I have recently had a Well Woman check-up and it was discovered that I have a floppy mitral heart valve. I have been told that this won't cause me any problems, apart from occasional palpitations. I also have to have antibiotics before I go to the dentist. Is this something that I was born with, or is it a sign of ageing? I am 42 and perfectly healthy otherwise.
