Will congenital aneurysm repeat itself?

As a baby, I was dx'd w/ a heart murmur, along w/ a small 'calcified area' just above my heart.  At the age of 25, this calcified area was dicovered to be an aneurysm that had ballooned to 6.3 cm.  It was repaired using a Hemashield WDV.  I'm concerned that the condition may repeat itself, and have no family hx to fall back on since I am adopted.  I was also dx'd w/ Sturge Weber syndrome, but no physician has ever mentioned Marfan or any similiarly related conditions.
