Methods: Nine different valves were tested in the aortic position of a model heart chamber in
the Edinburgh milk rig. These included caged-ball valves (Starr-Edwards silastic ball with …

The risk of embolism in patients with prosthetic valve replacements is determined by a
number of dif ferent factors. Mechanical prostheses are more thrombogenic than are …

Thromboembolism continues to be a major cause of morbidity and mortali-ty in patients who
have undergone insertion of a mechanical prosthesis for treatment of valvular heart disease …

Background: The aim of our study was to investigate the efficacy of the combination of
clopidogrel and aspirin in the prevention of thrombus formation on artificial heart valves in …

Increased inflammatory biomarkers have been reported in prosthetic heart valve thrombosis
(PHVT). Monocyte to HDL ratio (MHR) and albumin to CRP levels (CAR) are two biomarkers …

Our experience with thromboembolism in 283 patients surviving at least 1 week following
insertion of Starr-Edwards valves is reported here. Of these patients, 155 underwent aortic …

With the advent of cardiac valve replacement surgery, it has been possible to prolong life
and dramatically alleviate the hemodynamic symptoms of valvular heart disease in many …

Polymer heart valves have been under investigation since the 1960s, but their success has
been hampered by an overall lack of durability mainly due to calcification of the leaflets and …

Background: In this study, we investigated the clinical importance and possibility of mean
platelet volume to be a predictive marker for acute mechanical valve thrombosis. Methods …

Mechanical forces caused by the dynamics of blood flow in the region of porcine
bioprosthetic valves may directly injure the valve as well as formed elements of the blood …
