Summary
The Maze procedure effectively treated drug-resistant lone atrial fibrillation (AF) in 8 patients. 87.5% achieved normal sinus rhythm, with symptom improvement in all patients undergoing this AF treatment.
Area of Science:
- Cardiology
- Cardiac Surgery
Context:
- Lone atrial fibrillation (AF) and atrial flutter are common arrhythmias.
- Drug-resistant AF significantly impacts patient quality of life, causing symptoms like dyspnea, palpitations, and fatigue.
- The Maze procedure is an established surgical option for complex arrhythmias.
Purpose:
- To evaluate the efficacy of the Maze procedure for drug-resistant lone atrial fibrillation (AF) and atrial flutter.
- To assess symptom improvement and rhythm restoration post-Maze procedure in this patient cohort.
Summary:
- Eight patients with drug-resistant lone AF or flutter underwent the Maze procedure between 1992 and 1997.
- The patient group included those with sustained atrial fibrillation, paroxysmal atrial fibrillation, and sustained atrial flutter.
- Post-procedure, 7 out of 8 patients (87.5%) regained normal sinus rhythm. One patient with persistent paroxysmal AF experienced symptom improvement.
Impact:
- The Maze procedure demonstrates high success rates in restoring normal sinus rhythm for drug-resistant lone AF.
- Surgical intervention, like the Maze procedure, offers a viable treatment option for patients refractory to medical management.
- This study supports the Maze procedure as an effective therapeutic choice for debilitating lone AF.
