mitral valve repair
Surgical correction of mitral valve dysfunction while preserving the patient's native valve tissue and apparatus.
Full Definition
Mitral valve repair is a surgical technique that corrects mitral valve pathology while maintaining the patient's own valve tissue and subvalvular apparatus. This approach is preferred over valve replacement when technically feasible because it preserves the natural valve mechanics, maintains left ventricular function, and avoids the need for long-term anticoagulation. Repair techniques include leaflet resection, chordal replacement, annuloplasty ring insertion, and edge-to-edge repair. The procedure requires detailed understanding of mitral valve anatomy and pathophysiology to achieve durable results with low recurrence rates.
Usage
Usage note: Distinguish clearly from mitral valve replacement in clinical documentation.
