“…Especially in the old and frail TAVI population, potentially malignant incidental findings are common. [8][9][10][11][12][13] Following CTA, a dedicated team considers the patients' suitability for the procedure. Guidelines recommend denying TAVI if the estimated survival is <1 year.…”

Computed tomography angiography (CTA) in workup for transcatheter aortic valve implantation (TAVI) frequently reveals potentially malignant incidental findings. Most incidental findings provoke discussions on their influence. We aimed to analyze if these findings were a predictor of long-term survival after TAVI. In a single-center retrospective analysis, all consecutive patients with pre-TAVI CTA were included (years 2009 to 2014). Patients were divided by presence or absence of incidental findings. We analyzed up to 5 years of all-cause, non-cardiovascular and cardiovascular mortality for all 553 patients who underwent TAVI; 113 had a potentially malignant incidental finding (20.4%). At 5 years, all-cause mortality risk was 64.5% in patients with versus 49.1% in patients without a finding (hazard ratio [HR] 1.70, 95% confidence interval [CI] 1.25 to 2.31). After adjustment, the findings remained an independent predictor of all-cause (adjusted HR 1.46, 95% CI 1.07 to 1.99) and non-cardiovascular mortality (adjusted subdistribution HR 1.84, 95% CI 1.06 to 3.20), but not of cardiovascular mortality. In conclusion, the presence of potentially malignant incidental findings on CTA is an independent predictor of long-term all-cause and noncardiovascular mortality but not of cardiovascular mortality.

Introduction: Patients with severe aortic stenosis (AS) require multi-detector computed tomography (MDCT) when considered for transcatheter aortic valve implantation (TAVI). Incidental findings on MDCT are common given the age group and region imaged. Our aim was to evaluate the frequency and outcome of incidental findings (IF) identified on MDCT and the impact on survival.Methods: This single-centre analysis retrospectively reviewed severe AS patients who underwent MDCT during TAVI workup. MDCT reports were reviewed for any IF and defined into three categories: IF of no relevant clinical significance (IF-NoCS), IF of non-immediate clinical significance (IF-NICS) and IF of immediate clinical significance (IF-ICS). Demographics, follow-up of IF and survival were calculated from MDCT date. Results: Two hundred and sixty-five patients underwent MDCT for TAVI suitability (mean age 83 AE 6 years, 52% male). The majority proceeded to TAVI (65%). Renal lesions (25%) and lung nodules (18%) were the most common IF. Fifty-nine patients (22%) had IF-NICS; 39% (23/59) were benign, 59% were not further investigated and one patient had suspected lung cancer. Six patients (2.3%) had IF-ICS and all were diagnosed with lung cancer. During a median follow-up of 272 days, there was no survival difference between patients with IF-ICS or IF-NICS versus patients without IF or IF-NoCS in the overall cohort (P = 0.44) or in TAVI patients (P = 0.88). Conclusion: Incidental findings on MDCT are common with one-quarter having IF-ICS or IF-NCIS. Most patients with IF-NICS did not undergo further investigation. Standardized reporting of MDCT may assist in clarifying the need for further investigation which will in turn influence decision and timing to proceed with TAVI.

“Incidental findings” during TAVI work-up: more than just an inconvenience

Abstract: Incidental findings were associated with a longer time to TAVI procedure, lower chance of eventually receiving TAVI as definitive therapy and a worse overall outcome. Such findings are clearly important and should be taken into account when delivering a contemporary TAVI service.
