Subsequently, she was treated with auto peripheral blood stem cell transplantation. Although a complete remission was obtained, heart failure developed two months later. Echocardiography showed an impaired systolic function with peri-cardial effusion. A biopsy of the endomyocardial region from the left ventricle demonstrated spotty myocar-dial hemorrhage and myocardial fibrosis with disruption and aggregation of mitochondrial cristae. Based on these findings, CY-induced cardiotoxicity was diagnosed. The patient was treated with conventional therapy for heart failure, which required approximately one year to improve her condition., Internal Medicine, 52(20), pp.2311-2315; 2013}, pages = {2311--2315}, title = {Cyclophosphamide-induced Cardiotoxicity with a Prolonged Clinical Course Diagnosed on an Endomyocardial Biopsy}, volume = {52}, year = {2013} }
