Kopka, Stacy L., Laura C. Geran, and Alan C. Spector. Functional status of the regenerated chorda tympani nerve as assessed in a salt taste discrimination task. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R720–R731, 2000.—We tested whether the recovered ability of rats to discriminate NaCl from KCl after chorda tympani nerve transection (CTX) is causally linked to nerve regenerat...

background: primary intra cardiac tumors are rare. in this article, we present papillary fibroelastoma of mitral valve chordae. case presentation: a 35-year old man presented with atypical chest pain and palpitation. physical examination and electrocardiogram were normal. transesophageal echocardiography (tee) revealed a mass of 1015 mm attached to chordae of anteromedial papillary muscle of m...

In animal models, severing the chordae tendineae of the mitral valve reduces the maximum global left ventricular elastance (Emax,g), a load-independent measure of left ventricular systolic performance; moreover, chamber geometry is altered with systolic bulging in the region of the papillary muscle insertions. This suggests that forces transmitted by the mitral apparatus increase the regional v...

OBJECTIVE The papillary muscles and the chordae tendineae of both mitral leaflets contribute to the preservation of the left ventricular function. Most surgeons, however, routinely excise the anterior mitral leaflet. METHODS In a group of nine patients, six of them underwent mitral valve replacement alone and three underwent both aortic and mitral valve replacements, all the mitral apparatus ...

Although mitral valve repair (MVR)—for mitral regurgitation (MR) secondary to chronic valvular heart disease (CVHD)— is becoming more common in veterinary medicine, there is little information about the morphology of the mitral valve apparatus that is used to guide veterinary surgeons. Therefore, we investigated the locations of MR using echocardiography in 12 client-owned dogs with MR. Nine (7...

Sixty-two consecutive surgically removed chronic rheumatic mitral valves were classified and tabulated according to their pathological features in relation to age and sex of the patients. The pathological features of the valves are quite different from the cases seen in Western hemisphere. Three types of gross pathological features are described. First is fibrous stenotic type which has very th...

Fifty-three specimens in which the primary diagnosis in life was coaretation of the aorta were examined; only nine had a mitral valve of normal size and configuration. Ten specimens had a normally formed valve mechanism which was small in comparison to both tricuspid valve and left ventricle. Three other specimens had a normally formed but small valve which exhibited a short free margin of the ...

The Purkinje fibers of the rabbit false tendons (chordae tendineae spuriae) are endocrine cells containing immunoreactive atrial natriuretic factor (ANF) and ANF messenger RNA (mRNA). These cells, as visualized by immunocryoultramicrotomy, contain immunoreactive ANF in their secretory granules and their Golgi complex and exhibit ANF mRNA, as visualized by in situ hybridization with an ANF compl...
