Minimally invasive implantation of left ventricular assist systems (LVAS) using a combined mini-thoracotomy and sub-costal incision is safe and feasible. This approach may benefit patients with serious co-morbidities unsuitable for traditional surgery.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Procedures
  • Mechanical Circulatory Support

Background:

  • Traditional left ventricular assist system (LVAS) implantation requires sternotomy and cardiopulmonary bypass (CPB).
  • Patients with significant co-morbidities may not tolerate extensive surgical trauma.
  • Minimally invasive approaches can reduce surgical burden.

Purpose of the Study:

  • To evaluate the safety and feasibility of a minimally invasive LVAS implantation technique.
  • To assess an approach that potentially avoids cardiopulmonary bypass in high-risk patients.

Main Methods:

  • Six patients with end-stage heart failure and co-morbidities underwent LVAS implantation (HeartMate II or Jarvik 2000).
  • A combined right mini-thoracotomy and left sub-costal incision was utilized.

  • Three implants were performed without cardiopulmonary bypass.

    • Main Results:

    • Five of six patients survived with good outcomes and are awaiting heart transplantation.
    • One patient experienced a hemorrhagic stroke requiring device replacement.
    • The mean follow-up period was six months.

    Conclusions:

    • The combined sub-costal and mini-thoracotomy incision for LVAS implantation is safe and technically feasible.
    • This approach offers a viable alternative for LVAS candidates with severe co-morbidities.
    • Further studies are warranted to confirm these findings in larger cohorts.
