Patients with CMA > 30° presented smaller aortic annulus (23.8 vs. 20.7, <i>p</i> < 0.01) and received smaller valves. There was a slight increase of mean transvalvular gradient during follow-up (9.2−10.3 mmHg, <i>p</i> < 0.05), without significant differences between groups. Mortality rate was 16.2% at 1 year and 49.5% at 5 years; and not related to commissural alignment.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Significant CMA is present in 40% of patients treated with SAPIEN 3 valves, however, we didn't find a significant association between CMA and gradient increase or mortality during long-term follow-up.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9650,"journal":{"name":"Catheterization and Cardiovascular Interventions","volume":"105 5","pages":"1067-1076"},"PeriodicalIF":2.1,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
