ABSTRACT Background Multisystem inflammatory syndrome in children (MIS‐C) is associated with cardiac involvement 67%–80% of cases. Cardiac symptoms often normalize rapidly after treatment, but few studies are available on the long‐term effects. Methods Our study evaluated functions 40 patients diagnosed MIS‐C between August 2021 and November 2022. Conventional echocardiography (ECHO), electrocardiography (ECG), speckle tracking (STE), MR were performed at time diagnosis 3‐nd 6‐month...

Objective: To assess the feasibility of 12-lead electrocardiographic (ECG) measures such as P wave dispersion (PWd), QT interval, (QTd), Tp-e Tp-e/QT and Tp-e/QTc ratio in predicting poor outcome patients diagnosed with sepsis pediatric intensive care unit (PICU). Methods: Ninety-three sepsis, severe or septic shock 103 age- sex-matched healthy children were enrolled into study. PWd, QTd, interval Tp-e/QT, ratios obtained from a electrocardiogram. Results: significantly higher compared...

Transcatheter closure of medium and large ventricular septal defects (VSDs) in young children is limited due to the use over-sized devices that can cause hemodynamic instability arrhythmia. In this study, we aimed retrospectively evaluate safety efficacy device mid-term weighing less than 10 kg whose transcatheter VSD was closed only with Konar-MFO device.Among 70 between January 2018 2023, 23 patients were included study. Retrospectively, medical records all reviewed.The mean age 7.3...

Radiofrequency (RF) catheter ablation in the septal arrhythmia substrates has an increased risk of irreversible atrioventricular block. Despite its safety profile, several studies reported a lower acute success rate and higher recurrence with cryoablation accessory pathways (APs) when compared to RF ablation. The aim this study was assess efficacy right APs using electroanatomical mapping system guidance.A total 43 consecutive patients (13.2 ± 5.5 years) underwent for APs. EnSite (St. Jude...

Background Mean platelet volume (MPV), platecrit, and distribution width (PDW) are markers of activation. Previous studies have found that activation occurs in patients with pulmonary arterial hypertension. Platelet indices including MPV, PDW, platecrit not been studied children congenital heart disease associated hypertension (APAH-CHD) who survived those died. Objective The objective this study to investigate the value clinical hemodynamic indicators predicting severity survival APAH-CHD....

Postnatal closure of the ductus arteriosus is a complicated two-phase process involving functional and structural changes. So far, precise mechanisms regulating this are not fully understood. A growing body evidence from recent studies suggests that platelets play key role in inflammatory processes including ductal via interaction with endothelial cells. The aim study to assess whether relationship exists between occurrence and/or hemodynamically significant (HSDA) platelet parameters...

Summary Aim We analysed 25 children with 21‐hydroxylase deficiency who received glucocorticoid and/or mineralocorticoid treatment for at least 12 months to determine the effects of disease and its on vascular structures ventricular function. Methods Twenty‐five patients 21‐hydroxylase‐deficient congenital adrenal hyperplasia ( CAH ) control subjects were enrolled into this observational, cross‐sectional study. The investigated in terms fasting blood glucose insulin; serum lipid profile;...

Abstract In this multi-centre study, the mid- to long-term efficacy and safety of Amplatzer Piccolo Occluder in patent ductus arteriosus closure premature term infants as well children were discussed. Methods. Between 2016 2021, 645 patients, 152 whom less than 1 month old, underwent with device from five different centres Turkey. The median age patients was 2.2 years, mean narrowest point duct diameter 1.8 mm. Sixty-two weighed ≤ 1.5 kg, 90 1.5–3 follow-up 20.4 months. 396, closed by...

Introduction Device closure of perimembranous ventricular septal defects (pmVSD) is a successful off-label treatment alternative. We aim to report and compare the outcomes pmVSD in children weighing less than 10 kg using Amplatzer Duct Occluder II (ADOII) Konar-MF VSD (MFO) devices. Methods Retrospective clinical data review 52 with hemodynamically significant pmVSD, sent for transcatheter ADOII MFO, between January 2018 2023. Baseline, procedural, follow-up were compared according implanted...

Intravenous (IV) ferric iron (Fe)-carbohydrate complexes are used for treating Fe deficiency in children with iron-refractory iron-deficiency anemia (IRIDA). An optimal treatment has yet to be determined. There relatively little publications on the responsiveness IV therapy IRIDA.This study analyzed responses sucrose given 11 children, ranging age from 2 13 years (mean 4.8 years), who were unresponsive oral therapy.The hemoglobin and ferritin values (mean) of IRIDA 7.7 g/dL ng/mL at...
