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.
