Summary
Bileaflet preserving mitral valve replacement (MVR) improves left ventricular function and reduces complications. This technique enhances left ventricle ejection fraction (LVEF) and eliminates left ventricle outflow tract (LVOT) obstruction risk.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Minimally Invasive Cardiac Surgery
Background:
- Bileaflet preserving mitral valve replacement (MVR) is gaining traction due to satisfactory outcomes.
- Modifications are crucial to prevent prosthetic valve dysfunction and left ventricle outflow tract (LVOT) obstruction.
Purpose of the Study:
- To evaluate the efficacy of bileaflet preserving MVR compared to conventional MVR.
- To assess the impact on left ventricular performance and postoperative outcomes.
Main Methods:
- A comparative study involving 51 patients in the conventional MVR group and 43 in the bileaflet preserving MVR group.
- Detailed description of the surgical technique for preserving mitral valve leaflets during MVR.
Main Results:
- Bileaflet preserving MVR showed significantly longer cross-clamping and bypass times.
- Postoperative left ventricle ejection fraction (LVEF) increased significantly in the bileaflet preserving group, while it decreased in the conventional group.
- Reduced inotropy requirement in the bileaflet preserving MVR group.
Conclusions:
- Bileaflet preserving MVR improves left ventricular performance at rest and during exercise.
- This technique reduces mortality and morbidity post-MVR.
- The described method effectively eliminates the risk of LVOT obstruction.
