The Jarvik 2000, with a postauricular cable, is a left ventricular assistance device with a driveline that is passed to the postauricular region subcutaneously. A titanium pedestal base that holds a 3-pin connector is fixed to the parietal bone, posterior to the auricle. Essentially, the device is fixed in the same position as a cochlear implant; however, the disadvantages include continuous mechanical stress on the cable by neck rotations, and the visibility of the apparatus. To improve such concerns, we adjusted the location of the pedestal of the lower parietal bone to just above the transverse sinus and closer to the mastoid process. To reach this point, the internal cable was passed through the retromastoid pathway commonly used in ventriculoperitoneal shunting. The thickness of the skull at this location is sufficient for safe fixation; however, preoperative evaluation by a neurosurgeon using CT is necessary.

Background: The rising heart failure rates globally show the pressing demand for treatment progress, especially in Left Ventricular Assist Devices (LVADs). Axial-flow pump LVADs are gaining notice for their small size, few moving parts, and potential for miniaturization, providing a vital option for heart transplants during donor shortages.
Objectives: Despite several studies on LVADs, there is a notable lack of research specifically comparing axial-flow pumps with similar technology.
Driveline infection in patients with implantable left ventricular assist devices (LVAD) remains common and crucial. Once a driveline exit-site infection reaches the LVAD component, radical treatment such as LVAD exchange may become necessary, although the clinical results are unsatisfactory. The Jarvik 2000 device, which utilizes a postauricular cable, allows the driveline to exit the body behind the ear (postauricular) instead of through an abdominal site.

Objectives: This study aimed to report the clinical outcomes of continuous flow left ventricular assist device implantation in end-stage chronic heart failure patients with a history of surgical left ventricular restoration.
Methods: We retrospectively identified 190 patients undergoing continuous flow left ventricular assist device implantation at our center from November 2007 to April 2020. In total, six patients underwent continuous flow left ventricular assist device implantation after various types of surgical left ventricular restoration procedures, including endoventricular circular patch plasty (n = 3), posterior restoration procedure (n = 2), and septal anterior ventricular exclusion (n = 1).

Implantation of continuous-flow left ventricular assist device in a narrow lumen is technically challenging to secure an optimal support. We experienced a patient with the transposition of the great arteries after the Senning procedure who was initially implanted with Jarvik 2000®. She presented with worsening heart failure symptoms 2 years after implanting Jarvik 2000®.
