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^® 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.
Use of Amplatz® canine duct occluder for closing a patent ductus arteriosus in a small-sized dog

A 2-year-old intact female pomeranian dog presented dys- pnea, labored breathing, cough, exercise intolerance, ma- chinery heart murmur, and precordial thrill. A left-to-right patent ductus arteriosus (PDA) was diagnosed based on two-dimensional echocardiography, thoracic radiography, electrocardiography, and blood work. An angiography was performed to accurately evaluate the size and shape of the duct. An interventional approach for transcatheterial oc- clusion of the PDA was achieved using an Amplatz ® Canine Duct Occluder (ACDO), which is a commercially available ductal occluding device. Due to the limited size of the dog’s femoral artery, a device smaller [125% of minimal ductal diameter (MDD); recommended size: 150~200% of MDD] than recommended was mounted. After placement of the ACDO, precordial thrill and continuous heart murmur dis- appeared, and the patient was discharged the next day after stabilization with O 2 supply. Upon follow up examination, dyspnea, labored breathing, cough, exercise intolerance, and cardiomegaly were improved with no complications after the procedure. The ACDO was well maintained in po- sition. This case represents successful clinical application of the Amplatz ® Canine Duct Occluder to achieve closure of a PDA using a slightly smaller device than the recommended size.
