Randomized Trial of Intracardiac Echocardiography During Cavotricuspid Isthmus Ablation

Abstract

ICE-guided ablation of the CTI significantly shortens the procedure and fluoroscopy time, markedly decreases radiation exposure, and time spent for ablation in comparison with fluoroscopy-only procedures. At the same time, visualization with ICE allowed successful ablation in challenging cases. (J Cardiovasc Electrophysiol, Vol. 23, pp. 996-1000, September 2012).

Novel Strategies in the Ablation of Typical Atrial Flutter: Role of Intracardiac Echocardiography

“…Regarding patients characteristics we found no significant differences between the two groups. Moreover, the complication and recurrence rates were identical in both groups [56]. We have shown that procedure and fluoroscopy time, the time spent for ablation were significantly shorter, radiation (dose-area product-DAP) and the sum of applied radiofrequency energy were significantly lower in the ICE-group (Table 1 ).…”

“…4 ) [56]. In our prospective, randomized study 102 patients were included [56]. Patients were randomized in two groups: fluoroscopy (n=52) or ICE guided (n=50) g…”

“…Our study has shown that ICE-guidance during isthmus ablation reduces overall procedure time, radiation exposure and decreases needless radiofrequency delivery [56]. “We concluded that ICE-guided ablation of the CTI is not indicated routinely but in selected patients when the conventional approach has failed additional ICE-guidance permits 100% procedural success and becomes justified” [56].…”

The influence of cavotricuspid isthmus length on total radiofrequency energy to cure right atrial flutter

“…Recently it has been shown that intracardiac echocardiography-guided ablation, which accurately shows the CTI anatomy, shortens the procedure and fluoroscopy time and is very helpful in challenging cases [8].…”

“…Recent studies and modern medical imaging techniques have provided important insights into the specific anatomy of the CTI, which is frequently dependent on the underlying cardiac disease [4][5][6][7][8]. Hence, these anatomical aspects affect the complexity and success rate of right AFl ablation.…”
