Abstract

A 4 months old, intact male Shih-tzu was referred to the Veterinary Medical Teaching Hospital of Chungnam National University for evaluation of the cause of cardiac murmur and syncope. Thoracic radiography revealed right-sided cardiomegaly. Echocardiography showed marked hypertrophy of right ventricular free wall and obstruction of right ventricular outflow tract, indicating double chambered right ventricle (DCRV). The dog was medicated with atenolol and sildenafil for DCRV, however, clinical signs did not control by medication. Balloon dilation for DCRV was performed to ameliorate patient`s clinical signs. The peak systolic pressure gradient across the obstruction region was decreased and clinical signs was improved by balloon dilation procedure. This is the first case report of balloon dilation for the treatment of canine DCRV in South Korea.
