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
