The aim: To improve efficacy of the right ventricle functional condition evaluation in children with tetralogy of Fallot after surgical correction by estimation of instrumental markers of myocardial dysfunction. Materials and methods: We completely examined 35 children with tetralogy of Fallot after their surgical correction at the age of 3 – 17 years. For all the patients was presented tissue doppler. We evaluated peak myocardial velocities of right ventrical in different phases of the heart cycle (S, E`, A`), tricuspid annular plane systolic excursion (TAPSE), diastolic myocardial velocities ratio (E/E`), peak myocardial velocity during isovolumic contraction (IVV), isovolumic relaxation time (IVRT). Results: All children of the study group had pulmonary insufficiency of different severity with main predominance of mild pulmonary regurgitation (20 patients, 57,14±8,36 %). Children with tetralogy of Fallot after surgical correction were admitted with: decreased TAPSE up to 1,39±0,28 cm, decreased S` up to 8,00±1,90 cm/s, and decreased IVV up to 5,69±0,95 cm/s that is significantly lower results of the healthy children. Severe pulmonary regurgitation usually followed by high chances of the right ventricle systolic dysfunction, exactly with: decresed TAPSE<1,5 cm (OR=0,500; 95% CI 0,323 – 0,775), S`<8,1 cm/s (OR=0,600; 95% CI 0,420 – 0,858) and IVV<5,9 cm/s (OR=0,250; 95% CI 0,117 – 0,534). As well we admitted significant decline of the velocities in earl and end diastole periods to compare with the results of the control group (E`= 12,11±1,22, A`= 4,56±0,92 cm/s (Р=0,009 and P=0.0002)), boost of the E/E` ratio – 7,96±2,33 (P=0.01) and decline of the RV IVRT up to 43,49±6,04 ms (P=0.017). Severe pulmonary regurgitation followed by high chances of the right ventricle systolic dysfunction development with TAPSE <1,5 cm (OR=0,500; 95% CI 0,323 – 0,775), S`<8,1 cm/s (OR=0,600; 95% CI 0,420 – 0,858) and IVV<5,9 cm/s (OR=0,250; 95% CI 0,117 – 0,534). As well we noticed high chances of the E/E`ratio > 6,0 in 1,5 times (95% CI 1,072 – 1,903) and decreased E` <12,2 cm/s (OR=0,200; 95% CI 0,083 – 0,481). Conclusions: Apart of clinical symptoms of the heart failure in children with tetralogy of Fallot after surgical correction markers of the right ventricle myocardial dysfunction are presented by indices of myocardial velocities, received during tissue doppler in different phases of the heart cycle.

Introduction and aim. Minor heart anomalies (MHA) are the visceral form of connective tissue dysplasia (CTD) that lead to a deterioration in both systolic and diastolic function of the left ventricle (LV). Information about functional state of the myocardium of the right ventricle (RV) of patients with MHA is not available widely. The aim of the study is to evaluate the frequency of occurrence of different types of MHA and features of intracardiac hemodynamic using Tissue Doppler (TD) examination of patients with CTD. Materials and methods. Total were surveyed 1240 people, of which were selected 67 patients with SHD and control group of 27 healthy persons (average age 30.1±4.0 years). Evaluation of systolic and diastolic function of LV and RV was carried out based on results of pulse-wave tissue Doppler of lateral and medial parts of the mitral fibrous annulus (MFAlat, MFFm) and tricuspid fibrous annulus (TEA), including the calculation of the index Tei. Results and discussion. The incidence of SHD was 23 %. Patients of first and second groups both have significantly higher Tei index MFAlat, MFFm and TFA, and at the same time the maximum values of Tei index were observed of patients with multiple MHA (0.50±0.09; 0.56±0.08; 0.49±0.10 standard units respectively). Conclusions. Evaluation of central hemodynamics using TD is very useful to identify disorders of myocardial performance of both the left and right ventricle. Increased Tei index is an early marker of diastolic dysfunction of both ventricles.
