Intervention Technique using Transvenous Patent Ductus Arteriosus (PDA) Occluder in a Dog

Abstract

The first case interventional technique of Patent Ductus Arterious (PDA) correction was conducted in a 2 years old Golden Retriever. The dog was presented with continuous murmur with a marked left-side heart enlargement, insufficiency of pulmonic, mitral, and aortic valves. The definitive diagnosis for PDA was performed by echocardiography. The dog received PDA correction with interventional PDA occluding device consisting of nitinol wire mesh under fluoroscope at the Small Animal Teaching Hospital, Faculty of Veterinary Science, Chulalongkorn University with collaboration by medical expertise from Faculty of Medicine, Chulalongkorn University. The procedure was successful as measured by complete occlusion of PDA and no major complication. At one month after correction, the dog was more healthy and energetic while echocardiography showed a reduction of left ventricular dimension and improved valvular insufficiency. At six months after correction, the dog had smaller heart size with improved cardiac function.
