Measurement of PV ostium parameters. 2a left: Measurement of major (a, green line) and minor axis (b, yellow line) PV diameters as well as planimetric measurement of OA (blue line) from the „en face” 2D plane of a CCT image in case of a circular PV ostium. 2b middle: Measurement of the same parameters on a CCT image in case of an elliptic ostium. 2c right: Measurement of the same parameters on a 3DTOE image. PV (Pulmonary vein), a (The major axis diameter of the PV ostium), b (The minor axis diameter of the PV ostium perpendicular to „a”), OA (Ostium area), 2D (Two-dimensional), CCT (Cardiac computed tomography), 3DTOE (Three-dimensional transesophageal echocardiography)
