Crocodiles have two of these structures separated by a hole called the foramen of Panizza (puh-NEEZ-zuh), and fish have one in front of and one behind the lamellar lacunae (laa-KOO-nay). Women with Turner's syndrome often have coarctation (co-ark-TAY-shun) of this structure, whose wall can rupture in a usually fatal condition called dis- secting aneurysm. The descending section of this structure separates into thoracic (thoh-RAA-sihk) and abdominal segments while the sinuses of Valsalva lead to is first branches, the coronary arteries.
