Plain-English summary
A 3-year-old female Pembroke Welsh Corgi was referred to the vet for a heart murmur and diagnosed with a condition called patent ductus arteriosus (PDA), which is a heart defect. She underwent surgery to close the PDA, but afterward, there were concerns about bleeding due to von Willebrand disease (vWD), a blood clotting disorder common in her breed. While the surgery initially seemed successful, the duct reopened two months later, although her heart function remained stable for six years after the operation. This case highlights the importance of testing for vWD in breeds prone to this condition before heart surgery.

Abstract
A 36-month-old female Pembroke Welsh Corgi with a cardiac murmur weighing 12.6 kg was referred to the Matsubara Animal Hospital cardiology service. Echocardiography revealed a patent ductus arteriosus. The dog underwent ductus arteriosus closure using an Amplatz Canine Duct Occluder. After the operation, we suspected coagulation and a platelet disorder because of the slightly increased haemorrhage during the operation, postoperative purpura around the surgical wound inside of the thigh, and dog breed, which is known to be commonly affected with von Willebrand disease (vWD). Subsequently, type 1 vWD was confirmed. Complete occlusion was achieved 1 month after the operation; however, 2 months after the operation, recanalization appeared. Recanalization progressed gradually; cardiac redilation was not detected 6 years after the operation. The late recanalization was most likely associated with vWD. In canine breeds pre-disposed to developing vWD, pre-operative testing may be indicated prior to patent ductus arteriosus occlusion, though the prevalence of vWD is rare.
