Abstract


Summary. The aim was to establish the dynamics of the systolic and diastolic function of the left ventricle of the heart during exercise of different capacities according to echocardiography in athletes with bicuspid aortic valve. To achieve the objectives we have examined 39 athletes aged 8 to 16 years, who were involved in football. In the study group included 9 athletes with bicuspid aortic valve. In the control group included 30 athletes of appropriate age, sex and sports training with normal aortic valve structure. All athletes echocardiography performed during the execution of exercise on a bicycle ergometer. The results showed that athletes with bicuspid aortic valve at rest characterized by increased aortic diameter and deterioration of left ventricular diastolic function (p<0.05). The threshold of tolerance to physical exertion in athletes with bicuspid aortic valve was statistically significantly lower than the control group at the expense of systolic and diastolic function of the left ventricle. Early symptoms of physical overexertion by cardiovascular system in athletes with bicuspid aortic valve was increasing the ratio E/e’. It can be used to diastolic myocardial function reserve diagnostic.
