Pulmonary artery banding in a kitten with a partial atrioventricular septal defect

A 9-month-old kitten with increased resting respiratory rate and exercise intolerance was diagnosed with a congenital partial atrioventricular septal defect causing pulmonary over circulation and presumed pulmonary hypertension based on echocardiogram. Invasive pressure measurements and contrast angiography confirmed this diagnosis. The cat underwent pulmonary artery banding under general anesthesia. Findings of echocardiogram 10 days postoperatively suggested reduced left-to-right shunt volume. Echocardiographic findings were static 4 months postoperatively. (C) 2019 Elsevier B.V.
