About this study

The purpose of this study is to compare conventional assessment of systolic ventricular function on a 2D heart echo with an assessment of more immediate changes in heart mechanics using 2D and 3D measurements of deformation and strain in patients undergoing infusion of Trastuzumab for breast cancer.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
