Chylothorax associated with right-sided heart failure in five cats.
Chylothorax associated with right-sided congestive heart failure was diagnosed in 5 cats. One cat had restrictive pericardial disease, with mild pericardial effusion, and a heart-base chemodectoma. Two other cats had congestive cardiac disease (tetralogy of Fallot and tricuspid regurgitation in 1 cat, and endocardial cushion defect and tricuspid dysplasia in the other), and 2 cats had idiopathic cardiomyopathy. All cats had jugular venous distention, and echocardiographic evaluation helped define the nature of the cardiac disease in these cats. Subtotal pericardiectomy resulted in resolution of the chylothorax in the cat with the heart-base tumor, whereas medical management of the right-sided heart failure temporarily decreased pleural effusion in the cat with tetralogy of Fallot and in the 2 cats with cardiomyopathy.
