My grandson was born with tetralogy of fallot. His first surgery was when he was 2 months old. For the past year and a half he has had to have an mri every six months to check the growth of his right chamber, to see if it was time to replace his pulminary valve. The surgeons and doctors got back to us and said to see the doctor and make plans for surgery in the next 3 to 4 weeks. A week after we were told this his cardiologist office called and said no he dosen't need surgery and we would need an mri in another year. Is it just me or does something not soung right? Would you get another opinion from somewhere else? I don't know what to do. Please help!
