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.
这是首例报道的使用Impella和Protek Duo联合进行全心室机械循环支持的病例，Protek Duo是一种经右颈内静脉插入的双腔插管，其近端流入腔位于右心房，远端腔位于主肺动脉。这些腔与体外串联式心脏泵相连，可实现高达5升/分钟的流量。右心室支持的另一种经皮选择是Impella RP（Abiomed公司），它必须放置在股静脉中，这会妨碍患者行走。与股部区域相比，将设备放置在腋窝和颈内静脉位置可能不太容易发生感染。经腋动脉插入的Impella与Protek Duo联合使用是一种可行的选择，既能在提供双心室支持的同时让患者行走。
