[Some aspects regarding degenerative mitral valvular lesions encountered in medical practice]

In the last years, the degenerative valvular heart diseases have the tendency to equalize in frequency the rheumatismal valvular diseases. The maximum attention has been paid on the degenerative aortic stenosis as being a lesion with maximum frequency and a severe evolution. This study, given on the 18391 admissions in the period 1997-2001, is a retrospective analyse and it is concerned with the degenerative mitral valvular lesions. Of the 223 patients with degenerative valvular heart lesions, 139 patients (62.3%) had degenerative aortic stenosis and 96 patients (38.5%) were diagnosed with degenerative mitral valvular lesions from which 30 patients have had no association with aortic valvular lesions while 66 patients have had such an association. The pointed out types of mitral lesions were: the mitral insufficiency in 59 patients, the mitral annular calcification without hemodynamic disease in 19 patients, the mitral stenosis in 9 patients and the mitral disease in 9 patients, too. The women was affected nearly 1.7 times more frequent than the men, with a maximum average age greater with four years for women but with a low minimal average age at 60 years for women and 52 years for men. The detailed analyse of this 96 cases had shown the presence of a cholesterol value over 200 mg/dl in 50 patients (52%), the diabetic mellitus of type II in 12 patients (12.5%), an association with HTA in 42 patients (43.7%), the cardiac insufficiency in 68 patients (70.8%), a permanent atrial fibrillation in 24 patients (25%), the chronical myocardiac infarct in 19 patients (19.7%) and disorders in the transmission of stimuli in 8 patients (8.3%). The degenerative mitral valvular lesions had occurred more and more frequently realizing more complex features under the mitral insufficiency predominance. Its frequent association with the degenerative valvular lesions determines the evolutive and therapeutic particularities that are dominated by the high gravity prognostic.
