Does transcatheter valve replacement increase the risk of subclinical leaflet thrombosis compared to surgical valve replacement?
Subclinical leaflet thrombosis is more common early (30 days) after transcatheter compared to surgical valve replacement, but this difference resolves by 1 year.
Subclinical leaflet thrombosis was more frequent in transcatheter compared with surgical valves at 30 days, but not at 1 year. The impact of HALT on thromboembolic complications and structural valve degeneration needs further assessment.
