Abstract
Degenerative mitral valve disease causing mitral valve prolapse is the most common cause of primary mitral regurgitation, with two distinct phenotypes generally recognized with some major differences, i.e., fibroelastic deficiency (FED) and Barlow's disease. The aim of this review was to describe the main histological, clinical and echocardiographic features of patients with FED and Barlow's disease, highlighting the differences in diagnosis, risk stratification and patient management, but also the still significant gaps in understanding the exact pathophysiology of these two phenotypes.

Abstract
Aims Filamin-A (FLNA) was identified as the first gene of non-syndromic mitral valve dystrophy (FLNA-MVD). We aimed to assess the phenotype of FLNA-MVD and its impact on prognosis. Methods and results We investigated the disease in 246 subjects (72 mutated) from four FLNA-MVD families harbouring three different FLNA mutations. Phenotype was characterized by a comprehensive echocardiography focusing on mitral valve apparatus in comparison with control relatives. In this X-linked disease valves lesions were severe in men and moderate in women. Most men had classical features of mitral valve prolapse (MVP), but without chordal rupture. By contrast to regular MVP, mitral leaflet motion was clearly restricted in diastole and papillary muscles position was closer to mitral annulus. Valvular abnormalities were similar in the four families, in adults and young patients from early childhood suggestive of a developmental disease. In addition, mitral valve lesions worsened over time as encountered in degenerative conditions. Polyvalvular involvement was frequent in males and non-diagnostic forms frequent in females. Overall survival was moderately impaired in men (P = 0.011). Cardiac surgery rate (mainly valvular) was increased (33.3 ± 9.8 vs. 5.0 ± 4.9%, P < 0.0001; hazard ratio 10.5 [95% confidence interval: 2.9-37.9]) owing mainly to a lifetime increased risk in men (76.8 ± 14.1 vs. 9.1 ± 8.7%, P < 0.0001). Conclusion FLNA-MVD is a developmental and degenerative disease with complex phenotypic expression which can influence patient management. FLNA-MVD has unique features with both MVP and paradoxical restricted motion in diastole, sub-valvular mitral apparatus impairment and polyvalvular lesions in males. FLNA-MVD conveys a substantial lifetime risk of valve surgery in men.

Abstract
BACKGROUND The long-term effects of double valve replacement on left ventricular function in patients with combined severe rheumatic aortic and mitral regurgitation have not been reported previously. Furthermore, the importance of chordal preservation in this group of patients is unknown. METHODS AND RESULTS Serial clinical and echocardiographic evaluations were performed prospectively in 44 patients who underwent double valve replacement for combined aortic and mitral regurgitation. Chordae to the posterior mitral leaflet were preserved in 27 patients. Mean follow-up was 40 +/- 19 months. Left ventricular end-diastolic diameter decreased significantly 3 months after surgery (from 66 +/- 10 to 52 +/- 11 mm; P < .001) without a substantial change in end-systolic diameter, resulting in a significant decline in ejection fraction (from 60 +/- 9% to 48 +/- 15%; P < .001). At 1 year, a significant reduction in end-systolic dimension was observed without a concomitant decline in end-diastolic diameter, thus normalizing the ejection fraction (55 +/- 12%; P = .17 versus baseline). No further changes were seen at latest follow-up. Multivariate regression analysis identified baseline end-systolic diameter and ejection fraction as independent predictors of postoperative systolic performance. Chordal preservation did not emerge as a univariate or multivariate predictor. CONCLUSIONS After an initial postoperative decline in ejection fraction, normalization in left ventricular systolic function may be expected 1 year after double valve replacement for combined rheumatic mitral and aortic regurgitation. End-systolic diameter and ejection fraction are the only independent predictors of postoperative left ventricular performance.

Abstract
A clinico-morphologic study was performed on 1120 patients who underwent aortic valve replacement at the Department of Medical and Surgical Cardiology, 2nd University Medical School of Naples, Naples, Italy, from January 1981 through December 1991. In 69 cases the aortic valve was incompetent due to a non-inflammatory aortic root disease such as myxomatous infiltration of the cusps and or aortic root dilatation. Among these patients males were prevalent (male/female ratio = 2.2). The mean age was 37 +/- 7.5 years. A floppy mitral valve was diagnosed in 16 cases while in one a left atrial myxoma was found. The patients were divided into 3 groups: Group 1-29 patients with aortic root dilatation and normal cusps; Group 2-25 patients with aortic root dilatation and myxomatous infiltration of aortic cusps (floppy aortic valve); and Group 3-15 patients with floppy aortic valve and undilated aortic root. At the gross examination the cusps of the patients in Groups 2 and 3 were redundant, thin, soft and gelatinous. The histology showed myxomatous infiltration with disruption of the fibrous layer. In patients with aortic root dilatation the histology of the aortic root fragments showed a cystic medial necrosis. Deep correlation was found between the root dilatation and the grade of aortic wall cystic medial necrosis. Cusp's diastasis was the cause of aortic regurgitation in patients with aortic root dilatation, while cusp prolapse caused aortic incompetence in presence of the floppy aortic valve and undilated aortic root.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Chronic isolated aortic regurgitation (AR) caused by degenerative, rheumatic, and Marfan etiologies were compared in a study of 87 patients. There were three hospital deaths in the Marfan group, but none in the rheumatic and degenerative groups. The late postoperative survival rates at 5 and 10 years were 98% and 94%, respectively, in the rheumatic group; 84% and 84%, respectively, in the degenerative group; and 85% and 78%, respectively, in the Marfan group. An analysis of the late complications disclosed a higher incidence of aortic dissection and paravalvular leakage in the degenerative and Marfan groups than in the rheumatic group. In the degenerative group, 4 of the 32 patients developed acute aortic dissection within 3 years following aortic valve replacement. The aortic root diameter in these 4 patients was more than 40 mm at the time of surgery, whereas it was less than 40 mm in the remaining 28 patients. In conclusion, considering the progressive nature of myxomatous degeneration, patients with a severely dilated aortic root diameter should be monitored carefully with echocardiography after surgery.

Abstract
The incidence of and the Doppler color-flow echocardiographic characteristics of aortic valve prolapse with nonrheumatic aortic regurgitation were examined. Aortic valve prolapse was observed in 21 of 243 patients (15 men and 6 women) with aortic regurgitation as detected by Doppler color-flow echocardiography (rheumatic, 112; nonrheumatic, 131) in 1247 consecutive patients. Patients with aortic valve prolapse included three patients with essential hypertension and one with annuloaortic ectasia. The remaining 17 patients (7% of those with aortic regurgitation) had no other associated cardiovascular disease (idiopathic aortic valve prolapse). Prolapse of the mitral or the tricuspid valve or both was associated with aortic valve prolapse in seven patients. Aortic regurgitation jet was markedly deviated from the axis of left ventricular outflow tract toward the anterior mitral leaflet or the interventricular septum in 17 of 21 (81%) patients with aortic valve prolapse, whereas 28 of 110 (25%) patients with nonrheumatic aortic regurgitation without prolapse and 17 of 112 (15%) patients with rheumatic aortic regurgitation without prolapse showed the deviation of regurgitant jet (p < 0.001). In conclusion, idiopathic aortic valve prolapse is one of the significant causes of aortic regurgitation, and a marked deviation of regurgitant jet is a characteristic Doppler color-flow echocardiographic finding of aortic regurgitation that results from aortic valve prolapse.

Abstract
Two cases with prolapse of all four cardiac valves are described and compared with two similar ones previously reported. The severity and progression of regurgitation of each of the valves differed by case, despite having similar echocardiographic findings consistent with the diagnosis of multiple floppy valves. Two of the four patients had their aortic valve replaced because of severe regurgitation: the excised valves revealed myxomatous degeneration. None of the patients had any stigmata of Marfan or Ehlers-Danlos syndrome, except for the presence of hyperextensive joints. There may be an unknown collagen disorder that caused floppiness in all the valves.

Abstract
Seventy two consecutive patients with severe isolated aortic regurgitation were evaluated by preoperative echocardiographic and angiographic assessment of the aortic root. Biopsy specimens of the aortic wall were taken at operation. Two major groups of patients were found: those with cusp derangement but normal aortic roots and those with normal cusps but dilated aortic roots. Of the 42 cases of abnormal cusps, 20 were rheumatic, 15 were infective, and six were bicuspid. One patient had a tear in an otherwise normal cusp. Of the 30 cases of abnormal roots but normal cusps, six had inflammatory changes (syphilis, Reiter's disease, giant cell aortitis) and 24 had root dilatation caused by non-inflammatory destruction of elastic laminae. Echocardiographic measurement of the aorta at the level of the top of the commissures predicted the findings at pathology. In 37 of 39 patients with cusp disease the measurement was less than 37 mm. In 27 of 33 patients with root disease the measurement was greater than or equal to 37 mm. This difference was statistically significant. There was no difference in the sizes of the prosthesis used in each group, suggesting that it was the diameter of the junction of the aorta with the sinuses rather than the junction of the sinuses with the ventricle that was important in aortic regurgitation. Clinical progression in patients with non-inflammatory aortic root disease is slower than in patients with infective disease but faster than in those with rheumatic cusp disease.

Abstract
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 microscopic examination, myxomatous degeneration was observed in 20 patients, including six with AVP, 13 with MVP, and one with CVP. In the other 22 patients, including three with AVP, 14 with MVP, and five with CVP, microscopic examination revealed fibrosis with vascularization and scattered infiltration of inflammatory round cells caused by postinflammatory changes with or without chronic inflammation. We coined the term "postinflammatory valve prolapse" (PIVP) to describe these valves. Both postinflammatory and myxomatous degeneration were observed in seven patients with floppy mitral valves attributable to PIVP. Rupture of chordae tendineae was present in six patients with myxomatous mitral valve and three with PIVP. Seven patients with PIVP had a history of rheumatic fever. The results suggest that valvular prolapse is produced not only by myxomatous degeneration but also by postinflammatory changes, including those caused by rheumatic fever.

Abstract
Isolated pulmonary valve prolapse may be a sign of pulmonary hypertension. Three patients with pulmonary hypertension as a result of left ventricular failure, chronic obstructive pulmonary disease, and primary pulmonary hypertension, respectively, are described in the case reports. It is likely that the morphological change of the pulmonary valve is due to exaggeration of the normal convexity of the elastic pulmonary leaflets as a result of a high pulmonary artery diastolic pressure. This two-dimensional echocardiographic sign may prove to be a useful qualitative hallmark for pulmonary hypertension. Present methods to detect pulmonary hypertension by two-dimensional echocardiography rely on remote findings of right heart abnormalities or changes in systolic time intervals. Pulmonic valve prolapse is the first direct sign of pulmonary hypertension found on two-dimensional echocardiography.

Abstract
Inherited abnormalities of connective tissue elements often cause changes in the structure and function of the cardiovascular system. Well-known heritable disorders of connective tissue in which cardiovascular abnormalities are prominent include the Marfan syndrome and the Ehlers-Danlos syndrome. Connective tissue abnormalities also occur without the associated features of a recognized syndrome. These include isolated valvular prolapse and anuloaortic ectasia. In this review, the cardiovascular features of connective tissue abnormalities--both the recognized syndromes and the isolated abnormalities--are described, important concepts in the diagnosis and treatment of these disorders are reviewed, and the classification of inherited connective tissue abnormalities of the cardiovascular system is discussed.

Abstract
The purpose of this study of 6 cases of Marfan's or Marfan-like syndrome detected in 7077 echocardiographic examinations was to investigate the clinical value of echocardiography. The mean age of the patients was 40 years, and 4 of them (66 p. 100) were female. The diagnosis was based on the 4 criteria of Marfan's syndrome in 1 case, on 3 criteria in 2 cases and on 2 criteria in 3 cases. Four patients were known to have a previous cardiac murmur. Auscultation revealed a systolic murmur of mitral regurgitation in 3 cases (associated with a diastolic murmur of aortic regurgitation in 2 of them), a diastolic murmur of aortic regurgitation in 3 cases and a systolic murmur due to calcified bicuspid aortic valve in 1 case. ECG recorded a normal rhythm in 4 cases, atrial fibrillation in 2 cases of mitral regurgitation, and left ventricular hypertrophy in 3 cases. Chest X-ray showed cardiomegaly in 3 patients and severe kyphoscoliosis in one. Echocardiography visualized dilatation of the ascending aorta, severe (60 mm) in 1 case, in 3 patients; dilatation of the pulmonary artery in 1 patient; pansystolic mitral valve prolapse in 3 patients (associated with aortic and tricuspid valve prolapse in 2 of them after the disease had progressed); isolated aortic valve prolapse due to bicuspid valve in 2 patients; intracardiac calcifications in 3 patients; subaortic septal hypertrophy in 1 patient and calcified incompetent foramen ovale in 1 patient. Aortography performed in 3 patients disclosed an aneurysm of Valsalva's sinuses in 1 case and a mild aortic insufficiency in 2 cases. Two patients underwent cardiac catheterization for severe mitral regurgitation due to mitral valve prolapse requiring valve replacement, which was successfully done. Thus, echocardiography may provide an early diagnosis of Marfan's syndrome, since cardiovascular abnormalities are frequent in infancy. It also ensures a close follow-up of the disorders and it is useful in deciding whether treatment should be medical or surgical. It may detect formes frustes in a family with Marfan's syndrome, and it may define a borderline group of patients: those with Marfan-like syndrome. In these patients the cardiovascular lesions are more preponderant and appear later than in the classical Marfan's syndrome; they are often difficult to differentiate from the lesions of Barlow's syndrome.

Abstract
A clinico-pathologic study was performed in 25 patients undergoing aortic valve replacement because of regurgitation, caused by myxoid degeneration of the valve leaflets. Associated cardiac anomalies were floppy mitral valve (2 cases), floppy mitral valve and idiopathic hypertrophic subaortic stenosis (1), left atrial myxoma (1), and aortic coarctation at the isthmus (1). Three patients died (2 immediately and 1 on the 30th postoperative day). Pathological studies of the explanted valves showed deformities characterized by redundant thin leaflets which appeared soft and gelatinous. On histologic examination the fibrous layer of the leaflets was seen to be infiltrated by myxomatous tissue. Echocardiography showed the aortic root to be dilated in 13 patients and normal in the others. In those with normal aortic root, the histological examination of aortic wall disclosed minimal cystic medial necrosis in two cases. In contrast, more severe forms of cystic medial necrosis were evident in all patients having a dilated aortic root. Aortic valve replacement was performed in all cases. It was accompanied by a Bentall procedure (1 case), repair of ascending aorta dissection (2), replacement of the ascending aorta (1), mitral valve replacement (2), mitral valve replacement and apico-ascending aorta conduit (1) and excision of a left atrial myxoma (1). Our experience suggests that prolapse of the aortic valve due to floppy leaflets is a common degenerative disease which is generally associated with noninflammatory aortic root degeneration. This, together with aortic root dilatation, contributes to valve insufficiency. Nevertheless, the disease, when isolated (with normal aortic root), is liable in itself to produce aortic regurgitation. The need for early diagnosis is stressed, so as to be able to perform valve replacement.

Abstract
Twelve patients (5 male and 7 female; mean age 17.7 +/- 12.3 years, range 5 to 42) with Marfan's syndrome and 48 of their first degree relatives (16 male and 22 female; mean age 29.8 +/- 17.3 years, range 4 to 60) were evaluated for cardiac abnormalities by echocardiography. Of the patients with Marfan's syndrome, aortic valve prolapse was present in 1, tricuspid valve prolapse in 4, mitral valve prolapse in 12 and aortic root dilation in 10. Of the 48 first degree relatives of these 12 patients, tricuspid valve prolapse was diagnosed in 3, mitral valve prolapse in 15 and aortic root dilation in 12; aortic valve prolapse was not observed in any of these subjects. Of the 60 persons studied in these 12 kindreds, 28 (47%) had cardiac involvement. Among the 28 with cardiac involvement, aortic valve prolapse was observed in 1 (3.5%), tricuspid valve prolapse in 7 (25%), mitral valve prolapse in 27 (96%) and aortic root dilation in 22 (79%). Mitral valve prolapse was also present in the seven subjects with tricuspid valve prolapse and one with aortic valve prolapse. In 32 of the 60 persons studied in the 12 families, at least one abnormality of the cardiac, skeletal or ophthalmologic system was observed. Nineteen subjects were younger than 18 years of age; all had cardiac involvement associated with Marfan's syndrome. The notably earlier presentation of cardiac involvement in young persons may be responsible for a shorter life span in this group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
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 isolated tricuspid valve prolapse is also presented. Although signs and symptoms are similar to those found with mitral valve prolapse, tricuspid valve prolapse may occasionally be differentiated by auscultation. The diagnostic criteria of tricuspid valve prolapse are thoroughly discussed for each of the presently available invasive and noninvasive techniques. Right heart catheterization can define such prolapse but is invasive and requires meticulous technique. Two-dimensional echocardiography supersedes M-mode because of the superior spatial evaluation of the tricuspid leaflets in relation to the right atrium and ventricle. Multiple views including a long-axis view of the right ventricular inflow are often required. This parasternal echocardiographic window is often the only one which permits adequate visualization of the posterior leaflet. The pathologic findings of tricuspid valve prolapse are similar to those of mitral valve prolapse. This report concludes with a description of associated conditions. Severe tricuspid regurgitation has not been noted with tricuspid valve prolapse in the absence of superimposed disease, yet much remains undefined concerning the clinical significance of this condition.

Abstract
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 line joining the points of attachment of the aortic valve leaflets. Twenty four cases of aortic valve prolapse (1.2%) were identified. The patients were aged 12-64 years and nine were women. All had underlying valvar heart disease and the commonest lesion (in 11 cases) was prolapse of the larger cusp in bicuspid valves. Aortic valve prolapse was seen in four patients with mitral valve prolapse (two with severe regurgitation), one of whom had marfanoid aortic root dilatation. The remaining examples of aortic prolapse were seen in patients with various disorders including one with pulmonary atresia, two with aortic root disease (one with dissection and one with idiopathic dilatation), and one case of severe mitral regurgitation. Valves destroyed by infective endocarditis were seen in two cases. Aortic valve prolapse may be detected in various cardiac disorders and does not imply the presence of aortic regurgitation, but when bicuspid aortic valves are present it may well be important in producing such regurgitation. Although aortic valve prolapse may be associated with severe forms of mitral valve prolapse, these patients rarely have aortic regurgitation.

Abstract
A 72 year old woman was thought to have a paradoxically split second heart sound. Echocardiography with simultaneous phonocardiography revealed a late systolic click resulting from isolated tricuspid valve prolapse. Respiratory variation of the click in relation to the second heart sound resulted in an auscultatory phenomenon simulating paradoxical splitting of the second heart sound.

Abstract
Although aortic valve prolapse (AVP) has been suggested as a cause of aortic regurgitation (AR) in patients with bicuspid aortic valves, neither the frequency of AVP nor its relation to AR in this setting has been defined. To assess these relations, 64 patients with bicuspid aortic valves diagnosed by 2-dimensional echocardiography and 20 normal subjects, similarly distributed according to age and sex, were studied. The presence and degree of AVP were defined using 3 quantitative terms: aortic valve prolapse distance (AVPD), area (AVPA) and volume (AVPV). Each was corrected (c) for patient size with reference to the diameter of the aorta at the level of insertion of the valve cusps. In normal subjects, the AVPDc averaged 0.09 +/- 0.06 (range 0 to 0.16) and the AVPAc averaged 0.08 +/- 0.06 cm (range 0 to 0.15). In patients with bicuspid aortic valves, the AVPDc averaged 0.26 +/- 0.10 (range 0.11 to 0.59, p = 0.00005 vs normal subjects), whereas the AVPAc averaged 0.35 +/- 0.17 cm (range 0.05 to 0.90, p = 0.00005 vs normal subjects). When the AVPDc criteria were used, 81% of the bicuspid valves were abnormal; when the AVPAc criteria were used, 87% were abnormal. The degree of prolapse defined by the AVPVc, which considers both cusp area and degree of apical displacement, was significantly greater for patients with bicuspid aortic valve with clinical AR than for those without (p = 0.008). However, because of the overlap between groups, there was no point at which this measure uniquely separated patients with and without AR.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The cardiac complications of systemic lupus erythematosus (SLE) include a multitude of valvular, myocardial, and pericardial abnormalities resulting from acute and chronic inflammation involving the endocardium, myocardium, and/or pericardium. A case of acute, severe, aortic, and mitral insufficiency occurring as discrete complications of consecutive flares of SLE in the same patient is described with particular emphasis on the clinical and gross pathologic findings. The cardiac complications of SLE, both from a pathologic and clinical standpoint, are reviewed in the context of the uniqueness of this case.

Abstract
Tricuspid regurgitation is often not apparent on physical examination and several methods are now available to aid in this difficult assessment. Cardiac catheterization using right ventriculography, previously considered the diagnostic standard, has several limitations. Currently available noninvasive tools such as M-mode and two-dimensional echocardiography (with or without contrast), Doppler techniques and even radionuclide cardiologic imaging have added significantly to the precise assessment of the presence and severity of tricuspid regurgitation. This review examines the comparative use and limitations of these various techniques.

Abstract
A previously healthy 34-year-old Dutch immigrant to Australia died unexpectedly in his sleep. At autopsy the only significant finding was a floppy aortic valve (FAV). Histologic, histochemical and electron microscopic studies corroborated the macroscopic diagnosis. Previously described associations of the FAV include the floppy mitral valve, Marfan's syndrome, aortic root dilatation and aortic cystic medial necrosis. None of these features were found in the present case which is the first recorded example of isolated FAV presenting as sudden death. The mechanism of death is obscure, and while it is presumed to be dysrhythmic, a detailed histological examination of the cardiac conducting system revealed no anatomic abnormality.

Abstract
The association between mitral valve prolapse (MVP) and atypical chest pain has been well-described. Numerous theories have been proposed to explain this association. A number of lines of evidence suggest that underlying ischemia may cause chest pain in some patients with MVP. We have recently evaluated 4 patients with chest pain syndromes who had angiographic evidence of MVP and spasm of angiographically normal coronary arteries. The possibility that coronary spasm is the underlying etiology of chest pain in some patients with mitral valve prolapse raises a theoretical argument against beta-blockade in these patients. Three of our patients were successfully treated with calcium channel blockers.

Abstract
The tricuspid valve was examined by 2-dimensional (2-D) echocardiography in 14 patients with tricuspid valve prolapse (TVP) and in 16 normal subjects. Individual leaflets were identified anatomically and for frequency of prolapse. Maximal and minimal anular sizes were measured. Multiple tomograms of the tricuspid anulus were recorded at 30 degrees intervals around the tricuspid anulus with the transducer placed at the right ventricular apex. Anuli were reconstructed from the 6 planes and corrected for body surface area. Three leaflets of the tricuspid valve could be anatomically identified in all patients. Prolapse of all 3 leaflets was observed in 6 patients, 2 leaflets in 5 and 1 in 3. Frequency of individual leaflet prolapse was 93% for the septal cusp, 86% for the anterior and 43% for the posterior. Maximal anular circumference and area in TVP were 7.9 +/- 0.6 and 8.9 +/- 1.3 cm2/m2, respectively--significantly larger than values in normal subjects (6.4 +/- 0.5 cm/m2 and 6.1 +/- 0.9 cm2/m2, respectively) (p less than 0.001). Percent reductions in circumference and area in TVP were 14 +/- 3 and 25 +/- 5%, respectively--significantly smaller values than in normal subjects (19 +/- 4 and 33 +/- 4%, respectively). Tricuspid regurgitation (TR) was detected by contrast echocardiography in 7 of 14 patients with TVP. The severity of TR appeared to be minimal in 6 of the 7 patients, and was not associated with an increase in anular size. Thus, TVP is associated with anular dilatation irrespective of associated TR, probably as a primary pathologic characteristic.

Abstract
Sixty-two patients diagnosed as having mitral valve prolapse, 60 to 81 years old, presented with disabling chest pain (20), symptoms of arrhythmias including palpitations and syncope (16), or mitral regurgitation (MR) with symptoms of congestive heart failure (26). The diagnosis of MVP was made on the basis of a combination of classic auscultatory, echocardiographic and angiographic findings. Thirteen of the 20 patients with chest pain had normal coronary angiograms and 7 had significant coronary artery disease (CAD). Patients with CAD could not be differentiated by clinical presentation alone. Furthermore, the incidence and types of arrhythmias, the presence of a positive stress test, and hemodynamic findings were similar in all patients in this group whether or not CAD was present. The 16 patients with palpitations had a broad spectrum of rhythm disorders, including both supraventricular and ventricular arrhythmias. Two patients had prehospital "sudden death" and 2 others had systemic emboli. Twenty-one of the 26 patients with MR had valve surgery. Intraoperatively the valves were described as enlarged, floppy and with redundant leaflets. Histologic examination showed extensive "myxomatous" changes throughout the valve leaflets. Thus, mitral valve prolapse is a cause of symptomatic heart disease in the elderly. It has a predictable pattern of clinical presentation and should be considered in the differential diagnosis of older patients with disabling chest pain and arrhythmias and as the cause of progressive or severe MR.

Abstract
Although mitral regurgitation and fibromyxomatous thickening of the mitral leaflets have long been recognized as such, mitral valve prolapse has only recently been added as one of the pleiotropic features of the Marfan syndrome. The prevalence, age of onset, and natural history of mitral valve dysfunction in this condition are uncertain. Therefore, all patients in one clinic who met strict diagnostic criteria for the Marfan syndrome and who had clinical and echocardiographic examinations before age 22 years were reviewed. Of the 166 patients (84 males, aged 11.9 +/- 0.6 years [mean +/- SEM]; and 82 females, 11.0 +/- 0.6 years), 52 percent had auscultatory and 68 percent had echocardiographic evidence of mitral valve dysfunction, generally mitral valve prolapse. Prevalence did not differ between the sexes. Follow-up in 115 patients averaged five examinations over a mean of four years; 17 percent were followed for more than six years. Criteria for progression of mitral valve dysfunction were: (1) on auscultation, the appearance of new systolic clicks or apical systolic murmurs, a mitral regurgitant murmur increased by two grades, or appearance of congestive heart failure not due to aortic regurgitation; and (2) on echocardiography, the new appearance of mitral valve prolapse or abnormally increased left atrial dimension. Nearly half the patients met at least one criterion and one quarter had both auscultatory and echocardiographic evidence of progressive mitral valve dysfunction. Twice as many females demonstrated worse mitral valve function with time. Eight of the 166 patients either died as a result of mitral valve dysfunction or required mitral valve replacement. Severe mitral regurgitation developed in an additional 15 patients. Rupture of chordae tendineae was uncommon. Antibiotic prophylaxis was routine, and no cases of bacterial endocarditis of the mitral valve occurred. These results suggest that mitral valve dysfunction is extremely common in young patients with Marfan syndrome and usually presents as mitral valve prolapse. Serious mitral regurgitation develops in one of every eight patients by the third decade. Thus, the prevalence and natural history of mitral valve prolapse in the Marfan syndrome appear distinct from mitral valve prolapse associated with other conditions, including idiopathic or familial mitral valve prolapse.

Abstract
The tricuspid valve was studied in 143 subjects using two dimensional echocardiography. The groups studied were 40 normal subjects, 31 patients with mitral valve prolapse, 22 with clinically probable tricuspid valve prolapse, 20 with congestive cardiac failure, and 30 with miscellaneous cardiac conditions but no features of right heart disease. Using multiple views it was possible to record all three leaflets in 74.8% of cases and anterior and septal leaflets in 95%. Prolapse of the tricuspid valve was recognised in 13 patients: six (19.5%) of the group with mitral valve prolapse and seven (6%) of the remaining patients. Prolapse of all three leaflets was shown in one patient, anterior and septal prolapse in six patients, anterior and posterior in three patients, septal leaflet prolapse alone in two patients, and anterior alone in one patient. Two dimensional echocardiography allows definition of individual tricuspid leaflets and prolapse of any or all leaflets can be diagnosed. Tricuspid valve prolapse is commonly associated with prolapse of mitral valve leaflets but isolated cases are recognised.

Abstract
Isolated mitral valve prolapse (MVP) may represent one end of a spectrum of disease involving dysfunction of multiple cardiac valves. Eighty-nine consecutive patients with MVP diagnosed by two-dimensional echocardiography (2-D echo) were prospectively studied specifically to determine the incidence of tricuspid valve prolapse (TVP) and its clinical correlations. Criteria for prolapse of the atrioventricular (A-V) valves by 2-D echo included extension of the valve leaflets behind an imaginary line defining the valve annulus. Forty-one of 82 patients with MVP had associated TVP. No significant differences existed between patients with isolated MVP and combined A-V valve prolapse with regard to sex, clinical history, symptoms, or physical examination. The parasternal long axis view was more sensitive than the apical four chamber view in diagnosing prolapse of either mitral or tricuspid valves. Thus, TVP is a frequent concomitant of MVP and occurs with equal frequency in both young and old patients.

Abstract
The following distinctive combination of M-mode and two dimensional echocardiographic abnormalities of the aortic valve was observed in a group of 12 patients, of whom 11 had mitral valve prolapse. On two dimensional scans, the aortic cusps were freely mobile but appeared thickened or folded. On M-mode records, cusp excursion was normal: there was well defined systolic oscillation, and cusp echoes were multiple and centrally positioned within the aortic root during diastole. The aortic valve was inspected at operation in two patients: a typically myxomatous valve was replaced in one and findings were in keeping with this diagnosis in the other. It is suggested that the echocardiographic features described are characteristic of the floppy aortic valve. Despite the echocardiographic abnormalities, only three patients had clinical evidence of an aortic valve lesion. It is, therefore, further suggested that the investigation of patients with mitral prolapse should include echocardiographic assessment of the aortic valve, even when associated myxomatous degeneration of that valve is not suspected clinically.

Abstract
The patterns of aortic and tricuspid valve motion in 50 patients with mitral valve prolapse were analyzed by wide-angle, phased-array, two-dimensional echocardiography. Twelve patients (24%) had redundant aortic leaflets bulging into the left ventricular outflow tract during diastole. Eight of 12 patients had aortic regurgitation and seven of 12 had M-mode echocardiographic evidence of aortic valve prolapse. One patient underwent mitral and aortic valve replacement, and the excised valves revealed marked myxomatous degeneration. Eight of 15 patients undergoing contrast echocardiography had tricuspid regurgitation (systolic reflux of contrast material into the inferior vena cava persisting for more than 10 beats), and prolapse in the septal leaflet of the anterior leaflet or both. A similar tricuspid valve pattern was noted in three of seven patients without tricuspid regurgitation. Tricuspid valve prolapse was identified in 20 patients (40%). Nine patients (18%) had combined prolapse of the mitral, aortic and tricuspid valves. In five patients with middiastolic high-pitched murmurs recorded along the left sternal border, tricuspid valve prolapse was demonstrated. In one of these patients, the presence of pulmonary regurgitation was confirmed by intracardiac phonocardiography. We conclude that two-dimensional echocardiography is useful for evaluating patients with combined valvular prolapse syndrome.

Abstract
The mitral valve prolapse syndrome may present with a variety of clinical manifestations and has proved to be a common cause of nonspecific cardiac symptoms in clinical practice. Primary and secondary forms must be distinguished. Myxomatous degeneration appears to be the common denominator of the primary form. The diagnostic standard of this form has not previously been defined because the detection of mitral leaflet tissue in the left atrium (prolapse) on physical examination or angiography is nonspecific. M mode echocardiography has greatly enhanced the recognition of this syndrome but has not proved to be the best diagnostic standard because of its limited view of mitral valve motion. The advent of two dimensional echocardiography has provided the potential means for specific identification of the mitral leaflet motion in systole and can be considered the diagnostic standard for this syndrome. Primary myxomatous degeneration with leaflet prolapse is not localized to the mitral valve. Two dimensional echocardiography has detected in preliminary studies tricuspid valve prolapse in up to 50 percent and aortic valve prolapse in about 20 percent of patients with idiopathic mitral valve prolapse.

Abstract
Four hundred and ninety-nine surgically excised valves were examined for pathological evidence of myxomatous degeneration. Thirty-six valves (7%) had myxomatous degeneration as a major pathological finding. Fourteen valves (3%) had significant myxomatous degeneration of the pars fibrosa, a finding which we define as "primary myxomatous degeneration". Echocardiographic findings and catheterisation results were correlated with the clinical course, surgical results, and follow-up in these 14 patients. Echocardiograms in 10 of the 11 patients who had them (91%) showed abnormalities suggesting the presence of primary myxomatous degeneration. Echocardiography was more helpful than angiography in diagnosis. The histological pattern of primary mitral myxomatous degeneration appears to be identical to that seen in patients with mitral valve prolapse and five of six patients with mitral lesions had echocardiographic evidence of prolapse. None of the patients with primary myxomatous degeneration of the aortic valve had syphilis of Marfan's syndrome. While the aetiology of primary myxomatous degeneration of cardiac valves is not known, a link to a more generalised disorder is suggested.

Abstract
The accuracy of combined clinical and noninvasive cardiac diagnostic evaluation was prospectively examined in 108 consecutive patients referred to the heart station for echocardiographic examination prior to cardiac catheterization. History, physical examination, scalar electrocardiology, chest roentgenography, phonocardiography and pulse recording, and M-mode echocardiography were employed by the heart station cardiologist, who assigned one or more diagnoses to each patient. In addition, one of three management strategies was proposed for each patient: 1) surgery without cardiac catheterization; 2) medical therapy without cardiac catheterization; or 3) cardiac catheterization for clarification of the diagnosis. The results of the combined clinical and noninvasive evaluation were independently reviewed for each patient and compared with the diagnosis determined by cardiac catheterization, results of cardiac surgery, and total hospital course. Diagnostic predictions employing combined clinical and noninvasive cardiac evaluation were completely correct in 86% of patients, and management strategy was correct in 97% of individuals. In approximately one-half of all patients full cardiac catheterization or coronary arteriography was recommended. All management strategy errors and two-thirds of diagnostic errors occurred in patients with mitral regurgitation, aortic regurgitation, or coronary artery disease. Combined clinical and noninvasive evaluation results in accurate diagnostic information adequate for the formulation of appropriate management strategies in the majority of patients, but many individuals with cardiac disease still require invasive evaluation for complete diagnosis.
