n = 15. All Doppler measurements are single plane (apical 4-chamber) unless noted. Volumetric data are biplane measurements. Data included from 2 subjects with left ventricular ejection fraction ≥40%.

E/e′average = ratio of the early mitral inflow velocity and mean of the medial and lateral annular tissue Doppler velocities; I = indexed to body surface area; LAmax = maximal left atrial volume; LVEDV = left ventricular end-diastolic volume; LVEF = left ventricular ejection fraction; LVESV = left ventricular end-systolic volume; LVSV = left ventricular stroke volume; PVAR = pulmonary venous atrial reversal.
