I was diagnosed with mvp and have some leakage based on my echocardiogram . what's normal and abnormal ? thank you

Go With The Flow: Normal is no regurgitation (back flow) in the heart. In the 5-10% of people who have MVP, maybe up to 20% back flow (regurgitation) is OK.Beyond that, it depends on your overall health and what symptoms you have. Severe would be more than about 60% back flow (that is, blood not flowing in the correct direction, thus putting more strain on the heart to pump blood).Your dentist should know about it.
