Pulmonary Vein Ablation of Atrial Fibrillation Using Magnetic Navigation: Single Ring Versus Circumferential Techniques

University Medical Center Goettingen

Status: Completed

Conditions: Pulmonary Vein Isolation, Ablation Time, Procedure Time, Freedom Form Atrial Fibrillation

Treatments: Procedure: Circumferential pulmonary vein ablation; Procedure: single ring pulmonary vein ablation

Study type: Interventional

Funder types: Other; Industry

Identifiers

NCT01583075

STXS 10-005

Details and patient eligibility

About

The single-ring ablation method aims for isolation of the posterior LA wall including the pulmonary veins. If avoiding ablation on the posterior LA wall esophageal injury is unlikely.

Aim of this prospective study was to evaluate the safety and efficacy of an RMN-guided single-ring ablation method as compared to standard RMN-guided circumferential PVA.
