Why the study?
Does a box lesion encircling the four pulmonary veins achieve isolation in a patient with atrial fibrillation and a common inferior trunk?
Does a box lesion encircling the four pulmonary veins achieve isolation in a patient with atrial fibrillation and a common inferior trunk?
A box lesion encircling all four pulmonary veins is a feasible ablation strategy for atrial fibrillation in patients with a common inferior trunk variant.
