ABSTRACT
<p><b>BACKGROUND</b>Transcatheter aortic valve implantation (TAVI) has emerged as the treatment choice for non-operable patients with severe symptomatic aortic stenosis (AS) and may be a good alternative to surgery for those at very high or prohibitive surgical risk. We performed a meta-analysis to evaluate the comparative benefits of TAVI versus surgical aortic valve replacement (SAVR) in patients with severe AS.</p><p><b>METHODS</b>A comprehensive literature search of PubMed, Embase, ScienceDirect and Cochrane Central Register of Controlled trials was performed, and randomized trials as well as cohort studies with propensity score analysis were included.</p><p><b>RESULTS</b>One randomized trial (n = 699) and six retrospective cohort studies (n = 781) were selected for meta-analysis. Mortality at 30-day and 1-year follow-up was comparable between TAVI and SAVR. Despite similar incidences of stroke, myocardial infarction, re-operation for bleeding, and renal failure requiring dialysis, TAVI was associated with a lower occurrence rate of new-onset atrial fibrillation (OR 0.51, 95%CI 0.33 - 0.78) and shorter procedural time (mean difference -67.50 minutes, 95%CI -87.20 to -47.81 minutes). Post-operative aortic regurgitation and permanent pacemaker implantation were more common in patients after TAVI than in those with SAVR (OR 5.53, 95%CI 3.41 - 8.97; OR 1.71, 95%CI 1.02 - 2.84, respectively).</p><p><b>CONCLUSION</b>In patients with severe symptomatic AS, TAVI and SAVR did not differ with respect to short- and mid-term survival, but the incidence of permanent pacemaker implantation and post-procedural aortic regurgitation remain relatively high after TAVI.</p>
