Further study details as provided by AtriCure, Inc.:

Primary Outcome Measures:
  • Primary efficacy endpoint is the proportion of treated patients who are free of atrial fibrillation without the need for anti-arrhythmic agents at the six-month follow-up visit. [ Time Frame: 6 months ]
  • The primary safety endpoint is the occurrence of serious adverse events that are considered to be associated with the Maze procedure. [ Time Frame: 30 days ]

Secondary Outcome Measures:
  • The secondary efficacy endpoint is the proportion of patients in the treatment group who are free of atrial fibrillation independent of the need for anti-arrhythmic drugs. [ Time Frame: 6 Months ]
  • The secondary safety endpoints are: total cross clamp time, total time on bypass, length of hospital stay (days), and length of ICU stay (hours) [ Time Frame: Discharge ]

Enrollment: 39
