Inclusion criteria
Inclusion criteria: 1.Age =18 years; 2.Diagnosis of moderate-to-severe or more severe commissural mitral regurgitation or mitral regurgitation involving commissural-adjacent regions, mainly involving the anterolateral or posteromedial commissure and adjacent A1/P1 or A3/P3 segments; 3.revious treatment with TEER or surgical mitral valve repair centered on the Magic Stitch technique; 4.Available baseline data, treatment records, and at least one postoperative follow-up outcome;
Exclusion criteria
Exclusion criteria: 1.The primary etiology is not degenerative or commissural-related mitral valve disease and is unsuitable for inclusion in the comparison; 2.Previous treatment with other transcatheter mitral valve therapies or prior mitral valve surgery that makes it impossible to evaluate the effect of the index treatment; 3.Severe missing key baseline or treatment data, making it impossible to determine whether the patient meets the study population definition; 4.Patients known to have previously explicitly refused the use of their clinical data for research; 5.The investigator judges that the authenticity or completeness of the data is insufficient for inclusion in the analysis;
