Abstract
An 8 month old female Maltese (body weight 3.6 kg) was referred with primary complaints of dyspnea and exercise intolerance. Diagnostic imaging studies revealed marked cardiomegaly and prominent main pulmonary trunk dilation on thoracic radiography, abnormally arisen aortic roots (toward right ventricle) with left-to right shunted perimembraneous ventricular septal defect located underneath of aortic root, aortic root was located to predominantly to the right ventricle and pulmonary regurgitation (peak velocity 4.7 m/s, pressure gradient ~88 mmHg) from pulmonary over-circulation and hypertension on echocardiography, indicating double outlet right ventricle (DORV). The dog was treated with furosemide (1 mg/kg, BID) for reducing volume overload at right ventricle, spironolatcone (1 mg/kg) and enalapril (0.5 mg/kg) for minimizing deleterious cardiac remodeling, and sildenafil (1 mg/kg) for lessening pulmonary over-circulation and hypertension. The clinical condition of this dog was improved after 1 week of medical treatment. The dog is currently survived and regularly monitored.
