20% of the population will have heart murmurs/Mitral valve prolapse and do not even know about it, unless it starts to cause symptoms
breath, chest pains, irregular heart
People with known heart
murmurs should get echo's of their hearts done, at least every 3 years (if they are asymptomatic) and annually if they have symptoms.
Only a small percentage of heart murmurs ever need medical interventions and it normally improves with the ageing process.
