Summary
Predictors of early atrial fibrillation (AF) recurrence after maze and valvular surgery were identified. Older age, multivalvular surgery, and persistent AF increased risk, while CABG and beta-blockers showed protective effects.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- The concomitant Maze procedure is effective for atrial fibrillation (AF) in patients undergoing mitral valve surgery.
- Early recurrence of AF post-procedure necessitates identifying predictive factors.
Purpose of the Study:
- To define predictors of early AF recurrence following a concomitant Maze procedure combined with valvular surgery.
- To develop a model for anticipating early AF recurrence based on patient characteristics.
Main Methods:
- Retrospective analysis of 234 patients with AF who underwent concomitant valvular replacement and Maze procedure.
- Patients were categorized into sinus rhythm and AF groups post-operatively for comparison.
Main Results:
- 148 out of 234 patients maintained sinus rhythm.
- Independent predictors of in-hospital AF recurrence included age, number of replaced valves, concomitant coronary artery bypass grafting (CABG), preoperative persistent AF, and beta-blocker therapy.
Conclusions:
- Older age, multivalvular surgery, and persistent preoperative AF predict higher risk of early recurrent AF.
- Concomitant CABG and beta-blocker therapy demonstrated a protective effect.
- A predictive model using preoperative and operative factors can assess patient benefit from combined procedures.
