Successful interventional occlusion of muscular ventricular septal defect in a dog

Can Vet J. 2024 Mar;65(3):221-226.ABSTRACTVentricular septal defect (VSD) is a rare congenital heart disease in dogs. Hemodynamically important interventricular defects must be closed to improve the prognosis. This case report describes successful interventional transcatheter closure of a muscular VSD in a young Maltese and poodle mixed-breed dog with a large muscular interventricular defect (~5 mm in diameter) with a high rate of left-to-right shunt flow. The VSD was closed with a customized Amplatzer-type VSD occluder via a percutaneous transvenous (jugular) approach. We concluded that interventional occlusion of a muscular VSD with an Amplatzer-type occluder is a viable treatment option for dogs. A regular follow-up study for this dog is ongoing and has not detected complications. Key clinical message: Interventional occlusion of a muscular VSD with an Amplatzer-type occluder is a viable treatment option for dogs.PMID:38434169 | PMC:PMC10880404
