  Figure 1 Procedural process of computed tomography merged imaging with the trachea as reference.After uploading the raw CT images to the HeartNavigator - Structural Heart Disease system, a segmented volume rendering image is created. The RAO and LAO view cine images are used to focus the patient and CT images for the procedure. If minor deviations are observed, fine adjustment can be considered perioperatively.CT = computed tomography; LAO = left anterior oblique; RAO = right anterior oblique.
