Validation of Two‐Dimensional Methods for Left Atrial Volume Measurement: A Comparison of Echocardiography with Cardiac Computed Tomography

Background Left atrial volume (LAVol) is an important predictor of cardiovascular outcomes. Different formulas are applied to calculate LAVol using two‐dimensional transthoracic echocardiography (2DTTE) with variable reference values. The objective of the study was to evaluate the accuracy of methods to calculate LAVol by 2DTTE or cardiac computed tomography (CT). Methods and Results Overall 177 consecutive patients who underwent both a 2DTTE...
