What does this research mean for the field?

In patients with idiopathic right ventricular outflow tract ventricular tachycardia (RVOT-VT), males exhibit longer QRS widths while females have lower right ventricular mean voltages, although catheter ablation outcomes are similar across genders.

Implication

Gender differences in RVOT-VT electrophysiology warrant sex-stratified mapping in future studies; should not yet change ablation practice.

Structured PICO

Are there gender differences in electrophysiological characteristics and catheter ablation outcomes in patients with idiopathic RVOT-VT?

Population

93 patients with idiopathic ventricular tachycardia originating from right ventricular outflow tract (RVOT-VT), mean age 38.7+/-15.5 years, 30 males.

Outcome

Electrophysiological characteristics (QRS width, right ventricular mean voltage, low voltage zone) and catheter ablation outcomes (acute success rate, repeated ablation rate, VT recurrence rate)surrogate

There are significant gender differences in the electrophysiological characteristics of idiopathic RVOT-VT, although catheter ablation outcomes appear similar between men and women.
