I've been told that if it is severe enough it can cause symptoms,
But if it's only Mild, I don't think it would.
I have SLIGHT MR, and I get ectopic heartbeats.
So, I assume every person is different, and that every body is different and responds differently to MR or MVP or BOTH.
I've read that when MR is Severe is when it can possibly cause Heart Failure.
Do you have a cardiologist you see?
I would see if maybe you could an appointment as soon as possible, if for anything, just to put your mind at ease.
I have stomach problems and they cause my chest pain ( when I have it ), slight breathlessness sometimes and it aggrivates my ectopics.
