/surgery may be considered.
Key Precautions
Most cases do not require treatment; however, the need for treatment increases when there is significant regurgitation with symptoms or when cardiac burden increases.

At a Glance

Mitral valve prolapse is a condition in which the leaflets of the mitral valve become overly flexible, failing to close tightly and bulging into the left atrium.

It is typically asymptomatic, but palpitations, shortness of breath, cough, fatigue, dizziness, anxiety, migraine, or chest pain may occur.

How the disease works

Most cases have a congenital predisposition, and familial occurrence has been reported, but the exact cause has not been established. Rheumatic fever, connective tissue diseases, and Graves' disease may be related factors.

If the valve does not close properly, mitral regurgitation may occur, in which blood flows backward from the left ventricle to the left atrium during heart contraction.

Variations in presentation among individuals

The risk may increase with age, and the clinical presentation may differ in individuals with hypertension or specific connective tissue, skeletal, or muscular diseases.

The broad framework of diagnosis and management

Most people live without health problems, but some may develop arrhythmia, endocarditis, or heart failure, and these complications are often associated with regurgitation.

Clicks or heart murmurs may be heard during examination, and echocardiography is used as the key test to evaluate valve structure and regurgitation.

Current status of treatment

The presence of prolapse itself does not necessarily indicate severe disease or significant regurgitation; therefore, symptoms, the degree of regurgitation, and cardiac function must be interpreted together.

If the patient is asymptomatic and regurgitation is mild, observation alone may suffice. Depending on symptoms and the degree of regurgitation, medication, regular follow-up, or valve procedures/surgery may be considered.

Most cases do not require treatment; however, the need for treatment increases when there is significant regurgitation with symptoms or when cardiac burden increases.

How to read clinical trials

Regular follow-up is conducted to monitor changes in symptoms, regurgitation, and cardiac function. NCT04067635 on ClinicalTrials.gov is a registry record for an observational study addressing mitral valve repair; however, effectiveness or standard of care cannot be determined by registration alone.

Points to verify during clinical consultations

In clinical practice, it is important to confirm symptoms and onset time, presence of palpitations, previous echocardiography results, family history, history of connective tissue disease or rheumatic fever, medications taken, and follow-up plans.
