Mitral valve myxoma is a very rare entity. Multiple myxomas with extensive involvement of the anterior and posterior leaflets of the mitral valve are exceedingly rare. We report a 58-year-old man who was admitted as sudden syncope. Thoracic echocardiography showed several masses adherent to the anterior and posterior leaflets and the mitral annulus with obvious mobility. Intraoperative probing ...

We present new algorithms to compute patient specific strain maps for mitral valve leaflets, by tracking and modeling deformations of the mitral valve apparatus in 3D echocardiography. We can then quantify comparisons of mitral leaflets strain maps between normal patients and cases of mitral valve prolapse or regurgitation. For patients with mitral valve regurgitation, we compare mitral leaflet...

The essence of the Ebstein's malformation is that the tricuspid valve leaflets do not attach normally to the valve annulus, and the effective orifice is displaced downward into the right ventricular cavity at the junction of the inlet and trabecular components of the right ventricle. Only the septal and posterior leaflets are displaced and divide the right ventricle into two portions. The inlet...

OBJECTIVE The aim of the present study was to define a method to pre-determine the correct size of neo-sinuses of Valsalva in the reimplantation type of valve-sparing aortic operation. METHODS The objective was achieved in three steps: (1) evaluation in the healthy population, of the normal size of sinuses of Valsalva expressed as the area surrounding fully opened aortic cusps, the so-called ...

Euterpe oleracea (açaí) is a palm tree well known for the high antioxidant activity of its berries used as dietary supplements. Little is known about the biological activity and the composition of its vegetative organs. The objective of this study was to investigate the antioxidant activity of root and leaflet extracts of Euterpe oleracea (E. oleracea) and characterize their phytochemicals. E. ...

OBJECTIVE To assess the effect of leaflets on promoting informed choice in women using maternity services. DESIGN Cluster trial, with maternity units randomised to use leaflets (intervention units) or offer usual care (control units). Data collected through postal questionnaires. SETTING 13 maternity units in Wales. PARTICIPANTS Four separate samples of women using maternity services. Ant...

In a patient with severe tricuspid regurgitation and mild pulmonary stenosis due to carcinoid heart disease cross sectional echocardiography showed nodular thickening and coaptation of the tricuspid leaflets at the beginning of systole. The leaflets were, however, seen to be increasingly pulled apart as right ventricular systole proceeded. This finding, which is probably due to traction on the ...
