Summary

Mitral valve repair offers advantages over replacement, including reduced risks of blood clots, hemolysis, and infection. This approach improves long-term survival, especially in elderly patients with degenerative mitral valve disease.

Area of Science:

Cardiovascular Surgery
Valvular Heart Disease

Background:

The causes of mitral valve disease are shifting, with degenerative conditions becoming more prevalent in aging populations.
Rheumatic heart disease is declining as a primary cause of mitral valve issues.

Purpose of the Study:

To review surgical techniques for mitral valve repair.
To discuss the advantages of mitral valve repair over replacement.
To explore future trends in mitral valve surgery.

Main Methods:

Literature review of current surgical techniques for mitral valve repair.
Analysis of comparative outcomes between mitral valve repair and replacement.

Main Results:

Mitral valve repair is associated with lower rates of thromboembolism, hemolysis, and infectious endocarditis compared to replacement.
For patients in sinus rhythm, repair eliminates the need for anticoagulation due to rare thromboembolic events.
Improved long-term survival rates are observed in patients undergoing mitral valve repair.

Conclusions:

Mitral valve repair is a favorable option, offering significant benefits over replacement.
The shift towards degenerative etiologies supports the increased use of mitral valve repair.
Future trends likely involve further advancements in mitral valve repair techniques.
