Abstrakt: Aims: Pre-operative or post-operative heart failure (HF) and cardiogenic shock of various natures frequently remain refractory to conservative treatment and require mechanical circulatory support. We report our clinical experience with large Impella systems (5.0 or 5.5; i.e. Impella 5+) (Abiomed Inc., Boston, USA) and evaluate the parameters that determined patient outcome.
Methods and Results: The initial 50 cases of Impella 5+ implanted for acute HF between November 2018 and August 2020 at a single centre were enrolled in this study. Data, including preoperative characteristics, perioperative clinical course information, and post-operative outcomes, were retrospectively collected from the hospital data management and quality assurance system. Descriptive and univariate analyses were performed. Among the 49 patients in this study, 28 (56.0%) survived in the first 30 days post-operatively, and 3 died of non-cardiac reasons later. In-hospital mortality was significantly higher in patients with biventricular failure [P < 0.01, odds ratio (OR) 5.63] or dilated cardiomyopathy (DCM) (P = 0.02, OR 15.8), whereas ischaemic cardiomyopathy (ICM) was associated with lower mortality (P = 0.03, OR 0.24). Interestingly, the mortality was comparable between the 'solo' Impella group and the veno-arterial extracorporal membrane oxygenation (va-ECMO) plus Impella (ECMELLA) group, despite the severity of the patients' profile in the ECMELLA group ('solo' vs. ECMELLA; 55.6% vs. 52.6%, P = 1.00). All patients who received an additional temporary right ventricular assist device (tRVAD) were successfully weaned from va-ECMO.
Conclusions: Our results suggest that biventricular failure and DCM are predictors of higher mortality in patients with Impella. Considering the pathophysiology of HF, implantation of a large Impella system seems to be promising, especially for ICM patients. The large Impella system might be more effective for better prognosis of patients under va-ECMO, and combination therapy with tRVAD seems to be a promising strategy for early weaning from va-ECMO.
