Table 2: Range of observed LAA volume data.

Shown categories are the maximum volumes of each patient, the minimum volumes, and the left atrial appendage ejection fraction (LAAEF). LAA volumes are expressed as the mean ± standard deviation (SD) over all 9 observations (3 observers and 3 repeated analyses) and average LAAEF percentage (%).
