Subclinical leaflet thrombosis in surgical and transcatheter bioprosthetic aortic valves: an observational study
The objective of this study was to report the prevalence of subclinical leaflet thrombosis in surgical and transcatheter aortic valves and the effect of novel oral anticoagulants (NOACs) on the subclinical leaflet thrombosis and subsequent valve haemodynamics and clinical outcomes on the basis of two registries of patients who had CT imaging done after TAVR or SAVR. Methods Patients enrolled between Dec 22, 2014, and Jan 18, 2017, in the RESOLVE registry, and between June 2, 2014, and Sept 28, 2016, in the SAVORY registry, had CT imaging done with a dedicated four-dimensional volume-rendered imaging protocol at varying int...

Claret Medical files for FDA clearance for Sentinel cerebral protection device
Claret Medical said today that it filed an application with the FDA seeking 510(k) clearance for its Sentinel cerebral protection system designed for use during transcatheter aortic valve replacements. The Santa Rosa, Calif.-based company’s Sentinel device is designed to capture and remove embolic debris dislodged during TAVR procedures, which can enter cerebral circulation and can potentially lead to strokes. “Our contribution in building significant new science will help the rapidly growing TAVR field embrace the critical role of cerebral protection in all left heart and endovascular procedures. These studi...
