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.

Successful ductal stent implantation for initial palliation in two patients with aortic atresia and interrupted aortic arch.

The coexistence of aortic valve atresia and interrupted aortic arch are an extremely rare condition. In this pathology, blood flow to the ascending aorta and coronary arteries should be provided through the ductus arteriosus or collaterals originating from the descending aorta. In rare cases where bilateral ductus arteriosus is present, they can provide circulation.

18F-fluorodeoxyglucose positron emission tomography/CT in the diagnosis of right-sided endocarditis in children and adults with infective endocarditis.

All procedures were performed using the EnSite Precision 3D mapping system (Abbott Laboratories, Abbott Park, Ill, USA) with a limited fluoroscopy approach.

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.

Is it possible to reduce radiation exposure during transcatheter atrial septal defect closure in children?

Objective: Cardiac catheterization continues to be a major source of radiation exposure for patients with congenital heart disease. As children are more prone to both deterministic and stochastic effects of radiation, every effort should be made to reduce radiation exposure. One way to reduce the radiation dose is to lower the pulse fluoroscopy rate.
