Registered Cardiovascular Invasive Specialist (RCIS) Practice Test

What is the main function of the percutaneous Impella device?

1. Increases blood pressure

2. Evacuates blood from the left ventricle to the ascending aorta

3. Monitors heart rhythm

4. Hydrates the myocardium

The correct answer is: Evacuates blood from the left ventricle to the ascending aorta

The main function of the percutaneous Impella device is to evacuate blood from the left ventricle into the ascending aorta. This device is designed to provide temporary mechanical circulatory support for patients experiencing severe heart failure or cardiogenic shock. By drawing blood from the left ventricle and ejecting it into the aorta, the Impella device helps improve cardiac output, reduce the workload on the heart, and ensure better perfusion to vital organs. Understanding the role of the Impella device is crucial in clinical settings where traditional heart function may be compromised. Its ability to support the heart's function effectively can be pivotal in managing critical care patients, especially during procedures or while other treatments are initiated. This highlights how mechanical support devices can play an essential role in maintaining hemodynamic stability in urgent medical circumstances.
