Methods Ninety-five patients with complex congenital heart disease were treated from Nov.1989 to Feb.2000.The diagnosis included: transposition of the great artery, double outlet right ventricle, tetralogy of Fallot, persistent truncus arteriosus and aortic stenosis. The corrective operations were performed in 90 cases, and palliative operations in 5 cases. Results The hospital mortality was 13.7%, and 68 cases were followed up from 1 month to 8 years postoperatively with 25 cases showed calcification in VHC by chest X-ray, but only 5 cases had mild to moderate pressure gradient across the conduit. Conclusion VHC can be used to treat almost all kind of congenital heart diseases; aortic VHCs are liable to calcificate than pulmonic VHCs; to keep the VHC in good condition, programed cooling, cryopreserving and two-stage melting were important and should always be concerned with VHC infection.","PeriodicalId":67796,"journal":{"name":"中国胸心血管外科临床杂志","volume":"14 1","pages":"205-207"},"PeriodicalIF":0.0,"publicationDate":"1998-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69751099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
