    Background: Treating heavily calcified vessels is a challenging task in patients with an impaired left ventricular ejection fraction (LVEF). Percutaneous mechanical circulatory support (pMCS) is increasingly used in patients in high-risk PCI (HRPCI). In this retrospective registry, we investigated 25 patients undergoing a protected HRPCI receiving either intravascular lithotripsy (IVL+pMCS; n=11) or rotational atherectomy (RA+pMCS; n=14). Primary Endpoint was defined as periinterventional hemodynamic stability. Secondary endpoint was defined as major adverse cardiac events (MACE). Results: Patients in the IVL+pMCS group had a significantly higher mean arterial pressure (MAP) at the end of the procedure (p=0.04). However, the ∆-change in MAP was not significant (-12mmHg (±20.3) vs. -16.1mmHg (±23.9) p=0.709). The proportion of patients requiring postinterventional catecholamines was significantly lower in the IVL+pMCS group (p=0.02). The ∆ change in Syntax Score were not significant between groups (IVL+pMCS -22 (±5.8) vs.RA+pMCS -21.2 (±7.6), p=0.783). MACE did occur less in the group of IVL+pMCS (0% vs. 20%, p=0.046). Cox regression analysis revealed that pMCS insertion as a bailout strategy (p=0.001) and the occurrence of slow-reflow were associated with a higher risk for in-hospital death (p=0.021). Conclusions: In our cohort patients in the IVL+pMCS group were hemodynamical more stable which led to a lower rate of catecholamine usage. pMCS as a bailout strategy and the occurrence of the slowreflow phenomenon were associated with in-hospital death.
