infants with bicuspid heart valve

  Our son was born with a bicuspid heart valve.  The pediatrician called it a pulminary click, I think.  He said it is a somewhat common disorder and to check with a heart doctor once a year.  However, I have read elsewhere that some types of exercise may have to be restricted.  If so, is there a certain age that we should begin these restrictions, and what kind of specific restrictions should there be.  Also, if you could give me a source for more information on this I would appreciate it.  Thanks
