Early post-implantation valve thrombosis may brood occur in up to 15 of patients; it is possible that valve thrombosis, even if subclinical or successfully treated with anticoagulants, might trigger inflammation and a subsequent fibrocalcific remodeling of valve leaflets. Low stent base maximizes coronary ostia clearance. To date, there is no unified definition of svd. Clinically-relevant svd: 20 mm Hg increase in mean transvalvular gradient with concomitant decrease in eoa.6 cm2 and/or decrease in Doppler velocity index.15 during follow-up, leading to severe aortic stenosis; and/or new onset of or increase by at least 1 grade of intra-prosthetic.

The treatment for bioprosthetic surgical valve dysfunction conventionally has been re-do surgery. Perimount pericardial bioprosthesis for aortic calcified stenosis: 18-year experience with 1,133 patients. Stenosis may be more common with stented valves, and leaflet tear and regurgitation with stentless valves. Based on a proven design with published hemodynamic stability up to 17 years post-implantation8. The authors recommend repeating tte between 1- and 5-year follow-up, and yearly thereafter. For example, gluteraldehyde fixation decreases but does not eliminate bioprosthesis tissue antigenicity, and an immune response may be triggered that results in accelerated tissue mineralization.
