چکیده
La presencia de cuerdas tendinosas accesorias de la válvula mitral son un hallazgo poco frecuente y resulta aún más raro la presencia de cuerdas tendinosas accesorias a nivel de la aurícula izquierda. Estas bandas de tejido accesorio habitualmente unen la cara auricular de la valva mitral anterior con el septum interauricular o el techo de la aurícula izquierda. Los casos reportados se han asociado a insuficiencia mitral importante por prolapso de la valva anterior generada por la tracción ejercida por la cuerda auricular izquierda accesoria. Usualmente no son diagnosticadas con el ecocardiograma y por el contrario son un hallazgo intraoperatorio. Presentamos el caso de una paciente de 10 años que acude a nuestro centro por cuadro clínico de un año de evolución, caracterizado por deterioro progresivo de la

Testicular torsion in Henoch--Schonlein syndrome.
Harvey (1968) used the term "wreck.ing ball" to describe the movements of a calcified pedunculated right atrial myxoma, likening it to the swinging iron ball suspended from a crane used for demolishing buildings. In the patient he described the tricuspid valve had been almost completely destroyed by the movemen,ts of the tumour. Similar patients with incompetent tricuspid valves damaged by calc...
متن کاملThe value of left parasternal impulse recordings in the assessment of mitral regurgitation.
Left parasternal cardiograms were recorded at the fifth intercostal space in 30 patients with mitral regurgitation. Early systolic outward movements (E), late systolic outward movements (LOM), and the ratio of the LOM area to the total area occupied by the left parasternal cardiogram (LPC area) were examined. Thirteen patients had pure mitral regurgitation due to ruptured chordae tendineae (ten...
متن کاملA Rare Morphological Variant Accessory Posterolateral Cusp of Mitral Valve with Accessory Papillary Muscle in Left Ventricle in An Adult Cadaver in Middle East-A Case Report
Various cases of accessory leaflets of mitral valve or tissue around the opening have been reported in the past. In some cases they were the main etiological factor for sub aortic stenosis or regurgitation. Here we report a rare finding of accessory posterolateral cusp of mitral valve with accessory papillary muscle in left ventricle of an adult male cadaver. Such variation has not been reporte...
متن کاملMotion of the interatrial septum in acute mitral regurgitation. Clinical and experimental echocardiographic studies.
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...
متن کاملEchocardiographic Diagnosis of Mitral Regurgitation due to Ruptured
The echocardiographic findings from six patients with ruptured chordae tendineae from the posterial mitral valve leaflet and three with ruptured chordae from the anterior leaflet are reported; in all cases the diagnosis was later proven by openheart surgery. The constellation of echocardiographic findings suggesting iruptured chordae tendineae to the posterior leaflet are: (1) The appearance of...
