Aortic Stenosis - Prognosis, Risk and Outcomes

Summary

The investigators will prospectively enroll 300 patients undergoing TAVI at Sahlgrenska University Hospital, which is the second largest TAVI hospital in Sweden. Eligible patients should have a clinical indication for aortic valve replacement with TAVI and have preprocedural clinical investigations with echocardiography (UCG) and CCT and provide written informed consent. UCG, electrocardiogram (ECG) and blood samples will be taken in addition to clinical status, NYHA-class and collection of outcome events the day before the procedure, 1±2 hours, 24 ±6hours and daily after the procedure until discharged from Sahlgrenska. Further follow-up will be scheduled day 14, 30, 180, 365 and yearly. Cardiac MRI will be performed before, at 14 days and at 180 days after TAVI. Brain MRI will be performed before and 24± hours after TAVI. Cardiac CT will be performed at 180 days after TAVI.
