My son was born with TOF and part of that is PVS. He had OHS in June and is doing AMAZING! I know of many kids that were born with PVS and did not need surgery, it resolved itself or got to a point where it would not need surgery. T&Ps for you all
I was going to suggest researching some of the information about TOF, as PVS is a part of that defect. My DS had the other three defects, but not PVS, so I can't comment on it specifically, but I've also heard it's not always surgical, but hopefully the cardiologist will be able to put your mind at ease. T&Ps for you.
