The mode and extent of the regressions of heart valves, valvular rings, and tendon chords, as well as the size of atria and ventricles in 316 hearts of different age groups (macroscopically normal at autopsy), were studied. With increasing age, the valves showed marked thickening and loss of...
A locking component (815) and a tension member (820) wherein the anchoring component is enabled to be positioned on a first target site of a tissue component and the locking component (815) is enabled to be positioned on a second target site of a tissue component of the heart, and the...
Mid-term outcomes in aortic stenosis patients treated with contemporary balloon expandable and self-expanding valves; does valve size have an impact on out... PURPOSE. Aim of the study was the head-to-head comparison of these transcatheter heart valves (THV) with emphasis on patients with small...

Conclusion: We conclude that despite undeniable recent improvements in the design of artificial heart valves, 19 mm aortic prostheses continue to create significant obstruction of the left ventricular outflow tract and, possibly as a consequence of this, fail to bring about significant reduction in ...
A couple of years ago, an echocardiogram showed a small leak in my mitral valve. A year later, a follow-up test showed some leakage in my tricuspid valve. The valves aren't caus... Lee R. R Lee - 《Harvard Heart Letter from Harvard Medical School》 被引量: 0发表: 2009年...
