Background Suprasternal access is an alternative access strategy for transcatheter aortic valve replacement (TAVR) where the innominate artery is cannulated from an incision above the sternal notch. To date, suprasternal access has never been compared with transfemoral TAVR. Thus, we sought to assess safety, feasibility, and early clinical outcomes between suprasternal and transfemoral access for patients undergoing TAVR. Methods and Results We evaluated patients from 2 institutional prospective, observational registries containing 1348 patients. Patients were selected in a 2:1 ratio (transfemoral:suprasternal) on the basis of propensity score matching. The primary outcome was in-hospital mortality, and secondary outcomes included the incidence of ischemic stroke, major bleeding, vascular injury, left bundle-branch block, and permanent pacemaker implantation at 30-day follow-up. Propensity score matching identified 89 patients undergoing suprasternal TAVR and 159 patients undergoing transfemoral TAVR suitable for analysis. There was no significant difference between suprasternal TAVR and transfemoral TAVR with respect to in-hospital mortality (1.1% versus 0.6%; odds ratio [OR], 1.80; 95% CI, 0.11-29.06; P =0.680). No patients in either cohort suffered an ischemic stroke. The incidence of major bleeding (2.2% versus 2.5%; OR, 0.89; 95% CI, 0.16-4.96; P =0.895) and vascular injury (1.1% versus 1.9%; OR, 0.59; 95% CI, 0.06-5.77; P =0.651) did not differ significantly. The frequency of left bundle-branch block (9.4% versus 15.8%; OR, 0.56; 95% CI, 0.24-1.30; P =0.177) and permanent pacemaker implantation (11.2% versus 5.9%; OR, 2.01; 95% CI, 0.75-5.45; P =0.169) were not statistically significantly different. Conclusions Suprasternal TAVR was safe and achieved promising short-term clinical outcomes when compared with transfemoral TAVR. Future studies seeking to identify the optimal alternative access site should evaluate suprasternal TAVR access alongside other substitutes for transfemoral TAVR.

Objectives: To describe outcomes after suprasternal (SS) transcatheter aortic valve replacement (TAVR) as a new alternative access approach., Background: There still remains a cohort of the TAVR population who are not suitable for a transfemoral (TF) approach. SS-TAVR is a safe and effective alternative to TF-TAVR and has now become our preferred alternative access route., Methods: We retrospectively reviewed all patients from New York Presbyterian Hospital, Columbia University Medical Center and Princeton Baptist Medical Center who underwent SS-TAVR from 2015 to July 2018. A total of 84 patients were included in the study., Results: Technical success was achieved in all cases. Thirty-day survival was 98.8% (n = 83). There were minimal complications. Most notably, there were no transient ischemic attacks or strokes (0%, n = 0). Reexploration for bleeding was 3.6% (n = 3), and major bleeding was 1.7% (n = 1). We also achieved satisfactory results with a mean aortic valve gradient of 6.07 ± 3.79 mmHg and an aortic valve area of 2.21 ± 0.51 cm 2 . No patients had anything more than mild paravalvular leak. The mean length of stay (LOS) in the intensive care unit was 1.42 ± 1.23 days, and hospital LOS was 4.20 ± 3.29 days., Conclusions: SS access for TAVR is an extremely important technique to have in any valve team's alternative access armamentarium. This technique can be safely and reliably reproduced with any standard hybrid operating room setup and no additional equipment, and it can be used with any commercially available valve system. In the current experience, minimal complications and excellent early term results were obtained., (© 2019 Wiley Periodicals, Inc.)
