HPSD ablation: Procedure Efficiency
Multiple studies have shown that HPSD ablation technique is associated with shorter RF times and ablation times compared to LPLD technique (Table 1).29, 30, 32, 35, 37, 39 Figure 2 shows RF times in the two ablation techniques across different studies. Majority of the studies show significantly lower RF times with HPSD compared to LPLD ablation. Figure 3 shows fluoroscopy times in HPSD compared to LPLD ablation across six studies. Three out of the six studies show significantly lower fluoroscopy time with HPSD versus LPLD ablation.34-36 Thus, HPSD ablation potentially results in lower radiation use and shorter overall procedure duration compared to LPLD ablation. The reduction in procedure time is important because longer ablation times have been associated with worsening heart failure in patients with left ventricular dysfunction as a result of fluid overload from catheter irrigation and increased post-procedure cognitive dysfunction.44, 45
