HeartRhythm Case Reports High Resolution mapping of the atria using the High Definition Grid Catheter Kathryn Lauren Hong, BSc, Damien Redfearn, MD MB BCh BAO MRCP, Sanoj Chacko, PhD MB BCh BAO MRCP, Jason Baley, MSc, Adrian Baranchuk, MD, Benedict Martin Glover, MD MB BCh BAO MRCP FHRS FESC HeartRhythm Case Reports DOI: 10.1016/j.hrcr.2018.12.012 Copyright © 2019 Terms and Conditions

Figure 1 Voltage map of the left atrium showing positioning of the HD Grid at the lower Coumadin ridge between the left a. trial appendage (LAA) and the left superior pulmonary vein (LSPV) and left inferior pulmonary vein (LIPV). Electrograms selected from the catheter show signals propagate from the LAA to the pulmonary veins demonstrating that the signals recorded originate from the LAA HeartRhythm Case Reports DOI: (10.1016/j.hrcr.2018.12.012) Copyright © 2019 Terms and Conditions

Figure 2 Voltage mapping of the left atrium using the HD Grid with evidence of electrical conduction through the right posterior carina connecting into the right superior pulmonary vein (RSPV). Local electrograms recorded from this region showed significant fractionation (total duration of fractionation 132msec) in this region suggestive of slow conduction from the LA to the RSPV. Pacing from the right inferior pulmonary vein (RIPV) from the distal electrodes (A1-A2) demonstrated evidence of local capture within the PV on poles B1-B2, C1-C2, D1-D2, C2-C3, D2-D3 which did not result in local LA depolarization on poles A3-A4) HeartRhythm Case Reports DOI: (10.1016/j.hrcr.2018.12.012) Copyright © 2019 Terms and Conditions

Figure 3 Voltage mapping of the left atrium in a patient with a post PVI AT showing two regions of reconnection along the posterior region of the RSPV and RIPV. Entrainment confirmed involvement of these regions during tachycardia. Local electrograms recorded from the distal electrodes on the HD Grid at the superior region of reconnection revealed 2:1 mid diastolic potential’s which indicated slow conduction through a critical isthmus HeartRhythm Case Reports DOI: (10.1016/j.hrcr.2018.12.012) Copyright © 2019 Terms and Conditions
