We identified 66 patients who underwent AVN ablation, out of which 31 were female. The patient was elderly with an average age of 73 years. Each patient had several comorbidities with a median of 5 per patient IQR(4, 5). The general characteristics of patients are summarized in table 1.
The indications were resistant atrial fibrillation in 74%, atrial flutter in 18%, and other atrial tachycardias in 8% of patients. Figure 1 shows the types of catheters used. The main catheters used were plain and CF catheters.
All ablation procedures were successful with no immediate post-procedure complications. Regarding lesion time, HPSD was significantly shorter compared to plain catheters by 403.42s[-631.67, -175.17]. Table 2 shows the exact difference in lesion time between catheters used.
