Endocardial Mapping With the CoreMap EP Mapping System

Overview

This is a global, multi-site, prospective, feasibility study.

Description

The INvENI Study consists of two phases. For Phase 1, the goal is to collect and analyze high fidelity endocardial electrograms (EGMs) in patients with persistent and long-standing persistent AF. For Phase 2, the goal is the initial development and evaluation of a CoreMap-guided tailored ablation strategy and to demonstrate safety and chronic efficacy of the CoreMap EP Mapping System.

Eligibility
