Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Aim of the project is to assess the long-time clinical impact of surgical ablation (MAZE procedure) on patients who suffer from atrial fibrillation but are indicated to a cardiac surgery for other predominant cardiac diagnosis (heart valve surgery, coronary revascularization or combined surgery). In recent years, those patients are more and more frequently indicated to some type of MAZE procedure, without the real benefit of this procedure for patients has been assessed with an enough large, randomized study. Even though it is well known, that MAZE procedures declines the early postoperative incidence of atrial fibrillation, convincing data about its mid-term and long-term impact on patients and about the appearance of recidives of atrial fibrillation in long-time horizon are still missing. Our hypothesis assumes, that MAZE procedure will significantly decrease the appearance of atrial fibrillation one year after the operation, without increasing mortality or incidence of serious postoperative complications in thirty postoperative days.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A = MAZE

Patients indicated to a cardiac surgery (bypass, valve repair or combinated surgery)with documented atrial fibrillation in 6 preoperative months undergo the operation together with MAZE procedure

Cox-MAZE III

Intervention Type PROCEDURE

Maze procedure according to standards of the department

B = non-MAZE

Patients indicated to a cardiac surgery (bypass, valve repair or combinated surgery)with documented atrial fibrillation in 6 preoperative months undergo the operation (without MAZE procedure).

No interventions assigned to this group
