Understanding Radiofrequency Ablation in the era of Contact Force Sensing


In this webinar, Dr Wright, an expert in real-world contact force ablation will discuss and provide an overview of the contact force radiofrequency ablation technique and its effect on lesion size.

Despite the widespread use of RF ablation in daily practice, it is perhaps surprising how much is still not understood about the basics of the biophysics underpinning RF ablation. Contact is fundamental to successful ablation, yet it is only in the last few years that we now have the tools to measure contact while performing ablations.

How we interpret this data among the myriad of factors that affect lesion formation is complicated by the endpoints that we have in clinical medicine. Recurrence of AF is a blunt tool, and even acute recurrence of conduction is relatively poor when we are trying to achieve permanent contiguous transmural lesions.

Learning objectives

> How irrigation rates and power delivery can be optimised.
> A historical overview.
> An outline on the role of contact force with a look at some real life case studies to prove the data.
> It will also consider the role of contact force in the future.
