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

Early inflation before aortic valve closure obstructs ventricular ejection, increasing afterload and potentially causing aortic valve damage.

Question 2

The Impella device provides hemodynamic support by:

Accepted Answer

Actively pumping blood from the left ventricle into the aorta

Answer

The Impella is an axial flow pump that aspirates blood from the left ventricle and ejects it into the ascending aorta, directly unloading the LV.

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

The inlet should be approximately 3.5 cm below the aortic valve in the LV to prevent suction events and ensure adequate support.

Question 4

A common complication of IABP use is:

Accepted Answer

Limb ischemia at the insertion site

Answer

Limb ischemia distal to the insertion site is a common vascular complication due to occlusion of the femoral artery by the IABP catheter.

Question 5

Which condition is a contraindication to Impella device use?

Accepted Answer

Mechanical aortic valve

Answer

A mechanical aortic valve is a contraindication because the Impella must cross the aortic valve, which would damage both the device and the prosthetic valve.
