Prevalence and Severity of Aortic Regurgitation Due to a Percutaneous Left Ventricular Assist Device (Impella 5.0): A Retrospective Observational Study
Authors' conclusion
The authors revealed a high prevalence of AR during Impella 5.0 support in patients with no spontaneous cardiac output. Moreover, 31.6% of patients had moderate AR.
