“…Hudsmith et al [28], using the biplane area-length method, established values of volume similar to ours, 97 ± 27 mL for all subjects, 103 ± 30 mL for males and 89 ± 21 mL for females, with differences probably due to the need for geometric assumptions with that method. Sievers et al [29], published reference diameters for the 2, 4 and 3-chamber views slightly lower than ours, probably due to the fact that they used prospective triggering, which yields lower values, as reported by the same authors [30]. Anderson et al [31] published that a LA area < 24 cm 2 and a depth < 5.8 cm included the upper 95 th percentile of the normal range.…”

BackgroundLeft atrial (LA) size is related to cardiovascular morbidity and mortality. Cardiovascular magnetic resonance (CMR) provides high quality images of the left atrium with high temporal resolution steady state free precession (SSFP) cine sequences. We used SSFP cines to define normal ranges for LA volumes and dimensions relative to gender, age and body surface area (BSA), and examine the relative value of 2D atrial imaging techniques in patients.For definition of normal ranges of LA volume we studied 120 healthy subjects after careful exclusion of cardiovascular abnormality (60 men, 60 women; 20 subjects per age decile from 20 to 80 years). Data were generated from 3-dimensional modeling, including tracking of the atrioventricular ring motion and time-volume curves analysis. For definition of the best 2D images-derived predictors of LA enlargement, we studied 120 patients (60 men, 60 women; age range 20 to 80 years) with a clinical indication for CMR.ResultsIn the healthy subjects, age was associated with LA 4-chamber transverse and 3-chamber anteroposterior diameters, but not with LA volume. Gender was an independent predictor of most absolute LA dimensions and volume, but following normalization to BSA, some associations became non-significant. CMR normal ranges were modeled and are tabled for clinical use with normalization, where appropriate, for BSA and gender and display of parameter variation with age. The best 2D predictors of LA volume were the 2-chamber area and 3-chamber area (both r = 0.90, p < 0.001).ConclusionsThese CMR data show that LA dimensions and volume in healthy, individuals vary significantly by BSA, with lesser effects of age and gender.

Screening tools for late-onset cardiomyopathy secondary to cancer treatment are lacking. Our findings support the use of cMRI for the evaluation of the left atrial volume, as an early marker of diastolic dysfunction, and myocardial delayed enhancement, as a marker of myocardial fibrosis and scaring. Longer follow-up and larger studies are still needed to better define the role of cMRI in the evaluation of childhood cancer survivors.

“…At the end of this chapter a summary of normal values for atrial dimensions, areas, and volumes is given based on a recent study by Maceira et al (2010) of 120 healthy subjects covering six decades. For a more extensive overview including indexed age-and gender-specific values, we refer to specific literature (Jarvinen et al 1994a, b;Anderson et al 2005;Sievers et al 2005;Hudsmith et al 2005Hudsmith et al , 2007Tsao et al 2008). Besides a reservoir function, the atrium also has a conduit function, and has an active contractile function.…”

How Much are Atrial Volumes and Ejection Fractions Assessed by Cardiac Magnetic Resonance Imaging Influenced by the ECG Gating Method?

Abstract: The gating method has a significant impact on atrial volume and EF measurements. Atrial EF is underestimated by using the prospective triggering technique.
