Echocardiographic evaluation of patients receiving a new left ventricular assist device: the Impella recover 100

Abstract

UNLABELLED: The aim of this study was to suggest a protocol for serial echocardiographic evaluations in patients undergoing circulatory support by a new miniaturized electric axial pump, the Impella recover 100 (IR 100). IR 100 is implanted through the ascending aorta into the left ventricle drawing blood from the left ventricle to the aorta. METHODS AND RESULTS: This protocol has been applied in eight patients receiving twelve IR 100 implants. Before implantation echocardiography was useful to rule out anatomic contraindications. During and after implantation echocardiography provided informations for correct positioning and evaluation of left ventricular filling necessary to optimize pump performance. During assistance it gave important informations to assess left and right ventricular function. CONCLUSION: Echocardiography has pivotal role in IR 100 management before, during and after implantation.
