title: Clinical use of temporary percutaneous left ventricular assist devices.
abstract: BACKGROUND
  Temporary percutaneous left ventricular assist devices (TPLVAD) can be inserted and removed in awake patients. They substitute left ventricular function for a period of up to a few weeks and provide an excellent backup and bridge to recovery or decision.
  
  
  METHODS
  Retrospective analysis of 75 patients who received TPLVAD to treat cardiogenic shock (n = 49) or to facilitate high-risk percutaneous coronary intervention (PCI) (n = 26). Forty-two patients with cardiogenic shock and 16 patients with high-risk PCI received a TandemHeart and 7 patients and 10 patients, respectively, received an Impella Recover LP 2.5. Outcome and related complications up to 1 month are reported with reference to device depending function.
  
  
  RESULTS
  One-month survival was 53% in patients with shock and 96% in patients with PCI.
  
  
  CONCLUSIONS
  TPLVADs can support the failing heart with acceptable risk. Outcome is better in prophylactic use than in patients with cardiogenic shock.
