  1. Grade I: The whole cross-sectional "en face" view of the PV could be visualized on the reconstructed 3D image, Grade II: One third of the PV was missing on the reconstructed 3D cross-section image, Grade III: At least the half of the PV could not be displayed on the reconstructed 3D cross-section image
  2. 3D Three-dimensional, 3DTOE Three-dimensional transesophageal echocardiography, PV Pulmonary vein, LSPV Left superior PV, LIPV Left inferior PV, RSPV Right superior PV, RIPV Right inferior PV
