[Moderate or severe aquired valvular heart disease in pregnancy--what does determine the management? Experence, intuition or guidelines?].

Epidemiology of acquired valvular heart diseases has changed significantly over last decades. Degenerative aortic valve stenosis is the most common acquired valvular disease with high prevalence in elderly population. Another common disorder is ischemic mitral regurgitation secondary to myocardial infarction. Both above-mentioned heart disorders are not typical for women in reproductive age. Rheumatic heart valve disease has become infrequent in Polish population. Mitral stenosis, the most prevalent of rheumatic valvular disorders, affects 5% of pregnant women with heart disease and rheumatic aortic stenosis is responsible for 0.5-3% of heart diseases in this population. Despite the fact that acquired valvular disorders are becoming less common among pregnant women, they still remain an important issue and their management should be well known. Discussion about pregnancy should be a part of management of young women with valvular heart disease. Severe valve disorders should be corrected when planning pregnancy. The final management should always be based on collaborative decision made by the patient and health professionals.
