BACKGROUND The contribution of anterior mitral leaflet second-order ("strut") chordae tendineae to left ventricular (LV) systolic mechanics is debated; we measured the in vivo contribution of anterior chordae tendineae (ACT) and posterior chordae tendineae (PCT) to regional and global LV contractile function. METHODS AND RESULTS Eight sheep had radiopaque markers implanted in the LV epicardiu...
Study was made on 16 human embryos at developmental stages 13-15 (fifth week). The facial nerve was traced on serial sections made in three planes (sagittal, frontal and horizontal) and stained with routine histological methods and impregnated with silver. In embryos at stage 13 the facial ganglion forms a complex structure with the vestibulocochlear ganglion. It is of fusiform shape in contact...
The VIIth cranial (facial) nerve is largely motor in function (some sensory fibres from external acoustic meatus, fibres controlling salivation and taste fibres from the anterior tongue in the chorda tympani branch). It also supplies the stapedius (so a complete nerve lesion will alter auditory acuity on the affected side). From the facial nerve nucleus in the brainstem, fibres loop around the ...
The interatrial septal echocardiograms from 15 patients with acute mitral regurgitation due to ruptured chordae tendineae were compared with those from 14 normal subjects. On the cross-sectional echocardiogram, the interatrial septal configuration in patients with chordal rupture showed a characteristic pattern in which the interatrial septum (IAS) was flat or slightly convex toward the left at...
Ruptured chordae of the tricuspid valve. The consequence of flow-directed Swan-Ganz catheterization.
A case of autopsy-documented ruptured chordae tendineae of the tricuspid valve, secondary to flow-directed Swan-Ganz catheterization of the right side of the heart is presented. A possible mechanism is discussed and safeguards to prevent this complication are suggested.
