Summary

This is a single centre study enrolling 15 subjects with structurally normal hearts that are already indicated for a ventricular ablation procedure (VT or PVCs). The purpose is to compare the accuracy of VIVO and to assess its efficacy to decrease procedural time, and ideally, the procedural overall costs, as compared to standard of care ablation procedures. Results will be compared with data from

Detailed description

VIVO TM is a non invasive mapping system which can be used to localize PVC / VT origin prior to the ablative procedure. Subjects scheduled for catheter ablation with VIVO will undergo a CT scan prior to the procedure, which will be used to create a personalized 3D model. This will be merged with a 3D photograph (taken at the start of the procedure) of the ECG electrodes on the subject's torso. Then, the recording of the 12 lead ECG will be imported into the VIVO software. All of this data will be combined via the software and a mathematical algorithm will determine the origin of the arrhythmia. This will show the physician where to perform a successful ablation. After 3 months, the subject will return for follow up and will receive another ECG Holter monitor (ECG recording) to determine ablation success. Subjects will be exited from the study after the 3 month follow up visit. Patients will receive standard clinical care prior to, during and after their scheduled procedure, as well as after being discarded from the trial. Results will be analysed and compared to those from an historical cohort of patients (age / gender matched, undergone the same procedure) ablated by the same operator within the previous 5 years (from a database already collected). Data will be anonymised as per current regulations.
