Why the study?
Does wide antral pulmonary vein isolation prevent total atrial tachyarrhythmia recurrence compared to ostial pulmonary vein isolation?
Does wide antral pulmonary vein isolation prevent total atrial tachyarrhythmia recurrence compared to ostial pulmonary vein isolation?
Wide antral pulmonary vein isolation provides better long-term freedom from atrial tachyarrhythmia recurrence compared to the ostial approach.
Supports wide antral PVI for long-term arrhythmia freedom; leaves open confirmation in randomized trials.
Our primary finding is that PVI performed with a wide antral approach is more effective than ostial PVI in achieving freedom from total atrial tachyarrhythmia recurrence at long-term follow-up.
