Key result
Impella 5.0/5.5 implantation via the innominate artery provides an alternative access route for mechanical circulatory support when axillary or subclavian arteries are unsuitable.
Innominate artery access provides a viable alternative for Impella 5.0/5.5 implantation when standard upper extremity access is unsuitable, facilitating early rehabilitation and potentially improving survival in cardiogenic shock.
When axillary/subclavian arteries are not suitable because of size or anatomy, alternative access for the Impella pump 5.0/5.5 via the innominate artery allows circulatory support and eventually de-escalation from VA-ECMO to isolated left-side support. Moreover, less invasive surgery without the need to open the pericardium reduces the risk of RV dysfunction and bleeding. Finally, upper body strategies allow early rehabilitation during support, which is associated with improved survival in cardiogenic shock.

Bertolin et al. (2022) conducted a review in Cardiogenic shock requiring temporary mechanical circulatory support. Impella 5.0/5.5 Implantation via Innominate Artery was evaluated. Impella 5.0/5.5 implantation via the innominate artery provides an alternative access route for mechanical circulatory support when axillary or subclavian arteries are unsuitable.
