1. New frontiers in the pathology and therapy of heart valve disease: 2006 Society for Cardiovascular Pathology, Distinguished Achievement Award Lecture, United States-Canadian Academy of Pathology, Atlanta, GA, February 12, 2006.
Match Strength: 12.037
This review summarizes several areas relative to the pathology of heart valve disease in which there has been rapid and ongoing evolution, namely, our understanding of: (a) the dynamic functional biology of cardiac valves; and (b) the pathology/pathobiology of valvular heart diseases; (c) new developments in valve repair and substitution using percutaneous approaches; and (d) progress toward the exciting potential of therapeutic valvular tissue engineering and regeneration, including the challenges that will need to be overcome before such therapeutic advances can become clinically useful. ...

2. Pathology of infectious and inflammatory diseases in prosthetic heart valves.
Match Strength: 10.450
Prosthetic heart valves, both mechanical and biological (xenograft valves, stented or unstented), show an inflammatory reaction (infective endocarditis), associated predominantly with bacterial/fungal infection. Somewhat surprisingly, no immune-mediated reaction has been reported thus far. This may, among other reasons, be related to the fact that the tissues are "fixed" with aldehydes and are virtually isolated from host circulation, separated by synthetic material (the valve stent and the fabric covering it). Stentless valves (especially these without fabric covering them), however, have no ... Read More »

3. Chondromodulin-I maintains cardiac valvular function by preventing angiogenesis.
Match Strength: 6.272
The avascularity of cardiac valves is abrogated in several valvular heart diseases (VHDs). This study investigated the molecular mechanisms underlying valvular avascularity and its correlation with VHD. Chondromodulin-I, an antiangiogenic factor isolated from cartilage, is abundantly expressed in cardiac valves. Gene targeting of chondromodulin-I resulted in enhanced Vegf-A expression, angiogenesis, lipid deposition and calcification in the cardiac valves of aged mice. Echocardiography showed aortic valve thickening, calcification and turbulent flow, indicative of early changes in aortic ... Read More »

4. Cardiac imaging in rheumatic diseases.
Match Strength: 5.421
The majority of the imaging techniques in cardiology could be applied in rheumatic diseases (RDs), such as echocardiography, single-photon emission computed tomography (SPECT), radionuclide ventriculography, angiography, cardiovascular MRI and CT. Inflammatory pericardial involvement is the most common cardiac manifestation in various forms of RD. Echocardiography is the gold standard for diagnosis of pericardial abnormalities, demonstrating location and amount of pericardial effusion. Cardiac MRI and CT can be used to assess the features of pericardial effusions and peracardial structures. In ... Read More »
