Congenital tricuspid dysplasia in a Vietnamese pot bellied pig.
A 10-day-old 1.5 kg, female, Vietnamese pot-bellied pig (Sus scrofa) was presented because of respiratory distress and acute collapse that had occurred following mild exercise. Thoracic auscultation revealed a grade III/VI holosystolic murmur with the point of maximal intensity on the right hemithorax. Thoracic radiography, colour flow Doppler echocardiography and selective angiocardiography were used to diagnose congenital tricuspid valve dysplasia. Postmortem evaluation confirmed the echocardiographic and angiocardiographic findings.
