Conclusions: Advisor HD Grid HD mapping catheter not only allows rapid assessment of voltage and activation but more importantly the directionality of conduction to facilitate the identification of the isthmus in complex scar‐related AT.

Conclusion: The HD grid catheter is a high density mapping catheter able to reliably collect high density of voltage points rapidly to achieve and confirm effective PVI.

Pulmonary Vein Reconnection Mapping with Advisor HD Grid Demonstrating Local EGM which Were Not Visible on TactiCath Ablation Catheter.

Case Discussion: Being able to display only the highest amplitude signals from orthogonal recordings, HD grid may be able to detect local EGM signals which previously would have been missed and thus may offer more effective therapeutics.

Conclusion: High-resolution mapping of the atria can be performed rapidly and accurately using the HD Grid for the catheter ablation of AF, redo AF ablations, and post-PVI ATs. As well as providing rapid voltage and propagation maps, this catheter can be positioned in such a way as to rapidly localize gaps and provide information on the direction of conduction. In particular, omnipolar mapping will allow for accurate directionality as well as more detailed substrate mapping in the presence of changes in the direction of conduction. This will enhance the accuracy of mapping in atrial arrhythmias. Further algorithms are being studied in order to rapidly automate conduction directionality in focal and reentry circuits.
