Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of valvular heart diseases especially
aortic valve regurgitation is more likely in your case son's case.
This valve is situated in the starting of
aorta.
So in regurgitation, instead or going forward, blood go backward fromm aorta to the heart.
And this kind of valvular heart diseases are common at young age.
So better to
consult cardiologist and get done detailed 2d echo.
If aortic valve defect is there then valvular replacement is needed.
Once this defect is corrected, his
chest tightness William definitely improve.
So consult cardiologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
