A miniature marvel: left main coronary stenting in a tiny newborn after left coronary artery from the pulmonary artery surgery.

Anomalous left coronary artery from the pulmonary artery is a congenital coronary artery anomaly comprising 0.5% of all CHDs. Stenosis in the left coronary artery implanted in the sinus valsalva is one of the complications of surgical repair.

Situs inversus with dextrocardia and transposition of great arteries.

Transposition of the great arteries with left ventricle outflow tract obstruction in combination with situs inversus totalis and dextrocardia is a very rare anomaly and carries high morbidity and mortality. Only few cases have been reported with this anomaly. We describe a 21-day of infant girl with transposition of the great arteries and mirror image dextrocardia and pulmonary stenosis who underwent successful neonatal arterial switch operation and left ventricle outflow tract obstruction resection following PDA stent implantation.

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.

Biventricular repair in an infant with transposition of the great arteries and straddling of the tricuspid valve.

Biventricular repair is challenging in patients with transposition of the great arteries and straddling of the atrioventricular valves. Biventricular repair is the preferred option because of its anatomical and physiological advantages. However, in cases where biventricular repair carries operative risks that are too high or cases with unsuitable intracardiac anatomy, univentricular heart repair may have to be chosen.

Predictors of prolonged pleural effusion after Fontan operation.

Prolonged pleural effusion is a fairly common condition which has considerable impact on complicated and longer hospital stays after Fontan surgery. Identifying the patient population prone to have pleural effusions is still seeking for an answer. This study is to determine the variables that may predict prolonged pleural effusion according to the data of 69 patients who underwent Fontan operation between June 2018 and December 2020 and survived to date.

Clinical Characteristics and Mid-term Follow-up in Children with Isolated Complete Atrioventricular Block.

Background: Isolated complete atrioventricular block is a rare disease often associated with maternal autoantibodies. This study aimed to present the midterm data of patients at our clinic diagnosed with isolated complete atrioventricular block.

Methods: We evaluated 108 patients diagnosed with isolated complete atrioventricular block.

Isolated coarctation repair through a left thoracotomy in children.

Introduction: Isolated aortic coarctation performed through a left thoracotomy resection and end-to-end anastomosis results in low mortality and morbidity rates. Recoarctation and late hypertension are among the most important complications after such repairs. In this study, we reviewed the results of children who underwent left-side thoracotomy to correct an isolated aortic coarctation.

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.

Single-center experience with routine clinical use of 3D technologies in surgical planning for pediatric patients with complex congenital heart disease.

Purpose: This study was planned to assess the application of three-dimensional (3D) cardiac modeling in preoperative evaluation for complex congenital heart surgeries.

Methods: From July 2015 to September 2019, 18 children diagnosed with complex congenital heart diseases (CHDs) were enrolled in this study (double outlet right ventricle in nine patients, complex types of transposition of the great arteries in six patients, congenitally corrected transposition of the great arteries in two patients, and univentricular heart in one patient). The patients' age ranged from 7 months to 19 years (median age, 14 months).

A Quite Rare Association: Levo-Malposition of the Great Arteries with Left Juxtaposition of the Atrial Appendages in "Double Outlet Right Ventricle".

Although many anatomical variations may be encountered in children with double outlet right ventricle, coexistence of levo-malposed great vessels and left juxtaposed atrial appendages is uncommonly observed. This case report underlines the rarity of this anatomical combination and its clinical significance along with the surgical management in an infant.
