A 10 month-old female (intact) Maltese dog was presented due to continuous heart murmur. The dog was diagnosed with patent ductus arteriosus (PDA) based on two-dimensional echocardiography, computed tomography (CT) and angiography. Transarterial coil embolization was used for transcatheter occlusion of the PDA. A single coil was placed successfully and effectively occluded the blood flow through the ductus. Continuous heart murmur disappeared immediately the coil placement and no residual flow was detected. Complications and safety following the procedure were evaluated regularly based on clinical signs, cardiac examinations and serum troponin-I concentrations. This is the first clinical application of coil embolization for transcatheter closure of PDA in a dog in Korea.

A 10-month-old intact male Maltese dog (body weight, 1.6 kg) presented with intermittent cough and abnormal heart sounds. The dog was diagnosed with a left-to-right patent ductus arteriosus (PDA) on the basis of the results of transthoracic echocardiography, color flow Doppler examination, and angiography. Transcatheter occlusion of the PDA was performed using the $Amplatz^{(R)}$ Canine Duct Occluder (ACDO) via the femoral artery. The device was placed under fluoroscopic guidance and successfully occluded the PDA. The continuous heart murmur disappeared immediately after the correction and no residual flow was detected. The dog was discharged the following day and regularly examined for complications and safety. This is the first report demonstrating the clinical application of ACDO for the transcatheter closure of PDA via the femoral artery in a small-breed dog in Korea.

A 9-month-old, intact female Maltese dog and one-year-old, intact female beagle dog were presented with continuous heart murmur. These 2 dogs were diagnosed as patent ductus arteriosus (PDA) based on the two-dimensional echocardiography and angiography. Due to the large shunt size, commercially available ductal occlude device was used for transcatheter occlusion of PDA. After Amplatzer$^{(R)}$ vascular plug placement, cardiac murmur was abruptly disappeared in Maltese dog and mildly decreased in beagle dog. Complications and safety after the procedure were evaluated regularly in these 2 dogs. This is first clinical application of Amplatzer$^{(R)}$ vascular plug for transcatheter closure of PDA in two dogs in Korea.
