Case Report: Concurrent atrial and ventricular septal defect in a young Sphynx cat.

ABSTRACT: Concurrent atrial septal defect (ASD) and ventricular septal defect (VSD) are rare in cats. A 7-month-old intact female Sphynx cat was presented for evaluation of respiratory distress and exercise intolerance. Thoracic radiographs showed generalized cardiomegaly and pulmonary infiltrates, consistent with cardiogenic pulmonary edema. Transthoracic echocardiography revealed an ostium secundum-type ASD and a perimembranous VSD, with structurally normal atrioventricular valves and annuli. These features supported the diagnosis of concurrent ASD and VSD, rather than an atrioventricular septal defect. Color Doppler echocardiography and agitated saline contrast studies confirmed bidirectional shunting at both defect sites. Additionally, echocardiographic findings were consistent with pulmonary hy
