This shows that closing small fenestrations that are far away from the primary interatrial defect without rims and using other devices instead, such as a PDA coil, is feasible and can avoid the need for an open-heart surgical procedure; moreover, it is important to note that leaving these fenestrations open can have the same physiology as a patent foramen oval.</p>","PeriodicalId":9435,"journal":{"name":"Cardiology in the Young","volume":" ","pages":"1-4"},"PeriodicalIF":0.9,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142388305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
