Anticoagulation or antiplatelet therapy of bioprosthetic heart valves recipients: an unresolved issue.
Improvements in the performance and longevity of biological valve prostheses have steadily increased their rates of implantation in recent years. Aortic bioprostheses, which are commonly used in the elderly or when the risks of anticoagulating are high, have generally been associated with low rates of long-term complications. Freedom from anticoagulation, therefore, represents the main theoreti...
متن کاملCardiac crossroads: deciding between mechanical or bioprosthetic heart valve replacement
Nearly 15 million people in the United States suffer from either aortic or mitral valvular disease. For patients with severe and symptomatic valvular heart disease, valve replacement surgery improves morbidity and mortality outcomes. In 2009, 90,000 valve replacement surgeries were performed in the United States. This review evaluates the advantages and disadvantages of mechanical and bioprosth...
متن کاملAntithrombotic therapy following bioprosthetic aortic valve replacement.
The life expectancy of the general population is increasing. This has meant that more elderly patients are requiring aortic valve replacement (AVR). The choice of valve replacement and its durability are important. Bioprosthetic (tissue) heart valves were introduced into clinical use in the 1960s and were developed primarily to reduce the complications associated with thromboembolism (TE) and t...
متن کاملAntiplatelet therapy early after bioprosthetic aortic valve replacement is unnecessary in patients without thromboembolic risk factors.
BACKGROUND The use of antithrombotic therapy during the postoperative period after biological aortic valve replacement (AVR) in patients without thromboembolic risk factors remains controversial. Treatment with warfarin is recommended for the first 3 months after biological AVR. The use of antiplatelet therapy - mainly aspirin (ASA) - is suggested as an alternative treatment but its efficacy is...
متن کاملComparison of dual antiplatelet therapy versus oral anticoagulation following transcatheter aortic valve replacement: A retrospective single-center registry analysis.
BACKGROUND The choice of optimal antithrombotic regimen after transcatheter aortic valve replace-ment (TAVR) remains a matter of debate. The objective of this study was to compare both efficacy and safety outcomes based on the type of antithrombotic therapy prescribed after TAVR Methods: This is a retrospective analysis of 514 consecutive patients treated with either dual antiplate¬let therapy ...
متن کاملSelf management of oral anticoagulant therapy after heart valve replacement.
OBJECTIVE Patients with mechanical heart valves require lifelong oral anticoagulant treatment which entails frequent blood sampling and dosage adjustment. The purpose of this study was to investigate the feasibility of letting heart valve operated patients manage blood specimen analysis and dosage adjustment themselves. METHODS A total of 21 patients were enrolled in the study and followed fo...
