RESULTS
As recent evidence still remains scarce due to the novelty of the device and potential underreporting, we have reviewed literature in order to highlight potentially life-threatening valvular complications. Ten case reports and one observational retrospective study were identified, with a total number of 19 patients identified, reporting periprocedural complications of either aortic or mitral regurgitation related to the Impella device. The characteristics of included studies and case reports are presented in Table 1.
