Short-term Results of Heartmate 3 Ventricular Assist Device Implantation for End-Stage Heart Failure.
OBJECTIVE
To report our initial experience with Heartmate 3 ventricular assist device (HM3) in cases with end-stage heart failure (ESHF).


METHODS
Charts of 8 ESHF patients who underwent HM3 implantation in our clinic from January to June 2016 (group 1) and 16 patients who underwent HM2 implantation during 2015 (group 2) were reviewed retrospectively. Demographics as well as pre- and early postoperative medical data were noted and statistically analyzed between the 2 groups.


RESULTS
No statistical difference was found in age or sex distribution between groups (P > .05). Mean Interagency Registry for Mechanically Assisted Circulatory Support scores were 2.13 ± 0.99 and 3.38 ± 0.72 in groups 1 and 2, respectively (P = .020). Mean cardiopulmonary bypass time, and chest tube drainage fluid volume and blood product requirement during intensive care unit (ICU) stay were 64.0 ± 13.9 minutes, 1,112.5 ± 516.7 mL, and 318.8 ± 271.2 mL, respectively, in group 1 and 89.0 ± 33.3 minutes, 2,081.3 ± 1,696.0 mL, and 1,118.8 ± 1,010.8 mL in group 2 (P = .027, P = .019, and P = .040, respectively). Need for surgical revision and early mortality were not evident for group 1, although 4 cases (25.0%) required revision surgery, and early mortality was seen in 3 cases (18.8%) in group 2 (P = .121 and P = .190, respectively). Mean durations of ICU stay and total postoperative hospitalization were 5.9 ± 2.0 and 18.3 ± 5.5 days, respectively in group 1 and 6.2 ± 4.3 and 18.0 ± 6.9 days in the surviving 13 patients of the group 2 (P = .645 and P = .697, respectively).


CONCLUSIONS
With its shorter implantation time and reduced blood product requirement in the early postoperative period, the HM3 system was found to be safe and effective in ESHF treatment.
