A Computational Framework to Benchmark Basket Catheter Guided Ablation

Abstract: Atrial fibrillation (AF) ablation guided by basket catheter mapping has shown to be beneficial. Yet, the initial excitement is mitigated by a growing skepticism due to the difficulty in verifying the protocol in multicenter studies. Overall, the underlying assumptions of rotor ablation require further verification. The aim of this study was therefore to test such hypotheses by using computational modeling. The 3D left atrial geometry of an AF patient was segmented from a pre-operative MR scan. Atrial activatio… Show more

“…In the last decades, several works have analyzed atrial EGMs acquisition by different catheters using a simulation approach ( Alessandrini et al, 2017 ; Roney et al, 2017b ; Martinez-Mateu et al, 2018 , 2019 ; Hwang et al, 2019 ; Ravikumar et al, 2021 ), or have developed methods for rotor tracking with simulated and/or experimental EGMs ( Roney et al, 2014 ; Ugarte et al, 2015 ; Valinoti et al, 2015 , 2017 ; Ganesan et al, 2019a , b ).…”

“…We tested this approach using an anatomically personalized model of a human AF patient. This study builds on our previous work (Alessandrini et al, 2017 ), which is extended in several ways: the sensitivity of the rotor trajectory estimated from catheter signals to the distance between the catheter and the atrial wall is studied; simulated acquisitions of a realistic Constellation basket catheter are considered in addition to simple 2D grid catheters; the basket-guided FIRM ablation protocol is simulated including the treatment by implementing up to three successive ablations.…”
