Patent ductus arteriosus ligation and pulmonary artery banding in a kitten

Patent ductus arteriosus (PDA) and ventricular septal defect were diagnosed in a 2-month-old, 0.9-kg, male kitten. This combination of PDA and ventricular septal defect in a cat has not been previously described. Surgical ligation of the PDA, together with palliation of the ventricular septal defect by pulmonary artery banding with a silastic band, successfully improved the kitten's condition.
