Caval syndrome is a severe complication of canine heartworm disease in which affected dogs present with various clinical signs that are often life-threatening. In cases of severe infection, adulticidal treatment has numerous complications as a result of a marked immune response against dead worms. Therefore, several surgical and non-surgical methods, including interventional extraction, have been applied in veterinary medicine. Despite the usefulness and efficiency of conventional retrieval devices, a few associated limitations must be addressed to reduce their risks and increase their applicability. Herein, we introduced a case of treating three dogs with caval syndrome by applying a newly developed heartworm basket device. The dogs were diagnosed with heartworm disease by heartworm antigen testing and direct smear. Imaging findings revealed remarkable remodeling of the right heart and pulmonary vessels and the presence of heartworms in the right heart. Additionally, heartworms were confirmed in the distal part of the abdominal aorta and femoral arteries in one dog, indicating aberrant systemic migration of the worms. Under general anesthesia, the heartworm basket device was introduced into the right heart via femoral venotomy and arteriotomy in one dog and jugular venotomy in the other two dogs. Although the number of cases in this study was small, the basket device was successful in gradual and cautious extraction of the heartworms in all three dogs. They exhibited good prognosis of clinical symptoms as indicated by imaging analyses.
