Novel Technique for Percutaneous Retrieval of a U-kinked Impella Catheter.

Abstract

We present a new technique for percutaneous retrieval of a U-kinked displaced Impella catheter. First we used the hooker from the left femoral artery to snare the catheter tip. Both catheter and hooker were pulled down simultaneously from 2 opposite sites until the U-kinking sat astride the aortic bifurcation. Finally the loop was straightened by pulling both catheter and hook. Once unfolded the hook was released, and the catheter was retrieved easily from the right femoral artery. This technique is highly reproducible because of several advantages. It is easy to perform, takes a short time, does not require special devices, and is not expensive.
