TABLE 1. There Were 10 Patients Enrolled in the Observational Study With an Average Age of 13±4.5 Years, Weight of 55.5±27.8 kg, Height of 154.2±24 cm, and Body Surface Area of 1.5±0.5 m2 With 60% of Participants Being Female. Electrophysiology Substrates Included 3 Patients With Atrioventricular Nodal Reentrant Tachycardia (AVNRT) and 7 Patients With Accessory Pathway (AP) Mediated Tachycardias (6 Manifest, 1 Concealed). Of the 7 Patients With AP Mediated Tachycardias, There Were 6 Left Sided APs (1 Concealed, 5 Manifest) and 1 Right Sided AP (Manifest). All 10 Patients had Geometry Creation of the Right Atrium and Coronary Sinus. Six (60%) had Left Atrial Geometries Created in Addition to the Right Sided Structures. Local Activation Timing (LAT) Maps Were Created in 7 Patients (7 Patients With AVRT), and Voltage Maps Were Created in 5 Patients (3 Patients With AVNRT and 2 Additional Patients With AVRT). On Qualitative Assessment Between the LAT and Voltage Maps Generated in the EAMS as Compared to ĒLVIS, the Maps Were Equivalent With Regards to Differentiability of Color Texture. There Have Been No Acute or Chronic Adverse Events and No Clinical Recurrences of Tachycardia.
