Transcatheter aortic valve replacement (TAVR) is a valid option for patients with high or intermediate surgical risk. However, clinical outcomes of TAVR in low-risk patients are lacking. Our aim was to evaluate the efficacy and safety of TAVR versus surgical aortic valve replacement (SAVR) in low-surgical-risk patients.

Electronic database review was conducted for all randomized clinical trials (RCTs) that compared TAVR versus SAVR in low-risk patients. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) using a random-effects model.

We included 3 RCTs totaling 604 patients (310 TAVR and 294 SAVR). Our results showed no significant difference in mortality between TAVR compared with SAVR (RR = 0.71; 95% CI = 0.22–2.30; P = 0.56), however, there was a significantly increased risk of pacemaker implantation (RR = 7.28; 95% CI = 3.94–13.42; P < 0.01 …
