On page 1092, right column, the second sentence of the EROA calculation section contains an error in the solid angle correction equation. The correct sentence is printed below:
We tested 2 correction factors for the increased ISVSA owing to obtuse leaflet angle, θ (Fig. 2A): 1) planar angle correction = (ISVSA)(θ/180) (wedge leaflet configuration); and 2) solid angle correction = (ISVSA)[1−cos(θ/2)] (conical leaflet configuration) (5).
We apologize for this error.
