Summary

Right thoracotomy offers a viable alternative to repeated sternotomy for ventricular assist device (VAD) implantation. This approach may reduce complications associated with sternotomy in VAD patients.

Area of Science:

  • Cardiovascular Surgery
  • Medical Devices

Background:

  • Repeated sternotomy is often necessary for ventricular assist device (VAD) implantation.
  • Sternotomy carries risks of morbidity and mortality, particularly in patients with prior cardiac surgery.

Purpose of the Study:

  • To evaluate right thoracotomy as an alternative surgical approach for VAD implantation.
  • To assess the feasibility and safety of right thoracotomy for VAD procedures.

Main Methods:

  • Right thoracotomy was performed on 20 animals for bi-ventricular assist device (BVAD) and left ventricular assist device (LVAD) implantation.
  • Anatomical feasibility was tested on 7 human cadavers.
  • A clinical case of LVAD implantation via right thoracotomy was documented.

Main Results:

Related Experiment Videos

  • No procedure-related morbidity or mortality was observed in animal studies, except for one case of leg paralysis.
  • Cadaver studies identified optimal cannulation sites for BVAD implantation.
  • Successful LVAD implantation and explantation via right thoracotomy were achieved in a patient with cardiogenic shock.

Conclusions:

  • Right thoracotomy presents a safe and effective alternative to median sternotomy for VAD implantation.
  • This technique is suitable for patients requiring repeat sternotomy, including those with prior cardiac surgery, later transplantation, or mediastinal infections.
