Clinical and Hemodynamic Outcomes with Enalapril Orodispersible Minitablets in Young Children with Heart Failure Due to Congenital Heart Disease.

: The angiotensin-converting enzyme inhibitor (ACEI) enalapril is often administered to infants and young children with heart failure (HF) in various dosing regimens and formulations not adapted for their age. : This prospective, two-center, open-label 8-week study evaluated an age-appropriate formulation of orodispersible minitablets (ODMTs) of enalapril (0.25 mg and 1 mg) in children aged 0 to 6 years with HF due to congenital heart disease.

Factors Associated with the Antibiotic Treatment of Children Hospitalized for COVID-19 during the Lockdown in Serbia.

Unselective use of antibiotics to treat children with COVID-19 is one of the major issues during the pandemic in Serbia. Thus far, there has been no evidence about the predictors of multiple antibiotic use in the treatment of children with COVID-19. The purpose of this study was to assess the prevalence of antibiotic use, as well as to examine demographic and clinical factors associated with a greater number of antibiotics and with a longer antibiotic treatment administered to hospitalized children with COVID-19 during the lockdown in Serbia.

Background: Acute myocarditis (AM) is defined as inflammation of the myocardium. The aim of our study is a comparative analysis of the differences between AM related and unrelated to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Methods: The retrospective study included children with AM treated from January 2018 to November 2020.

A Scimitar Syndrome Variant Associated with Critical Aortic Coarctation in a Newborn.

BACKGROUND Scimitar syndrome (SCS) is a rare congenital cardiopulmonary malformation, characterized by anomalous pulmonary venous drainage from the right lung associated with aortopulmonary collateral arteries and pulmonary hypoplasia. The variant described in the case presented here, with total anomalous right pulmonary venous drainage into the superior and inferior vena cava, can be expected in 2% of patients with scimitar syndrome. To the best of our knowledge, the association between the variant of SCS and coarctation of aorta described in our patient has never been reported before in the literature.

Successful use of sirolimus for refractory atrial ectopic tachycardia in a child with cardiac rhabdomyoma.

Cardiac rhabdomyomas are common in tuberous sclerosis. We report a child who developed rhabdomyoma related arrhythmia refractory to antiarrhythmic drug therapy. Reversion of the atrial ectopic tachycardia was achieved with mammalian target of rapamycin pathway (mTOR) inhibitor sirolimus.

The Analysis of the Risk Factors in the Arterial Switch Operation for Treatment of D-Transposition of the Great Arteries in One Pediatric Cardiac Center in Serbia.

Introduction: The arterial "switch" operation has been the operation of choice for children born with D-transposition of the great arteries (D-TGA) for more than 30 years in countries with developed pediatric cardiac surgery program. After two decades of successful treatment of these children with the atrial "switch" corrections (Mustard or Senning operative techniques), the arterial "switch"operation (ASO) had been introduced as a routine technique in one pediatric cardiac center in Serbia.

Objective: The aim of this study was the analysis of the identified risk factors involved with the ASO in the preoperative, operative and postoperative period and their impact on the survival of the operated children.

The relationship between currently recommended ambulatory systolic blood pressure measures and left ventricular mass index in pediatric hypertension.

This study aims to explore the relationship between currently recommended ambulatory blood pressure (ABP) measures used to classify pediatric hypertension and left ventricular mass index (LVMI) in children with true ambulatory hypertension. We performed a cross-sectional survey among 94 children who were consecutively referred for suspected hypertension. The calculated ABP measures were average 24-h systolic blood pressure (24-h aSBP) and 24-h SBP load.

Balloon dilation and surgical valvotomy comparison in non-critical congenital aortic valve stenosis.

Percutaneous balloon aortic valvoplasty (BAV) and surgical aortic valvotomy (SAV) are palliative procedures in patients with non-critical congenital valve stenosis. The aim of the study was to evaluate long-term BAV and SAV results after up to 24 years of follow-up. From 1987 to 2013, 74 consecutive interventions were performed in patients with aortic stenosis, and 62 were included in the study (39 BAVs and 23 SAVs).

Predictive value of biochemical, echocardiographic and electrocardiographic markers in non-surviving and surviving asphyxiated full-term newborns.

Severe perinatal asphyxia can cause multiple organ dysfunction and early neonatal mortality. This prospective study was conducted at the Regional University Hospital Neonatology Center in Serbia. The aim of this study was to compare fullterm asphyxiated newborn infants (n=55) with (n=13) and without (n=42) mortality outcome and healthy full-term newborns (n=36) regarding biochemical (cardiac troponin I, creatine kinase (total and MB fraction) and C-reactive protein), echocardiographic (ejection fraction, fractional shortening, mitral regurgitation, significant tricuspid regurgitation, and patent ductus arteriosus) and electrocardiographic (ST segment elevation/depression, T wave inversion and corrected QT interval) markers of myocardial damage in order to assess their predictive value in the clinical outcome.

Mechanisms of Beta-Blockers Action in Patients with Heart Failure.

Patients with chronic heart failure have prolonged sympathetic stimulation and subsequent worsening of the failing heart function. Beta-blockers (non-selective, cardio-selective, and non-selective with ancillary properties) counteract the effects of prolonged sympathetic stimulation. Beta-blocker therapy results in the improvement of the left ventricular systolic and diastolic function, reversal remodeling, heart rate control, effective prevention of the malignant arrhythmias, and lowering of the both cardiac afterload and preload in patients with chronic heart failure.

Beta-Blockers (Carvedilol) in Children with Systemic Ventricle Systolic Dysfunction - Systematic Review and Meta-Analysis.

Background: Numerous prospective randomized clinical trials demonstrated favorable effect of beta-blockers in adults with chronic heart failure. However, effectiveness of beta blockers in pediatric patients with systemic ventricle systolic dysfunction was not recognized sufficiently. Limited number of pediatric patients might be the course of unrecognized carvediolol treatment benefit.

The role of biochemical markers as early indicators of cardiac damage and prognostic parameters of perinatal asphyxia.

Background/aim: In recent years, the focus of interest of the scientific community is the application of heart markers as early indicators and prognostic parameters of perinatal asphyxia (PA). The aim of this study was to evaluate the significance of clinical application of heart markers in term newborns with perinatal asphyxia.

Methods: During a 3-year period we analyzed 91 full-term newborns (55 with and 36 without perinatal asphyxia).

Blood pressure variability and left ventricular mass index in children.

Clinical implications of blood pressure variability (BPV) on subclinical organ damage in children are unknown. The authors sought to explore the potential utility of two newly derived BPV indices: weighted standard deviation (wBPSD) and real average variability (ARV), as well as two standard ambulatory blood pressure indices: average 24-hour systolic blood pressure (SBP) and 24-hour SBP load, to identify children at high risk for left ventricular (LV) hypertrophy (LVH). The study group consisted of 67 consecutive children who were referred to our institution for evaluation of suspected hypertension.
