Surgical Implantation

Implantable left ventricular assist devices (durable LVADs) have dramatically improved mortality and morbidity in patients with advanced heart failure. Originally designed as a bridge or candidacy to heart transplantation, the indications extend toward permanent support and palliation. Modern durable continuous flow LVADs are small, commercially available, and allow for different surgical approaches to a wide range of patients with various cardiac pathologies. We will review different surgical implantation techniques of modern continuous flow LVADs, as well as specific aspects of preoperative patient evaluation and planning.

Single Part

A parametric study was conducted to compare the resistance to shear force provided by three surgical implantation techniques and three endplate designs for use with a polymeric lumbar intervertebral disk spacer. While under an axial load, the implant was pushed out laterally through the surgical window created for implantation. Force at 0.3 mm displacement, slope of the initial portion of the force-displacement graph, and maximum force were measured. The results indicate that implants with pegs, inclined planes, or domes on the surfaces of the disk will add significantly to the shear stability of the implant while maintaining the simplicity of a single part device.
