Clinical features and investigative findings in presence of mitral leaflet prolapse. Study of 85 consecutive patients.

摘要: In a 14-month period mitral leaflet prolapse was diagnosed in 85 patients by echocardiography or cineangiography. Chest pain alone the presenting complaint 30 and linked with palpitation, dyspnoea, syncope 9. Eleven presented major neurological disturbances (9 had transient ischaemic attacks), 10 4 undue persistent fatigue, 2 dizziness. Seventeen were referred not because of symptoms but clicks murmurs. Overall, chest affected 61 unless associated coronary artery disease anginal. Palpitation admitted 42 patients; dizziness, lightheadedness, paraesthesiae 15, 12. Systolic auscultatory abnormalities noted 69: 25 single clicks, 3 multiple 19 both click(s) murmur, 22 murmur alone. Electrocardiography revealed ST segments flat for greater than 0-10 s 21, prolonged QTc 18, T wave flattening inversion inferior limb lateral leads 14. The exercise stress test abnormal 13 27 patients. Mitral valve echograms showed definite 61, 'possible' 14, normal 8 angiographic proof prolapse. Cardiac catheterization left ventriculography posterior 36, leaflets 2, ventricular wall motion 16 cases. Selective arteriography 31 cases vessel narrowing larger equal to 80 per cent lumen diameter 4, all angina. This consecutive series indicates that physical event is more common hitherto appreciated, priminently non-anginal pain, disturbances, 90 could be shown echocardiographically.
