Initial procedure
Four patients (67%) had a recurrence and 2 (33%) had a failed initial procedure. The main reasons leading to a repeated procedure seemed to be poor contact (n=2, 33%) and limited application (n=2, 33%) due to proximity of the AV node. Overall, this location correlated with the lowest energy delivery and the lowest mean temperatures (mean power 25.3±8.6 Watts and mean temperatures 47.7±6.6°C).
