Reference absolute and indexed values for left and right ventricular volume, function and mass from cardiac computed tomography

Introduction Left ventricular (LV) and right ventricular (RV) volumetric and functional parameters are important biomarkers for morbidity and mortality in patients with heart failure. Purpose To retrospectively determine reference mean values of LV and RV volume, function and mass normalised by age, gender and body surface area (BSA) from retrospectively electrocardiographically gated 64‐slice cardiac computed tomography (CCT) by using automated analysis software in healthy adults. Materials and Methods The study was approved by the institutional review board with a waiver of informed consent. Seventy‐four healthy subjects (49% female, mean age 49.6 ± 11) free of hypertension and hypercholesterolaemia with a normal CCT formed the study population. Analyses of LV and RV volume (end‐diastolic, end‐systolic and stroke volumes), function (ejection fraction), LV mass and inter‐rater reproducibility were performed with commercially available analysis software capable of automated contour detection. General linear model analysis was performed to assess statistical significance by age group after adjustment for gender and BSA. Bland–Altman analysis assessed the inter‐rater agreement. Results The reference range for LV and RV volume, function, and LV mass was normalised to age, gender and BSA. Statistically significant differences were noted between genders in both LV mass and RV volume (P‐value
