Objectives:
This study aimed to report the clinical outcomes of continuous flow left ventricular assist device implantation in end-stage chronic heart failure patients with a history of surgical left ventricular restoration.
Methods:
We retrospectively identified 190 patients undergoing continuous flow left ventricular assist device implantation at our center from November 2007 to April 2020. In total, six patients underwent continuous flow left ventricular assist device implantation after various types of surgical left ventricular restoration procedures, including endoventricular circular patch plasty (n = 3), posterior restoration procedure (n = 2), and septal anterior ventricular exclusion (n = 1).
Results:
Continuous flow left ventricular assist device (Jarvik 2000, n = 2; EVAHEART, n = 1; HeartMate II, n = 1; DuraHeart, n = 1; HVAD, n = 1) was successfully implanted in all patients. During a median follow-up of 48 months (interquartile range, 39-60 months; censoring heart transplantation), no death was documented, which means that overall survival after left ventricular assist device implantation was 100% at any time point. Finally, three patients received heart transplantation (waiting time: 39, 56, and 61 months, respectively) and the other three patients are still awaiting heart transplantation (waiting time: 12, 41, and 76 months, respectively).
Conclusions:
In our series, continuous flow left ventricular assist device implantation after surgical left ventricular restoration was safe and feasible, even if an endoventricular patch was used, and effective for bridge to transplant strategy.
