Article Abstract
This study evaluates coagulation profiles of single ventricle (SV) patients in relationship to liver function, hemodynamic variables and outcome. Twenty-six children with SV anatomy were included. Advanced coagulation profiles, invasive preoperative hemodynamic parameters and clinical course were retrospectively analyzed. Median (interquartile range) age and weight at the time of blood sampling was 25.5 (31) months and 10.5 (6.9) kg. Sixteen patients (16/26; 62%) showed decreased antithrombin and/or protein C (PC) and/or free protein S (PS) function and/or free PS antigen. Two patients showed abnormal activated PC resistance ratio due to heterozygous factor V Leiden mutation and 1 heterozygous prothrombin G20210A mutation. Group comparison (abnormal coagulation profile [group 1; n = 16] versus normal coagulation profile [group 2; n = 10]) showed longer postoperative hospitalization time ( = .04), longer postoperative catecholamine support ( = .01), a higher incidence of thromboembolic events ( = .04), and chylothoraxes ( = .007) in group 1. In 5 (31%) of 16 group 1 patients, thromboembolic complications occurred: cerebral stroke (n = 1), intestinal ischemia (n = 2), thrombus formation in inferior caval vein (n = 1), and pulmonary vein (n = 1). Abnormalities in coagulation parameters are common in SV patients. Coagulation abnormalities constitute a preoperative risk factor and affect postoperative course.

Retinoblastoma in Dandy-Walker Syndrome.

Dandy-Walker syndrome (DWS), also referred to as Dandy-Walker malformation, is a rare congenital developmental anomaly characterized by enlargement of the posterior fossa, dilatation of the fourth ventricle, and cerebellar hypoplasia with upward rotation. Retinoblastoma is the most common primary intraocular malignancy in children and typically presents in the pediatric age group, with leukocoria and strabismus being common early signs. Although DWS and retinoblastoma are individually rare, their simultaneous occurrence is exceptionally uncommon.

Background: Paediatric patients who underwent surgery for mitral regurgitation (MR) have a high risk of recurrence or death; however, no prediction tool has been developed to risk-stratify this challenging subpopulation.
Methods: In this multicentre cohort study, paediatric patients undergoing surgery for congenital MR in Shanghai Children's Medical Center in January 1st, 2009-December 31st, 2022 were included for analysis while those had a combination with infective endocarditis, anomalous left coronary artery from the pulmonary artery, rheumatic valvular disease, connective tissue disease, or single ventricle were excluded. A Cox regression model predictive of the primary outcome (a composite of mortality or mitral valve [MV] re-operation) was derived and converted to a point-based risk score.
Risk Stratification of Sudden Cardiac Death in Nonischemic Dilated Cardiomyopathy: Arrhythmogenic Substrate Assessment in Cardiac MRI.

Department of Magnetic Resonance Imaging, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Background MRI-derived arrhythmogenic substrate, including late gadolinium enhancement (LGE) and extracellular volume fraction (ECV), is indicative of sudden cardiac death (SCD) risk in nonischemic dilated cardiomyopathy (DCM). The relative prognostic value of LGE and ECV remains unclear. Purpose To evaluate the performance of LGE and T1 mapping in predicting SCD in patients with DCM and to explore clinical implementation.

Department of Paediatric Cardiac Surgery, Kinderspital and University Zurich, Zurich, Switzerland.
Objectives: Primary repair of the common arterial trunk is still burdened by high mortality rates. Because of the low incidence and complexity of common arterial trunk, evidence is limited to reports with small sample sizes, and issues such as the ideal surgical timing to address the primary repair are still debated. We performed a systematic review and meta-analysis to estimate the pooled mortality, morbidity, and reoperation rates after common arterial trunk primary repair.
