text: Yo, check it out, I got some knowledge to drop,
  About migraines and the things that make 'em pop.
  There's a connection, you see, between migraine and aura,
  And a little thing called PFO, I'm here to inform ya.
  
  Migraine gets better when a PFO is sealed,
  In patients with a big shunt, it's a real big deal.
  Inherited migraines and atrial shunts, they go hand in hand,
  In some families, it's a genetic command.
  
  The data shows that PFOs can cause aura to appear,
  In some patients, it's the reason for their migraine fear.
  But these findings also shed light on the bigger scheme,
  Understanding migraine's origins, even without a shunt, it seems.
