Transcatheter aortic valve replacement: historical perspectives, current evidence, and future directions.

Severe aortic stenosis (AS) results in considerable morbidity and mortality without aortic valve replacement and is expected to increase in prevalence with the aging population. Because AS primarily affects the elderly, many patients with comorbidities are poor candidates for surgical aortic valve replacement (SAVR) and may not be referred. Transcatheter aortic valve replacement (TAVR) has emerged as transformative technology for the management of AS over the past decade.

Warfarin: Impact on hemostasis after radial catheterization.

Objectives: This study explores bleeding risk of warfarin patients undergoing radial catheterization.

Background: Traditionally warfarin has been held prior to catheterization due to bleeding risk; however, this practice is being reconsidered with radial access. This study examined if radial patients receiving warfarin have similar hemostasis times to those not taking warfarin.
