Implantation of Continuous-Flow Ventricular Assist Devices: Technical Considerations

摘要

The increased applicability and excellent results with left ventricular assist devices (LVADs) have revolutionized the treatment options available for patients with end-stage heart failure. Until recently, pulsatile devices have supported most patients who have undergone LVAD implantation. Although tremendous success has been achieved with these devices, their use is associated with significant comorbidity. This may be related to several factors including the need for extensive surgical dissection, a large pump, and a large-diameter percutaneous lead.
