Imaging of mechanical cardiac assist devices.

Ginat D, Massey HT, Bhatt S, Dogra VS - J Clin Imaging Sci (2011)

Bottom Line: Diagnostic imaging plays an important role in the assessment of patients with mechanical cardiac assist devices.Therefore, it is important for radiologists to be familiar with the basic components, function, and radiographic appearances of these devices in order to appropriately diagnose complications.The purpose of this pictorial essay is to review indications, components, normal imaging appearances, and complications of surgically and percutaneously implanted ventricular assist devices, intra-aortic balloon pumps, and cardiac meshes.

Figure 10: The IABP inflated within the aorta during diastole and deflated during systole.

Mentions: The Intra-aortic Balloon Pump (IABP) is a percutaneously inserted cardiac support device that exploits the principle of counterpulsation. Inflation and deflation of the balloon are synchronized to the patient's cardiac cycle. The IABP deflates during systole in order to decrease the afterload and inflates during diastole to increase coronary artery perfusion [Figure 10].[13] This produces a characteristic waveform on Doppler ultrasound [Figure 11].
