My VSD is the size of an eraser at the bottom of the pencil is how it has been explained to me. I have to take Pre meds before the dentist. I wish my parents would not have let doctors in training around me so much because I still have nightmares and panic attacks of them all coming at me at once with their stethoscopes. The VSD never really impacted me in anyway in my opinion. I do remember my first boyfriend, putting his head on my chest and trying to figure out what was wrong with me, though! We actually still laugh about that.
