  • Meta-analysis of non-vitamin K antagonist oral anticoagulant vs. vitamin K antagonist treatment in patients after transcatheter aortic valve implantation with high-risk atrial fibrillation: Systematic review and meta analysis

    ObjectiveTo systematically evaluate the effects of non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists (VKA) on postoperative anticoagulation in patients undergoing transcatheter aortic valve implantation (TAVI) with combined high-risk atrial fibrillation (AF). MethodsAll clinical research literature on NOAC and VKA in TAVI patients with high-risk AF was collected using computer searches of PubMed, EMbase, The Cochrane Library, CNKI, VIP, and SinoMed. The retrieval schedule was from inception to January 2023. The Newcastle-Ottawa Scale (NOS) was utilized to provide an assessment of the quality of the included literature. Meta-analysis was performed by applying RevMan 5.4 software to the studies that met the quality criteria. ResultsA total of 24 592 patients were incorporated in 7 eligible papers for meta-analysis. Patients with NOAC had a significantly lower risk of all-cause mortality compared with TAVI patients with combined high-risk AF who had VKA [RR=0.74, 95%CI (0.58, 0.94), P=0.01]. During the first year of follow-up, no apparent difference in all-cause mortality was observed between the two groups [RR=0.57, 95%CI (0.17, 1.88), P=0.35]. After a year of following up on patients treated with VKA, all-cause mortality was higher in the group treated with NOAC, and the difference was statistically meaningful [RR=0.73, 95%CI (0.57, 0.95), P=0.02]. Patients in both groups had early stroke [RR=0.50, 95%CI (0.19, 1.28), P=0.15], follow-up stroke [RR=1.04, 95%CI (0.88, 1.22), P=0.64] and bleeding [RR=0.94, 95%CI (0.73, 1.21), P=0.61], severe or life-threatening hemorrhage [RR= 0.80, 95%CI (0.49, 1.31), P=0.38], and acute kidney injury [RR=0.51, 95%CI (0.16, 1.59), P=0.24] were all non-statistically significant differences. ConclusionCompared with the application of VKA, postoperative anticoagulation with NOAC in TAVI patients with combined high-risk AF may reduces all-cause mortality in patients and may yield additional benefit especially in long-term anticoagulation.
