Abstract : Background Mechanical and hemodynamic factors are among the determinants of patient-device interaction and early-term and long-term outcomes in left ventricular assist device LVAD recipients. Material and methods We are currently developing computer simulation tools aimed at 1 analyze the intrathoracic and intracavitary positioning of LVADs after implantation and establish correlation with clinical outcomes; 2 assist surgeons in the choice of device and of left ventricular coring site for optimized intrathoracic placement and function; and 3 facilitate the planning of less-invasive LVAD implantation. A virtual representation of LVAD mesh device component was created through cone-beam computed tomography and semiautomatic segmentation. A modular framework software CamiTK, Grenoble, France was used to create a three-dimensional representation of patients- computed tomography CT scan and incorporate the mesh device component for virtual implantation. Results Device reconstruction was included into a dedicated software with the purposes of virtual implantation, based on the preoperative CT scan of surgical candidates. Conclusions We present herein the first digital reconstruction of the novel HeartMate 3 LVAD. Virtual implantation on the basis of preoperative CT scan is feasible within a user-friendly interactive software. Future studies will be focused on correlation with clinical variables. © 2016 Elsevier Inc.
