Zusammenfassung:Given the need for the creation of high-quality ablation lesions, a possible reason for the recurrence of AVNRT may be unstable contact between the catheter tip and the target tissue during RF energy delivery. Factors contributing to such instability could include increased respiratory variability and body movements due to discomfort during the RF energy delivery and sometimes a prominent Eustachian ridge preventing placement of the ablation catheter on the atrial septum. [...]although most recurrent cases required reablation in the high RIE region, it cannot be ruled out that mapping and ablation from the left atrial septum may have been effective in most cases of recurrence.
