Background:
Implantation of a HeartMate II or a Jarvik 2000 FlowMaker left ventricular assist system (LVAS) usually involves a mid-line sternotomy and the use of cardiopulmonary bypass (CPB). In patients with numerous co-morbid conditions, however, surgical trauma may be minimized by implanting the LVAS via a minimally invasive approach, preferably without CPB.
Methods:
In 6 patients with end-stage heart failure and other serious co-morbidities, we implanted a HeartMate II (n = 3) or a Jarvik 2000 FlowMaker (n = 3) LVAS via a right mini-thoracotomy and a left sub-costal incision. Patients included 3 men and 3 women with a mean age of 41 years. In 3 cases, the LVAS was implanted without CPB.
Results:
After a mean follow-up period of 6 months, 5 patients are alive and well and on the transplant waiting list. Seven months after LVAS implantation, the remaining patient developed a hemorrhagic stroke necessitating Jarvik 2000 replacement with a new pump of the same type.
Conclusions:
In this small series, the combined sub-costal and mini-thoracotomy incision proved safe and technically feasible. It may be useful for other LVAS candidates who have serious co-morbidities that preclude traditional implant operations.
