[Mitral valve repair for infectious endocarditis]
1Department of Thoracic and Cardiovascular Surgery, Kobe General Hospital.
Abstract:
Fourteen patients with mitral regurgitation resulting from infectious endocarditis underwent mitral valve repair between December 1988 and July 1994. There were nine males and five females aged from 14 to 70 years (mean 40.2 +/- 19.7 years). Three patients had active endocarditis. Time between the onset of endocarditis symptoms and surgery ranged from 1 to 24 months (mean 8.3 months). Bacterial findings were Streptococcus in eight patients, Staphylococcus in one, and unknown in five. All macroscopically infected tissue was excised in patients with active endocarditis. Carpentier's reconstructive techniques were mainly used. There were no hospital deaths. Mean follow-up was 29 months and complete. Thirteen patients were in New York Heart Association functional class I and one in class II. There were no late deaths, reoperations, recurrent endocarditis, thromboembolic events, or other valve-related morbidity. We conclude that mitral valve repair is an attractive procedure in patients with mitral regurgitation resulting from infectious endocarditis.
Insights
Mitral valve repair is a safe and effective treatment for mitral regurgitation caused by infectious endocarditis. This study found no deaths or major complications in patients undergoing this procedure.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Cardiac Valve Disease
Context:
- Infectious endocarditis frequently leads to mitral regurgitation.
- Surgical intervention is often necessary for valve repair or replacement.
- Limited data exists on the long-term outcomes of mitral valve repair specifically for endocarditis-related regurgitation.
Purpose:
- To evaluate the efficacy and safety of mitral valve repair in patients with mitral regurgitation secondary to infectious endocarditis.
- To assess short-term and long-term clinical outcomes, including mortality, morbidity, and functional status.
Summary:
- Fourteen patients with endocarditis-related mitral regurgitation underwent mitral valve repair using Carpentier's techniques.
- No hospital deaths occurred. Mean follow-up was 29 months with no late deaths, reoperations, or valve-related complications.
- Thirteen patients improved to New York Heart Association functional class I, and one to class II.
Impact:
- Mitral valve repair is a viable and attractive option for managing mitral regurgitation in infectious endocarditis.
- The findings support the use of reconstructive valve surgery to improve patient outcomes and quality of life.
- This study contributes evidence supporting valve-sparing procedures in complex cardiac conditions.
