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. First, patients were examined using the usual standard M-Mode echocardiography( left parasternal third or fou...
متن کاملMyxomatous Mitral Valve with Prolapse and Flail Scallop
BACKGROUND Myxomatous mitral valve with prolapse are classically seen with abnormal leaflet apposition during contraction of the heart. Hemodynamic disorders can result from eccentric mitral regurgitation usually caused by chordae tendinae rupture or papillary muscle dysfunction. Echocardiography is the gold standard for evaluation of leaflet flail and prolapse due to high sensitivity and speci...
متن کاملMarcus-gunn phenomenon with- mitral valve prolapse
Marcus-gunn phenomenon is a congenital and sometimes hereditary anomaly, in which a ptotic eyelid retracts momentarily when the mouth is open, or the jaw is moved. These associated movements attributed to abnormal connections between the central mechanisms innervating the pterygoid and elevator muscles. Sometimes this anomaly is associated with dual,s retraction syndrome, duplex kindneys and ur...
متن کاملNew locus for autosomal dominant mitral valve prolapse on chromosome 13: clinical insights from genetic studies.
BACKGROUND Mitral valve prolapse (MVP) is a common disorder associated with mitral regurgitation, endocarditis, heart failure, and sudden death. To date, 2 MVP loci have been described, but the defective genes have yet to be discovered. In the present study, we analyzed a large family segregating MVP, and identified a new locus, MMVP3. This study and others have enabled us to explore mitral val...
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...
