title: Percutaneous Mechanical Ventricular Support in Acute Cardiac Care: A UK Quaternary Centre Experience Using 2.5L, 3.8L and 5.0L Impella Catheters.
abstract: OBJECTIVE
  The Impella is a percutaneous ventricular assist device. The majority of published data describes the 2.5L and 5.0L devices, and little data is available for the newer 3.8L device. We examined the indications and outcomes from our single-centre "real-world" registry at The Queen Elizabeth Hospital, Birmingham, UK, using all three pump sizes.
  
  
  RESULTS
  Records from all patients who underwent attempted Impella-assisted procedures at our centre were examined retrospectively. Impella implantation was attempted in 49 patients (mean age 72 ± 13 years; 80% male) and was successful in 48 (98%). 45 patients underwent high-risk percutaneous coronary intervention (PCI), one patient underwent balloon aortic valvuloplasty and 3 patients had Impella as a bridge to cardiac transplantation. The 2.5L and 3.8L devices were used in 36 (75%) and 11 (23%) patients, respectively, while one patient (2%) had the 5L device. Vascular complications occurred in only one patient (2%) and stroke and peri-procedural myocardial infarction occurred in one patient (2%), while in-hospital mortality was 20% (10/49).
  
  
  CONCLUSIONS
  In this large real-world registry, we have demonstrated the safety and feasibility of the Impella device for a wide range of indications. This includes the first series of the 3.8L device which provides superior support with no increase in vascular complications.
