Apex was orientated at a 90 degrees’ clockwise to right. Then aorta, inferior and superior vena cava and last pulmonary artery were anastomosed continuously. The prosthetic conduits were also used owing to a lack of tissue. \u0000 \u0000 \u0000Results \u0000All operations were successful. The cold ischemic time was (130-375)(251.00±122.53) min, cardiopulmonary bypass time (127-212)(179.67±55.72) min and aortic clamp time (38-105)(65.33±35.166) min. Two patients had stable hemodynamics and recovered well after HTx. During a follow-up period of 1.5-3.5 years, echocardiography showed excellent cardiac functions without blood flow obstruction. Chest radiology showed well-placed donor heart in right mediastinum. One left-sided patient with total cavopulmonary connection before HTx died at 59 days after HTx because of pneumonia and multiple organ failure. \u0000 \u0000 \u0000Conclusions \u0000Heart transplantation is curative for patients with congenital dextrocardia and surgical strategies are the key factor of successful treatment. \u0000 \u0000 \u0000Key words: \u0000Congenital heart disease; Dextrocardia; Heart transplantation","PeriodicalId":9885,"journal":{"name":"Chineae Journal of Organ Transplantation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83606748","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}
