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 ...

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 ...

The association of joint laxity and mitral valve prolapse (MVP) has been disputed. In this study of an Arab population, the joint mobility scores of 29 subjects with MVP, 10 of whom were asymptomatic, were compared to 60 normal controls. It was found that the joint mobility score was significantly ...

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 ...

In this study we reevaluated whether the sole cause of mitral valve prolapse (MVP) and aortic valve prolapse (AVP) is myxomatous degeneration. Forty-two surgical cases of prolapsed valves with mitral and/or aortic regurgitation were reviewed (AVP in nine, MVP in 27, and combined AVP and MVP [CVP] in six). On ...

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 ...

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 ...

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 ...

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 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 ...

Atrial septal aneurysm (ASA) with diagnosis during life is a rarely reported anomaly, especially when not associated with other congenital or acquired valvular cardiopathies. Among 4,000 routine echocardiograms, 23 cases of ASA were found (8 men and 14 women, aged 19 to 79 years). Three patients had coronary artery disease, ...
Weinreich D J - - 1985
Tricuspid valve prolapse has remained a poorly defined entity. Some authors have stated that prolapse isolated to the tricuspid valve has not been documented. This report contains three cases of isolated tricuspid valve prolapse including the first pathologically confirmed case. A review of worldwide literature including all reported cases of ...
Shapiro L M - - 1985
The prevalence and clinical significance of aortic valve prolapse were determined prospectively in 2000 consecutive patients undergoing routine clinical cross sectional echocardiography. Two hundred and twelve patients were excluded because the aortic cusps were not adequately visualised. Aortic valve prolapse was defined as downward displacement of cuspal material below a ...
Kouvaras G - - 1985
In order to clarify possible links between mitral valve leaflet prolapse and cerebral ischaemic events we carried out a study prospectively over a period of two years on 66 patients (35 men and 31 women) under the age of 50 who suffered from transient cerebral ischaemic attacks or completed strokes. ...
Fox P R - - 1985
An M-mode echocardiographic examination was performed in a consistent manner in 30 clinically healthy cats under light ketamine hydrochloride sedation. There was a significant linear relationship between increasing body size and increasing cardiac dimensions for several echocardiographic values. Positive correlation existed between body weight and body surface area with aortic ...
Tebbe U - - 1985
Patients with mitral valve prolapse (MVP) frequently have chest pain, which may be difficult to differentiate from angina pectoris in coronary artery disease (CAD). We performed resting and exercise ECGs, pulmonary arterial pressure measurements, radionuclide ventriculography (99mtechnetium), and perfusion scintigrams (201thallium) in 56 patients with angiographically proven MVP and no ...
Henderson A - - 1985
34 patients with catheter verified, haemodynamically trivial mitral leaflet prolapse with chest pain and normal coronary arteries were studied. Nineteen had no auscultatory signs of MLP despite clear catheter or echocardiographic evidence of prolapse. Infero-lateral repolarisation changes on the resting electrocardiogram were present in 29%. 50% had false positive exercise ...
van der Bel-Kahn J - - 1985
Ten patients with an average age of 58 years underwent valve replacement because of isolated mitral valve prolapse with severe regurgitation. None had clinical evidence of Marfan's syndrome or another systemic disease that would indicate that a primary connective tissue disorder was the cause of the prolapse. All 10 patients ...
Arditti A - - 1985
Echocardiographic findings in six patients with primary pulmonary hypertension are presented. Four of six patients had abnormal septal motion with prolapse of mitral and tricuspid valves. The other two had none of the three echocardiographic abnormalities. It is possible that hemodynamic changes in ventricular pressure gradients across the interventricular septum ...
Stickels K - - 1985
The inter- and intraobserver variability in applying current diagnostic criteria for mitral valve prolapse as seen on two-dimensional echocardiograms is appreciable. It is therefore proposed that new methods employing computer-based pattern recognition algorithms be developed. The criteria will focus on the shape of the valve throughout systole. Shape analysis is ...
Sakuma T - - 1985
A 54-year-old man with mitral valve prolapse syndrome diagnosed by echocardiography complained of anginal pain associated with ventricular tachyarrhythmia. One day he suddenly lost consciousness, and ECG at that time revealed ventricular fibrillation. Thereafter, he developed ST elevation, sporadic premature ventricular contractions, and R on T phenomenon leading to ventricular ...
Wann L S - - 1985
In order to determine the precision with which currently used echocardiographic criteria can be applied for the diagnosis of mitral valve prolapse, three independent observers (A, B, and C) blindly analyzed the separate M-mode and two-dimensional echocardiograms of 50 patients, 27 of whom had previously been identified clinically as having ...
Barletta G A - - 1985
The high incidence of mitral valve prolapse (MVP) in patients with ischemic attacks is puzzling when compared with the very low incidence of cerebrovascular attacks observed in individuals known to have MVP. Our aim was to determine if it is possible to identify a patient subset with MVP at the ...
