Are arrhythmia recurrences rare when the site of radiofrequency ablation of the slow pathway is medial or anterior to the coronary sinus os?
AVNRT recurrences are rare (1%) when slow pathway RF ablation is performed in medial or anterior locations at the tricuspid annulus, rather than in inferoposterior sites, whereby a higher (13%) recurrence rate has been previously noted.
Our findings suggest that soluble cell adhesion molecules may have a role in the pathogenesis and progression of OHSS.
