Retrograde prolapse of the ileocecal valve results when redundant mucosa produces prominent lips of the ileocecal valve. The prominent valve produces a filling defect within the cecum. With manual palpation or hydrostatic pressure of the barium column, this prominent ileocecal valve then prolapses in a retrograde fashion to produce a ...

It is extremely helpful for the examiner to separate murmurs of nonorganic origin into one of two categories. The innocent heart murmur group defines five specific entities: the pulmonary systolic murmur, the vibratory systolic murmur, the supraclavicular systolic murmur, the mammary souffle, and the venous hum. All other nonorganic murmurs ...

Electrocardiographic mimicry necessitates differentiation between acute pericarditis and early repolarization. Among 96 persons, limb-lead RST deviations occurred in all 48 with pericarditis, but only 27 with early repolarization. RS-T vectors (A RS-T) in pericarditis tended to be horizontal (25 patients) and left of the T vector, A T (28 patients); ...
Nanda N C - - 1976
Nine adult patients with large pericardial effusions (PE) demonstrated echocardiographic motion abnormalites of cardiac valves in systole. In four cases (Group 1), the abnormal findings consisted of prominent systolic anterior movements of the mitral valve resembling those seen in idiopathic hypertrophic subaortic stenosis. In Group 2(five cases), typical mitral valve ...

This paper is a critical evaluation of the nature and meaning of various radical changes in sexual customs and behavior and their clinical consequences. The author contends that many of the revolutional changes demonstrate a complete and disastrous disregard of knowledge gained through painstaking psychodynamic and psychoanalytic investigations over the ...
Winters S J - - 1976
When a patient with mitral valve prolapse was found to have myotonic dystrophy, his family was studied to ascertain the occurrence of these abnormalities. Of 25 relatives screened, 8 had evidence of both myotonic dystrophy and mitral valve prolapse and 2 had evidence of myotonic dystrophy alone. Thirteen patients had ...

Renal reabsorption of bicarbonate was studied in Merino ewes during carbonic anhydrase inhibition. Bicarbonate reabsorption was directly proportional to plasma bicarbonate concentration. No tubular maximum for bicarbonate was demonstrated. Elevation of arterial PCO2 or depression of arterial pH caused slight increases in bicarbonate reabsorption. The data suggest that bicarbonate is ...

The cross-sectional echocardiographic features of mitral valve prolapse were defined in 26 children (ages 2-18 years) using a real-time, multiple-crystal ultrasound scanner. In each patient the physical findings of the mitral valve click-murmur syndrome were present and mitral valve prolapse had been diagnosed previously by conventional single crystal echocardiography. Mitral ...

The midsystolic click-late systolic murmur syndrome is a complex entity with variable manifestations that involves a primary process causing myxomatous degeneration of the mitral valve leaflet(s) and subsequent systolic mitral valve leaflet prolapse. Other cardiac diseases may cause mitral valve prolapse and regurgitation associated with a midsystolic click that mimics ...

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 ...
Caudill C C - - 1976
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 ...
Cohen M V - - 1976
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 ...

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 ...
Levisman J A - - 1976
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 ...

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.
