Summary

Catheter ablation is an established method of heart rhythm disturbances treatment. With an increasing number of ablations, it is imperative to further minimise the risks and maximise efficacy of this treatment. Intracardiac echocardiography is a cardiac imaging method made possible thanks to a steerable catheter inserted from the groin into the heart. ICE allows us to precisely visualise all cardiac structures and all material inserted in the heart, including diagnostic and ablation catheters. ICE improves safety and efficacy of ablation by monitoring of catheter position, ablation lesion formation, proximity to oesophagus, and presence of thrombi, needle position before transseptal puncture and generally by allowing a precise definition of an optimal place for ablation in atria and ventricles. Thanks to ICE, an operator sees what he or she is doing in real time. This makes ICE one of the most important tools in clinical electrophysiology.

Key words:
intracardiac echocardiography – catheter ablation – safety – efficacy
