Abstract
BACKGROUND: Despite clear clinical benefits, there is limited evidence regarding possible complications of the novel mechanical support device Impella. Aortic and mitral valve regurgitation or injury are rare but potential complications following implantation of the Impella device. METHODS: To evaluate valvular complications after the Impella device implantation, we have performed a comprehensive search of literature on multiple sites on this topic. RESULTS AND CONCLUSION: Ten case reports and one observational retrospective study were identified, with a total number of 19 patients identified. This article aims to draw attention to potential periprocedural complications relating to the Impella, in particular iatrogenic aortic and mitral valve injuries. Moreover, we have summarized our recommendations emphasizing the need for careful management and meticulous follow-up of these patients to avoid such potentially devastating complications.
