Book excerpt: Abstract: The anatomical measurements are usually required for aortic stenosis patient for surgical procedures. The literature study shows that accurate and consistent procedure is not available to obtain the measurements of the heart anatomy. Data obtained from the literature varies across many parameters such as the state of the patient, the measurement definition and the procedure of obtaining the actual measurement. Most of the data studied was measured and analyzed in 2D planes but in reality human heart is a 3D structure and is oriented in 3D space differently in different individuals. In this work a procedure is developed to obtain 3D model of the heart anatomy with a required accuracy. Using the 3D model created, the measurement analysis was carried out to obtain parameters such as the diameter of annulus, aorta, area at the required cross section, 3D angle of the cross section and the volume of left ventricular outflow track (LVOT) and other. The DICOM image files from the computed tomography (CT) scan were used as an input. The software such as 3D DOCTOR, NX-IMAGEWARE and NX-5 were used to create the 3D model and the measurement analysis. The analysis of all the data obtained indicates this procedure and anatomical measurements of the heart by the 3D approach is more reliable than the conventional 2D approach. The measurements also show better consistency for a given set of input data. With the growing importance of the minimally invasive surgery (MIS), the developed procedure and data can give reliable assumptions to get stent diameter, forces on the aorta. It can also be used for the development of the customized presurgery models for MIS.
