ABSTRACT
BACKGROUND:
Although fluoroless transseptal puncture (TSP) guided by intracardiac echocardiography (ICE) has been used for many years, there are no reports of an accurate site-specific method for TSP in detail, especially about the safety and efficiency of the method. This study aimed to compare the efficacy and safety of TSP guided by three-dimensional ICE using a fluoroless site-specific method with that of the conventional fluoroless method in patients with atrial fibrillation (AF).METHODS:
This prospective study included 60 patients with AF scheduled for radiofrequency ablation who were assigned to undergo modified fluoroless site-specific TSP (SS-ICE group, n = 30) or conventional fluoroless TSP (C-ICE group, n = 30). TSP was guided by three-dimensional ICE in both study groups.RESULTS:
All fluoroless TSP were performed successfully in both groups. There were no significant differences in patient characteristics, Pre-TSP time (11.3 ± 1.7 min vs. 11.1 ± 1.6 min, P = 0.822) and TSP time (3.4 ± 0.9 min vs. 3.5 ± 1.1 min, P = 0.772) between the SS-ICE group and the C-ICE group. The distance between the actual traversing point and the presetting point in the fossa ovalis was less than 5 mm in 87% of patients (26/30, 3.1 ± 1.2 mm) in the SS-ICE group. There were no TSP-related complications in either group.CONCLUSION:
SS-ICE method is a simple, safe, and effective approach for fluoroless site-specific TSP.Palavras-chave
