Adverse Events of Percutaneous Microaxial Left Ventricular Assist Devices-A Retrospective, Single-Centre Cohort Study.

Worldwide, the left ventricular assist device Impella (Abiomed, Danvers, MA, USA) is increasingly implanted in patients with acute cardiogenic shock or undergoing high-risk cardiac interventions. Despite its long history of use, few studies have assessed its safety and possible complications associated with its use. All patients treated with a left-sided Impella device at the University Hospital of Basel from 1 January 2011 to 31 December 2019 were enrolled.
