Transcatheter aortic valve implantation at a high-volume center: the Bad Rothenfelde experience

Introduction The "transfemoral (TF) first" approach to access route selection in transcatheter aortic valve implantation (TAVI) is popular; however, the risk of major vascular complications is substantial. The "best for TF" approach identifies only the patients with ideal anatomy for TF-TAVI, potentially minimizing complications. Aim To characterize the outcomes of patients undergoing TAVI at a large-volume site that employs this approach. Material and methods Patients who underwent TAVI at the Bad Rothenfelde Heart Centre between 2008 and 2016 were consecutively enrolled. Findings were compared to those from large, multicenter registries. Results Of the 1,644 patients enrolled, 1,140 underwent TA- and 504 TF-TAVI. Comorbidities were more frequent in TA patients, who also had higher risk scores (EuroSCORE: 25.5% vs. 21.2%; STS score: 11.0% vs. 7.5%; p < 0.001 for both). Rates of conversion to open surgery, major vascular complications and intra-procedural mortality did not differ between groups. At 30 days, mortality rates were higher in the TA group (3.9% vs. 1.9%, p = 0.036). Stroke/transient ischemic attack and permanent pacemaker implantation rates did not differ significantly between groups (2.0% and 9.1% overall, respectively). Compared to multicenter registries, trends in mortality and complication rates were similar, though magnitudes were lower in the present study. In contrast with the present study, major vascular complication rates in multicenter registries are significantly higher for TF compared to TA patients. Conclusions At this high-volume center, the use of a "best for TF" approach to TAVI resulted in low mortality and complication rates.
