The novel automated algorithm Cartosoundfam is a model\u2010based algorithm which reconstructs a 3D anatomy of the left atrium (LA) based on a set of 2D intracardiac echocardiography (ICE) frames, without the need to manually annotate ultrasound (US) contours.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>The aim of this study was to determine the feasibility of the Cartosoundfam module in routine clinical setting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We included 16\u00a0patients\u00a0undergoing LA mapping\/catheter ablation.
