Laniesse D, Hebert J, Larrat S, Helie P, Pouleur-Larrat B, Belanger MC. Abstract in English, French Tetralogy of Fallot associated with bidirectional shunting across a large ventricular septal defect, was found in a 6-year-old ferret. The prognosis associated with tetralogy of Fallot is usually poor. This case is interesting given the advanced age of the ferret. The bidirectional shunting, responsible for an acyanotic disease, may explain the unexpected prolonged survival in this ferret. PMID: 24790231 [PubMed - as supplied by publisher] [Posted in FML 8100]
