The primary objective of this study is the identification of LA and LAA areas driving atrial fibrillation to study their relationship with LAA-LA connections and sinus rhythm (SR) analysis using the CartoFinder and COHERENT algorithms that CARTO V7 offers.~The CartoFinder tool will be able to determine the activation patterns of reentrant drivers (rotors) in the LA and LAA in AF. The characterization of areas harboring rotors could be performed with the COHERENT tool provided by CARTO V7 to determine the activation patterns during reentrant rhythms, and after sinus rhythm restoration it could be used to assess the conduction patterns at LA-LAA connections and driver sites identified with CartoFinder.
The primary objective of this study is twofold, first we aim to identify rotors in atrial fibrillation (AF) and analyze their relationship with the left atrium-left atrial appendage (LA-LAA) connections. Secondly, we will analyze the areas harboring rotors in SR to define the characteristics that describe the presence of rotors.
