[Biopsy of the heart valves. 872 cases].
In this study, 872 heart valves surgically excised from 810 patients during a period of 5 years (1994 through 1998) were examined pathologically. There was a predominance of aortic (506 patients) versus mitral valves (246 pts.). While aortic valves came more often from men (364) than from women (142), in mitral valves the M:F ratio is 82/164. Isolated calcific aortic stenosis appeared as the most frequent valvular disease (418 pts.), with predominance of its sclerotic-senile type (238 pts.). Mitral stenosis (185 pts.) remains the classical post-rheumatic disease. The relative frequency of a subvalvular stenosing mitral lesion is stressed. The "pure" incompetence of both aortic (70 pts.) and mitral (56 pts.) valve was usually based on valvular myxoid degeneration. An aorto-mitral disease requiring replacement of both valves (51 pts.) presented typically as a post-rheumatic lesion, however, a combination of a post-rheumatic mitral with a degenerative-sclerotic aortic valve disease may be possible. In 30 patients, the valvular replacement was performed for infective endocarditis or a post-IE lesion, mostly of the aortic valve. With the almost non-existence of acute rheumatic fever and with the increasing average age of population in this country, we may expect a long-term decline in mitral valve disease and an increase in aortic valve disease, particularly in the sclerotic type of aortic stenosis.
