Outcomes

Primary Outcomes

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 Outcomes

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
