CTICasesImpella Malposition
Imaging findings
CT chest shows an Impella ventricular assist device with the distal pigtail loop in the left ventricle. However, the inlet cage and cannula are positioned too proximally, sitting directly at the level of the aortic valve leaflets.
Key takeaways
Proper positioning of the Impella catheter requires the inlet area to sit 3-4 cm below the aortic valve. Proximal migration of the catheter can cause the inlet to compress or create suction against the aortic valve leaflets, leading to device dysfunction or valvular injury.
