text: In the lab, we checked the scene,
  Patients aged 79, 80, and 81, if you know what I mean.
  Autopsy revealed cardiac malformations, so unclear,
  Couldn't decide if they were congenital or acquired, my dear.
  
  First case, we spotted a fibromuscular subvalvular aortic stenosis,
  Like a band-shaped formation, causing some doses.
  Second case, an isolated aneurysm, hold on tight,
  Membranous septum directed to the right, out of sight.
  
  Combined with a tiny diverticulum, muscle part of the septum,
  Aneurysm faced the tricuspid valve, no need to assume.
  Two tunnel-like formations, projecting to the sky,
  Ending blindly beneath the atrial septal endocardium, oh my!
  
  Ventral canal sticking into the right atrium space,
  Dorsal one reaching the left, finding its place.
  Regressive changes, inflammation, things not right,
  Terminal parts of these channels, a real fight.
  
  Moving on to the third case, hold your applause,
  Aneurysms of the Valsalva sinuses, breaking laws.
  That's what we found, deep in the heart's core,
  Pathological lesions, knocking at the door.
