Catastrophic antiphospholipid syndrome presenting as dilated cardiomyopathy with bilateral branch retinal artery thrombosis.

Cardiac manifestation of antiphospholipid syndrome (APS) is mainly in the form of left-sided valvular insufficiency, intra-cardiac thrombi or coronary artery occlusion. Dilated cardiomyopathy is a rare but important cardiac manifestation of APS, and responds well to adequate anticoagulation and steroids. We describe a case in which APS presented with dilated cardiomyopathy and bilateral retinal artery thrombosis.
