Chest tube clearance strategies (CTCSs) were developed to improve CT patency. Our meta-analysis compared the safety and efficacy of CTCS versus CT following cardiac surgery. The PubMed/MEDLINE, Embase, Web of Science, and Scopus databases were searched from 1946 to 2023 for studies that compared CTCS to CT. Two investigators independently reviewed, screened, extracted, and assessed the data prior to performing a random effects meta-analysis using R. The primary outcome was re-exploration and the secondary outcomes were retained blood syndrome, mortality, blood products, stroke, cardiac arrest, atrial fibrillation, ventilation time, intensive care unit (ICU) time, hospital length of stay, and chest drainage. Five studies (2288 patients) were included. There were two clinical trials (<i>n</i> = 620) and three observational studies (1668 patients). Compared to CT, CTCS had a significant reduction of postoperative atrial fibrillation (risk ratio (RR) 0.80, 95% CI 0.70 to 0.92, <i>I</i>² = 17%, <i>p</i> &lt; 0.01). There was no significant difference in re-exploration, retained blood syndrome, hospital length of stay, and ICU length of stay.

The morphological types of IAA were described in accordance with Celoria–Patton classification. <i>Results</i>. IAA was seen in 49 patients (32 males and 17 females; mean age: 15.9 months). The most common type of IAA based on the site of interruption was type A seen in 27/49 (55.1%) patients, while type B was observed in 22/49 (44.9%) patients. No patient of type C IAA was encountered in the current series. The most commonly associated cardiovascular anomaly was patent ductus arteriosus (PDA) seen in 45/49 (91.8%) patients. Atrial septal defect was seen in 15/49 (30.6%) patients, while 39/49 (79.6%) patients had a ventricular septal defect (VSD). Common arterial trunk was the most common abnormal ventriculo-arterial connection seen in 13/49 (26.5%) patients. Aorto-pulmonary window was associated with 7/49 (14.3%) patients. <i>Conclusion</i>. IAA is a rare congenital heart defect associated with an array of cardiovascular anomalies, most common being PDA and VSD. CT angiography is useful not only in diagnosing and characterizing the IAA but also in identifying associated anomalies which may have a bearing on the clinical presentation, prognosis, and surgical management.</p>\u0000 </div>","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":"2024 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5552627","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142152343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
