RIGHT VENTRICULAR DYSFUNCTION IN PATIENTS WITH BREAST CANCER EXPERIENCING CARDIOTOXICITY DURING TRASTUZUMAB THERAPY

Cardiotoxicity during cancer therapy is defined based on changes in left ventricular (LV) ejection fraction. Right ventricular (RV) dysfunction during cardiotoxicity and its prognostic implications have not been examined. We sought to determine the incidence RV dysfunction at time of LV defined
