Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired bone marrow disorder characterized by hemolytic anemia, neutropenia, thrombocytopenia, hemoglobinuria, and venous thrombosis. Cardiopulmonary bypass-induced complement activation may be associated with exacerbation of hemolysis in patients with PNH undergoing cardiac operations. We describe a 77-year-old man with PNH and critical symptomatic aortic stenosis who underwent successful aortic valve bypass operation without cardiopulmonary bypass as an alternative to conventional aortic valve replacement.
