Key result
A prototype 3-D computer simulation system of the thoracic cavity and total artificial heart was constructed to evaluate anatomical compatibility and optimal morphology.
A 3-D thoracic modeling system based on CT imaging was developed to simulate and evaluate the anatomical compatibility of implantable total artificial hearts.
Enables preoperative fit assessment for total artificial hearts; extends computational tools but leaves open clinical translation.
Anatomical compatibility with the thoracic cavity is important in developing a completely implantable total artificial heart (TAH). The purpose of this study was to examine the optimal morphology of our TAH and to develop a computer implantation simulation environment for preoperational discussion. As the first stage, we constructed a prototype simulation system by creating a 3-D surface model of a thoracic cavity and one of a TAH. In this system, the thoracic surface model, composed of the aorta, pulmonary artery, ventricle resected heart, diaphragm, and thoracic wall, was created based on the organ contours extracted from electrocardiogram (ECG)-synchronized ultrafast computer tomographic images. The accuracy of the thoracic model was discussed using a phantom. The fitting study can be performed on the computer with the model of the thorax and that of the TAH. In the future, construction of a database for the thoracic cavities of heart failure patients is planned to improve the morphology of the TAH.
