Abstract
Tyrosine kinase inhibitors with potent properties against vascular endothelial growth factor (VEGF) signaling pathway (VSP inhibitors) are effective antitumor agents in metastatic renal-cell carcinoma and are now increasingly used in the treatment of other tumors.1 Although VSP inhibitors have been associated with cardiomyopathy, the nature of this side effect is unclear. We report two cases of severe symptomatic, yet reversible, cardiomyopathy after VSP inhibitor therapy.
