The clinical and pathological features of four patients with intractable heart failure, due to myxomatous change in the mitral valve, are described. It is suggested that this change may represent a response of ageing connective tissue to mechanical stress.
متن کاملFloppy Mitral Valve, Mitral Valve Prolapse, and Mitral Valvular Regurgitation.
It is well recognized that the floppy mitral valve (FMV) complex is the central issue in the FMV, mitral valve prolapse (MVP), and mitral valvular regurgitation (MVR) story. MVP associated with the FMV results from the systolic movement of portions or segments of the FMV complex into the left atrium (LA). Prolapse of the FMV results in unique forms of mitral valvular dysfunction and MVR. When t...
متن کاملThe floppy mitral valve. Study on pathogenesis.
The pathogenesis of the floppy valve syndrome is not fully solved. An almost invariable histological finding is the great accumulation of mucinous material in the valve leaflets and constitutes the basis of the valvular theory of the syndrome. The presence of a mucinous layer in normal valves-- the zona spongiosa--is not well recognised. To establish the normal range of the extent of this zone,...
متن کاملThe myxomatous mitral valve and sudden death.
The clincopathologic features of 14 cases of sudden death attributable to dysrhythmias associated with the myxomatous mitral valve are described. The patients were 14-59 years old (mean 27 +/- 11 years). Eleven were female and three male. Of the seven ECGs available, none showed prolongation of the QT interval, but two showed repolarization abnormalities. The material was classified according t...
متن کاملFloppy eyelid syndrome.
The results of clinical examinations and follow-up of 7 patients with floppy eyelid syndrome are presented. The most prominent features of the syndrome are floppy upper eyelids that can be easily everted, with papillary conjunctivitis and punctate keratopathy. The ocular changes seem to be the result of an underlying metabolic (or endocrine) disorder. In the patient with the longest follow-up p...
