Role of Subsequent Atrial Tachycardia in Mechanisms of Persistent AF

Johannes Gutenberg University (JGU)

Status: Completed

Conditions: Atrial Fibrillation

Treatments: Procedure: Catheter ablation of subsequent atrial tachycardia

Study type: Observational

Identifiers

Details and patient eligibility

About

In this study, the investigators aim to examine the prognostic role of subsequent Atrial Tachycardias (ATs) in the mechanisms of atrial fibrillation (AF). Therefore, the investigators compare patients who were randomly assigned to either undergo cardioversion after AF has been terminated to AT or further ablation until the achievement of sinus rhythm.

Enrollment: 110 patients

Sex: All

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• persistent AF for at least 1 months,
• age > 18 years,
• refractory to drug therapy,
• no prior ablation

Exclusion criteria

• prior AF ablation

Trial design

110 participants in 2 patient groups

Group A: cardioversion at AT

Description:

after achievement of AT, pts were cardioverted

Group B: ablation to SR

Description:

After AT has been achieved, all subsequent AT were ablated with the endpoint of procedural SR termination

Treatment:

Procedure: Catheter ablation of subsequent atrial tachycardia
