If you still have any prayers available, you might divert some to my nephew. My sister posted this, which pretty much says it all:
"Back from cardiologist with Christian. Next step is 2nd opinion with ped cardiac surgion at Riley for possible surgery. PDA is bigger (hole from aorta to pulmonary artery) that should have closed at birth. Small chance of no surgery. But if no surgery, always chance of bacterial endocarditis (infection around sack of heart). Appreciate any prayers."
