Other related information

All included patients undergo four-dimensional contrast-enhanced cardiac computed tomography (CT) and transthoracic echocardiography (TTE) after the procedure to evaluate the incidence of bioprosthetic aortic-valve thrombosis and valve function.
Clinical follow-up is performed at 6 months and 1 year for the first year and annually thereafter along with CT and TTE analysis to clarify the clinical outcomes of thrombosis.
