Learning objectives To evaluate the correlation between radiological findings obtained from pre‑TAVI CT scans and the subsequent decision-making regarding prosthesis sizing, access route selection, and complication prediction—aiming to optimize outcomes and minimize risks in patients with severe aortic stenosis.
Read more Background Study Design and Population A retrospective, observational, and descriptive study conducted at the Hospital Universitario de Álava. A total of 101 patients underwent a pre‑TAVI CT scan from May 2019 to October 2022. Patients scheduled for interventions other than TAVI (e.g., Valve-in-Valve, TMVR) were excluded.• Data Acquisition:Radiological data were obtained through the IMPAX system for image analysis, while clinical information was collected retrospectively from digital medical records, ensuring patient anonymity and data protection.• Variables Analyzed: • Quantitative Variables: Patient age, native valve...
Read more Findings and procedure details Intervention and Demographics: Out of 101 patients, 80 (79.21%) underwent TAVI, with an average age of 81.2 years—significantly lower than the average age (83.8 years) of the non‑TAVI group. Although gender was not significantly associated with the decision to perform TAVI, a negative association was observed with age, indicating that younger patients were more likely to be treated with TAVI. Prosthesis Selection and CT Findings: Pre‑TAVI CT measurements enabled precise determination of the native valve dimensions, facilitating optimal prosthesis sizing. The strong correlation between CT‑measured...
Read more Conclusion  • Pre‑TAVI CT is an essential component of preoperative planning, providing accurate measurements of native valve dimensions that are critical for selecting the appropriate prosthesis size.• The high correlation between CT measurements and the prosthesis size confirms the value of detailed CT assessment in minimizing sizing discrepancies and reducing potential complications.• The choice of prosthesis model significantly influences the incidence of perioperative complications, emphasizing the need for individualized treatment strategies based on anatomical and clinical characteristics.• Factors such as male...
