Key result
Patient age was an independent predictor of successful radiofrequency catheter ablation for idiopathic ventricular arrhythmias (OR 0.97), with distinct gender and age differences observed according to the site of arrhythmia origin.
Why the study?
Does the site of origin of idiopathic ventricular arrhythmias correlate with gender, age, and ablation success rate in patients undergoing catheter ablation?
Population
625 consecutive patients with symptomatic, drug-resistant idiopathic ventricular arrhythmias, mean age 54 ±…

Age and origin site may inform ablation counseling; leaves open prospective validation of these associations.

Effect estimate: OR 0.97 (95% CI 0.95-0.99)
p-value: p=0.007
Idiopathic ventricular arrhythmias exhibit distinct gender and age distributions based on their site of origin, with RVOT-VA being more common in women and having a higher ablation success rate than LVOT-VA.
Tanaka et al. (2011) conducted an observational in Idiopathic ventricular arrhythmias (n=625). Radiofrequency catheter ablation was evaluated on Successful catheter ablation (patient age as predictor) (OR 0.97, 95% CI 0.95-0.99, p=0.007). Patient age was an independent predictor of successful radiofrequency catheter ablation for idiopathic ventricular arrhythmias (OR 0.97), with distinct gender and age differences observed according to the site of arrhythmia origin.
