Background: Transcatheter aortic valve replacement (TAVR) provides therapy for patients with severe aortic stenosis at extreme, high, or intermediate surgical risk. Transfemoral access has been the preferred access route; however, this approach is not suitable for many TAVR candidates. A suprasternal approach may allow for earlier ambulation and shorter hospital stay as compared with other, nontransfemoral approaches. Methods: A total of 11 patients with unsuitable transfemoral access underwent suprasternal TAVR. Propensity matching was used to compare suprasternal patients to patients undergoing transaortic, transapical, and trans-subclavian TAVR. Results: Groups were well matched for baseline characteristics. A self-expanding valve device was used in 6 (54.5%) and a balloon-expandable valve in 5 (45.5%) of the 11 patients treated by the suprasternal route. Suprasternal and trans-subclavian patients were able to ambulate earlier than patients treated by the transaortic route, a median 1.6 days (interquartile range [IQR]: 0.9 to 1.8), 1.6 days (IQR: 0.9 to 2.7), and 3.9 days (IQR: 1.9 to 4.5) after the procedure for suprasternal, trans-subclavian, and transaortic patients, respectively (p = 0.001). Length of hospitalization was shorter for patients treated by suprasternal or trans-subclavian access in comparison with patients treated by the transaortic or transapical approach: median 4 days (IQR: 3 to 8) and 4 days (IQR: 4 to 8) versus 8 days (IQR: 6 to 14) and 6 days (IQR: 7 to 11) for suprasternal and trans-subclavian versus transaortic and transapical, respectively (p = 0.01). Conclusions: Suprasternal and trans-subclavian access are associated with earlier ambulation and shorter hospitalization than other nontransfemoral TAVR routes, without an increase in complications. Further study is required to determine if suprasternal is the alternative access of choice for TAVR patients with poor transfemoral vasculature.
