About

This echocardiography study will characterize heart structure and function during labor. Imaging of the heart during the stress of labor could increase detection of subclinical cardiovascular disease using advanced imaging techniques. Cardiac serum biomarkers and complication rates will also be measured and compared between patients with and without evidence of cardiovascular disease on echocardiography.
