Implication

Retrospective case series examines hemodynamic effects of Impella 5.5 in high-risk CABG patients, suggesting feasibility.

Key Points

  • This research aims to evaluate the outcomes of using Impella 5.5 in patients undergoing coronary artery bypass grafting (CABG) with left ventricular dysfunction.
  • Single-center retrospective case series of 16 patients undergoing isolated CABG with Impella 5.5 support from July 2020 to May 2024.
  • Clinical characteristics and procedural details were gathered from electronic medical records after surgery.
  • Patients with certain exclusions were observed, and outcomes were assessed post-implantation.
  • Eighty-one percent of patients (13 out of 16) were successfully weaned from the device after CABG.
  • Overall in-hospital mortality was 18.8%, with 3 patients dying during hospitalization, including 1 after device explantation.
  • Rhythm complications were noted in 56.3% of patients, most commonly rapid atrial fibrillation (31.3%).
