Mobile Mitral and Aortic Valvular Masses in Patients With Hereditary Hemorrhagic Telangiectasia Receiving Intravenous Bevacizumab
Abstract
Bevacizumab is now an emerging treatment option for severe hereditary hemorrhagic telangiectasia–related bleeding including epistaxis and gastrointestinal tract bleeding. The impact of long-term intravenous bevacizumab therapy on cardiac structure and function is unknown. We describe 3 patients receiving intravenous bevacizumab therapy for severe hereditary hemorrhagic telangiectasia–related bleeding who were found to have abnormal mobile masses on the mitral valve (n=2) and aortic valve (n=1). The clinical impact of these findings is unknown and requires further study.
