title: Real-world use of the Impella 2.5 circulatory support system in complex high-risk percutaneous coronary intervention: the USpella Registry.
abstract: OBJECTIVE
  We report on the real-world, multicenter experience of the Impella 2.5 circulatory support system during high-risk PCI, a subset of the larger USpella Registry.
  
  
  BACKGROUND
  Standard of care for most patients with compromised ventricular function with multivessel or high-risk coronary lesions has been coronary artery bypass grafting. In poor operative candidates, high-risk PCI is increasingly considered, despite an increased risk for periprocedural hemodynamic compromise.
  
  
  METHODS
  175 consecutive patients who underwent high-risk PCI with prophylactic support of the Impella 2.5 were evaluated. The primary safety endpoint was the incidence of major adverse cardiac events (MACE) at 30 days. Secondary endpoints included safety and efficacy related to the device and patient outcomes, including survival at 12 months.
  
  
  RESULTS
  Overall angiographic revascularization was successful in 99% of patients and in 90% of those with multivessel revascularization, resulting in a reduction of the mean SYNTAX score post-PCI from 36 ± 15 to 18 ± 15 (P < 0.0001) and an improvement of the ejection fraction (from 31 ± 15% to 36 ± 14%, P < 0.0001). In 51% of patients, the functional status improved by one or more NYHA class (P < 0.001). At 30-day follow-up, the rate of MACE was 8%, and survival was 96%, 91%, and 88% at 30 days, 6 months, and 12 months, respectively.
  
  
  CONCLUSIONS
  The use of Impella 2.5 in high-risk PCI appeared feasible and safe in the real-world setting. The utilization of the Impella 2.5 was successful, resulting in favorable short- and midterm angiographic, procedural and clinical outcomes.
