Relationship of LAA with adjacent structures.

Note: LAA, left atrial appendage; D, distance; LSPV, left superior pulmonary vein; LCX, left circumflex artery; Dmin, the minimum distance. D(LAA orifice-LSPV orifice): The distance from LAA orifice to LSPV orifice; D(LAA-LSPV) min: The minimum distance from LAA to LSPV; D(LAA-mitral ring):The distance between LAA orifice and mitral ring; D(LAA-LCA):The minimum distance from LAA to left circumflex artery. * indicates a significant (P<0.05) difference between males and females.
