Clinical outcomes of direct oral anticoagulant versus warfarin after transcatheter aortic valve replacement: From the STS/ACC TVT registry.
Journal Article Am Heart J · July 2025 BACKGROUND: Transcatheter aortic valve replacement (TAVR) recipients frequently have an indication for long-term oral anticoagulation, including atrial fibrillation or systemic thromboembolic disease. It remains unclear if there are differences in safety a ...

Journal Article Ann Biomed Eng · May 13, 2025 PURPOSE: Intervertebral disc (IVD) height fluctuates diurnally as the spine is exposed to periods of high and low loading. Therefore, accounting for loading history prior to measuring in vivo IVD height is important when investigating IVD mechanics. Howeve ...
