Abstract
Aim. To determine prognostic opportunities of echocardiography (ECG) in infectious endocarditis (IE)
basing on the assessment of microbial vegetations size and degree of valvular failure.
Material and methods. Of 114 patients with definite IE (72 male, 42 female), 90 ones had primary
and 24 secondary endocarditis. The prospective study included all the survivors in the IE active stage -78 patients.
Results. Vegetations > 1 cm in size were detected in 50.8%patients, < 1 cm - in 49.2%. Hospital lethality
in vegetations > 1 cm and < 1 cm was 25.8 and 16.1%, respectively. Thromboembolism rate
was 81 and 64.2%, respectively. One-year survival was 78.7 and 71.4%, two-year survival 66.5 and
61.7%, three-year survival 66.5 and 49.4%, five-year survival - 51.7 and 32.9% in vegetations < 1
cm and > 1 cm, respectively. Valvular regurgitation of the first degree was in 17.5%, of the second degree - in 41.9%,
thirdfourth degree - in 36.6% patients. Hospital lethality in mitral valve failure
was 32.1%, in aortic and tricuspid failure - 17.8 and 11.4%, respectively.
Conclusion. EchoCG was most effective for predicting thromboembolism and cardiac failure. Valvular
regurgitation of the third-fourth degree significantly correlates with severe cardiac failure. ECG is less
informative for predicting hospital lethality.
