Longer Warfarin Therapy After Bioprosthetic Aortic Valve Replacement May Be Beneficial

Three months of warfarin is the usual standard of care following bioprosthetic aortic valve replacement (AVR),  although the supporting evidence base for this practice is limited. A new, large registry study published in JAMA suggests that more-prolonged warfarin therapy may be beneficial. Danish researchers identified 4075 patients who underwent bioprosthetic AVR. As expected, warfarin treatment between 30 and […]

TCT: Impressive Survival Benefit for TAVR in Inoperable Patients at 3 Years

At the TCT meeting in Miami, Murat Tuzcu presented the latest findings from the PARTNER B trial comparing transcatheter aortic valve replacement (TAVR) with standard therapy in patients who are not considered eligible for surgical valve replacement. At 3 years, the mortality advantage continued to grow for TAVR over standard therapy. All-cause mortality at 3 years: 80.9% […]
