Key result
Transthoracic echocardiography significantly underestimated left atrial volume (28 ± 12 mL/m2) compared to 64-MDCT echocardiographic views (53 ± 15 mL/m2; p<0.001).
Why the study?
Does transthoracic echocardiography accurately measure left atrial volume compared to 64-MDCT 3D reconstructions?
Population
52 patients who underwent transthoracic echocardiography and MDCT within 3 days
Comparison
Transthoracic echocardiography (TTE) vs 64-MDCT 3D chamber reconstructions
Design
Cross-sectional, Two independent observers calculated estimates

Echocardiography may underestimate left atrial volume; cross-sectional data leave open MDCT's prognostic utility.

Transthoracic echocardiography significantly underestimates left atrial volume compared to 64-MDCT, suggesting MDCT can provide more accurate and potentially additive prognostic information.
Koka et al. (2010) conducted a cross-sectional in Patients undergoing cardiac imaging (n=52). Transthoracic echocardiography (TTE) vs. 64-MDCT was evaluated on Left atrial volume (p=< 0.001). Transthoracic echocardiography significantly underestimated left atrial volume (28 ± 12 mL/m2) compared to 64-MDCT echocardiographic views (53 ± 15 mL/m2; p<0.001).
