First report of pentalogy of Cantrell in a calf: a case report

This report describes the diagnostic evaluation in a one-week-old, female Simmental twin-calf with the anamnesis of umbilical hernia. Weakness, anaemia, tachycardia and a systolic left sided murmur were signifi- cant clinical findings. Based on echocardiography, the animal was diagnosed with pentalogy of Fallot, whereas necropsy revealed the presence of Cantrell's pentalogy with Taussig-Bing syndrome and situs inversus of the liver. Pentalogy of Cantrell is a rare condition described in humans but not yet reported in calves.
