Study Finds Potential Problem in Heart Valve ImplantsDoctors have discovered a potential problem involving implantedheart valves that hundreds of...Marchione, Marilynn
Further, a fundamental problem inherent to the use of existing mechanical and biological prostheses in the pediatric population is their failure to grow, repair, and remodel. It is believed that a tissue engineered heart valve can accommodate many of these requirements, especially those pertaining to...
Calcification Assessment of Bioprosthetic Heart Valve Tissues Using an Improved In Vitro Model Calcification is a recurrent problem in patients suffering from heart valve disease and it is the main cause of failure in biological heart valve prosthese... CC D'Alessandro,MA Komninou,AF Badria,... ...
In this type, there’s nothing wrong with your mitral valve, but a problem elsewhere in your heart prevents it from functioning properly. Heart failure and arrhythmias, for example, can cause secondary mitral valve regurgitation. Both types of mitral valve regurgitation can be either acute (develo...
A heart murmur is not always a sign that something is wrong, but it is often one of the first signs of trouble if you do have a problem with your aortic valve. You may not notice any symptoms, but some people with aortic valve disease experience problems like: Chest pain — a feeling...
Heart murmurs Normally, blood flows from one heart chamber to another, passing through little doors called valves that open and close. But, if there is a problem with one of the valves, blood flow becomes turbulent, causing a whooshing or raspy sound called amurmur. ...
PROBLEM TO BE SOLVED: To provide an artificial heart valve device which lessens the danger of thrombus formation, removes the stagnating region of blood, assures the laminar flow of the blood and allows the good washing of all the valves. ;SOLUTION: This artificial heart valve device includes ...
In particular, a pressure medium control valve for controlling the flow direction in the pressure medium circuit, and a piston pump for pumping the pressur... PROBLEM TO BE SOLVED: To provide a piston pump (60) for controlling a once-through direction in a pressure medium circuit, and partic...
Prosthetic heart valve replacement is currently performed with acceptable low mortality. However, complications and morbidity related to the use of different valve substitutes, both biologic and mechanical, remain a substantial problem (1). S Gabbay,JY Kresh - Springer New York 被引量: 3发表: 1985...
