Objectives: To characterize angiographic morphology and minimum internal transverse diameter of left-to-right shunting patent ductus arteriosus (PDA) in a large series of dogs.

Background: PDA is the most common congenital cardiac malformation in the dog. Transarterial ductal occlusion is increasingly performed to close this defect. While accurate assessment of ductal morphology and luminal diameter is important to assure optimal occlusion using catheter-delivered devices, such information is currently limited.

Animals, materials and methods: In 246 dogs representing 31 breeds with left-to-right shunting PDA, right lateral selective aortic angiograms were recorded and reviewed.

Results: PDA morphology conformed to four general phenotypes (types I, IIA, IIB, and III) which varied according to degree of ductal tapering, and the presence, absence, or location of abrupt...
