Pulmonary function studies in patients with prolapse of the mitral valve.
نویسندگان
چکیده
We studied the pulmonary function and chest x-ray films of 20 nonsmokers with idiopathic prolapse of the mitral valve. Forty-five percent of these patients complained of dyspnea. Of the 16 chest films reviewed, 44 percent had radiographic evidence of pectus excavatum and 25 percent thoracic scoliosis. The most common pulmonary function abnormalities were increased residual volume (63 percent) and a reduced steady state diffusing capacity (50 percent of patients). There was no relationship between the presence of dyspnea and either chest wall deformity of abnormality of pulmonary function. These pulmonary function abnormalities may reflect a pulmonary parenchymal disorder possibly secondary to a connective tissue abnormality in the lung.

Effect of position on echocardiographic diagnosis of mitral valve prolapse
Echocardiography has been accepted as the diagnostic modality of choice for mitral valve prolapse (MVP). The determine the effect of position on echocardiographic diagnosis of MVP, we examined 693 consecutive patients referred to the echocardiography laboratory because of suspected MVP.

متن کاملE VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...

SUMMARY: The mitral valve prolapse syndrome (MVPS) is a common cardiac disorder, occurring in five percent of general population. An association has been claimed between MVPS and psychiatry disorders. In this study 648 patients (mean age 32.2 years, 411 female .237 male subjects) with echocardiographically confirmed MVPS were tested for psychiatry disorders, and compared with 660 control group...
متن کاملAssociation between Body Mass Index and Mitral Valve Prolapse
Introduction: Body mass index (BMI) can affect cardiac morphology; however, the relationship between BMI and valvular heart diseases has not been thoroughly evaluated. This study aimed to determine the relationship between BMI and mitral valve prolapse (MVP) as one of the most common valve diseases worldwide. It can help us to better understand pathophysiology of this common disease. Materials ...
متن کاملCORRECTED QT DISPERSION IN CHILDREN WITH ISOLATED UNCOMPLICATED MITRAL VALVE PROLAPSE
Mitral valve prolapse (MVP) is a relatively frequent valvular abnormality. In both children and adults with MVP, an increased incidence of ventricular arrhythmias has been reported. QT dispersion, defined as the difference in duration between the longest QT interval and the shortest one, for a given set of electrocardiographic leads has been proposed as a sign of regional difference in card...
