Procedural parameters in patients undergoing radiofrequency catheter ablation with zero fluoroscopy or near-zero fluoroscopy approach for idiopathic ventricular arrhythmias originating from the aortic sinus cusp

Parameter	ZF approach	NOX approach	P
Procedure time, min	58.0 [45.0–75.0]	75.0 [65.0–89.8]	0.002
Fluoroscopy time, min	0.0 [0.0–0.0]	6.0 [2.0–11.8]	< 0.001
RFA delivery time, min	6.2 [3.2–8.8]	5.1 [3.4–11.3]	0.93

Continuous variables are expressed as medians [Q1–Q3]
