Study Details

Study Description

Brief Summary

The purpose of this study is to provide clinical data pertaining to the safety and performance of the Globe® Mapping and Ablation System for treating patients with atrial fibrillation.

Condition or Disease Intervention/Treatment Phase
  • Device: Global mapping and ablation device
N/A

Detailed Description

Upon successful enrolment, subjects will be scheduled for mapping and radiofrequency (RF) ablation. Cardiac CT imaging, echocardiography and baseline 12-lead ECG will be performed pre-procedure for screening and health assessment. During the procedure the Globe catheter will be delivered via standard femoral vein access and transseptal puncture. Anatomical and electrophysiological mapping of the left atrium (LA) will be followed by RF ablation to achieve pulmonary vein isolation (PVI). Additional lesions will be created as deemed appropriate by the investigator. Intracardiac electrogram mapping will be used to confirm PVI during the procedure. Echocardiography will be performed at discharge to assess cardiac function. Electrocardiograms by 12-lead ECG and 7-day Holter monitoring will be recorded at discharge, and 3, 6 and 12 months after treatment. Follow-up assessments will be performed at discharge, 7 days, and 1, 3, 6 and 12 months after treatment, to track freedom from documented AF and adverse events. Subject-reported AF symptomology and quality of life will also be assessed during follow-up.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Global mapping and ablation device

Device: Global mapping and ablation device
During the procedure the Globe catheter will be delivered via standard femoral vein access and transseptal puncture.
