Currently, there are no data on the use of mechanical circulatory support (MCS) in patients without severely depressed left ventricular ejection fraction (LVEF) during high-risk percutaneous coronary intervention (PCI). We analyzed data from the global catheter-based ventricular assist device (cVAD) registry on the clinical use of MCS in high-risk PCI in patients without severely depressed LVEF, defined as LVEF > 35%. Patients without cardiogenic shock from the catheter-based ventricular assist device registry, who underwent elective or urgent PCI with an Impella 2.5 or Impella CP, were included. Patients who received MCS after the start of the PCI were excluded. A total of 891 patients were included, of whom 661 had LVEF ≤ 35% and 230 had LVEF > 35%. Patients with LVEF > 35% compared with patients with LVEF ≤ 35% were older (72.12 ± 11.70 years vs 68.68 ± 11.01 years; p 35%, this selected group of patients had severe co-morbidities and complex angiographic features; hence, PCI with hemodynamic support was deemed necessary. In addition, PCI with elective MCS was feasible and safe in this patient population.
