[|Human|] My sister just turned 22. She is 5ft 2inches 105lbs. She had PDA heart surgery at 11months. She is highly allergic to milk n smoke. She avoids both. She looks very healthy n leads a very active life. She has never had any other health problems, loves to workout n takes no meds. But for the past few months she gets shaky, dizzy, breathless  n her heart races off n on. Could this be related to her heart?? Do others who have had PDA surgery as babies develop problems later?? I believed after her surgery as a baby they considered her cured. Thank you soo much for your time n help! :)
[|AI|]  Yes it can be related to her heart PDA cause left to right shunt IIN initial stages but if remain uncorrected for a long time this left to right shunt converts into right to left shunt due to severe enlargement hypertrophy of muscles of right ventricle. 2 d echo of your sister should be done asap its a possibility that duct became open , or operation was a partial success .all answers to your question lies in 2D echo report
