Why the study?
Does radiofrequency catheter ablation via the coronary sinus improve outcomes in patients with concealed WPW syndrome and posteroseptal accessory pathways?
Does radiofrequency catheter ablation via the coronary sinus improve outcomes in patients with concealed WPW syndrome and posteroseptal accessory pathways?
Radiofrequency catheter ablation via the coronary sinus for posteroseptal accessory pathways in concealed WPW syndrome can reduce retrograde conduction but may require numerous applications and fail to achieve complete pathway severance.
May support CS ablation feasibility in refractory concealed WPW; leaves open efficacy, safety, and durability in larger cohorts.
