Patients
We
reviewed the procedural records of 105 consecutive patients who
underwent ablation of idiopathic OTVA between May 2020 and
October
2022 at our institutions. After exclusion, we reviewed the records of
the remaining 100 patients (48 men, mean age 62.77 ±14.10 years, and 52
women, mean age 60.00 ±13.15 years) who successfully underwent ablation
in either the RVOT or LVOT. No evidence of any structural heart disease
was observed. Before the procedures, written informed consent was
obtained from the patients, and antiarrhythmic drugs were discontinued
for at least five half-lives, except for amiodarone.
Electrophysiological studies and catheter ablation were performed under
local anesthesia.
