@ramyapriya Hello, and welcome to Connect. Is this the first time that you have a report about your heart? Your report says the back flow is trivial from the mitral valve. Only a qualified medical expert can tell you if your condition is serious or not, and your doctor said not to worry. I am the daughter of a heart patient and I remember seeing the ultrasound on my dad's heart as they did it and saw his valve not closing very well. As we age, imperfections happen, and that's OK. It is best to accept this and not be stressed because the stress from worry can affect the heart. Heart disease isn't all doom and gloom, but it must be manged by a physician.

The mitral valve is actually kind of interesting. It reminds me of a parachute held by strings...the "heart strings". If you imagine that the parachute has a slit that opens and closes dividing it in half, that is what it is like. When there is a little bit of prolapse, the valve is bending instead of keeping the straight flap shape.

I know that my mitral valve has a slight bit of calcification and a little bit of back flow. I don't even think about it and the doctors were not concerned at all.
