Try this website. www.medicinenet.com/mitral_val...
It explains this condition surrounded by relatively plain English.
what about the British heart foundation? Or enjoy you tried wikipedia and looked up heart disease?
By far the best site is The American Heart Association! You can even get monthly emails give or take a few heart conditions.
