| Popis: | Background Exercise stress echocardiography (ESE) is routinely used in adults but its role in children (C) is less established Purpose To assess the feasibility and clinical value of ESE in outpatient children Methods We enrolled 309 consecutive C (mean age = 14,1 ± 2,6 years, range 6-17 yrs) who underwent treadmill ESE between 2002 and 2019: One group (Group I) of 258 C including: 237 with exercise related symptoms (chest pain and/or dyspnea and/ or lypotimia-syncope), 15 with resting ECG alterations, 6 with positive ECG stress test and other group of C (Group II) including: 10 asymptomatic for screening requested by parents, 11 with symptoms unrelated to exercise, 12 with antecedents of sudden death in the family, and 17 with known pathology - 10 with hypertrophic cardiomyopathy, 2 with aortic coarctation, 1 each with Cortriatriatum sinister, pulmonary stenosis, subaortic stenosis, bicuspid aortic valve, left ventricular hypertrophy related to arterial hypertension, aortic switch operation. Regional wall motion abnormalities (RWMA) by 2-D and continuous wave Doppler (transvalvular or transaortic or intraventricular (IVG) gradients were assessed in all. Results The success rate was 309/309 (100%). Only one complication (allowing asthma diagnosis by serendipity) occurred: a severe asthmatic crisis in one girl studied because of chest pain with exercise (with ESE negativity), Stress-induced RWMA occurred in 2 pts (one with HCM, the other with normal coronary arteries). A significant orthostatic exercise induced IVG (> 30 mmHg) was present in 101 of the 258 C (39%) studied due to symptoms, ECG alterations or positive stress ECG. In group II the C with induced IVG attained greater heart rate (HR) 184 ± 12 vs 174 ± 16 (p Conclusions Treadmill ESE is feasible and safe in young people. RWMA are of limited usefulness in our outpatient C group. Doppler often documents significant exercise induced IVG, occult at rest that associate with symptoms. Abstract P794 Figure.
