The optimal valve substitute for patients between 60-70 years is controversial. We compared anticoagulation-related adverse events (ARAE) in patients receiving mechanical heart valve replacement (MHVR) on INR self-management vs. stentless bioprosthesis, to assess whether the risk of structural valve deterioration (SVD) is still out-weighted by the benefit of not requiring permanent anticoagulation.

Mechanical Heart Valve Replacement

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Retrospective

Further study details as provided by Johann Wolfgang Goethe University Hospitals:

Group A
Group A patients received mechanical heart valve replacement MHVR (and were educated in INR self-management using the Coagu-Check monitor.
Group B
Group B patients received MHVR and their anticoagulation was managed by their general practitioners.
Group C
Group C patients received stentless bioprosthesis, with initial 6 weeks on oral anticoagulation managed by their general practitioners.
