Summary
Mitral valve repair is increasingly preferred over replacement due to reduced mortality and morbidity. Advanced techniques now enable repair in up to 95% of mitral regurgitation patients, improving long-term outcomes.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Disease
- Medical Technology
Context:
- Degenerative mitral regurgitation (MR) is now the leading cause in Japan, surpassing rheumatic heart disease.
- Mitral valve repair offers improved outcomes compared to valve replacement.
- Surgical indications for MR are expanding to include asymptomatic patients with early signs of cardiac dysfunction.
Purpose:
- To highlight the growing prevalence and efficacy of mitral valve repair techniques.
- To discuss the shift in etiology of MR towards degenerative causes.
- To outline evolving criteria for surgical intervention in MR.
Summary:
- Mitral valve repair is becoming more common, offering better results than valve replacement.
- Degenerative MR is the primary indication for repair, with techniques like artificial chordal implantation achieving success in 95% of cases.
- Surgery is now considered for asymptomatic MR patients showing early signs of left ventricular dysfunction or arrhythmias.
Impact:
- Increased adoption of mitral valve repair techniques.
- Improved long-term prognosis for patients with mitral regurgitation.
- Refined surgical decision-making for MR, including asymptomatic individuals.
