Platelet Aggregation Before Aspirin Initiation in Pediatric Patients With Congenital Heart Disease at High Risk of Thrombosis.

Background: Aspirin following unfractionated heparin is the most common anticoagulation strategy for pediatric patients who experienced cardiac surgery at high risk of thrombosis. The platelet aggregation test is the golden method to evaluate the aspirin effect on platelet function. However, the platelet aggregation basal status before postoperative aspirin initiation and the related clinical influencing factors hasn't been investigated systemically in this population.

Aortopulmonary Collateral Arteries in Noncyanotic Congenital Heart Disease.

Development of major aortopulmonary collateral arteries are strongly associated with cyanotic congenital heart disease. However, they have rarely been reported in noncyanotic congenital heart disease. We report a rare case of a newborn originally diagnosed with an atrial septal defect, a ventricular septal defect, and pulmonary arterial hypertension who underwent complete repair.

Vasopressin in Vasodilatory Shock for Both Left and Right Heart Anomalous Pediatric Patients After Cardiac Surgery.

Although the use of vasopressin has become commonplace in pediatric patients with vasodilatory shock after cardiac surgery, its efficacy and hemodynamic effects have not been systematically documented. Furthermore, previous studies were mainly limited patients with left heart anomalies. To date, the use of vasopressin in patients with right heart anomalies has not yet been reported.

NEXN inhibits GATA4 and leads to atrial septal defects in mice and humans.

Aims: Cardiac structural genes have been implicated as causative factors for congenital heart diseases (CHDs). NEXN is an F-actin binding protein and previously identified as a disease gene causing cardiomyopathies. Whether NEXN contributes to CHDs aetiologically remains unknown.
