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
- •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
- 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

- Active phaseSymptoms peak; self-care or short treatment usually helps.
- ResolutionSymptoms ease over days to weeks with proper care.
How it's diagnosed
- •Physical exam for heart murmur/click
- •Echocardiogram (ultrasound)
- •Electrocardiogram (ECG)

- •Blood thinners if arrhythmia is present
- •Valve repair or replacement surgery (rarely)
- •Regular aerobic exercise
- •Reducing caffeine and stimulants
