Insights
The Cox/Maze III operation effectively treats chronic atrial fibrillation during cardiac surgery, with 93% of patients achieving sinus rhythm post-procedure without increased risks.
Area of Science:
- Cardiovascular Surgery
- Cardiac Electrophysiology
Context:
- Chronic atrial fibrillation often requires surgical intervention.
- Mitral valve surgery presents an opportunity for concurrent atrial fibrillation treatment.
Purpose:
- To evaluate the efficacy and safety of the Cox/Maze III operation for chronic atrial fibrillation during other cardiac procedures.
Summary:
- This study analyzed 14 patients undergoing the Cox/Maze III procedure alongside mitral valve surgery, atrial defect closure, or left atrial thrombectomy.
- Mean preoperative atrial fibrillation duration was 5.1 years.
- At a mean follow-up of 13.1 months, 93% of patients maintained sinus rhythm.
Impact:
- The Cox/Maze III operation is a safe and effective surgical strategy for managing chronic atrial fibrillation.
- This approach can be integrated into other cardiac surgeries without elevating risks.
Unlabelled:
We examined the results of simultaneous surgical treatment of chronic atrial fibrillation using a Cox/Maze III operation during mitral valve surgery (n = 12), atrial secundum defect closure (n = 1), combined operation (mitral valve and atrial secundum; n = 1) and thrombectomy from the left atrium (n = 1). Mean preoperative atrial fibrillation was 5.1 years (range 0.5-12 years). In the mean follow-up period of 13.1 months (1-24 months), 14 patients (93%) had sinus rhythm.
Conclusion:
(1) The surgical treatment of chronic atrial fibrillation using a Cox/Maze III operation can be performed without increased perioperative or postoperative risks; (2) Cox/Maze III operation represents an effective surgical treatment of chronic atrial fibrillation.
