Focal arrhythmia ablation with multipolar mapping: Does it still make sense to stay off-grid?

Jay A Montgomery. J Cardiovasc Electrophysiol. 2020 Sep.

Abstract

Multipolar mapping (MPM) has primarily been studied in complex arrhythmia substrates or reentrant circuits. Chieng et al. use a case-control design to compare MPM and point-by-point mapping with an ablation catheter for focal atrial and ventricular tachycardias, showing reduced procedure times and earlier electrograms in the MPM group but no difference in clinical outcomes. It is plausible that faster mapping and better delineation of earliest signals may translate to improved clinical outcomes if studied in a randomized trial in a larger population. Future MPM systems will guide the operator toward the focus in real-time and may even triangulate the source in three dimensions, giving an estimate of depth within the myocardium or likely focus in the opposite chamber.

Keywords: atrial tachycardia; electroanatomic mapping; multipolar mapping; omnipolar mapping; ventricular tachycardia.
