Techniques for ensuring the correct length of new mitral chords

Area of Science:

• Cardiovascular Surgery
• Cardiac Valve Repair
• Mitral Valve Disease

Background:

• Degenerative mitral insufficiency repair is superior to valve replacement.
• Posterior mitral leaflet prolapse is common and treated with resection and annuloplasty.
• Anterior mitral leaflet prolapse repair techniques are less established.

Purpose of the Study:

• To describe simple, safe, and reproducible surgical maneuvers for mitral valve chord replacement.
• To address the challenges of anterior mitral leaflet prolapse repair.
• To enhance the durability and success of mitral valve repair using expanded polytetrafluoroethylene (PTFE) sutures.

Main Methods:

• Description of novel surgical techniques for single or multiple chord replacement.
• Utilizing expanded polytetrafluoroethylene (PTFE) sutures for chordal reconstruction.
• Focus on ensuring appropriate neochord length and secure anchoring.

Main Results:

• The described maneuvers provide safe and reproducible results for chord replacement.
• Expanded polytetrafluoroethylene (PTFE) sutures offer a durable and simpler alternative for chordal reconstruction.
• These techniques aim to improve the management of anterior mitral leaflet prolapse.

Conclusions:

• Simple surgical maneuvers for PTFE chord replacement ensure reproducible results.
• This approach offers a reliable solution for anterior mitral leaflet prolapse.
• Enhanced mitral valve repair techniques contribute to superior patient outcomes.
