Background:This report describes an 82-year-old female patient who developed secondary hemolysis following transcatheter edge-to-edge mitral valve repair (teer) for severe mitral regurgitation. Case presentation:On the day of the procedure, upon returning to the ward, the urinary catheter drainage bag showed tea-colored urine accompanied by oliguria. Subsequent evaluation revealed decreased hemoglobin, elevated lactate dehydrogenase, reduced haptoglobin, and acute renal failure, with the final diagnosis of device-related hemolysis. Following high-dose hydration and diuresis, the patient avoided hemodialysis, and renal function recovered. After discontinuation of antiplatelet therapy, hemolysis symptoms were controlled, and hemoglobin levels gradually improved. Conclusions:In selected patients, temporary discontinuation of antiplatelet therapy may ameliorate symptoms, but the attendant thrombotic risk necessitates intensified surveillance and individualized management.
