TLDR A dog with a rare heart clot died despite treatment, highlighting the need for better clot treatments in dogs.
This case study reported the first instance of a free-floating thrombus in the left atrium of a 14-year-old mixed-breed dog, which had a history of generalized alopecia and suspected hyperadrenocorticism. The thrombus was likely due to advanced mitral valve disease and left atrial dilation, conditions that increase hypercoagulability. The study emphasized the role of noncardiac diseases like hyperadrenocorticism in thrombus formation and the complexity of managing cardiac thrombi in dogs with concurrent health issues. Despite treatment, the dog died suddenly 19 days later, highlighting the need for specific testing, immediate treatment of underlying diseases, and consideration of prophylactic medication to manage thrombosis risk.
