Abstract

Background: In patients who are not suitable for traditional access routes for transcatheter aortic valve replacement (TAVR) due to severe peripheral vascular disease (PVD) or prohibitive surgical risk, carotid artery (CA) access is an emerging route for TAVR. This study represents the most up to date on outcomes of carotid access TAVR. Methods: A systematic review was conducted as per the Preferred Reporting Instructions for Systematic Reviews and Meta-analysis (PRISMA). We performed a thorough electronic search through Pubmed, SCOPUS and Embase databases. Statistical analyses were performed using SPSS version 24 (IBM Corporation, Armonk, New York, USA). Results: A total of 15 non-randomized studies were included in this systematic review comprising of patients that received TAVR via 4 vascular access sites, transcarotid (TC) (N = 1035), transfemoral (TF) (N = 1116), transapical (TAP) (N = 307), transaortic (TAO) (N = 176) and transaxillary (TAX) (N = 90). In the Transcarotid cases, device success was achieved in 95.6% of patients (n = 748). The 30-day and 1-yr mortality was 4.2% and 10.5% respectively. 15.3% of patients required new pacemaker implantation. In-hospital stroke or TIA occurred in 4% of cases. 30-day stroke or TIA occurred in 5% of cases. There were no hemorrhagic strokes. 30-day Mortality was significantly higher in the Transaortic group (12.1%) compared to the Transcarotid group (2.6%) [RR = 2.93 95% CI = 1.15–7.58; p = 0.027]. There were no differences in outcomes between the Transcarotid group and the Transapical or Transaxillary groups. Conclusion: The most contemporary data on Carotid access TAVR shows impressive device success, low rates of stroke and pacemaker implantation and an acceptable 30-day and 1-year mortality. 30-day mortality was significantly lower in TC compared to TAO patients.
