The Impella (Abiomed, Danvers, MA, USA) has become an important adjunct treatment modality in bridging patients with end‐stage heart failure to recovery or orthotopic heart transplantation (HTx). We compared the outcome of patients directly bridged to HTx with the Impella 5.0 versus patients without mechanical circulatory support (MCS). Patients with no previous sternotomy or MCS, who were transplanted between September 2014 and March 2019 were included in this retrospective analysis. Impella 5.0 was implanted using surgical access and transesophageal echocardiography guidance. Forty‐two out of 155 transplanted patients fulfilled the insertion criteria. Eight (19%) were bridged with Impella 5.0 to HTx. Recipient and donor baseline characteristics were comparable in both groups. There were no significant differences in survival between the groups at 30‐day (94% no MCS vs. 87.5% Impella group, P = .47) or 6 months (94% vs. 87.5%, P = .51). Patients on Impella 5.0 showed a significant recovery of hemodynamic parameters and end‐organ function. Average duration of support to HTx was 16 ± 17 days. Impella 5.0, when used in suitable patients in a timely fashion can be a good strategy for bridging patients to HTx. The axillary approach allows for early extubation and mobilization. Outcomes of patients bridged to HTx with Impella 5.0 in acute cardiogenic shock are comparable to those of patients with no MCS.

Right ventricular failure is one of the most common complications encountered after left ventricular assist device implantation and heart transplantation. It has been reported to have an incidence up to 30%. It increases morbidity and short‐term mortality. Impella RP is a small pump that can provide up to 4L/min of flow. We analyzed all the patients with right ventricular failure that were treated with Impella RP in our institution. The Impella RP was implanted percutaneously in the catheterization laboratory guided by fluoroscopy. Overall, 7 patients required the implantation of an Impella RP due to right ventricular failure: 2 after long‐term LVAD, 3 presented with acute right ventricular failure immediately after LVAD implantation, and 2 needed it after heart transplantation. Regarding complications, we report 2 patients with hemolysis. Hemodynamic parameters as well as end‐organ perfusion and inotropic requirements improved after the insertion of the Impella. Overall, 30‐day survival is 58%. Median time of support was 9 (5–19) days. RV failure is one of the most challenging complications after LVAD implantation and heart transplantation. The major challenge is the timing of implantation. The minimally invasive nature of the Impella RP facilitates de‐escalation of treatment and paves the road to recovery. Impella RP proved useful in facilitating ECMO wean. Used in a prompt manner alongside the ease of implantation and the minimal rate of complications, Impella RP seems to be an appropriate device to tackle RV failure providing enough flow to allow for recovery or escalation decision‐making.
