Atrial septal defect closure in a midget toy poodle

Abstract

Background: Atrial septal defect (ASD) is a rare congenital cardiac disease, and there have been no reports about treatment of ASD in midget breed dogs. Case Description: A 7-month-old female toy poodle weighing 1.4 kg presented with cardiac enlargement. Echocardiography revealed a secundum type ASD, right ventricular and atrial enlargement, and pulmonary hypertension. Blood flow through the ASD exhibited left-to-right shunting. The dog underwent ASD closure via a hybrid approach, in conjunction with catheter techniques and thoracotomy. Ten months after treatment, cardiac enlargement and pulmonary hypertension were improved. Conclusion: Even in midget dog breeds ASD can be corrected via a hybrid approach.
