RATIONALE: Anthracyclines cardiotoxicity characterized by dilated myocardiopathy has been well described in the literature. However, anthracyclines-induced valvular diseases have been seldom reported. PATIENT CONCERNS: In this study, we present the case of a 62-year-old Chinese female patient with breast cancer developing severe mitral regurgitation after anthracycline exposure. DIAGNOSES: The patient was diagnosed with mitral regurgitation with preserved left ventricular ejection fraction and normal cardiac chamber dimensions in the sixth month after the last course of anthracycline-containing chemotherapy. However, continued decrease in LVEF with normal left ventricular wall thickness, and serial increases in left atrial and ventricular dimensions were observed in the follow-up echocardiography. INTERVENTIONS: Treatments with oral itraconazole at a dose of 75 mg/day and local wound care with ciclopirox olamine ointment were administered. OUTCOMES: The patient responded well to the treatment with perindopril, metoprolol succinate, spirolactone, and furosemide, and symptoms associated with heart failure were dramatically relieved. LESSONS: The incipient mitral regurgitation may serve as an early sign of myocardial dysfunction that can facilitate a timely recognition of cardiotoxicity, which is crucial to a timely change of chemotherapy regimen and an appropriate initiation of antiremodeling therapy that could limit anthracycline cardiotoxicity and improve overall outcome.
Liu et al. (Fri,) conducted a case report in Mitral regurgitation after anthracycline-based chemotherapy (n=1). Heart failure medical therapy (perindopril, metoprolol, spirolactone, furosemide) was evaluated on Clinical response and echocardiographic changes. A 62-year-old female breast cancer patient developed severe mitral regurgitation after anthracycline exposure, with symptoms significantly relieved by heart failure medical therapy.
