Clinical Leaflet Thrombosis in Transcatheter and Surgical Bioprosthetic Aortic Valves by Four-Dimensional Computed Tomography [1]
Basra and colleagues report that among patients with bioprosthetic aortic valves who had clinical or echocardiographic indications suggestive of leaflet thrombosis, one-third of patients had this diagnosis confirmed by four-dimensional computed tomography (4DCT). The use of 4DCT avoided unnecessary anticoagulation in the remaining two-thirds of patients. The median time from valve replacement to 4DCT was 9.6 months in transcatheter patients and 3.7 years in surgical patients, due to active surveillance in patients who had received a transcatheter valve.
