SOLAR & ATRILAZE Atrial Fibrillation Trial
- Conditions
- Atrial Fibrillation
- Interventions
- Device: Laser MAZE by Ablation of Cardiac Tissue
- Registration Number
- NCT00734058
- Lead Sponsor
- EndoPhotonix, Inc.
- Brief Summary
The purpose of study is to conduct a pivotal evaluation of the EndoPhotonix™ SOLAR™ System and ATRILAZE™ System in order to obtain a labeling claim on the devices for the treatment of atrial fibrillation.
The study will test the safety and effectiveness of the EndoPhotonix™ Laser Ablation Systems to photocoagulate cardiac tissue during cardiac surgery, to create electrical isolation of the pulmonary veins and create other electrical isolation lesions in order to treat atrial fibrillation. The surgical procedure will be conducted during concomitant mitral valve repair or replacement surgery or in combination with other cardiac surgery including aortic valve surgery, tricuspid valve surgery, or coronary artery bypass surgery.
- Detailed Description
The study objective is to generate Level II controlled data to support the expansion of indications for the SOLAR™ System based on 0-30 day data; as well as to support the expansion of indications for the SOLAR™ System and ATRILAZE™ System for the treatment of atrial fibrillation based on 180 days data. The data will be evaluated by comparing post-operative data to the historical control data. The subjects in the study cohort will receive laser ablation therapy using the investigational device during a concomitant surgical procedure.

- Primary Outcome Measures
Name Time Method Acute SAE: Death, mediastinitis, myocardial infarction, stroke, transient ischemic attack (TIA), pulmonary embolism, peripheral arterial embolism, esophageal injury, pulmonary vein stenosis; phrenic nerve damage 0 through 30 days or length of stay Freedom from atrial fibrillation by 24-hour 3-lead Holter Monitor at the 180 day evaluation. On or Off Class 1 and III anti-arrhythmic medication 180 days
- Secondary Outcome Measures
Name Time Method Determine binary freedom from AF, independent of anti-arrhythmic status as documented by 24 hour 3-Lead Holter Monitor. Reduction of AF burden with assumption of 100% initial burden. To establish improvement in Quality of Life. 180 days SAE: Death, mediastinitis, myocardial infarction, stroke, transient ischemic attack (TIA), pulmonary embolism, peripheral arterial embolism, esophageal injury, pulmonary vein stenosis; phrenic nerve damage 180 days
