Introduction Aortic stenosis is the most common valve disease in patients aged over 65 years. The natural history of severe symptomatic aortic stenosis without treatment is poor, resulting in a 50% two-year survival and only 3% five-year survival. Trans-catheter aortic valve implantation (TAVI) is a well- established treatment for severe aortic stenosis in high-risk surgical patients. However, the waiting time for TAVI is increasing. Computed Tomography for TAVI (CT TAVI) is an essential work up before TAVI.

Purpose The purpose of this study is to analyse waiting times for CT TAVI after evaluation by the heart team.

Method The study was carried out at a large district non-surgical hospital in the UK with well-established CT TAVI service. All patients who had CT TAVI scan from April 2021 to June 2023 were included.

Result A total of 75 patients (mean age 80.5±9.2 years) were identified who had CT TAVI scan. 82% of the scans were requested as outpatient and 18% were requested as inpatient. The mean time to CT TAVI from the date of request was 44±35 days, with only 52% of patients receiving their scan within 42 days. Notably, 20% of patients experienced wait times exceeding 70 days. Only 30 patients (40%) of those who had CT TAVI underwent TAVI procedure.

Conclusion This single centre retrospective observational study demonstrates significant delays in TAVI waiting times. CT TAVI waiting times appear to be a rate limiting factor in causing delay to TAVI treatment. Urgent action is required for a robust strategy and policy aimed at improving CT TAVI service and reducing waiting times.
