Catheter ablation of accessory pathways can be challenging depending on the location of these pathways, and accessory pathways are rare through the aortic cusps. We report a patient who underwent radiofrequency catheter ablation for manifestation of a left anterior accessory pathway from the left coronary sinus of Valsalva near the aortic–mitral continuity. Anterior accessory pathways can be safely and effectively ablated from the aortic cusps with favorable long-term outcomes.

Abstract Background In accessory pathway-related supraventricular tachycardia ablation, coronary sinus (CS) ablation has received more and more attention, but there are no accurate criteria for catheter selection. Objectives We intended to develop a new method for the reasonable selection of electrode for coronary sinus ablation via assessing the relationship between the accessory pathway (AP) potential and time of successful ablation. Methods Among the patients who had detected the bypass potential during radiofre-quency ablation between 1/1/2015 and 12/31/2019, 30 patients underwent radiofrequency catheter ablation (RFCA) in CS. The relationship between AP potential and time of successful ablation was analyzed. Results In CS ablation, the median baseline amplitude of the AP potentials in patients with successful Temperature control catheter (TCC) ablation was higher than that in patients with Irrigated-tip catheter (ITC) following TCC ablation failure (p = 0.02). The optimal cutoff value of the amplitude of the AP potential to guide the selection of a catheter for ablation was 1.07 mV, and the sensitivity and specificity were 80% and 90%, respectively. Conclusions The AP potential is helpful for the electrode selection in CS ablation.

Background : This study was conducted to compare the conventional retrograde arterial approach (RAA) with the transeptal approach (TSA) for radiofrequency catheter ablation (RFA) of left accessory pathways (AP). Materials and Methods: Sixty consecutive patients (44 male; mean age of 35.60 ± 11.63 years) with 60 left APs (39 overt and 21 concealed) underwent catheter ablation using the TS method (30 patients) and the RA method (30 patients) in an alternate fashion. The analysis was performed according to the intention-to-treat principle. Results : The transeptal puncture was successfully performed in 29 patients (96%). This access allowed primary success in the ablation in all the patients without any complication. When we compared this approach with the RAA there was no difference as regards the primary success (p = 0.103), fluoroscopy time (p = 0.565) and total time (p = 0.1917). Three patient in the RAA group presented a vascular complication. The TSA allowed shorter ablation times (p=0.006) and smaller number of radiofrequency applications (p = 0.042) as compared to the conventional RAA. The patients who had unsuccessful ablation in the first session in each approach underwent with the opposite technique (cross-over), with a final ablation success rate of 100%. Conclusion : The TS and RA approaches showed similar efficacy and safety for the ablation of left accessory pathways. The TSA allowed shorter ablation times and smaller number of radiofrequency applications. When the techniques were used in a complementary fashion, they increased the final efficacy of the ablation DOI: http://dx.doi.org/10.3329/cardio.v4i2.10458 Cardiovasc. j. 2012; 4(2): 139-147
