Article Synopsis
  • - A notable number of patients with heterotaxy experience mismatched arrangements in their abdominal organs, lungs, and atrial structures, highlighting intriguing variations in the influence of ciliary and laterality genes on different body parts.
  • - Defects in these genes, which typically cause conditions like situs inversus and heterotaxy, can sometimes affect different sections of the heart separately, even when the overall arrangement of organs appears normal (situs solitus).
  • - Some patients with typical organ arrangement but with heart conditions like transposition of great arteries exhibit changes due to partial effects of laterality gene alterations, demonstrating the complex relationship between genetic defects and organ positioning.

To date, the role of NODAL in normal and abnormal L-R asymmetry has been well established. In a recent paper, mutations of this gene have been reported in heterotaxy but also in transposition with D- or L-ventricular loop. The effects of NODAL and other laterality genes can be recognized separately in all three cardiac segments: for topology and septation of the atria, for ventricular looping, and for spiralization and alignment of the great arteries.

Background: A peculiar subgroup of patients with partial or complete atrioventricular canal defect exhibits a spectrum of left-sided obstructions including right ventricular dominance and aortic coarctation. The association of atrioventricular canal defect with left-sided obstructions is found in several genetic syndromes; however, the molecular basis of nonsyndromic atrioventricular canal defect with aortic coarctation is still poorly understood. Although some candidate genes for nonsyndromic atrioventricular canal defect are known, a complex oligogenic inheritance determined in some cases by the co-occurrence of multiple variants has also been hypothesized.

Clinical features of 22q11.2 microdeletion syndrome (22q11.2DS) are highly variable between affected individuals and frequently include a subset of conotruncal and aortic arch anomalies.

Article Synopsis
  • Sotos syndrome is a genetic condition marked by traits like overgrowth, advanced bone age, and learning difficulties, mainly caused by genetic mutations in a gene on chromosome 5q35.
  • The study examined 45 patients with Sotos syndrome and found that about 60% had heart defects, with the most common issues being septal defects and other vascular anomalies.
  • The prevalence of heart defects in these patients was higher than previously reported in literature, highlighting the need for thorough heart evaluations in individuals with Sotos syndrome.

We tested whether the brain and kidney respond differently to cardiopulmonary bypass (CPB) and to changes in perfusion conditions during CPB. Therefore, in ovine CPB, we assessed regional cerebral oxygen saturation (rSO ) by near-infrared spectroscopy and renal cortical and medullary tissue oxygen tension (PO ), and, in some protocols, brain tissue PO , by phosphorescence lifetime oximetry. During CPB, rSO correlated with mixed venous SO (r = 0.

Background And Objective: Congenital heart defects (CHD) represent the most frequent human birth defects, occurring in almost 1% of all live newborns. Understanding the effects of gender in the prevalence of CHD has a key role in defining personalized prevention, disease identification, prognosis definition and individualized therapeutic strategies. Recently, the attempt to achieve a holistic approach to patients with CHD cannot be separated from accounting for existing gender differences.

Article Synopsis
  • The 22q11.2 deletion syndrome is a genetic condition that's common and often linked to heart problems. Prenatal testing for this condition is becoming more common.
  • This study looked at how well babies do when they are diagnosed before they are born versus after they are born.
  • They found that, overall, the chance of dying in the first year didn't change much between those diagnosed early or late, but serious heart problems and when the baby was born affected the results.

Congenital heart disease (CHD) affecting the conotruncal region of the heart, occurs in 40-50% of patients with 22q11.2 deletion syndrome (22q11.2DS).

Background: Intraoperative inflammation may contribute to postoperative neurocognitive disorders after cardiac surgery requiring cardiopulmonary bypass (CPB). However, the relative contributions of general anesthesia (GA), surgical site injury, and CPB are unclear.

Methods: In adult female sheep, we investigated (1) the temporal profile of proinflammatory and anti-inflammatory cytokines and (2) the extent of microglia activation across major cerebral cortical regions during GA and surgical trauma with and without CPB (N = 5/group).

Chromosome 9p deletion syndrome is a rare autosomal dominant disorder presenting with a broad spectrum of clinical features, including congenital heart defects (CHDs). To date, studies focused on a deep characterization of cardiac phenotype and function associated with this condition are lacking. We conducted a multicentric prospective observational study on a cohort of 10 patients with a molecular diagnosis of 9p deletion syndrome, providing a complete cardiological assessment through conventional echocardiography and tissue Doppler imaging echo modality.

Deleterious variants of DYNC2H1 gene are associated with a wide spectrum of skeletal ciliopathies (SC). We used targeted parallel sequencing to analyze 25 molecularly unsolved families with different SCs. Deleterious DYNC2H1 variants were found in six sporadic patients and two monozygotic (MZ) twins.

Article Synopsis
  • * Researchers evaluated AR dimensions in 74 patients, finding that 32.4% exhibited ARD, with a notable correlation between ARD severity and skeletal/connective tissue disorders.
  • * The study concluded that isolated ARD is prevalent in this population, and regular cardiac monitoring is essential for improving long-term health outcomes, despite unclear risk factors and complications.

This review examines and discusses the morphology and embryology of two main groups of conotruncal cardiac malformations: (a) transposition of the great arteries (complete transposition and incomplete/partial transposition namely double outlet right ventricle), and (b) aortic dextroposition defects (tetralogy of Fallot and Eisenmenger malformation). In both groups, persistent truncus arteriosus was included because maldevelopment of the neural crest cell supply to the outflow tract, contributing to the production of the persistent truncus arteriosus, is shared by both groups of malformations. The potentially important role of the proximal conal cushions in the rotatory sequence of the conotruncus is emphasized.

Aim: Cardiac surgery requiring cardiopulmonary bypass (CPB) can result in renal and cerebral injury. Intraoperative tissue hypoxia could contribute to such organ injury. Hypothermia, however, may alleviate organ hypoxia.

Congenital heart diseases represent one of the hallmarks of 22q11.2 deletion syndrome. In particular, conotruncal heart defects are the most frequent cardiac malformations and are often associated with other specific additional cardiovascular anomalies.
