From: Morphofunctional cardiac changes in singleton and twin pregnancies: a longitudinal cohort study
Cardiac morphofunctional changes in women with singleton and twin pregnancies. †, p < 0.05 between two groups. A, late diastolic mitral flow velocity; BSA, body surface area; E, early diastolic mitral flow velocity; e’, average of early diastolic septal and lateral mitral annular velocities; IVC, inferior vena cava; LA, left atrium; LV, left ventricle; s’, average of systolic septal and lateral mitral annular velocities. Table 3 lists the detailed data on these and other variables
