Does high-resolution mapping using the HD Grid catheter facilitate the assessment of conduction directionality and signal differentiation during atrial fibrillation ablation?
The HD Grid catheter allows for rapid, high-resolution mapping of the atria, facilitating the differentiation of near-field and far-field signals and the assessment of conduction block during AF ablation.
Hong et al. (2019) conducted a case report in Atrial fibrillation and atrial tachycardia (n=3). HD Grid catheter mapping was evaluated on Feasibility of high-resolution mapping and differentiation of far-field and near-field signals. High-resolution mapping using the HD Grid catheter successfully differentiated near-field from far-field signals, assessed conduction directionality, and identified gaps in prior ablation lines.
