Abstract EN
Low-flow low-gradient severe aortic stenosis (LFLGAS) is associated with worse outcomes.
Aortic valve calcification patterns of LFLGAS as compared to non-LFLGAS have not yet been thoroughly assessed.
137 patients undergoing transcatheter aortic valve replacement (TAVR) with preprocedural multidetector computed tomography (MDCT) and postprocedural transthoracic echocardiography were enrolled.
Calcification characteristics were assessed by MDCT both for the total aortic valve and separately for each leaflet.
34 patients had LFLGAS and 103 non-LFLGAS.
Total aortic valve calcification volume (p<0.001), mass (p<0.001), and density (p=0.004) were lower in LFLGAS as compared to non-LFLGAS patients.
At 30-day follow-up, mean transaortic pressure gradients and more than mild paravalvular regurgitation did not differ between groups.
In conclusion, LFLGAS and non-LFLGAS express different calcification patterns which, however, did not impact on device success after TAVR.
