There are two types of annuloplasy rings: the rigid ring and the flexible ring. This study sought to examine the long-term results of mitral valve repair using a Duran flexible ring. METHODS: We retrospectively reviewed 226 patients who underwent primary mitral valve repair using the Duran flexible ring for mitral regurgitation between September 1994 and March 2003. Patients' mean age was 56.7 years, and 39% were female. The mean follow-up was 10.6 years (0.04 ∼ 18.3), and echocardiographic follow-up was 83.3% complete. RESULTS: There were three early and 25 late deaths. Survival was 89.3 ± 2.2 for 10 years, and 83.5 ± 3.2% for 15 years. The 10- and 15-year freedom from reoperation on the mitral valve were 96.4 ± 1.4 and 95.3 ± 1.7%, respectively. The 10- and 15-year freedom from moderate or severe mitral regurgitation were 92.5 ± 2.2 and 73.7 ± 7.1%, respectively. Cox regression analysis revealed that age, male gender, and isolated anterior leaflet prolapse were predictive of recurrent moderate or severe mitral regurgitation. CONCLUSIONS: Mitral valve repair for mitral regurgitation using a flexible Duran ring is safe and durable for more than 10 years.","is_dataset_classified":null,"base_score":1.791759469228055,"endowment":1.791759469228055,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"25704138","pmcid":null,"openalex_id":"https://openalex.org/W1798779352","authors":[],"funders":[],"total_grants":0,"fwci":0.4317,"citation_percentile":0.67415813,"influential_citations":0,"citation_trend":[{"year":2017,"count":1},{"year":2018,"count":1},{"year":2019,"count":1},{"year":2020,"count":1},{"year":2021,"count":1}],"oa_status":"closed","license":"http://doi.wiley.com/10.1002/tdm_license_1.1","oa_locations":[{"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1111%2Fjocs.12522","host_type":"publisher"},{"url":"http://onlinelibrary.wiley.com/wol1/doi/10.1111/jocs.12522/fullpdf","host_type":"publisher"},{"url":"https://doi.org/10.1111/jocs.12522","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/25704138","host_type":"repository"}],"fields_of_study":["Cardiac Valve Diseases and Treatments","Congenital Heart Disease Studies","Aortic Disease and Treatment Approaches"],"mesh_terms":["Adult","Age Factors","Aged","Female","Follow-Up Studies","Humans","Male","Middle Aged","Mitral Valve Insufficiency","Recurrence","Retrospective Studies","Severity of Illness Index","Sex Factors","Time Factors","Survival Rate","Proportional Hazards Models","Treatment Outcome","Mitral Valve Annuloplasty"],"keywords":["Medicine","Mitral regurgitation","Mitral valve repair","Mitral valve","Cardiology","Internal medicine","Surgery","Mitral valve annuloplasty","Proportional hazards model"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Gender equality"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-29T11:42:48.508354Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
