Summary
This study presents a surgical technique for mitral valve repair that restores good valve function and normal heart rhythm. The procedure addresses rheumatic mitral valve disease and chronic atrial fibrillation, improving patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Cardiac Arrhythmias
- Valvular Heart Disease
Background:
- Mitral valve surgery aims for optimal valve function and sinus rhythm restoration.
- The left atrium and mitral valve are considered a functional anatomic unit.
- Chronic atrial fibrillation often accompanies mitral valve disease.
Purpose of the Study:
- To describe a surgical technique combining mitral valve repair with left atrial procedures.
- To evaluate the efficacy of this combined approach in patients with rheumatic mitral valve disease and atrial fibrillation.
Main Methods:
- Surgical technique involves left atrial size reduction, pulmonary vein isolation, and left atrial appendage amputation.
- Mitral valve repair is performed concurrently.
- Procedure applied to 4 patients with rheumatic mitral valve disease and chronic atrial fibrillation.
Main Results:
- Successful restoration of good mitral valve function in all patients.
- Restoration and maintenance of sinus rhythm observed in all patients.
- Positive outcomes assessed at 16 to 20 months post-surgery.
Conclusions:
- The described surgical technique is effective for mitral valve repair in patients with rheumatic disease and atrial fibrillation.
- Simultaneous left atrial procedures contribute to restoring sinus rhythm.
- This integrated approach offers a promising solution for complex mitral valve disease.
