Original abstract
We report the case of a 30-year-old man who presented to our emergency department with rapid heart beat and a narrow complex tachycardia at a rate of 215 beats per minute. With the working diagnosis of Wolf-Parkinson-White syndrome with paroxysmal orthodromic tachycardias, we performed an electrophysiological study. In this examination, there was a para-Hisian accessory pathway with very fast, prognostically relevant conduction properties. In order to protect the His bundle that is located deeper in the tissue and to avoid a deeper lesion, we decided to use high-power short-duration ablation. This method, which was recently used in three-dimensional-controlled radiofrequency ablation of pulmonary veins, causes more superficial lesions in order to protect the surrounding tissue. In our case, using the high-power short-duration method, we were able to successfully ablate the para-Hisian accessory pathway, while protecting the His bundle near the ablation site.
