Biplane disc method may aid asymmetric LV volumetry in models; leaves open validation for clinical CAD assessment.
Does two-dimensional echocardiography accurately estimate volume in asymmetric model hearts compared to direct measurement?
Biplane two-dimensional echocardiography using the disc method provides accurate volume determination in asymmetric model hearts, which has implications for left ventricular volume assessment in patients with coronary artery disease.
Erbel et al. (1982) studied this question.
