I Was Diagnosed With Mitral Valve Prolapse Many Years Ago.

I was diagnosed with mitral valve prolapse many years ago. Over the past couple of years, I have been bothered with PVC's. Last week, after a CTA scan, my doctor gave me the news that I have VSD. in my state of anxiety over this, I neglected to ask the questions that I should have asked. how serious is all of this together and are these conditions related? I think my doctor may think that stress is causing the VSD as I just lost my husband a few months ago.
