Impella: pumps overview and access site management.

Impella: pumps overview and access site management. Minerva Cardioangiol. 2018 Apr 20;: Authors: Burzotta F, Russo G, Previ L, Bruno P, Aurigemma C, Trani C Abstract The Impella left ventricular support system consists of two main components: a family of different ventricular support catheters with a microaxial pump to be placed across the aortic valve and a single external controller (AIC) which is connected to activate and control the pump function. Four Impella left ventricular support catheters are available: Impella 2.5, Impella CP, Impella 5.0 and Impella LD. Impella 2.5 and Impella CP are designed for percutaneous peripheral insertion, have respectively a 12F and 14F maximal diameter at the pump level and are capable of providing up to 2.5 and 4.1 liters per minute, respectively. Impella 5.0 and Impella LD have 21F maximal diameter at the pump level and are designed for surgical insertion through, respectively, a peripheral artery (femoral or axillary) or the aorta. In high-risk percutaneous coronary interventions, the typical approach for Impella (2.5 or CP) is represented by the femoral artery or the axillary artery. The Impella CP or 5.0 are commonly selected for cardiogenic shock patients. The femoral approach represents the most adopted access site for percutaneous Impella insertion. Yet, it requires the presence of suitable aorto-iliac-femoral arterial axis for retrograde advancement of the Impella pump. The axillary art...
