Thank you very much for the reply..Since it is my 1st pregnancy, I am little scared...
VSD is a very common heart defect. One that is 2mm in size is small and a hole smaller than 3-4mm in size will all close on their own at some point early on in life. To my understanding, there is nothing that really needs to be done and it doesn't require surgery. Because it's small it also is likely to not have any symptoms or adverse effects because the heart doesn't have to work harder. I know it sounds scary, but it's highly likely that everything will work out perfectly fine. After your next scan speak to your doctor about any other concerns you might have, and be sure to ask the questions that you have asked here. They might be able to explain things in better detail.
