Preoperative Computational Fluid Dynamics Simulation of the Best Anastomosis Site and Angle of the Outflow Graft and Ascending Aorta in Continuous Flow Mechanical Assist Devices

Left ventricle assist devices (LVAD) have contributed to improve survival and quality of life in patients with advanced heart failure, in temporary or lifetime support. Despite technological, bio-compatibility and hemodynamic progress, patients with LVAD have still a relevant incidence of adverse events, such as disabling stroke. The outflow cannula (OC) position and angulation, and the anastomosis site seem to modify the flow in the ascending aorta (AA), and consequently the incidence of cerebral embolism and aortic cusps stress.
