Hypertrophic cardiomyopathy (HCM) is the most often seen type of cardiomyopathy in cats. The cause is unknown but a genetic basis is thought to underlie some cases. Thromboembolism (TE) is a troubling complication in cats with myocardial disease. Two cats referred to Seoul National University Hospital for Animals with the paralysis of bilateral hindlimbs after vomiting. The cats were depressed and the bilateral hindlimbs were cyanotic, cool and painful. Heart murmur sounds were auscultated in both cases. Through radiographic and echocardiographic evaluation, HCM was diagnosed. TE at the distal aortic trifurcation was also visualized on abdominal ultrasonography. Both cats were expired and HCM and saddle thrombus were confirmed by postmortem examination in one cat.
