Impella percutaneous left ventricular assist device<\/span><\/h2>\n

Impella percutaneous left ventricular assist device: Impella LP 2.5 manufactured by Abiomed-Impella CardioSystems GmbH, Aachen, Germany is percutaneous left ventricular assist device. It uses a catheter-based miniaturized rotary blood pump, that is placed retrogradely through the aortic valve. The microaxial pump aspirates blood from the left ventricle and expels it to the ascending aorta with a maximal flow of 2.5 L\/min. It may be used to tide over a crisis situation in patients with cardiogenic shock of reversible etiology. Efficacy Study of LV Assist Device to Treat Patients With Cardiogenic Shock (ISAR-SHOCK) using this device has been completed. It was a comparison between in intra aortic balloon pump (IABP) and Impella LP 2.5 left ventricular assist device in acute coronary syndrome with cardiogenic shock. A report of the trial in the November 4, 2008 issue of JACC [1] mentions that the cardiac index (CI) after 30 minutes of support was significantly increased in patients with the Impella LP2.5 compared with patients with IABP (Impella: CI = 0.49 \u00b1 0.46 l\/min\/m2; IABP: CI = 0.11 \u00b1 0.31 l\/min\/m2; p = 0.02). Mortality benefit has not been demonstrated yet [2].<\/p>\n

Recover\u00ae LP 2.5 is a minimally invasive ventricular unloading catheter which can introduced percutaneously through the femoral artery and provides a flow of 2.5 litres per minute. Recover\u00ae LP 5.0 is a ventricular unloading catheter, which is placed via a femoral artery cut-down into the left ventricle and can support a flow of 5 litres per minute.<\/p>\n
