Significance and distribution of aortic valve calcium score before TAVI

Abstract Introduction Aortic valve calcium scoring by multislice computed tomography (MSCT) is an alternative load independent assessment of aortic stenosis severity. Recent studies have further demonstrated that calcification related to adverse outcomes during and after transcatheter implantation (TAVI), however reference values in this population are uncertain. This study aimed assess P referred for TAVI. Methods Retrospective analysis consecutive patients (P) submitted TAVI between 2014 2020 a tertiary care centre. Clinical echocardiographic characteristics, along with MSCT-derived score were collected. Results A total 467 included, 57% female, median age 83 (9) years (minimum 45 maximum 95 years-old). The prevalence hypertension, dyslipidemia diabetes was 83%, 69% 36%, respectively. Chronic renal failure present 51%, atrial fibrillation 34% peripheral artery disease 14%. Considering the 346 quantified MSCT, 2161 (1761) AU. Age did not correlate valvular (r=0.043, p=0.422). Male gender showed significantly higher (2800 (2093) vs 1850 (1584), p<0.001) (Figs. 1 2). 11P had bicuspid disease, being younger (75 (16) (8) years, p=0.001), nonetheless displaying (2599) 2112 (1788), p=0.025). weak but statistically significant correlation (r=0.366, mean gradients (r=0.387, area (r=−0.120, p=0.047) demonstrated. Valvular different reduced ejection fraction (<50%) (p=0.388). Conclusion There differences men women Higher associated increasing calcification. left ventricle related. distinct characteristics.
