Her serum creatinine increased from 1.5 to 2.3 mg/dL during this time period. Her baseline renal insuffciency was believed to be caused by an 8-year history of hypertension; however, the etiology of the increasing creatinine was unknown. The patient’s renal history included microscopic hematuria and a right kidney stone 2 months prior to presentation. A previous urologic evaluation, which included cystoscopy, was unremarkable.</p> <p>The patient’s medical history was also significant for a St. Jude’s mitral valve replacement 8 years prior to presentation. A recent echocardiogram revealed a high-velocity, jetting paravalvular leak of the mitral valve replacement. She had exhibited anemia since her mitral valve replacement. Her hematologic evaluation for anemia revealed severe intravascular hemolysis.</p>Wednesday, 05 Nov 2008 19:31:09 GMT
