The syndrome has mitral valve prolapse

In this Chapter we are not able to describe the Genesis of systolic noise in athletes. This issue is devoted to a fairly large literature.
You need to focus on just one of the possible causes of systolic noise at the top, namely syndrome, mitral valve prolapse.
SPMK is a retraction of one or both cusps of the mitral valve into the left atrium, occurs when the left ventricular systole. This retraction creates conditions for the emergence of regurgitation (and hence systolic noise), the degree of which depends on the depth zapadenia of valve cusps. According to most of the authors who studied the syndrome has mitral valve prolapse, it can be both anatomical and functional changes of the four main structures - shutters mitral valve, hartalega apparatus, mitral ring and finally, the left ventricle.
Typical auscultatory signs of the syndrome of mitral valve are late systolic murmurthat follows for more tone - systolic click arising in the middle of systole and called mesocestoides click. All this is clear enough phonocardiographic picture.
With the advent of echocardiography method that allows you to see the movement of the valves of the mitral valve, symptoms of mitral valve received a clear objective evidence (Fig. 3), and in the literature began to appear more and more works devoted SPMK found among persons seeking medical advice about the various complaints (for an indefinite pain in the heart, shortness of breath, malaise, heart rhythm disturbances and so on).
We conducted echocardiographic examination of several hundred young people have no complaints showed that the syndrome has mitral valve prolapse can be one of the reasons of occurrence of functional systolic noise. It turned out that in healthy people with the presence of so-called functional systolic murmur syndrome mitral valve prolapse occurs in 22,7%, while among persons without systolic noise - 8%, with significant difference between athletes and non-athletes have not been found (respectively of 15.3% and 12.5%).
Thus, firstly, it turned out that the syndrome of mitral valve may not show any symptoms and meet young healthy people. Secondly, SPMK in some cases, causes so-called functional systolic noise in athletes. The disappearance of a number of athletes functional systolic noise with age suggests that adaptation to physical activity contributes to the strengthening of the papillary muscles and eliminate SPMK.
Yet it is impossible to consider the issue of the syndrome, mitral valve prolapse finally resolved, and if at the present time there are no good reasons not to allow individuals with the syndrome, mitral valve prolapse to practice sports, they do require careful medical supervision.
