“…29 Axial acquisition had the advantage of allowing for additional phasic volumetry of the atria for further studies and has also recently be reported to be more reproducible than short-axis slices for ventricular volumetry in patients with corrected tetralogy of Fallot. 30 Intraobserver and interobserver variability demonstrated results comparable to other studies with good agreement for end-diastolic volumes and less agreement for end-systolic volumes and …”

Background-Cardiac MRI is important in the treatment of children with congenital heart disease, but sufficient normative data are lacking. For ventricular volumes and mass, we sought to deliver reference centiles and to investigate sex effects. Methods and Results-We included 114 healthy children and adolescents, uniformly distributed spanning an age range of 4 to 20 years, as required by the Lambda-Mu-Sigma method to achieve a percentile distribution, thus avoiding arbitrary age categories. Subjects underwent axial volumetry (1.5-T scanner) using standardized 2D steady-state free-precession and flow protocols. Percentiles were computed for age 8 to 20 years (99 subjects) because breath-holds were more consistent in this group. When indexed for body surface area or height, the centile curves of ventricular volumetric parameters showed allometric increase until adolescence, when a plateau was reached, with values comparable to published adult reference data. In contrast, ventricular mass centiles increased without plateau. There was a significant sex difference, with centiles reflecting larger values in boys than in girls (PϽ0.05) when ventricular volumes were indexed to body surface area or height but not when indexed to weight (exception: mass). There was excellent agreement of axial and short-axis volumetry and of volumetric and flow-derived stroke volumes. Conclusions-Percentiles for ventricular volumes and mass in healthy children have been established to serve as reference values in pediatric heart disease. Significant sex differences were noted when indexing volumes to body surface area or height. Unisex centiles related to weight may be considered for chamber volumes albeit not for mass.

“…Il est intéressant de noter que les mesures de volumes VD réalisées sur des piles de coupe axiales conduisent à une variabilité inter-et intra-observateurs signifi cativement meilleure que si l'on utilise des coupes petit axe, chez des sujets témoins [2] tout comme chez les patients avec tétralogie de Fallot opérée [8].…”

Les diffi cultés d'analyse du ventricule droit (VD) par échocardiographie sont bien connues. Dans ce domaine, l'avantage de l'imagerie en coupe réside dans l'absence de toute modélisation géométrique pour quantifi er les volumes et la fonction systolique du VD. En outre, l'IRM off re une quantifi cation des fl ux très utile pour estimer les fuites pulmonaires ou tricuspides et pour quantifi er le rapport des débits Qp/Qs. Les applications cliniques essentielles concernent : l'HTAP, l'infarctus du VD, la dysplasie du VD et surtout les cardiopathies congénitales de l'adulte altérant le VD. Le scanner cardiaque off re une résolu-tion spatiale supérieure à l'IRM, mais sa place pratique reste limitée dans les pathologies du VD car l'approche fonctionnelle est inférieure à celle de l'IRM et en raison de la nécessité d'injection d'un produit de contraste iodé ainsi que de son caractère irradiant.
