In the near future, it is likely that 3-dimensional (3D) surgical endoscopes will replace current 2D imaging systems given rapid spreading of stereoscopy in consumer market. this evaluation study, an emerging technology, autostereoscopic monitor, compared with visualization mainly used laparoscopic surgery: a binocular visor, technically equivalent from viewer’s point view to da Vinci 3D console, and standard monitor. A total 16 physicians no experience interfaces performed 5 different...
Nowadays advanced heart failure is mainly treated through transplantation. However, the low availability of donors makes research alternative therapies urgent. Continuous-flow left ventricular assist devices (LVADs) are going to assume a more significant role in assisting failing heart. A recent challenge clinical practice possibility use LVAD as long-term therapy rather than bridge For this reason, comfortable devices, able dynamically adapt physiological cardiac demand relation patient...
