Valvular heart disease affects 30% of the new-borns with congenital heart disease. Valve replacement of semilunar valves by mechanical, bioprosthetic or do
However, homografts are of limited availability, they induce an immunologic response, the valves undergo degeneration limiting their durability and making reoperation necessary. In conclusion, for a selected group of patients homografts represent attractive alternatives to the implantation of mechanical or ...
Promising alternatives to currently available replacement heart valves are being developed using the basic principles of tissue engineering. Significant progress has been made in the development of a tissue-engineered heart valve substitute, including the characterization and development of various different ...
Although we were so sure our hospital stays were over, once the Afib came back just three weeks after the cardioversion two days after the valve replacement, it was unfortunately a matter of time. At the emergency room he was hooked up to IV’s once again, given stronger meds to steady ...
Detects abnormalities in the valves, myocardium , and pericardium Cardiac magnetic resonance imaging ( CMR ):[1,2,6,13,25] Characterizes the myocardium Can detect: Damaged myocardium Fibrosis Myocardial infarction (acute and chronic) Infiltrated and inflammatory disease Recommended if: Poor ac...
valves cease to perform adequately, it becomes necessary to provide a replacement prosthetic aortic valve. Heretofore, it has been proposed to implant generally smaller valves within the previously implanted degenerated heart valve. While such smaller valves can improve valve function, they frequently ...
Prosthetic valves When a woman who may become pregnant has a native valve replaced, the risks and benefits of a biological valve (risk of structural deterioration and less durability, with 90% likelihood of reintervention for valve replacement after 15 years,29 but with no need for anticoagulation...
1 Whereas valve replacement surgery has evolved since the early 1950s, when it was first described as an experimental procedure in dogs,2 major clinical advances in valve replacement constructs have lagged. There still exist only 2 basic alternatives, mechanical and biological prostheses, both of ...
State of the art replacement heart valves are less than ideal and are associated with significant complications. Using the basic principles of tissue engineering, promising alternatives to current replacement heart valves are being developed. Significant progress has been made in the development of a ...
The field of polymeric and tissue-engineered heart valves has long been a promising one. The known limitations of current bioprosthetic and mechanical valves have inspired extensive research with these alternatives, but the impressive science behind them remains at the level of the benchtop and animal...
