Since TAVI involves multimodality imaging to screen patients it is highly important to standardize the report and the analysis process of the AO valve.
Our aim .– To explore whether the precise location of the annulus calcifications could predict periprosthetical aortic regurgitation (PAR) after TAVI.
Method .– We propose a standardized aortic annulus description based on a “clock” segmentation. Cardiac CT was performed in 49 patients before and after TAVI and compared to the echo after TAVI. Aortic Annulus was divided into 12 quadrants. Six o’clock was defined as the insertion of interatrial septum on the aortic annulus. The calcic protrusion was assessed as the thickness of calcic annular apposition.
