Abstract
Background Increased left atrial volume and reduced atrial emptying are predictors of adverse cardiac events in adults. The atrium in single ventricle hearts contributes to ventricular filling to a greater degree than in normal hearts. Standardized methods of determining atrial function in single ventricles are lacking. We aimed to assess the feasibility and reproducibility of quantifying atrial volumes and function in hypoplastic left heart (HLH) prior to the Glenn operation.

Monoplane 4CH and biplane methods showed high correlations for aEDV and aESV as well as small mean differences compared to 3D-SAO (Table 1)
CMR atrial volume assessment is feasible in hypoplastic left heart (HLH) prior to Glenn operation
