BoxX-NoAF Clinical Trial

Sponsored by AtriCure, Inc.

About this study

Post Operative Atrial Fibrillation (POAF) is the most common complication of cardiac surgery. POAF incidence can exceed 50% depending on the patient baseline characteristics and surgery type. Patients with POAF tend to have worse acute and long-term clinical outcomes. BoxX-NoAF is a randomized trial to evaluate if prophylactic ablation and exclusion of the Left Atrial Appendage at the time of other routine cardiac surgery can reduce the incidence of post operative AF and clinical AF during long term follow up in patients who have not yet developed AF but are at risk.

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
