Bilateral renal artery occlusion: an unusual presentation of atrial fibrillation and hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy predisposes patients to atrial fibrillation and the development of systemic embolization. We describe a rare case of bilateral renal artery thrombosis which presented as acute renal failure requiring dialysis. The patient was successfully treated with a selective, continuous infusion of urokinase which resulted in the return of adequate renal function.
