Summary
This study modified the Paneth-Burr semicircular suture annuloplasty for mitral regurgitation (MR). The modified procedure improved MR in most patients, particularly when the annulus size was reduced.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Medical Devices
Context:
- Mitral regurgitation (MR) repair traditionally involves leaflet plication or chordae reconstruction with annuloplasty.
- Previous methods like the JH Kay technique showed limitations in long-term results for diverse mitral lesions.
- The Paneth-Burr semicircular suture annuloplasty has been adopted as a primary approach for MR since 1991.
Purpose:
- To demonstrate a modified operative procedure of the Paneth-Burr semicircular suture annuloplasty for mitral regurgitation.
- To evaluate the changes in annular size and MR severity post-surgery using Doppler echocardiography.
- To determine the optimal annular size after annuloplasty for improved MR outcomes.
Summary:
- A modified Paneth-Burr annuloplasty using double EPTFE sutures with pledgets was performed on 21 MR patients.
- Patients were grouped based on post-annuloplasty annular diameter: Group A (<90% normal, 15 pts) and Group B (>90% normal, 6 pts).
- Group A showed significant improvement in MR from grade 2-4 to 0-1 in 14 out of 15 patients.
Impact:
- The modified Paneth-Burr method demonstrates effectiveness in reducing mitral regurgitation.
- Doppler echocardiography is a valuable tool for assessing annular size and MR severity post-repair.
- Achieving an optimal, smaller annular diameter appears crucial for successful MR reduction.
