Methods We performed a systematic review of the literature from 2003-2015 to identify all published studies that measured right and left ventricular parameters by CMR in healthy adult controls. The parameters of interest were: end-diastolic volume, end-systolic volume, stroke volume, ejection fraction, and mass (indexed to body surface area). Inclusion criteria were: SSFP-based acquisition and quantification on a short-axis stack using the method of discs. Exclusion criteria were: enrollment of non-healthy subjects, trained athletes, or overlapping data with other publications. Queries related to overlapping data were resolved by contacting the authors of the studies. We extracted ageand sex-specific data when available and stratified according to whether the papillary muscles were traced or not. We also accounted for the distribution of each parameter (rather than assuming a normal distribution), which was determined from a subset of individual patient-level data. Two observers reviewed the studies in duplicate and a third observer audited discordances. We performed a random-effects meta-analysis of the data (using the same approach developed for the American Society of Echocardiography chamber quantification guidelines) to generate pooled mean values for each parameter, upper reference values, lower reference values, and 95% confidence intervals surrounding each of these values.
