Palliative balloon angioplasty in a cat with right pulmonary arterial branch stenoses and concurrent absence of the left pulmonary artery.
Unilateral absence of the left or right pulmonary artery with concurrent contralateral pulmonary arterial branch stenoses is an exceptionally rare disorder. We describe this anomaly in a cat with severe exercise intolerance and respiratory distress. Transthoracic echocardiography and angiography demonstrated the absence of the left pulmonary artery with concurrent right pulmonary branch stenosis. Palliative balloon angioplasty of the right pulmonary artery substantially reduced right ventricular systolic pressure load and alleviated the patient's clinical signs.
