Axillary Impella combined with Protek Duo enables viable biventricular support and patient ambulation.
Case Report (n=1)
The combination of Impella CP and Protek Duo provides a viable percutaneous option for biventricular support that allows for patient ambulation.
May offer percutaneous biventricular support option in select patients; leaves open safety, efficacy, and selection criteria for broader use.
This is the first reported case of full biventricular mechanical circulatory support with the combination of Impella and Protek Duo, which is a dual-lumen cannula inserted via the right internal jugular vein, with its proximal inflow lumen positioned in the right atrium and distal lumen positioned in the main pulmonary artery. These lumens are connected with the paracorporeal TandemHeart pump allowing flows up to 5 L/min. The alternative percutaneous option for right ventricular support is the Impella RP (Abiomed), which has to be placed in the femoral vein, preventing ambulation. The axillary and internal jugular vein positions for devices are probably less prone to infection compared to the femoral area. The combination of an Impella inserted via the axillary artery with the Protek Duo is a viable option, allowing ambulation while providing biventricular support.

Patel et al. (2019) conducted a case report in Need for biventricular mechanical circulatory support (n=1). Combination of Impella and Protek Duo Plus TandemHeart was evaluated on Feasibility of biventricular support allowing ambulation. The combination of an Impella inserted via the axillary artery with the Protek Duo is a viable option for providing biventricular support while allowing patient ambulation.
