Giant right atrial diverticulum in a foal.
A 5-month-old male Thoroughbred foal with a history of chronic septic arthritis of the tibiotarsal joint and recent respiratory distress was euthanized and a postmortem examination performed. A giant diverticulum communicating with the lateral aspect of the right atrial cavity of the heart was observed. Histologically, the wall was comprised of myocardial tissue containing cavernous vascular spaces. There was gross and histologic evidence of right-sided heart failure. Congenital right atrial diverticula are rare anomalies in humans and have not previously been reported in foals.
