Prosthetic heart valves and pregnancy.
To the Editor: Pregnant women with mechanical heart valves are an ultrahigh-risk group, in whom all anticoagulant options pose maternal and/or fetal risks. It is unclear why the authors of the recent update1 selected 4 studies, neither the most recent nor of the highest quality, to give a warfarin embryopathy rate of 1.6%. This anomaly rate is not supported by evidence in their Table 1 (3.9% of...
متن کاملThe heart endocardium is derived from vascular endothelial progenitors.
The embryonic heart is composed of two cell layers: the myocardium, which contributes to cardiac muscle tissue, and the endocardium, which covers the inner lumen of the heart. Whereas significant progress has been made toward elucidating the embryonic origins of the myocardium, the origins of the endocardium remain unclear. Here, we have identified an endocardium-forming field medial to the car...
متن کاملPreface: Heart valves.
Reference to this organ, which perhaps was not commonplace in the scientific literature 15 years ago, has become exceedingly prevalent in the past 5 years. The field of heart valve research has become contemporary due to a heightened awareness of the seriousness and frequency of heart valve disease. Indeed, valve therapies are still extremely limited for patients above the age of 75 or less tha...
متن کاملTissue-engineered heart valves.
Currently-used mechanical and biological heart valve prostheses have several disadvantages. Mechanical prostheses, based on carbon, metallic and polymeric components, require permanent anticoagulation treatment, and their usage often leads to adverse reactions, e.g. thromboembolic complications and endocarditis. Xenogenous and allogenous biological prostheses are associated with immune reaction...
متن کاملArtificial Heart Valves
The cardiovascular system is a closed circulatory system that ensures blood flow through the human body. Blood circulates through two systems; the first is responsible for pushing blood from the heart to the lungs to capture oxygen, and the second is responsible for distributing oxygenated blood to body organs. This system is composed of a double pump with branched tubes that leads blood from t...
