Study Summary

This study will evaluate the use of a robotic device that is remotely controlled to maneuver a circular mapping catheter in the left atrium during Atrial Fibrillation (AF) ablation procedures.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Left atrial AF ablation procedure requiring the use of a Lasso mapping catheter

  • Subject must be at least 18 years of age

  • Subject must be male, female of no childbearing potential, or a female that has anegative pregnancy test prior to randomization

Exclusion

Exclusion Criteria:

  • Unable to safely expose subject to a magnetic field

  • Prior AF ablation procedure

  • Patients with fewer than 4 PVs are excluded

  • Patients with persistent AF in whom early recurrence of AF following cardioversionwould preclude completion of the pacing maneuvers described in the protocol orpatients with other conditions that would similarly preclude completion of the pacingmaneuvers

  • Contraindication to procedure or unable to return for follow-up

  • History of clotting disorder, bleeding abnormalities or contraindication toanticoagulation

  • Actively participating in other cardiac device trial(s)

  • Currently pregnant

  • Under 18 years of age

  • Prosthetic valves

  • Atrial abnormalities (thrombus, myxoma or baffle)

  • Other exclusions per the investigator

Study Description

Key to the success of an electrophysiology procedure is the ability to accurately map, sense and pace the heart. Electrophysiology mapping catheters are available in a variety of shapes and electrode configurations. The majority of these catheters are manipulated manually by the physician. The Vdrive simplifies these manipulations by allowing an operator to mechanically advance, retract, rotate, deflect and maneuver a circular mapping catheter. The circular mapping catheter is not altered in structure, function or indication in the same manner as the predicate device (Cardiodrive Catheter Advancement System).

This is a prospective, randomized, non-blinded, controlled study comparing manual navigation of a circular mapping catheter with mechanical navigation by the Vdrive. A total of 120 patients are expected to complete the study: 80 patients in the Vdrive navigation arm and 40 patients in the manual navigation arm. Patients will be enrolled at a minimum of one site in the European Union where the product is currently marketed and the United States, where the Vdrive is considered to be investigational.
