RCIS Intra-Aortic Balloon Pump and Mechanical Circulatory Support 2

Question 1

Early IABP inflation (before the dicrotic notch) results in:

Accepted Answer

Increased afterload and aortic valve obstruction

Answer

Improved diastolic augmentation

Answer

Decreased heart rate

Answer

Improved coronary perfusion

Question 2

The Impella device provides hemodynamic support by:

Accepted Answer

Actively pumping blood from the left ventricle into the aorta

Answer

Augmenting diastolic aortic pressure

Answer

Oxygenating blood through a membrane

Answer

Reducing heart rate to decrease oxygen demand

Question 3

For correct Impella CP positioning, the inlet area of the device should be located:

Accepted Answer

3.5 cm below the aortic valve in the left ventricle

Answer

In the left atrium

Answer

At the mitral valve

Answer

In the left ventricular apex

Question 4

A common complication of IABP use is:

Accepted Answer

Limb ischemia at the insertion site

Answer

Pulmonary embolism

Answer

Hyperkalemia

Answer

Aortic stenosis

Question 5

Which condition is a contraindication to Impella device use?

Accepted Answer

Mechanical aortic valve

Answer

Cardiogenic shock

Answer

Severe aortic stenosis

Answer

Low cardiac output state

Question 6

Late IABP deflation (deflation during systole) causes:

Accepted Answer

Increased afterload

Answer

Improved ventricular unloading

Answer

Decreased diastolic augmentation

Answer

Improved stroke volume

Question 7

The TandemHeart device provides left heart support by:

Accepted Answer

Withdrawing oxygenated blood from the left atrium via a transseptal catheter and pumping it to the femoral artery

Answer

Withdrawing blood from the left ventricle and returning it to the aorta

Answer

Inflating during diastole to augment coronary perfusion

Answer

Providing extracorporeal oxygenation
