Mitral valve prolapse (MVP)

Mitral valve prolapse is a common condition where the flaps of the heart's mitral valve bulge or flop into the left atrium during contraction. While often harmless, it can sometimes cause minor symptoms or lead to blood leaking backward through the valve.

Overview

Mitral valve prolapse is a common condition where the flaps of the heart's mitral valve bulge or flop into the left atrium during contraction. While often harmless, it can sometimes cause minor symptoms or lead to blood leaking backward through the valve.

Understand this condition

The mitral valve acts as a one-way gate between two chambers of the heart. In MVP, the valve flaps are floppy and billow backward, sometimes allowing blood to leak the wrong way.

Why it happens

It usually happens because the valve tissue is too thick or stretchy, making it fit poorly. Over time, the valve can stretch further, though for most people, the condition remains stable.

Real-world scenarios

  • This often appears as a slight fluttering in the chest during stress.
  • People may notice they get winded more easily during light exercise.
  • A doctor may find it during a routine checkup for unrelated issues.
  • This often appears as a sudden, brief sharp pain in the chest.

Common vs serious explanations

Common
  • Normal heart rhythm variation during exercise or stress
  • Benign heart murmur heard during a routine physical exam
  • Anxiety-related racing heart or palpitations
  • Mild dehydration causing temporary heart rhythm changes
Serious
  • Severe mitral regurgitation causing blood to flow backward into the lungs
  • Endocarditis, which is an infection of the heart valve lining
  • Atrial fibrillation or other dangerous heart rhythm disturbances
  • Congestive heart failure due to long-term valve leakage

Primary symptoms

No symptoms mapped yet.

Causes

  • Genetic connective tissue disorders
  • Elongated or thin chordae tendineae (heart strings)
  • Degeneration of heart valve tissue

Risk factors

  • Family history of MVP
  • Marfan syndrome or Ehlers-Danlos syndrome
  • Scoliosis or chest wall deformities
  • Age (common in adults over 50)

How it progresses

3 stages
  1. Onset
    Symptoms appear, often triggered by a known cause.
    Often missed
  2. Active phase
    Symptoms peak; self-care or short treatment usually helps.
  3. Resolution
    Symptoms ease over days to weeks with proper care.

How it's diagnosed

  • Physical exam for heart murmur/click
  • Echocardiogram (ultrasound)
  • Electrocardiogram (ECG)
  • Exercise stress test

Treatment options

General educational information only — no dosage advice. Always follow guidance from a qualified clinician.

Medical
  • Regular monitoring with "watchful waiting"
  • Beta-blockers for palpitations
  • Blood thinners if arrhythmia is present
  • Valve repair or replacement surgery (rarely)
Home care
  • Regular aerobic exercise
  • Reducing caffeine and stimulants
  • Staying well-hydrated
  • Routine dental hygiene to prevent infection

Complications

  • Reduced quality of life
  • Worsening symptoms over time
  • Recurrence of mitral valve prolapse (mvp)

Prevention

  • Maintain a healthy lifestyle
  • See a clinician for routine check-ups

When to seek help

Urgent — same-day care
  • Symptoms persist beyond a few days
  • Symptoms interfere with daily activities
  • New or worsening symptoms appear
  • Concerning changes related to mitral valve prolapse (mvp)
🚨 Emergency — call now
  • Severe shortness of breath
  • Fainting or near-fainting episodes
  • Sudden, sharp chest pain
  • Rapidly worsening leg swelling

In any emergency, call your local emergency number or go to the nearest emergency department.
