Background: Recently, the carotid artery has been used as an alternative approach for transcatheter aortic valve implantation (TAVI). The aim of this study was to prove the safety and feasibility of transcarotid (TC) vs. transfemoral (TF) TAVI.
Methods and results: This retrospective study enrolled 726 consecutive patients with severe symptomatic aortic stenosis. All patients underwent TC-TAVI or TF-TAVI at Hôpital Haut-Lévèque, Bordeaux Heart University Hospital between September 2012 and October 2017. The TC-TAVI (n=83) and TF-TAVI (n=643) groups were compared statistically. The EuroSCORE II was significantly higher (8.2±6.7 vs. 6.4±5.5; P=0.007) and rates of current smoking, dyslipidemia and peripheral arterial disease were higher in the TC-TAVI than TF-TAVI group. All TC-TAVIs and 9.3% of TF-TAVIs were performed under general anesthesia. Radiation time was significantly shorter in the TC-TAVI than TF-TAVI group (14.5±6.0 vs. 23.0±10.8 min; P<0.001). Postimplant balloon valvuloplasty was performed more frequently in the TF-TAVI than TC-TAVI group (7.2% vs. 19.4%; P=0.006). Postoperative echocardiographic data were similar between the 2 groups, and there were no significant differences in 30-day mortality (8.4% vs. 5.0%; P=0.189) or stroke rate (1.2% vs. 2.6%; P=0.428) between the TF-TAVI and TC-TAVI groups.
Conclusions: The feasibility and 30-day safety of TC-TAVI and TF-TAVI are similar. When TF-TAVI is not suitable anatomically for a particular patient, TC-TAVI is a preferable alternative.

The gold-standard transfemoral (TF) access for transcatheter aortic valve implantation (TAVI) is not suitable in 10% to 15% of patients, and alternative accesses are needed. Studies have suggested that the transcervical (TC) access might yield outcomes comparable to the TF access. In our center, TC-TAVI is the first-line alternative to TF-TAVI.

Background: Despite the gold-standard approach for transaortic valve implantation (TAVI) remains transfemoral (TF), alternative approaches are needed in patients who present contraindications to transfemoral access.
Case Summary: We report the case of a 79-year-old female with a symptomatic high-gradient severe aortic stenosis-mean gradient of 43 mmHg-and a significant supra-aortic trunk stenosis (left carotid artery: 90-99%; right carotid artery: 50-70%), and who was hospitalized for progressive dyspnoea New York Heart Association (NYHA) stage III. In this high-risk patient, it was decided to perform a TAVI.

Background: The carotid artery is an alternative access route for transcatheter aortic valve implantation (TAVI), especially useful in patients unsuitable for traditional access routes including transfemoral (TF), subclavian, transapical, and aortic.
Aims: To investigate the feasibility and safety of transcarotid (TC) access for TAVI in comparison to the TF approach in a multicenter setting.
Methods: A total of 41 patients, treated between December 2014 and December 2018, were retrospectively reported to the Polish Registry of Common Carotid Artery Access for TAVI (POL-CAROTID).

Introduction: Transfemoral access (TF) is the preferred access for transcatheter aortic valve implantation (TAVI). Transcarotid TAVI (TC-TAVI) is an alternative for patients in whom TF-TAVI is impossible. Two types of valves - balloon-expandable (BE) and self-expandable (SE) - can be used in TC-TAVI procedures.

Objectives: The transcarotid (TC) approach for transcatheter aortic valve implantation (TAVI) is potentially an optimal alternative to the transfemoral (TF) approach. Our goal was to compare the safety and efficacy of TC- and TF-TAVI.
Methods: Patients who underwent TF-TAVI or TC-TAVI in the prospectively collected FRANCE TAVI registry between January 2013 and December 2015 were compared.
