53-year-old man, who had undergone dental treatment 2 months prior, presented with a slight fever and generalized weakness for several weeks. He was examined carefully in a regional hospital. There was no elevation of inflammatory markers, and his blood culture was negative. Electrocardiogram showed atrial fibrillation. Transthoracic and transesophageal echocardiography (TEE) demonstrated a lar...

A2-year-old cachectic cross-breed gelding was admitted toVeterinary Teaching Hospital of University of Tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. Clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. Therespiratory and heart rates were 35/min and 60 bpm, respectively.Agrade III/IV pansystolic murmur...

Echocardiography detected a mobile left ventricular tumour. The tracing showed a cluster of echoes in the left ventricular outflow tract corresponding to the location of the tumour as confirmed by cineangiograms. At operation, a thrombus was discovered, attached to a chorda tendineae.

The case was a Japanese man of 62 years old. A bulbar mass attached to mitral valve anterior leaflet was discovered in an echocardiography within detailed examination of ischemic heart disease accidentally. We diagnosed him as ischemic heart disease and doubt of heart tumor. We thought about the danger of future embolism, surgical treatment was decided. We dissected the tumor together with one ...

Mitral valves, including the papillary muscles, were harvested from freshly slaughtered sheep and implanted in 10 recipient growing sheep. A strip of ovine pericardium was used to reinforce the anulus and a patch of expanded polytetrafluoroethylene was used to cover the donor papillary muscle. In four valves the natural chordae tendineae at the anterior cusp were supported by two pairs of 5-0 e...

In the left ventriculogram in the right anterior oblique projection the plane of the mitral valve is seen in profile and the papillary muscle shadows are outlined. The distance from the middle of the papillary muscles to the plane of the mitral valve during systole was used to assess the average length of the chordae tendineae, and the area of the papillary muscle shadows was measured as an ind...

BACKGROUND We set out to evaluate mitral valve repair with the loop technique under dynamic conditions, using a U-Clip to anchor the loop unit to a papillary muscle. METHODS Mitral valve prolapse was artificially developed by resecting 4 chordae tendineae of a resected porcine heart. The loop unit was anchored to the papillary muscle using U-Clips. Each chordal loop was fixed on the prolapsed...

The left side of the tongue of the Mongolian gerbil, Meriones unguiculatus, was experimentally innervated with both chorda tympani nerves. While this dual innervation did not increase the number or volume of fungiform taste buds on the left side, at least half of the taste buds were dually innervated since they could be neurotrophically maintained by either chorda tympani nerve. Impulse dischar...

Echocardiographic diagnosis of rupture of the chordae tendineae to the anterior and posterior leaflets of the mitral valve may be difficult to make. Two patients, one with rupture of chordae tendineae to the posterior leaflet and the other with rupture of chordae tendineae to the anterior leaflet of the mitral valve, are reported to illustrate the use of an exploratory "continuous scanning" tec...
