Microinvasive mitral valve surgery: Current status and status quo

Area of Science:

• Cardiovascular Surgery
• Medical Technology Innovation

Background:

• Degenerative mitral valve disease necessitates effective treatment.
• Surgical mitral valve repair via sternotomy or minimally invasive approaches is the established gold standard.
• High repair rates and excellent durability are achieved in specialized centers.

Purpose of the Study:

• To evaluate the efficacy of novel mitral valve repair techniques.
• To compare outcomes of new techniques with traditional surgical repair.
• To assess the potential of off-pump mitral valve repair to match established results.

Main Methods:

• Review of current literature on surgical mitral valve repair techniques.
• Analysis of outcomes from centers with high surgical repair rates.
• Examination of emerging techniques for mitral valve repair without cardiopulmonary bypass.

Main Results:

• Traditional surgical mitral valve repair demonstrates high success and durability.
• New techniques allow mitral valve repair through smaller incisions and without cardiopulmonary bypass.
• The long-term results and reproducibility of these new techniques compared to surgical repair are currently under investigation.

Conclusions:

• Surgical mitral valve repair remains the gold standard for degenerative mitral valve disease.
• Novel techniques offer potential advantages but require further validation.
• The ability of new off-pump techniques to achieve comparable outcomes to established surgical repair is yet to be determined.
