Sufficient versus deficient rims during percutaneous closure of ostium secundum type atrial septal defect: A systematic review and meta-analysis.

Background: The aim of this meta-analysis was to compare the efficacy and adverse events of percutaneous occlusion among patients with sufficient and deficient rims.

Methods: A systematic review of all articles published in the Pubmed, MEDLINE and Google Scholar databases was performed. Odds ratio (OR) and 95% CI were used as a measure of effect of the combination of studies.

Tetralogy of Fallot Repair After Neonatal Right Ventricular Outflow Tract Stenting: Initial Multicenter Experience in Argentina.

Initial management of patients with tetralogy of Fallot, unfavorable anatomy, and reduced pulmonary blood flow is controversial and continues to be a clinical challenge. Pulmonary to systemic shunt anastomosis or primary correction in neonates and small infants is associated with higher morbimortality and increased number of reoperations. Initial right ventricle outflow tract stenting palliation has emerged as an attractive alternative.

Pulmonary Vascular Research Institute GoDeep: A meta-registry merging deep phenotyping datafrom international PH reference centers.

The Pulmonary Vascular Research Institute GoDeep meta-registry is a collaboration of pulmonary hypertension (PH) reference centers across the globe. Merging worldwide PH data in a central meta-registry to allow advanced analysis of the heterogeneity of PH and its groups/subgroups on a worldwide geographical, ethnical, and etiological landscape (ClinTrial. gov NCT05329714).

Magnetic resonance lymphangiography in group 1 paediatric pulmonary arterial hypertension.

Pulmonary hypertension could have thoracic lymphatic abnormalities caused by right ventricular failure. Since there is no description of such abnormalities, the purpose of this study was to investigate them with magnetic resonance. Prospective review magnetic resonance T2-weighted lymphangiography was performed between January 2017 and October 2019 through quantitative thoracic duct diameter, diameter index and qualitative lymphatic abnormalities types: 1 - little or none abnormalities, 2 - abnormalities in supraclavicular region, 3 - abnormalities extending into the mediastinum and 4 - abnormalities extending into the lung.

Efficacy of citrulline supplementation to decrease the risk of pulmonary hypertension after congenital heart disease surgery. A local experience.

Introduction: Pulmonary hypertension (PH) is a major cause of morbi-mortality among patients with congenital heart disease (CHD) and also a potentially severe complication after surgical repair. Oral citrulline, a precursor to NO synthesis, is safe and efficacious for decreasing the risk of postoperative PH. Objective:

Objetive: The aim of the present study was to investigate in pediatric patients the changes of plasma citrulline, arginine, homocysteine and nitric oxide (NO) metabolites and pulmonary artery pressures (PAP) pre-post cardiac surgery in order to describe our population status with regard to the risk of pulmonary hypertension and look for potential biomarkers for early detection and treatment.

Clinical findings in 32 patients with 22qll.2 microdeletion attended in the city of Córdoba, Argentina.

The 22q11.2 microdeletion is the most common deletion syndrome, with a prevalence of 1/4000-1/6000 among newborn infants and a wide phenotypic variability. The diagnosis of the 22q11.

Percutaneous closure of the patent ductus arteriosus using the Nit-Occlud PDA-R (reverse) device: initial experience reporting immediate and short-term results.

Purpose: To review the initial clinical outcomes of patent ductus arteriosus (PDA) closure using the new Nit-Occlud PDA-R device (NOPDA-R).

Materials And Methods: The NOPDA-R is a self-expandable, nitinol-made, premounted and cone-shaped device with two distinctive features: reverse reconfiguration of the distal disc and a peculiar "snare-like" release mechanism. From May to December 2010, 20 consecutive patients were included.

Systemic hypertension and transient ischemic attack in a 6-year-old girl with fibromuscular dysplasia treated with percutaneous angioplasty.

We describe a 6-year-old girl with arterial hypertension secondary to fibromuscular dysplasia with stenoses of both renal arteries and transient ischemic attack due to extracranial right internal carotid artery subtotal occlusion as well as left internal carotid artery stenosis. She was treated with percutaneous angioplasty of both renal and both carotid arteries.

Some components of the cardiac β-adrenergic system are altered in the chronic indeterminate form of experimental Trypanosoma cruzi infection.

The chronic indeterminate form of Trypanosoma cruzi infection could be the key to knowing which patients will develop chagasic myocardiopathy. Infected mice present a period in which cardiac functional and structural alterations are different from those described for acute or chronic phases. We studied some components of the cardiac β-adrenergic system in mouse hearts infected with T.

Clinical features of hypertrophic cardiomyopathy in the young.

Background: We analysed the experience with hypertrophic cardiomyopathy in two paediatric centres to establish the differences from older patients.

Methods: Out of 45 young patients seen from 1974 to 1999, we included 38. Criterions for exclusion were secondary forms, or association with severe congenital cardiac disease which could alter the outcome.

Mid-Term Results of Dual-Chamber Pacing in Children with Hypertrophic Obstructive Cardiomyopathy.

BACKGROUND: Permanent dual-chambered pacing (DDD) is an alternative to surgical treatment in patients with severe hypertrophic obstructive cardiomyopathy (HOCM) who do not have a satisfactory response to medical treatment. METHODS: Five children with severe HOCM still symptomatic despite medical treatment underwent permanent DDD pacing and were followed for 21 +/- 9.7 months.
