RESUMO
A five-year-old intact male Golden Retriever was sent to our center for a second cardiac evaluation after the diagnosis of right atrial dilatation. Transthoracic and transesophageal echocardiographic evaluation and echo-contrast study were performed. A diagnosis of aneurysmal right auricle was issued without any sign of other cardiac pathologies. The tomographic evaluation was necessary to estimate the dimension of the aneurysmal area and exclude pericardial defects that may justify this anomaly. This report describes a rare case of aneurysmal giant right auricle in dogs. The diagnosis is accurate with the association of echocardiography and computed tomography.

Pulmonic stenosis is a frequent congenital heart disease in dogs, and the treatment of choice is balloon valvuloplasty which is usually safe and successful. The authors describe for the first time a severe complication after balloon valvuloplasty in a five-month-old dog. After effective treatment, with a considerable drop in right ventricular pressures, the dog developed hypoxemia and dyspnea due to pulmonary edema. The dog underwent intensive care and symptoms improved after a few hours of oxygen therapy, continuous positive airway pressure, and furosemide. Although this event is rare, it could have a large impact on patient survival and should be considered in the treatment of severe pulmonary valve stenosis in the future.
