NASHVILLE, Tenn. (AP) — A post-mortem report says a pulmonary aneurysm killed the horse that won the Iroquois Steeplechase.
The preliminary necropsy obtained by The Tennessean (http://tnne.ws/K1Ytze) concluded that the horse Arcadius was killed after the pulmonary artery just above the heart ruptured a few minutes after the Nashville race ended Saturday.
The report said the rupture caused a massive hemorrhage and heart attack.
Pathologist Dr. Bruce McLaughlin of the state's Kord Animal Health Laboratory conducted the necropsy. He said in a statement that the 8-year-old gelding was otherwise in excellent health.
