Clinical and echocardiographic characteristic of mitral valve chordae rupture. 1985

I Tomov, and M D Todorova, and R Shabani

In 23 patients with mitral valve chordae rupture, the diagnostic sensitivity, specificity and predictive accuracy of various changes found by one-dimensional echocardiography (M-echo) were determined. Nearly all M-echo changes have a relatively low sensitivity (10-50%), high specificity (80-100%) and moderate predictive accuracy (30-80%). Greater diagnostic value--moderate sensitivity, high specificity and greater predictive accuracy--is shown by the following changes: systolic mitral valve flutter, diastolic mitral leaflets flutter, paradoxical (chaotic) movement of the posterior mitral leaflet in diastole. Of very low sensitivity (10%) but high specificity (100%) are pathological systolic echo-signals in the left atrial cavity.

D008944	Mitral Valve Insufficiency	Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.

D008945	Mitral Valve Prolapse	Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

D008946	Mitral Valve Stenosis	Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.

D010701	Phonocardiography	Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine.	Phonocardiographies
D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
D002815	Chordae Tendineae	The tendinous cords that connect each cusp of the two atrioventricular HEART VALVES to appropriate PAPILLARY MUSCLES in the HEART VENTRICLES, preventing the valves from reversing themselves when the ventricles contract.	Tendineae, Chordae
