Population trends in mitral valve surgery in Finland between 1997 and 2014: the finnish CVD register
<h4>OBJECTIVES:</h4><p>Contemporary, nationwide data on trends in mitral valve surgery are scarce. Our aim was to investigate changes in procedure rates, patient selection, and post-procedural prognosis of open-heart mitral ...
Anticoagulation Therapy After Biologic Aortic Valve Replacement
<p><strong>Objectives:</strong> Thromboembolism prophylaxis after biologic aortic valve replacement (BAVR) is recommended for 3 months postoperatively. We examined the continuation of oral anticoagulation (OAC) treatment and its effect on the long-term prognosis after BAVR.</p><p><strong>Methods:</strong> We used nation-wide register data from 4,079 individuals who underwent BAVR. We examined the association between warfarin and the non-vitamin K antagonist oral anticoagulant use with death, stroke and major bleeding in 2010 – 2016.</p><p><strong>Results:</strong> The risk of stroke was higher (HR 2.39, 95% CI 1.62 – 3.53, p < 0.001) and the risk of death was lower (HR 0.79, 95% CI 0.65 – 0.96, p = 0.016) in OAC-users compared to individuals without OAC. We observed no significant associations between OAC use and bleeding risk.</p><p><strong>Conclusion:</strong> OAC use after BAVR was associated with increased risk of stroke and decreased risk of death. These observational findings warrant validation in randomized controlled trials before any clinical conclusions can be drawn.</p>...
