چکیده
Objectives BSCI/BSTI guidelines recommend reporting aortic valve calcification (AVC) on all chest CT regardless of scan indication. Formal calcium scoring can identify stenosis but the clinical impact routine is unclear. This study assessed AVC prevalence, prognosis and association between (AS) echocardiography. Methods Retrospective, single-centre analysis consecutive CTs (January-December 2015) for 200 patients per age group (<40, 40-49, 50-59, 60-69, 70-79, 80-89, ≥90). were re-reviewed presence severity coronary artery (CAC). Corresponding echocardiography reports reviewed AVC/sclerosis AS. Comorbidities outcomes (myocardial infarction, stroke all-cause mortality) recorded included patients. Results 1377 (mean 64±20 years, 55% female) following exclusion with incomplete imaging data or prior replacement. 42% (587/1377) had a corresponding report within 5 years their (median time tests 3.9 months, [IQR 0.3 - 14.7]). On re-review, was observed in 508/1377 (37%), no significant difference males females (p=0.876).

Valve Calcification in Aortic Stenosis: Etiology and Diagnostic Imaging Techniques
Aortic stenosis is the most common valvulopathy in the Western world. Its prevalence has increased significantly in recent years due to population aging; hence, up to 8% of westerners above the age of 84 now have severe aortic stenosis (Lindroos et al., 1993). This causes increased morbidity and mortality and therein lies the importance of adequate diagnosis and stratification of the degree of ...

To the Editor: Rajamannan et al1 addressed the problem of bone formation in calcified aortic valves, quoting the publication of actual bone formation by Mohler et al.2 Mohler et al had indicated that ossification in calcified aortic valves was relatively common, finding evidence of valve ossification in 36 of 323 patients. Of historical interest, I reported ossification in the left ventricular ...
