Plain-English summary
An 8-year-old cat developed right-sided congestive heart failure and severe breathing problems due to a condition called patent ductus arteriosus (PDA), which caused abnormal blood flow. Before surgery, the cat was treated with oxygen and sildenafil, which helped lower the pressure in the lungs. The cat then underwent surgery to close the PDA, and during the procedure, the pressure in the heart remained stable. After the surgery, the cat made a full recovery and showed no further symptoms.

Abstract
Right-sided congestive heart failure (CHF) developed secondary to severe pulmonary hypertension (PH) in an 8-year-old cat with a left-to-right shunting patent ductus arteriosus (PDA). Vascular reactivity was tested prior to shunt ligation by treatment with oxygen and sildenafil. This treatment was associated with a significant decrease in pulmonary artery pressure as assessed by echocardiography. Subsequently surgical shunt ligation was planned. During thoracotomy, digital occlusion of the PDA was performed for 10 min with simultaneous catheter measurement of right ventricular pressure, which did not increase. Permanent shunt ligation resulted in a complete and sustained clinical recovery. A lung biopsy sample obtained during thoracotomy demonstrated histopathological arterial changes typical of PH. Cats can develop clinically severe PH and right-sided CHF secondary to a left-to-right PDA even at an advanced age. Assuming there is evidence of pulmonary reactivity, PDA occlusion might be tolerated and can potentially produce long-term clinical benefits.
