Current concepts for minimally invasive mitral valve repair

Area of Science:

• Cardiac Surgery
• Minimally Invasive Procedures
• Mitral Valve Repair

Background:

• Minimally invasive mitral valve repair involves several key procedural concepts.
• Recent discussions focus on aortic occlusion, Goretex-Neo-Chordae use, and the minithoracotomy approach for patients with prior cardiac surgery.
• Extensive experience from high-volume centers informs current recommendations.

Purpose of the Study:

• To review and discuss current concepts in minimally invasive mitral valve repair.
• To highlight the efficacy of Goretex-Neo-Chordae and specific myocardial protection strategies.
• To emphasize the importance of minimally invasive techniques in the context of emerging transcatheter options.

Main Methods:

• Review of 20 years of experience in minimally invasive mitral valve repair.
• Discussion of favored myocardial protection strategies: transthoracic aortic clamping with cardioplegia (primary) and hypothermic fibrillation (reoperative).
• Evaluation of the Goretex-Neo-Chordae technique for mitral valve regurgitation repair.

Main Results:

• The Goretex-Neo-Chordae concept is widely accepted and a preferred technique for many surgeons.
• Transthoracic aortic clamping with cardioplegia and hypothermic fibrillation are favored myocardial protection methods.
• Minimally invasive mitral valve repair demonstrates excellent outcomes.

Conclusions:

• Minimally invasive mitral valve repair, particularly with Goretex-Neo-Chordae, offers excellent results.
• Established minimally invasive techniques should be carefully considered alongside new transcatheter approaches.
• High-volume centers' experience provides valuable data for procedural recommendations.
