My beautiful granddaughter is 7 and was just diagnosed with ASD. Last month she had a seizure (only had one ever). We were set up with MANY tests, one of which an EKG. This showed abnormal tracing. With a follow up by a cardiologist we found a murmer, ultrasound, 1.64cm hole in atrium, enlarged right Atr and Ven. I was told about both procedures, the least envasive being the least preferred. Looking for a Dr. that takes our insurance right now. Any insight?
