Summary
The maze procedure effectively treats atrial fibrillation, restoring normal heart rhythm in 98% of patients. This surgical intervention offers a curative solution for many with drug-resistant symptomatic atrial fibrillation.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Atrial fibrillation is a common arrhythmia impacting cardiac function.
- Medically refractory symptomatic atrial fibrillation presents significant treatment challenges.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the maze procedure for treating atrial fibrillation.
- To determine the long-term success rate of the maze procedure in restoring normal sinus rhythm.
Main Methods:
- The maze procedure was performed on 75 patients between 1987 and 1992.
- Follow-up data was collected for 65 patients for at least 3 months post-operation.
Main Results:
- The maze procedure achieved a 98% success rate in curing atrial fibrillation and restoring atrioventricular synchrony.
- 89% of patients were free from atrial fibrillation without medication, with an additional 9% requiring medication for control.
- A single perioperative death (1.3%) occurred in a patient undergoing a combined procedure.
Conclusions:
- The maze procedure is a highly effective treatment for medically refractory symptomatic atrial fibrillation.
- It offers a curative option with a high success rate and favorable long-term outcomes.
