Use of ivabradine in children with junctional ectopic tachycardia after pediatric cardiac surgery; two-centre experience.

Introduction: Although amiodarone is traditionally used in the treatment of postoperative junctional ectopic tachycardia (JET), the search for new treatments is ongoing. We present our experience with ivabradine at two medical centers.

Materials And Methods: Between January 2022 and January 2023, patients who developed JET after pediatric cardiac surgery were prospectively followed up and documented.

Management of patients developing axillary pseudoaneursym after ductal stenting: Report of three cases.

Pseudoaneurysms develop as a result of disruption of the arterial wall due to trauma or iatrogenic reasons such as catheterization, and it is important due to the high risk of bleeding and rupture. Until recently, the main treatment of pseudoaneurysms was surgical repair. However, in recent years, minimally invasive methods such as ultrasound-guided compression and percutaneous thrombin injection have been used more frequently.

Assessment of the frequency and risk factors of gastrointestinal bleeding after cardiopulmonary bypass in paediatric cases.

Introduction And Aim: Gastrointestinal bleeding is a potential complication in paediatric patients undergoing cardiopulmonary bypass, as it develops secondary to low gastrointestinal perfusion. This study aimed to examine the incidence of gastrointestinal bleeding and identify its risk factors in these patients.

Method: This retrospective study was undertaken to examine the demographic features, clinical findings, and operative data of paediatric patients under years old who had undergone congenital heart surgery with cardiopulmonary bypass between November 1, 2021, and November 1, 2023.

Impact of high-flow nasal oxygen therapy on postoperative atelectasis and reintubation rate after paediatric cardiac surgery.

Introduction: Airway problems emerging after congenital cardiac surgery operations may have an impact on mortality and morbidity. Recently, to improve alveolar gas exchange and reduce respiratory effort, high-flow nasal cannula (HFNC) has started to be used in paediatric cases. This study aimed to evaluate the potential effects of high-flow nasal oxygen therapy on postoperative atelectasis development and reintubation rate in paediatric cardiac surgery patients.

Myocardial infarction and narrowed peripheral arterial vessels secondary to generalised arterial calcification syndrome in a two-month-old girl.

Generalised arterial calcification of infancy, an autosomal recessive disorder characterised by abnormal calcification of medium and large-sized arteries, represents a rare cause of dilated cardiomyopathy. We present the case of a two-month-old girl diagnosed posthumously with dilated cardiomyopathy. Studies suggest that early initiation of treatment can improve prognosis in generalised arterial calcification of infancy, so clinicians should be alert to the condition, especially in patients displaying generalised narrowing of medium and large-sized arteries.

Results of a hybrid approach for high risk term newborn patients with interrupted aortic arch (IAA) with left ventricular outflow tract obstruction.

This study aims to share the results of critically ill newborn cases with interrupted aortic arch (IAA) and Left ventricular outflow tract (LVOT) obstruction (LVOTO) who underwent the hybrid approach, which consists of bilateral pulmonary artery banding and/or patent ductus arteriosus stenting, as first-line treatment. This retrospective study includes the results of high-risk term newborns whom we applied a hybrid approach due to IAA and LVOTO in our clinic between January 1, 2021 and December 31, 2021. The demographic characteristics, hybrid approach methods and results of the cases were evaluated.

One-Year Follow-Up Results of MIS-C Patients with Coronary Artery Involvement: A Multi-center Study.

Multisystem inflammatory syndrome (MIS-C) in children is a rare complication of SARS-CoV-2 infection. Knowing the course of the affected or unaffected coronary arteries in the patients under follow-up is important in terms of defining the long-term prognosis of the disease and determining the follow-up plan. This is a multicenter and retrospective study.

Factors Predicting Early Major Adverse Events in the Intensive Care Unit After Successful Cardiac Surgery for Congenital Heart Disease in Full-Term Neonates.

Objective: In this study, we aimed to evaluate the factors affecting major adverse event (MAE) development after full-term neonatal cardiac surgery.

Methods: This study was conducted retrospectively on newborns who underwent congenital heart surgery between June 1, 2020, and June 1, 2022. MAE was defined as the presence of at least one of the following: cardiac arrest, unplanned reoperation, emergency chest opening, admission to the advanced life support system, and death.

A unique bizarre subtype of mixed total anomalous pulmonary venous connection.

Mixed total anomalous pulmonary venous connection is a rare CHD with a wide variation in pulmonary venous anatomy and drainage. We present a ten-day-old newborn with a rare bizarre subtype of mixed total anomalous pulmonary venous connection.

Comparison of the effects of conventional method and primary sutureless techniques on early postoperative rhythm problems in patients with total abnormal pulmonary venous return anomaly.

Background: Total abnormal pulmonary venous return anomaly is a CHD characterised by abnormal pulmonary venous flow directed to the right atrium. In this study, we aimed to compare the effects of these techniques on early rhythm problems in total abnormal pulmonary venous return anomaly cases operated with conventional or primary sutureless techniques.

Method: Seventy consecutive cases (median age 1 month, median weight 4 kg) who underwent total abnormal pulmonary venous return anomaly repair with conventional or primary sutureless technique between May 1 2020 and May 1 2022 were evaluated.

Evaluation of perfusion index and left ventricular output changes in low cardiac output syndrome after arterial switch operation.

Introduction: Transposition of great arteries is one of newborns' most common cyanotic CHDs, and its treatment is arterial switch operation in the first days of life. Low cardiac output syndrome may develop in the early postoperative period. In this study, we evaluated perfusion index and left ventricular output blood flow changes in patients who underwent arterial switch operation and developed low cardiac output syndrome.

The comparison of three different acute kidney injury classification systems after congenital heart surgery.

Background: We aimed to compare the frequency of acute kidney injury (AKI) and its effects on mortality and morbidity with different classification systems in pediatric patients who had surgery under cardiopulmonary bypass for congenital heart disease.

Methods: This study included children younger than 18 years old who were followed up in the pediatric cardiac intensive care unit between September 1 and December 1, 2020, after congenital heart surgery with cardiopulmonary bypass. Each case was categorized postoperatively in terms of AKI using Pediatric-Modified Risk, Injury, Failure, Loss, and End-Stage (pRIFLE), Acute Kidney Injury Network (AKIN), and Kidney Disease: Improving Global Outcomes (KDIGO).

Spectrum of Genetic Variants in a Cohort of 37 Laterality Defect Cases.

Laterality defects are defined by the perturbed left-right arrangement of organs in the body, occurring in a syndromal or isolated fashion. In humans, primary ciliary dyskinesia (PCD) is a frequent underlying condition of defective left-right patterning, where ciliary motility defects also result in reduced airway clearance, frequent respiratory infections, and infertility. Non-motile cilia dysfunction and dysfunction of non-ciliary genes can also result in disturbances of the left-right body axis.

Can we predict risk for cardiac involvement in paediatric inflammatory multi-system syndrome?

Introduction: Increasing recognition of paediatric inflammatory multi-system syndrome is a cause of concern. This study aimed to evaluate children with paediatric inflammatory multi-system syndrome and compare the clinical and laboratory features of children with and without cardiac involvement.

Material And Methods: We conducted a prospective single-centre study including 57 (male 37, 65%) patients with paediatric inflammatory multi-system syndrome at a tertiary care hospital between November, 2020 and March, 2021.

Comparison of echocardiography and 320-row multidetector computed tomography for the diagnosis of congenital heart disease in children.

Introduction: Echocardiography (echo) is the primary non-invasive imaging modality for the assessment of congenital heart disease (CHD). Computed tomography angiography (CTA) also has potential to examine the anatomy of complex heart anomalies as well as extracardiac involvement.

Objectives: The aim of this study is to determine the impact of new CTA technology in the diagnosis of CHD and to compare echo and CTA in terms of diagnostic accuracy.

Transcatheter Closure of Aortopulmonary Window in Infants with Amplatzer Duct Occluder-I.

Aortopulmonary window (APW) is a septation defect between the ascending aorta and main pulmonary artery, and it accounts for 0.2-0.6% of all congenital heart diseases.

The Use of Chronic Total Occlusion (CTO) Wires for Perforation of Atretic Pulmonary Valve; Two Centers Experience.

Pulmonary valve atresia with intact ventricular septum (PA-IVS) can be treated either surgically or transcatheterly for eligible patients. Perforation of pulmonary valves using chronic total occlusion (CTO) guidewires has been reported as an alternative to radiofrequency (RF) perforation. We sought to report our experience with CTO guidewires for perforation of atretic pulmonary valves and subsequent balloon dilatation (with or without patent ductus arteriosus stenting) in patients with PA-IVS from two centers.
