Abstract
The clinical management of patients on Impella support requires multimodality monitoring and imaging. Upon intensive care unit admission, echocardiography is essential to ensure correct pump positioning/guide repositioning, to monitor acute myocardial infarction/device-related cardiac complications and to evaluate baseline left and right ventricular function. Over time, the echocardiographic assessment of myocardial viability has become an essential target for guiding mechanical circulatory support escalation and long-term strategies. The recognition and grading of any valvular dysfunction and damage in Impella patients are challenging, as the device interferes with the colour Doppler signal, and the loading conditions of the left ventricle are modified by the pump. Valvular disease in such patients is often secondary, and correct identification is pivotal for future therapeutic strategies. The emerging use of newer techniques, including speckle-tracking echocardiography, is of increasing interest in the imaging of critically ill patients.
