Ablation characteristics
Group-A patients were treated with “conventional ablation” at the anatomic area of the slow pathway as described. This was successful in 24 patients (80%). In 4 patients, a left-sided approach was accomplished following unsuccessful right-sided slow pathway ablation. In 2 patients, additional lesions were needed in the roof of the proximal coronary sinus following unsuccessful ablation.Group-B patients were treated with ablation 2 mm higher in the septal area during fluoroscopy. This was successful in all patients without the need for additional lesions at other sites (p = 0.01 for the percentages of successful right-sided slow pathway ablation). The ablation characteristics of the two groups are highlighted in Table
