Abstract
Ponatinib is a third-generation tyrosine kinase inhibitor with potent efficacy in the treatment of acute and chronic leukemia. Despite having an effective and sustained activity in all BCR-ABL1 mutations, it may cause cardiovascular adverse effects. Here we report a 56-year-old male patient with Chronic myeloid leukemia and no prior cardiac disorder who developed acute heart failure under ponatinib treatment. Guideline-recommended medical treatment for heart failure was initiated. Coronary angiography to exclude ischemic heart disease revealed no coronary stenosis. Cardiac magnetic resonance imaging showed findings consistent with non-ischemic dilated cardiomyopathy. After interruption of ponatinib treatment, cardiac evaluation showed improvement in left ventricular ejection fraction. Patients on Ponatinib therapy should be closely monitored for signs and symptoms of heart failure.
