Plain-English summary
A group of 19 cats in the UK were diagnosed with a heart condition called patent ductus arteriosus (PDA), which can cause abnormal blood flow. Most of these cats were referred for a heart murmur that was found during a routine check-up, and some showed signs of illness like difficulty breathing. Treatment outcomes varied, with some cats developing additional heart problems, which affected their survival time. On average, cats diagnosed with PDA lived about 898 days after their diagnosis, but those with other congenital issues had shorter lifespans.

Abstract
Patent ductus arteriosus (PDA) is infrequently reported in cats and represents between 1-7.3 per cent of left to right shunting cardiac congenital anomalies. The objective of this study was to report the presenting complaints, clinical examination findings, diagnostic findings, treatment outcomes and survival times in cats diagnosed with a PDA in the UK. Medical records from three major UK referral centres were searched for cats that were diagnosed with PDA from January 2004 to December 2012. Data obtained for analysis included: signalment, clinical examination findings including murmur characteristics, diagnostic imaging findings, treatment outcomes and survival times. Nineteen cats were included in the analysis. The most common reason for referral was investigation of an incidentally detected heart murmur without clinical signs (13/19; 68 per cent). Pulmonary arterial hypertension (PAH) was diagnosed in seven (37 per cent) cats and those cats with PAH were significantly more likely to present with signs of disease (P=0.004). Median survival time in cats that were diagnosed with PDA and died due to cardiac causes was 898 days (interquartile range 459-1011 days). The median survival time of those cats that had an additional congenital anomaly was significantly shorter to those cats without a congenital anomaly (P=0.008).
