My 13 year old daughter was born with ASV defect, it was repaired when she was 7 months old.  She has had a few times in her life, when she was running or exercising, when she has experienced chest pain.  But, after she walks it off she is fine and the pain goes away after a few minutes.  Tonight, she was playing soccer and started experiencing a sharp pain in her chest.  It has been an hour and the pain has minimized some but she is feeling the urge to cough.
