Cor Triatriatum Sinister and Persistent Left Cranial Vena Cava in a Kitten

Abstract

An approximately 8-week-old, 0.61 kg, male Bengal kitten was evaluated by the referring veterinarian for a 5-day history of sneezing, lethargy, anorexia, coughing, and dyspnea. Thoracic radiographs revealed cardiomegaly with left atrial enlargement, a patchy distribution of pulmonary edema, and loss of abdominal detail.
