Snippet: Disclosures: No disclosures to report. Patent ductus arteriosus (PDA) is one of the most common congenital cardiac diseases in dogs. ECG-gated computed tomography angiography (CTA) can be a complementary minimally-invasive way in early planning of interventional occlusion. The aim of this prospective observational study was to report CTA findings associated with PDA. A total of 25 dogs diagnosed with PDA aged 2 to 54 months and weighing 2.5 to 38.....
Document: Disclosures: No disclosures to report. Patent ductus arteriosus (PDA) is one of the most common congenital cardiac diseases in dogs. ECG-gated computed tomography angiography (CTA) can be a complementary minimally-invasive way in early planning of interventional occlusion. The aim of this prospective observational study was to report CTA findings associated with PDA. A total of 25 dogs diagnosed with PDA aged 2 to 54 months and weighing 2.5 to 38.1 kg were enrolled: all dogs were planned to undergo possible interventional occlusion under the same anesthetic directly after CTA. The contrast medium injection protocol was individually tailored with total injection time equaling the sum of diagnostic scan delay and scan duration. First, 1 ml/kg undiluted contrast medium (370 mgI/mL) was administered for two thirds of the total injection time, directly followed by 2 ml/kg of 1:1 diluted contrast medium for one third of the total injection time. The CT scan was triggered manually under a single breath hold when the contrast bolus reached the descending aorta. Scanning was commenced regardless of the heart rate.
