Is Mitral Valve Prolapse Syndrome contagious?

Mitral Valve Prolapse Syndrome is not contagious and cannot be spread through touch, proximity, or any form of social contact. It is a structural condition of the heart valve, meaning it is physically impossible to transmit Mitral Valve Prolapse Syndrome from one person to another.

What causes Mitral Valve Prolapse Syndrome?

Mitral Valve Prolapse Syndrome is primarily caused by structural abnormalities in the mitral valve leaflets, which cause them to bulge or "prolapse" back into the left atrium during heart contraction. In most cases, this is a result of myxomatous degeneration, where the connective tissue of the valve weakens over time. It can also be associated with underlying connective tissue disorders, such as Marfan syndrome or Ehlers-Danlos syndrome, which are genetic rather than infectious.

Why is there confusion regarding contagion?

Confusion often arises because Mitral Valve Prolapse Syndrome is sometimes linked to a history of rheumatic fever, which is an infectious complication of a streptococcal throat infection. While the infection itself is contagious, the resulting heart damage—the valve prolapse—is not. Once the infection has cleared, the structural heart condition cannot be "caught" by family members or caregivers.

Is Mitral Valve Prolapse Syndrome hereditary?

While not every case is inherited, Mitral Valve Prolapse Syndrome does have a strong genetic component. Research indicates that it often runs in families, suggesting an autosomal dominant pattern in many affected individuals. If you have a family history, your physician may recommend the following:

• An echocardiogram to visualize the structure of your heart valves.


• Genetic counseling if the condition is suspected to be part of a broader connective tissue syndrome.


• Regular monitoring if you are asymptomatic but have a family history of the condition.

Addressing stigma and safety

Living with or being near someone with Mitral Valve Prolapse Syndrome poses zero risk to your health. There is no social stigma justified by this condition, as it is purely a physiological matter of heart anatomy. At DiseaseMaps.org, 23 people with Mitral Valve Prolapse Syndrome share their experiences, and we encourage you to connect with them to find support and accurate, non-judgmental information.

Next steps

• Consult a cardiologist for a definitive diagnosis via echocardiography.


• Join our community at DiseaseMaps.org to connect with others who understand the reality of living with Mitral Valve Prolapse Syndrome.


• Discuss your family medical history with your primary care provider to determine if screening is necessary for relatives.
