An 8 month-old male Maltese (weighing 2.0 kg) was referred with loud heart murmur at routine physical exam in local animal clinic. Electrocardiogram found left ventricular hypertrophy pattern (4.5 mV R-wave). Diagnostic imaging studies revealed the elongation of left ventricle (LV) with classic triple bumps on the main pulmonary artery, aorta and left atrium on the ventrodorsal view of radiograph. Echocardiography revealed patent ductus arteriosus (PDA) duct and continuous turbulent shunt flow (maximal velocity 4.83 m/s) between the aorta and pulmonary artery with left to right direction. The PDA in this dog was successfully closed through femoral vein (transvenous approach) using a 5 mm Amplatz$^{(R)}$ Canine Duct Occluder. To the best of author's knowledge, this is the first case of PDA occlusion treated with Amplatz Canine Duct Occluder through femoral vein.

10개월의 수컷 말티즈견 (1.6 kg)이 간헐적인 기침과 지속성 심잡음을 주증으로 내원 하였다. 환축은 경흉부심초음파 검사와 혈관 조영검사를 통하여 좌우단락의 동맥관개존증 (PDA)으로 진단되었다. 혈관조영 검사를 통하여 동맥관의 형태 및 크기에 대해 평가한 뒤, 대퇴동맥으로 $Amplatz^{(R)}$ Canine Duct Occluder (ACDO) 장치를 삽입하는 투시 유도하 동맥관 폐쇄술이 시도되었다. 동맥관의 폐쇄직후 지속성 심잡음이 사라졌으며, 시술 후 실시된 혈관조영검사를 통하여 잔류혈류가 관찰되지 않았다. 투시 유도하에서 ACDO 장착 및 성공적인 동맥관의 완전폐쇄가 확인되었다. 환자는 시술 1일 뒤 퇴원하였으며, 임상증상 관찰 및 심장검사가 정기적으로 이루어 졌다. 시술 후 합병증은 발생하지 않았다. 결론적으로 본 증례의 경우 대퇴동맥내로 ACDO를 적용한 성공적인 동맥관개존증 폐쇄술에 대한 국내 첫 증례보고이다.

A 5-year-old female Cocker spaniel dog (body weight 7.0 kg) was presented with primary complaints of exercise intolerance and loud precordial thrill which was noticed since she was a puppy. Physical examination revealed a grade V/VI continuous murmur over the maximal point of the left basal area, bounding femoral pulse, but no differential cyanosis. Tall R waves were detected in electrocardiogram, suggesting left ventricular enlargement. Diagnostic imaging studies showed enlarged left ventricle, bulged descending aorta (dAo), markedly dilated right pulmonary artery, and continuous shunt flow between the dAo and main pulmonary artery. Based on these findings, the dog was diagnosed as left to right shunted patent ductus arteriosus (PDA). The patent ductus arteriosus was treated by lodging a PDA duct occluder via the transvenous approach. Clinical signs were markedly improved after the ductal occlusion, the shunt flow was mildly persistent. The case presented is the first case of PDA occluded by the PDA duct occluder via the transvenous approach in a small breed of dog. Although the residual shunt flow was mildly persisted, the dog was clinically normal without detectable murmurs.
