Catheter knot around the mitral valve apparatus: An exceptional complication of remote magnetic navigation

J Cardiovasc Electrophysiol. 2022 Jan;33(1):137-139. doi: 10.1111/jce.15313. Epub 2021 Dec 16.

Abstract

Remote magnetic navigation (RMN) is as safe and effective as manual navigation for catheter ablation of ventricular arrhythmias. This case is the first description of a soft-tip ablation catheter entrapment in the mitral valve apparatus during an RMN ablation procedure. The tight knot created by the catheter around a mitral valve chordae required surgical removal. This complication, which has never been reported before, highlights the need for closer fluoroscopic monitoring when performing catheter loops inside the ventricles when using the RMN system.

Keywords: cardiac surgery; catheter entrapment; catheter knot; complication; mitral valve apparatus; remote magnetic navigation.
