It makes communication with colleagues easier [1] and creates unique images that are helpful in a variety of clinical scenarios [2]. Measurements of dis- tances, areas and volumes based on real time (RT) 3D datasets have been proven to be more accurate compared to measurements based on two dimensional datasets [3–6]. Several studies showed the usefulness of RT 3D TEE for Abstract Newest 3D software allows measurements directly in the en-face-3D TEE mode. Aim of the study was to ascertain whether measurements performed in the en-face-3D TEE mode are comparable with conventional measurement methods based on 2D TEE and 3D using the multiple plane reconstruction mode with the Qlab ® soft- ware. En-face-3D TEE is used more frequently in daily clinical routine during cardiac operations. So far measure- ments could only be done based on 2D images or with the use of multi planar reconstruction mode with additional software. Measurement directly in the 3D image (en- face-3D TEE) would make measurements faster and eas- ier to use in clinical practice. After approval by the local ethic committee and written informed consent from the patients additionally to a comprehensive perioperative 2D TEE examination a real time (RT) 3D zoom- dataset was recorded. Routine measurements of the length of anterior and posterior mitral valve leafets as well as mitral valve and aortic valve areas were performed in en-face-3D TEE, multiplanar reconstruction mode using Qlab ® -software (Philips, Netherlands) and 2D TEE standard views. Twenty nine patients with a mean age of 67 years undergoing elec- tive cardiac surgery/interventions were enrolled in this study.
