In a 14-month period mitral leaflet prolapse was diagnosed in 85 patients by echocardiography or cineangiography. Chest pain alone was the presenting complaint in 30 patients and linked with palpitation, dyspnoea, or syncope in 9. Eleven presented with major neurological disturbances (9 had transient ischaemic attacks), 10 with palpitation, 4 ...

A patient with the prolapsing mitral valve syndrome demonstrated a most striking early diastolic sound. Noninvasive study with phonocardiograms, external pulse recordings, and echocardiograms lead us to believe that the sound may be related to the initial opening movement of the mitral valve. To our knowledge, such a mechanism for ...

The clinical, echocardiographic, and catheterization findings in a patient with discrete subaortic stenosis, aneurysm of the membranous interventricular septum, and mitral valve prolapse are presented. Echocardiography showed a subaortic membrane, abnormal aortic valve motion, accentuated systolic anterior motion of the membranous interventricular septum, and prolapsing mitral leaflets. Cardiac catheterization confirmed ...

Ten per cent of all patients referred to the echocardiography laboratory for diagnostic evaluation had mitral valve prolapse. Of these 35 patients, 19 (54 per cent) had prolapse of both the anterior and posterior mitral leaflets. Of the 19 patients, 13 had Type A or midsystolic prolapse, whereas six had ...

"Sphygmo-Recording," a non-invasive method for timing the arterial pulse wave contour provides an objective measure of responses to medication in patients with hyper- and hypothyroidism. The QKd interval, i.e., the interval from the onset of the QRS complex (Q) to the onset of the Korotkoff sounds (K) at the brachial ...

Mitral valve prolapse is a condition that is being recognized with increased frequency. It is not known whether its incidence is increasing, or whether we are better able to diagnose it today. In the idiopathic or familial variety, the mitral valve pathology is almost always that of myxomatous degeneration. Some ...

Mitral valve motion, left ventricular segmental contraction and severity of arterial stenosis were analyzed in 92 patients with coronary artery disease and 28 patients with "atypical chest pain" and normal coronary arterio-rams. Mitral valve motion was evaluated for the presence or absence of leaflet prolapse. Segmental contraction was evaluated by ...

Two patients with a prolapse and cleft posterior mitral leaflet were studied. The first case had an associated ostium secundum type atrial septal defect. In both cases, the pansystolic regurgitation of contrast material during angiography corresponded to the pansystolic configuration of the murmur. In each instance, the systolic murmurs displayed ...

The echocardiograms of seven patients with large pericardial effusions were found to show posterior motion of the mitral leaflets in systole as seen in prolapse of the mitral valve. Repeat echocardiograms after resolution of the effusion revealed normal mitral valve motion. None of the patients had clinical evidence of prolapsed ...
Weiss A N - - 1975
An important potential source of error in the echocardiographic diagnosis of mitral valve prolapse has been identified -- namely a systolic hammock-like pattern of the anterior and/or posterior mitral leaflet echoes, similar to that associated with true mitral valve prolapse, produced artifactually when the ultrasonic transducer is angulated inferiorly. Utilizing ...

Of 184 patients with acute rheumatic fever and associated mitral insufficiency encountered during a 15 year period, 34 manifested a mid-late systolic murmur or a nonejection click, or both, during the course of follow-up. The mid-late systolic murmur later disappeared in four patients whose condition is now considered normal. In ...

Ultrasound has become an important diagnostic tool for a variety of cardiac problems. It has the advantage of being noninvasive and, in certain conditions, quite accurate. It has been used for the assessment of mitral stenosis and for the diagnosis of cardiac tumors, mitral valve prolapse, asymmetric thickening of the ...
Fallen, Ernest L.
The presence of an isolated midsystolic click and/or late systolic murmur in an otherwise healthy young individual is a totally benign entity and represents a normal variation of mitral valve motion and function. There exists a very small subset of patients with mitral prolapse easily identified by certain clinical characteristics, ...
Rosser, Walter W.
The author discusses the pathophysiology of mitral valve prolapse and provides guidelines to identify and treat low-to high-risk mitral valve prolapse. An approach to diagnosing bacterial endocarditis and its prophylaxis are also discussed. The author reviews mitral valve prolapse syndrome and the risk of sudden death.

An examination has been made of the efficiency of the gravimetric reagent hexamethylenetetramine in the separation of thorium from rare earths and in the determination of thorium. Losses to the filtrate, beaker and filter paper are evaluated as well as the extent of rare earth and other contamination of the ...
