There is general acceptance of a causal connection between mitral valve prolapse and systemic embolic events. The precise mechanism, however, remains controversial, with current hypotheses favoring the embolization of thrombotic deposits from the abnormal mitral valve. It might be surmised that echocardiography could easily document the presence of such thrombi, ...

A prominent filling defect was depicted on a radionuclide ventriculogram in a patient with mitral regurgitation. This defect was later shown, by cardiac ultrasound, to be due to mitral valve prolapse into the left ventricle during diastole. This case illustrates that mitral valve prolapse should be added to the list ...

As etiologic factors for mitral valve prolapse, papillary muscle dysfunction due to coronary artery disease, hypertrophic obstructive cardiomyopathy, atrial septal defect and trauma have been reported. Connective tissue diseases such as Marfan's syndrome. Ehlers-Danlos syndrome or Turner's syndrome may also result in mitral valve prolapse. In the majority of patients ...
Matsuo T - - 1988
A 32-year-old man with distal skeletal manifestations of Marfan's syndrome had experienced shortness of breath and orthopnea for one month. Physical examination showed the presence of severe aortic regurgitation. Both noninvasive and invasive studies revealed that the aortic regurgitation was induced by previously undescribed peculiar and unusual etiology: diastolic prolapse ...
Rueda B - - 1988
Incorporating prognostically related auscultatory, M-mode, 2DE and recent Doppler echocardiographic features, the following strict criteria for establishing the diagnosis of mitral valve prolapse (MVP) have been advanced: 1. auscultatory; mid-to-late systolic clicks and a late systolic murmur at the apex or mid-to-late systolic clicks at the apex which move appropriately ...

To assess the clinical significance of the echocardiographic degree of mitral valve prolapse, we prospectively evaluated with Doppler echocardiography 245 consecutive patients referred with signs or symptoms consistent with a diagnosis of mitral valve prolapse. The echocardiographic degree of mitral valve prolapse was measured by a scoring system that incorporates ...
Leong K H - - 1988
Mitral valve prolapse is one of the more common cardiac conditions in our community. The prevalence is difficult to assess due to differences in diagnostic criteria and population selection. The prevalence in the community has been estimated to be from 5 to 15%. In females there is a decline in ...
Lembo N J - - 1988
It is known that rheumatic heart disease frequently results in isolated mitral regurgitation without concomitant mitral stenosis, especially in countries with a high prevalence of rheumatic fever. However, more recent surgical pathologic data also have demonstrated a high incidence of mitral valve prolapse in cases of rheumatic heart disease, which ...
Seelenfreund M H - - 1988
Mitral valve prolapse (M.V.P.) is a noninflammatory degeneration of the mitral valve leaflets which results in a billowing of the redundant valve tissue toward the left atrium during the systolic phase. Mitral valve prolapse can be diagnosed by echocardiography or by auscultation where a characteristic mid-systolic click and late systolic ...

High-frequency coagulation is used with advantage for a number of purposes, including the production of haemostasis during surgery. The morphological changes which thermocoagulation produces in or near the wall of an artery remain, however, largely unknown; and systematic research in the subject is long overdue. As might be expected from ...
Kajino Y - - 1987
An eight-year-old girl with mitral regurgitation in acute rheumatic fever was examined by echocardiography. The examination showed posterior displacement of the coaptation point of the anterior mitral leaflet, i.e. anterior mitral prolapse, and did not indicate signs of edematous change or verrucous fibrin deposits on the valves. Mitral valve prolapse ...

To analyze the behavior of aortic valve gradient (AVG) after ventricular extrasystole (VE), we studied 36 pure valvular aortic stenoses (AS) free of coronary artery disease and obstructive hypertrophic cardiomyopathy, in whom basal (B) (74 +/- 32 mm Hg) and catheter-induced post-VE (110 +/- 50 mm Hg) AVG were obtained. ...
Holgado G M - - 1987
Mitral valve prolapse was found in one of 133 patients with hypertension (0.75 percent) studied by two-dimensional echocardiography. This rarity may be related to the presence of hypertrophied papillary muscles that probably pull the chordae tendinae and mitral valve leaflets away from the left atrium in systole, thus preventing their ...

The spectrum of recognized cardiac lesions underlying infective endocarditis has been changing as a result of the decline in incidence of rheumatic heart disease, the recognition of the entity of mitral valve prolapse, and the improvement in cardiac diagnostic techniques. Sixty-three cases of native valve endocarditis diagnosed in Memphis hospitals ...
Virmani R - - 1987
Although the morphology of mitral valve prolapse (MVP) has been described, abnormalities of chordal arrangement and insertion have not been emphasized. We retrospectively reviewed 23 surgically-excised MVP and 10 control mitral valves removed at necropsy. Two-dimensional echocardiograms (2DE) were available in 10 MVP and in six additional controls. 2DE accurately ...
Levine R A - - 1987
The geometric or anatomic diagnosis of mitral valve prolapse, as opposed to the pathologic diagnosis of myxomatous valve disease, is based on the relationship of the mitral leaflets to the surrounding anulus. Current echocardiographic criteria for this diagnosis include leaflet displacement above the annular hinge points in any two-dimensional view; ...

Autonomic nervous system dysfunction has recently been identified in a subset of patients with mitral valve prolapse. These autonomic nervous system abnormalities may correspond, in part, to biochemical alterations in beta-adrenergic receptors. Nine women with mitral valve prolapse and symptoms and signs of beta-adrenergic hypersensitivity and seven normal volunteer women ...
Noah M S - - 1987
Two-hundred-and-thirty-two Saudi young women were prospectively clinically examined for the presence of mitral valve prolapse. Phonocardiograms recorded in all subjects at rest in supine position revealed 10.7% incidence of systolic clicks and/or mid to late systolic murmurs. Echocardiographic studies were performed in supine, left lateral as well as sitting up ...
Raichlen J S - - 1987
Tricuspid valve prolapse is an infrequent echocardiographic finding that is most commonly associated with mitral valve prolapse. When compared with patients exhibiting isolated prolapse of the mitral valve, patients with tricuspid valve prolapse are somewhat older individuals with a slightly higher frequency of neurologic symptoms, fatigue, weakness, supraventricular arrhythmias (especially ...
Saadah M A - - 1986
A healthy 28 year old housewife presented with sudden right hemiplegia and aphasia. No predisposing factors could be ascertained apart from posterior cusp mitral value prolapse on two dimensional echocardiography. Extensive investigations confirmed the presence of cerebral infarction and persistent occlusion of the left internal carotid artery near its origin.
Lewis B S - - 1986
The abnormal ECG T wave changes associated with mitral valve prolapse (MVP) were studied and quantitated in a group of 36 asymptomatic individuals with MVP and compared with a 27-member control group. The mean frontal plane T wave axis shifted markedly leftward on standing, with T wave axis less than ...

The authors report the prevalence of mitral valve prolapse in bipolar affective disorder. 22 bipolar patients (13 men and 9 women; age 17-75 years, mean 42.3) were selected at random from 41 bipolar patients for echocardiographic examination. Diagnosis of mitral valve prolapse was made if prolapsus of the anterior or ...
Ghosh P K - - 1986
Severe aortic regurgitation developed in three patients after aortic valve replacement within six months due to long sutures prolapsing across the "annulus" of Björk-Shiley prosthesis. At reoperation the offending sutures were trimmed or tucked back to the aortic wall to eliminate aortic regurgitation. Prolapse of unravelled knots may be the ...
Devereux R B - - 1986
To determine factors influencing the strength of association between mitral valve prolapse and mitral regurgitation, ruptured chordae tendineae, and infective endocarditis, the prevalence of mitral prolapse in patients with disease was compared with both clinical and population control groups. The prevalence of mitral valve prolapse was 4 percent among population ...
Spears P F - - 1986
The origin of chest discomfort in patients with mitral valve prolapse is controversial. We performed esophageal manometry in 18 patients with mitral valve prolapse, chest pain, and no significant coronary artery disease at cardiac catheterization. Fourteen of the 18 had esophageal disorders: five had diffuse esophageal spasm and two had ...
Devereux R B - - 1986
Mitral valve prolapse, the most common inherited cardiovascular condition, has been associated with a variety of signs, symptoms and electrocardiographic abnormalities, but the true spectrum of the mitral prolapse syndrome remains in doubt because clinical findings often contribute to patient identification and their prevalence in patient groups may be overstated ...
Fitzsimons P J - - 1986
We report three patients in whom hydronephrosis was diagnosed by ultrasonography in utero. In two fetuses, ureteroceles were detected prenatally and these proved to be the cause of obstruction. In the third, bilateral simple ureteroceles were discovered immediately after birth. In the last patient, failure to see ureteroceles in utero ...
Busch E H - - 1986
A case of angiographically-documented embolism is presented in a patient using oral contraceptives (OC) with marked mitral valve prolapse (MVP) and an atrial thrombus. OC use has been shown to decrease levels of antithrombin III and increase platelet coagulant activity. This increased coagulability may increase the risk of intra-atrial thrombus ...
Alpert M A - - 1986
To assess inter- and intraobserver variation in the echocardiographic diagnosis of mitral valve prolapse, three independent observers analyzed M-mode echocardiograms (n = 80) and two-dimensional echocardiograms (n = 65) of patients with a mobile midsystolic click with or without a late or holosystolic murmur. In addition, a control group of ...
Perloff J K - - 1986
Because the term mitral valve prolapse has pathologic connotations, considerable effort has been expended to establish acceptable diagnostic standards, but without general agreement. This report combines information from the history, physical examination, electrocardiogram, chest x-ray and 2-dimensional echocardiogram in an effort to avoid the artifice of using the 2-dimensional echocardiogram ...
Siegel-Sadewitz V L - - 1986
Variability of velopharyngeal valving between subjects has been a well established fact since the advent of new techniques for the direct viewing of the velopharyngeal sphincter during speech. Multi-view videofluoroscopy and nasopharyngoscopy have shown that there is variable contribution to velopharyngeal closure from the velum, the lateral pharyngeal walls, and ...

We searched for mitral valve prolapse in patients with spontaneous pneumothorax to test the hypothesis that both may be part of a common disorder of connective tissue. Echocardiographic mitral valve prolapse was found in 11 (50 percent) of 22 patients who had suffered spontaneous pneumothorax compared to four (10 percent) ...
Elam M B - - 1986
We examined a group of former oral contraceptive (OC) users, who had experienced cerebrovascular insufficiency, for the presence of hypercoagulable states. We found hypercoagulability in this group in the form of decreased plasma antithrombin III activity, increased platelet coagulant activity, and elevated plasma beta-thromboglobulin level. Certain characteristics (cigarette smoking, vascular ...
