Peripheral pulmonary artery stenosis in a four-month-old West Highland White Terrier.
A 4-month-old West Highland White Terrier was evaluated for dyspnea. Severe cardiac silhouette enlargement was present radiographically. Severe right ventricular hypertrophy and dilation with a dilated pulmonary trunk and a stenosis of the right pulmonary artery were diagnosed via echocardiography. Additional areas of peripheral pulmonary artery stenosis were diagnosed with nonselective computed tomography (CT) angiography and selective fluoroscopic angiography. Balloon dilation therapy was unsuccessful and the imaging findings were confirmed at necropsy.
