Summary
The Maze procedure, especially when combined with other cardiac surgeries, effectively treats atrial fibrillation. This surgical technique offers a high cure rate with no operative mortality, making it a preferred option.
Area of Science:
- Cardiovascular Surgery
- Electrophysiology
Background:
- Atrial fibrillation is a common arrhythmia often requiring intervention.
- Noncurative therapies have limitations for symptomatic atrial fibrillation.
- The Maze procedure is an established surgical treatment for atrial fibrillation.
Purpose of the Study:
- To evaluate the efficacy and safety of the Maze procedure, particularly when combined with other cardiac surgeries.
- To assess the outcomes of the unmodified "cut-and-sew" Maze-III technique.
Main Methods:
- Retrospective review of 99 Maze procedures performed since 1993.
- Analysis of combined procedures, including concomitant valve surgery.
- Application of the "cut-and-sew" Maze-III technique in all cases.
Main Results:
- 78 of 99 procedures (79%) were combined operations.
- 88% of combined procedures involved valve surgery.
- 97% cure rate for atrial fibrillation.
- No operative mortality.
- Median postoperative stay of 7 days.
- 6% required pacemaker implantation for sick sinus syndrome.
Conclusions:
- The Maze procedure is highly effective for symptomatic atrial fibrillation, particularly in patients undergoing combined cardiac surgery.
- The original Maze-III "cut-and-sew" technique demonstrates excellent outcomes and should be considered the procedure of choice.
- Broader adoption of the Maze procedure is recommended for eligible patients.
