[Minimally Invasive Mitral Valve Plasty;My Technique]

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques
• Thoracic Surgery

Background:

• Mitral valve plasty is a crucial procedure for treating mitral valve disease.
• Minimally invasive approaches aim to reduce surgical trauma and improve patient recovery.
• Endoscopic visualization offers potential advantages in precision and access during cardiac surgery.

Purpose of the Study:

• To describe a totally endoscopic minimally invasive mitral valve plasty technique.
• To evaluate the feasibility and methods of this endoscopic approach for mitral valve repair.

Main Methods:

• Utilized a 3-5 cm main incision in the right 4th intercostal space with additional trocar ports for instruments and camera.
• Employed a 3-dimensional endoscope for enhanced visualization.
• Performed mitral valve repair using resection and suture for posterior leaflet lesions and loop technique for anterior leaflet prolapse.
• Established cardiopulmonary bypass via femoral artery and vein cannulation, omitting jugular vein cannulation.

Main Results:

• Successfully performed mitral valve plasty under totally endoscopic view.
• Avoided the use of a median sternotomy and rib spreaders.
• Detailed specific techniques for posterior and anterior leaflet repair within the endoscopic framework.

Conclusions:

• Totally endoscopic minimally invasive mitral valve plasty is a feasible approach.
• This technique offers an alternative to traditional open-heart surgery for mitral valve repair.
• The use of 3D endoscopy enhances surgical precision in minimally invasive cardiac procedures.
