I went with my daugher-in-law last week to the Dr. she is 6 months pregnant they did an ultra sound and after spending a lot of time looking at the baby's heart the Dr. said,"What we have here is an enlarged Pulmonary artery." the US tech asked if she should make an appt with the Pediatric cardiologist and he said lets wait until we check her on her next visit…4 wks away…..I have tried everywhere to find out what we can expect and nothing…please help!
