ABSTRACT
The purpose of this study was to evaluate the spectrum of morphologic and functional cardiac involvement in a selected population of patients with systemic lupus erythematosus (SLE) by means of echocardiography. Thirteen patients (2 male and 11 female) affected by SLE, mean age 41.9 years (range, 21-64), underwent M-Mode, two-dimensional and Doppler echocardiography. Eleven patients had renal disease and 3 of them were undergoing dialysis. One patient had findings of active disease. Six patients had systemic hypertension. None had a history suggestive of rheumatic fever or infective endocarditis. At echocardiographic study nine patients demonstrated findings of valvular involvement. These alterations were defined, according to the echocardiographic features, in two types vegetation (verrucous Libman-Sacks endocarditis) and thickening. Vegetations were present in 6 patients, involving the mitral valve in all six and the aortic valve in three. The mitral valve vegetations were more frequent on the subannular portion of the posterior leaflet. Seven patients had valvular thickening involvement of both mitral and aortic valve was present in five, and isolated mitral or aortic valve lesions in the remaining two patients. Combined valvular vegetation and thickening were observed in 4 patients. Eight patients had mild valvular dysfunction on Doppler examination five isolated mitral regurgitation, two combined mitral and aortic regurgitation and one combined mitral stenosis and regurgitation. In agreement with previous reports, our study shows that valvular involvement in SLE is relatively frequent. Echocardiography can identify additional patterns of valvular lesions different from the known "verrucous Libman-Sacks endocarditis". The degree of valvular dysfunction is not important.
