Summary

This study shows that a temporary right ventricular assist device, implanted via the jugular vein, is safe and feasible for coronary bypass grafting. It improves hemodynamic stability during complex posterior anastomosis procedures.

Area of Science:

  • Cardiovascular Surgery
  • Medical Devices
  • Minimally Invasive Procedures

Background:

  • Temporary right heart bypass enhances hemodynamic stability and safety in beating heart revascularization.
  • Percutaneous right ventricular support is an emerging technique for cardiac surgery.

Purpose of the Study:

  • To evaluate the feasibility and safety of a percutaneously implanted right ventricular assist device (RVAD) using the right jugular vein.
  • To assess the utility of RVAD in facilitating coronary artery bypass grafting (CABG) without cardiopulmonary bypass.

Main Methods:

  • The study utilized the A-Med jugular coaxial cannula, a percutaneous device for right heart bypass.
  • Blood was drained from the right heart and returned to the pulmonary artery via a microcentrifugal pump.

  • The device was implanted percutaneously through the right internal jugular vein in 10 patients.

    • Main Results:

    • Right heart support via percutaneous jugular access was feasible in all 10 patients without complications.
    • A total of 27 coronary anastomoses were successfully performed with the RVAD in place.
    • Significantly higher arterial pressure was maintained during posterior and posterolateral anastomosis procedures with RVAD support.

    Conclusions:

    • Percutaneous jugular access for temporary right heart support is safe and feasible.
    • This technique facilitates posterior and posterolateral coronary bypass grafting.
    • RVAD offers a viable option for hemodynamic support in beating heart revascularization.
