Measuring the LV end-diastolic and systolic volume and calculating the EF can quantitate the status of LV systolic pump function. However, EF may underestimate LV performance in the presence of the increased afterload associated with severe aortic stenosis. Since bolus administration of contrast may provoke hemodynamic compromise and assessment of LV function can usually be obtained via echocardiography, contrast ventriculography is rarely indicated.
