Transcatheter Occlusion of Patent Ductus Arteriosus using an Amplatz Canine Duct Occluder in a Dog

Abstract

A 1-year-old male Papillon dog was presented with Levine IV/VI continuous murmur diagnosed as patent ductus areteriosus by Doppler echocardiography, with 4.84 m/s shunting velocity flow. The sheath was inserted in the femoral artery, the contrast media was injected via pigtail catheter. The minimal ductal diameter of pulmonary side was about 2.1 mm. The 3.0 mm size of an Amplatz Canine Duct Occluder was received. Residual shunting were assessed by angiography immediately, 15 min after and by Doppler echocardiography 1 day and 7 days after the intervention. The residual shunting was seen little in immediately, but never seen in 15 min, 1 day and 7 days after intervention.
