    Abstract:
    A few studies recently reported controversial results with transfemoral transcatheter aortic valve replacement (TF-TAVR) versus transapical transcatheter aortic valve replacement (TA-TAVR), often without adequate adjusted analysis for baseline differences. Data on patients who underwent TF-TAVR and TA-TAVR from the Observational Study of Effectiveness of avR-tavI procedures for severe Aortic stenosis Treatment study were analyzed with propensity score 1-to-1 matching. From a cohort of 1,654 patients (1,419 patients underwent TF-TAVR and 235 patients underwent TA-TAVR), propensity score matching resulted in 199 pairs of patients with similar operative risk (EuroSCORE II: TF-TAVR 8.1 ± 7.1% vs TA-TAVR, 8.4 ± 7.3%, p = 0.713). Thirty-day mortality was 8.0% after TA-TAVR and 4.0% after TF-TAVR (p = 0.102). Postoperative rates of stroke (TA-TAVR, 2.0% vs TF-TAVR 1.0%, p = 0.414), cardiac tamponade (TA-TAVR, 4.1% vs TF-TAVR 1.5%, p = 0.131), permanent pacemaker implantation (TA-TAVR, 8.7% vs TF-TAVR 13.3%, p = 0.414), and infection (TA-TAVR, 6.7% vs TF-TAVR 3.6%, p = 0.180) were similar in the study groups but with an overall trend in favor of TF-TAVR. Higher rates of major vascular damage (7.2% vs 1.0%, p = 0.003) and moderate-to-severe paravalvular regurgitation (7.8% vs 5.2%, p = 0.008) were observed after TF-TAVR. On the contrary, TA-TAVR was associated with higher rates of red blood cell transfusion (50.0% vs 30.4%, p = 0.0002) and acute kidney injury (stages 1 to 3: 44.4% vs 21.9%, p <0.0001) compared with TF-TAVR. Three-year survival rate was 69.1% after TF-TAVR and 57.0% after TA-TAVR (p = 0.006), whereas freedom from major adverse cardiovascular and cerebrovascular events was 61.9% after TF-TAVR and 50.4% after TA-TAVR (p = 0.011). In conclusion, TF-TAVR seems to be associated with significantly higher early and intermediate survival compared with TA-TAVR. The transfemoral approach, whenever feasible, should be considered the route of choice for TAVR.
