Genetic Analysis of Heterotaxy in a Consanguineous Cohort.

Heterotaxy (HTX) is a group of clinical conditions with a shared pathology of dislocation of one or more organs along the left-right axis. The etiology of HTX is tremendously heterogeneous spanning environmental factors, chromosomal aberrations, mono/oligogenic variants, and complex inheritance. However, in the vast majority of cases, the etiology of HTX remains elusive.

Toward allogenizing a xenograft: Xenogeneic cardiac scaffolds recellularized with human-induced pluripotent stem cells do not activate human naïve neutrophils.

The limited availability of human donor organs suitable for transplantation has resulted in ever-increasing patient waiting lists globally. Xenotransplantation is considered a potential option, but is yet to reach clinical practice. Although remarkable progress has been made in overcoming immunological rejection, issues with functionality are still to be resolved.

Giant Iatrogenic Pseudoaneurysm of Right Pulmonary Artery Compressing the Left Atrium.

We describe a case of giant pseudoaneurysm of the right pulmonary artery compressing the left atrium after percutaneous pulmonary valve implantation and right pulmonary artery dilatation. Such a complication mimicking an intracavity left atrial mass and treated successfully by stent placement has never, to the best of our knowledge, been reported. ().

Acute and midterm outcomes of the post-approval MELODY Registry: a multicentre registry of transcatheter pulmonary valve implantation.

Aims: The post-approval MELODY Registry aimed to obtain multicentre registry data after transcatheter pulmonary valve implantation (TPVI) with the Melody™ valve (Medtronic plc.) in a large-scale cohort of patients with congenital heart disease (CHD).

Methods And Results: Retrospective analysis of multicentre registry data after TPVI with the Melody™ valve.

Data on hypoxia-induced VEGF, leptin and NF-kB p65 expression.

The data set presented here is associated with the article "Intracellular calcium and NF-B regulate hypoxia-induced leptin, VEGF, IL-6 and adiponectin secretion in human adipocytes" (Al-Anazi et al., 2018). Data illustrate hypoxia-induced VEGF and leptin expression in human adipocytes treated with the calcium chelator BAPTA-AM (1 µM).

Intracellular calcium and NF-B regulate hypoxia-induced leptin, VEGF, IL-6 and adiponectin secretion in human adipocytes.

Aims: Hypoxia-induced adipokine release has been attributed mainly to HIF-1α. Here we investigate the role of intracellular calcium and NF-kB in the hypoxia-dependent release of leptin, VEGF, IL-6 and the hypoxia-induced inhibition of adiponectin release in human adipocytes.

Main Methods: We used intracellular calcium imaging to compare calcium status in preadipocytes and in adipocytes.

Guidelines for the secondary prevention of rheumatic heart disease: Endorsed by Saudi Pediatric Infectious Diseases Society (SPIDS).

Rheumatic fever is a rare yet serious condition develop as a consequence of throat infection caused by It is the leading cause for rheumatic heart disease. Rheumatic heart disease is a worldwide public health concern. It is a chronic condition that results in carditis, irreversible valve damage and heart failure in children and young adults living in low-income countries.

Progression of matrixin and cardiokine expression patterns in an ovine model of heart failure and recovery.

Background: The molecular mechanisms underlying the geometrical changes of the left ventricle during the progression to heart failure and recovery are not well defined.

Objective: Here we investigate the involvement of matrixins and cardiokines in an ovine model of pressure-induced left ventricular failure (LVF).

Methods: Fifteen sheep underwent supracoronary aortic banding with an inflatable cuff.

Safety of transcatheter patent ductus arteriosus closure in small weight infants.

Background: Patent ductus arteriosus (PDA) is a frequent congenital heart disease. Its transcatheter closure has become the treatment of choice in children and adults. However, the device closure of PDA in children with low weight is still challenging with high rate of complications.
