Key result
A novel insulated-tip radiofrequency catheter (SMT) shows promising potential to improve ablation safety and efficacy, though translation to a human beating heart remains unclear.
A novel insulated-tip radiofrequency catheter shows promising early data that may improve the safety and efficacy of ablation procedures by directing energy exclusively toward target tissue.
Radiofrequency (RF) ablation has been the most widely employed energy source for catheter ablation to date. However, most of conventional RF ablation energy dissipates into the bloodstream before reaching the target tissue. Technology that conveys RF energy exclusively toward target tissue may potentially improve the quality, safety, and outcome of the RF ablation procedures. RF ablation using a novel insulated-tip catheter (SMT, Sirona Medical Technologies, Windsor, CT) may refine RF ablation in the future to minimize the risk of iatrogenic complications. Although it is still unclear whether the results of the SMT catheter can be translated to a human beating heart, the data for SMT catheter of this study are very promising.

Kotake et al. (2022) conducted an editorial in Catheter ablation. Insulated-tip radiofrequency catheter (SMT) vs. Conventional RF ablation was evaluated. A novel insulated-tip radiofrequency catheter (SMT) shows promising potential to improve ablation safety and efficacy, though translation to a human beating heart remains unclear.
