ObjectiveTo explore the effect of using a stent graft to treat a Stanford type A aortic dissection with the ascending aorta in the cavity.MethodA retrospective review was made of the clinical data of a patient with Stanford type A aortic dissection admitted to Zhangye People’s Hospital Affiliated to Hexi University in December 2016.ResultsAfter the patient underwent general anesthesia aortic dissection and stent graft treatment, the dissection fracture completely disappeared. After 2 years of follow-up, the patient’s pseudocavity hematoma was completely absorbed. The operative time was 30 min and the blood loss was about 5 mL. There were no complications such as avulsion of dissection, internal leakage, cerebral infarction, myocardial infarction, nervous system, and other complications occurred.ConclusionFor Stanford type A aortic dissection with a tear located in the ascending aorta, intracavitary treatment with coated stent is feasible for ascending aortic dissection with good vascular conditions and tear location through accurate preoperative assessment.
ObjectiveTo evaluate the clinical outcomes of sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) for aortic valve disease. MethodsWe conducted a computer-based search of databases including CNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase and Web of Science from the inception of the databases to March 2024. Two reviewers independently screened articles, extracted data and used the Cochrane bias risk assessment tool to evaluate the quality of the included studies. Meta-analysis was performed using Stata 18 software. ResultsThe included 17 studies using propensity-matched analysis consisted of 6 630 patients, including 3 319 patients in the SU-AVR group and 3 311 patients in the TAVI group. The SU-AVR group had lower mortality than the TAVI group at 1-year ［RR=0.58, 95%CI(0.38, 0.87), P=0.009］, 2-year ［RR=0.61, 95%CI(0.43,0.85), P=0.004］ and 5-year ［RR=0.63, 95%CI(0.50,0.79), P=0.000］. The SU-AVR group had a significantly lower rate of new permanent pacemaker implantation (PPI) ［RR=0.75, 95%CI(0.58, 0.98), P=0.037］, moderate-to-severe paravalvular leak (PVL) ［RR=0.20, 95%CI（0.12, 0.32）, P=0.000］, myocardial infarction(MI)［RR=0.30, 95%CI (0.11,0.80), P=0.017］, more-than-mild residual aortic regurgitation (AR)［RR=0.29, 95%CI（0.17, 0.48）, P=0.000］. In addition, the SU-AVR group had a higher postoperative mean aortic gradient [SMD=0.39, 95%CI (0.17, 0.62), P=0.000］than the TAVI group. Conclusion The early and mid-term clinical outcomes of SU-AVR were superior compared to TAVI.
