VIVO is a per-procedural planning tool designed to non-invasively identify the origin of a ventricular arrhythmia.

The primary effectiveness objective is to assess the types of procedures where VIVO is used to plan and/or guide the ablation procedure or to determine a diagnosis of arrhythmia.

Primary Effectiveness endpoint: Summarize the types of procedures where VIVO was utilized in the procedure to include the number of VT vs PVC, whether VIVO improved procedural planning and acute procedural success measured as termination or reduction in arrhythmia.

Primary safety objective is to assess any adverse events related to the device and procedure.

Primary Safety endpoint: Summarize the number of adverse events related to VIVO or procedure.

Secondary effectiveness objective is to evaluate the success of the ablation procedure (if performed) at follow- up visits (3, 6 and 12 months).

Secondary effectiveness endpoint: Summarize the success of the ablation procedure at each follow up visit.
