Atrial Fibrillation Clinical Trial
— MRICEMANOfficial title:
A Nationwide Multicenter Trial Assessing the Effects of Catheter Ablation on Burden of Atrial Fibrillation Recorded by Implantable Cardiac Monitor
The study will assess the atrial fibrillation burden recorded By implantable loop recorder at 12 and 24 months compared to baseline. The patients with clinical indication fo catheter ablation of paroxysmal atrial fibrillation will be randomized to three techniques: manual radiofrequency ablation, radiofrequency ablation using remote magnet monitoring, and cryoablation.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Free of atrial fibrillation | the proportion of patients remaining free from AF, atrial flutter (AFL) or atrial tachycardia (AT) (> 2 minutes) recorded by the implantable cardiac monitor (ICM, Reveal, Medtronic Co.) at 24 months. | 24 months | No |
Secondary | Total AF burden | total AF burden recorded by the implantable loop recorder during the 24 month follow-up. | 24 months | No |
Secondary | Incidence of adverse events | Safety is one of the secondary endpoints. The following potential adverse events will be monitored: Any previous left atrial ablation or surgery Any cardiac surgery or percutaneous coronary intervention within three months prior to enrolment. Secondary AF Stroke or transient ischemic attack within six months prior to enrolment Myocardial infarction within three months prior to enrolment Left ventricular ejection fraction < 40 % Anteroposterior left atrial diameter >55 mm by transthoracic or transesophageal echocardiography Implanted prosthetic valve |
24 months | Yes |
