Transvenous patent ductus arteriosus occlusion via Canine Duct Occluder in a cat
2021
Kharbush, R.J. | Trafny, D.J.
A 5-month old, intact, female domestic shorthair cat was referred for evaluation of a heart murmur. Echocardiography revealed a large, left-to-right shunting patent ductus arteriosus (PDA). One month after initial presentation, the cat underwent transvenous PDA occlusion via Amplatz occlusion device. A 4-mm Canine Duct Occluder (ACDO) was successfully placed via introduction into the right jugular vein and retrograde manipulation from the pulmonary artery across the ductal opening. No residual flow was detected postoperatively, and the patient recovered uneventfully without significant complications. At recheck evaluations one and seven months post-operatively, the patient was clinically well with trivial residual diastolic flow and improved left heart dimensions. This report demonstrates the feasibility of transvenous PDA occlusion via ACDO device in the feline patient, although further experience is needed to establish the repeatability and safety of this approach compared with alternative methods.
