In order to prevent children morbidity and mortality 116 children aged from 6 months to 5 years from 2 risk groups (1 -with bronchialpulmonary dysplasia and 2 -with congenital heart defects) were vaccinated with pneumococcal 7-valent conjugated vaccine in 2011 at the expense of municipal budget. Among 116 children from both groups 16 (14%) have had community-acquired pneumonia, which is 22 times higher than in general children population in this region. Dynamic 1-year follow-up showed significant decrease of community-acquired pneumonia prevalence in risk groups: from 16/116 (14%) to 1/75 (1%) (p = 0,006). There were no cases of invasive pneumococcal infections among vaccinated children and in 87,5% of them the general morbidity decreased. The frequency of moderate general post-vaccinal reactions was 1,8%, topical reactions -0,9%. There were no other side effects during post-vaccinal period. Thereafter, the vaccination against pneumococcal infection performed in Novosibirsk in children with risk of fatal complications showed high efficacy and safety of the used vaccine.
<p><strong>Aim:</strong> The paper focuses on assessment of the late results and causes of complications when repairing coarctation with distal aortic arch hypoplasia.<br /><strong>Methods:</strong> This prospective randomized study included 54 patients who underwent repair of coarctation of the aorta. All patients were divided in 2 groups depending on the correction type: reconstruction using the modified reverse left subclavian artery flap plasty (Group I, 27 pts) or extended end-to-end anastomosis (Group II, 27 pts).<br /><strong>Results:</strong> A postoperative follow-up period was 26 (21;31) months. Recoarctation of the aorta during long-term follow-up was found in 1 patient (3.84%) in Group I and in 2 patients (7.7%) in Group II (p=0.5). Two patients in the Group I (7.7%) and 8 patients in the Group II (30.8%) had arterial hypertension (p=0.03).<br /><strong>Conclusion:</strong> With modern types of surgical correction used, the anastomotic area tended to proportionally grow in different segments of the aortic arch and did not influence the postoperative complications rate. Endocardial fibroelastosis and ascending aortic wall rigidity could be considered as predictors of arterial hypertension in the late period after coarctation repair in infants. Low body weight before surgery is a factor of aortic recoarctation development in the late postoperative period. Arterial hypertension persistence depends on the correction type. One-stage reconstruction of the distal aortic arch allows for reducing the rate of arterial hypertension from 30.8% to 7.7%. Despite a range of complications in the late postoperative period, the infants’ quality of life was not affected and was high in both groups.</p>
The Ross procedure is thought of as an attractive option for aortic valve replacement in children and adolescents. We reviewed the basic and latest surgical criteria for graft selection in pediatric population who underwent the Ross procedure. Some positive and negative sides of various grafts in the aortic and lung positions are described. The tendencies and follow-up results of homograft growth proportional to somatic growth of patients are also analyzed.
Aim To compare the effects of continuous regional perfusion methods for infant aortic arch repair on the incidence of acute renal dysfunction and mortality in the early postoperative period.Methods A total of 121 infants who underwent aortic arch reconstruction in the period from June 2007 to December 2017 were included in the study. Patients were 1:1 propensity score matched using the nearest-neighbor methodology. Sixty-two patients (median age 14 (interquartile range (IQR) [8; 23]) days) were selected for the retrospective analysis and divided in two groups: those who underwent repair with selective antegrade cerebral perfusion (SACP) (SACP group, 31 patients) at 23–26°C and those who received whole brain perfusion and additional lower body perfusion (double arterial cannulation (DAC) group, 31 patients) at 28–32°C.Results In-hospital mortality was 3.2% in the DAC group (3.2%) and 12.8% in the SACP group, respectively (p = 0.03). More patients from the SACP group required an open chest after operation (p = 0.013). Patients from the DAC group had shorter open chest duration (p = 0.002) and shorter length of stay in the intensive care unit (ICU) (p = 0.035). There were no differences in the need for renal replacement therapy (p = 0.20) and rate of creatinine level progression during the first three postoperative days between the groups (p = 0.53). The body mass of less than 2 kilos predisposes patients to the onset of acute renal dysfunction (p = 0.013), which was found to be a predictor of early mortality (p = 0.038).Conclusion Lower body perfusion reported similar results to SACP in terms of the onset of acute renal dysfunction, but was superior in terms of lower mortality and shorter lengths of stay in the ICU.
Highlights. The geometry of the left atrium and the growth of the left heart after correction of total anomalous pulmonary venous connection are evaluated for the first time.Aim. To assess the morphological and functional characteristics of the left heart after correction of total anomalous pulmonary venous connection.Methods. 40 patients referred to the correction of total anomalous pulmonary venous connection were enrolled in a pilot, two-center, simple, blind, prospective randomized study. Patients were assigned to the sutureless repair group (n = 20) and conventional repair group (n = 20).Results. In the early postoperative period, the indexed left atrial volume in the group of sutureless repair was 15 (13.65; 17.25) versus 12.85 (10.95; 15.15) in the group of conventional repair, p = 0.057. The end diastolic volume index in the sutureless repair group was 38 (28.5; 45), while in the conventional repair group - 37.1 (31; 47.75), p = 0.48. At the follow-up, the indexed left atrial volume in the group of sutureless repair was 37 (34.5; 38.9) versus 31 (23.6; 35) in the group of conventional repair, p = 0.01. The end diastolic volume index (EDVI) in the group of sutureless repair was 50 (43; 57), while in the group of conventional repair - 50.2 (28.8; 60.9), p = 0.49.Conclusion. The growth of the left atrium depended on the chosen technique for correcting total anomalous pulmonary venous connection and was higher in the group of sutureless repair (37) compared to the group of conventional repair (31). The proportionality of the growth of the left ventricle did not depend on the surgical technique and was equivalent in both groups.
<p><strong>Aim.</strong> To evaluate the results of vacuum therapy and closed irrigation drainage (CID) technique for the treatment of postoperative sternomediastinitis in infants<br /><strong>Methods.</strong> This single-institution retrospective study included 69 patients diagnosed with sternomediastinitis from 2008 to 2018. Patients were divided into two groups: those treated using vacuum-assisted closure therapy (VAC; n = 29) and those treated using CID (n = 40). After propensity score matching, a total of 25 infants were included in each group.<br /><strong>Results.</strong> Age, gender, weight, body surface area, Risk Adjustment for Congenital Heart Surgery score, cardiopulmonary bypass time and the frequency of open chest management were comparable between the two groups after propensity score matching. During hospital stay, no deaths were noted in the VAC group, whereas eight patients died in the CID group (32%; P = 0.004). The median durations of mechanical ventilation were 79 (28; 176) and 154 (24; 356) hours in the VAC and CID groups, respectively (P = 0.38). Moreover, eight patients in the VAC group (32%) were extubated early (P = 0.028). Re-mediastinitis occurred in 1 (4%) and 8 (32%) patients from the VAC and CID groups, respectively (P = 0.01). The multivariable regression analysis revealed that the CID technique was the only risk factor for re-mediastinitis (odds ratio, 13.9; 95% confidence interval, 1.2–152.5; P = 0.031). The median durations of hospital stay were 14 (10; 30) and 23 (18; 33) days in the VAC and CID groups, respectively (P = 0.045).<br /><strong>Conclusion.</strong> VAC therapy in patients with mediastinitis showed better outcomes than CID technique such as lower hospital mortality and re-mediastinitis rates.</p><p>Received 14 August 2019.

Over the past 40 years, various types of prostheses have been developed for right ventricular outflow tract reconstruction. However, conduit stenosis and insufficiency due to valve degeneration occur frequently, decreasing the lifetime of patients. Transcatheter stenting of conduits does not always give favorable results and can lead to severe pulmonary regurgitation. The novel method of percutaneous pulmonary valve implantation is a good alternative to the surgical intervention according to data on long-term survival and quality of life.
