Abstract: A 4-month-old, British Shorthair kitten was referred to our institute for evaluation of a heart murmur. Thoracic radiography and echocardiography revealed narrowing of the right pulmonary artery, accompanied by right atrial dilation and right ventricular hypertrophy. The systolic flow velocity across the stenotic lesion was 6.15 m/sec, with a pressure gradient of 151.42 mmHg. Computed tomography confirmed right pulmonary coarctation with concurrent interruption of the left pulmonary artery. Balloon angioplasty was performed, reducing the systolic flow velocity from 6.15 m/sec to 2.79 m/sec and relieving right ventricular pressure overload. One year later, thoracic radiography revealed left lung collapse and right lung hyperinflation; however, the patient remained asymptomatic. At 33 months post-diagnosis, the patient continued to thrive without any clinical signs.
