Balloon atrioseptostomy for transposition of the great arteries in Europe: characteristics and outcomes.

Introduction And Objectives: Balloon atrial septostomy (BAS) improves oxygenation in neonates with transposition of the great arteries (TGA) and restrictive foramen ovale. Currently, there is a global shortage of dedicated BAS catheters, while new unmarked catheters have recently become available at some European centers. This study aimed to characterize BAS outcomes using the currently available BAS catheters in Europe.

Covered Stent Correction for Sinus Venosus Atrial Septal Defects, an Emerging Alternative to Surgical Repair: Results of an International Registry.

Background: Covered stent correction for a sinus venosus atrial septal defect (SVASD) was first performed in 2009. This innovative approach was initially viewed as experimental and was reserved for highly selected patients with unusual anatomic variants. In 2016, increasing numbers of procedures began to be performed, and in several centers, it is now offered as a standard of care option alongside surgical repair.

Complete atrioventricular block after atrial flow regulator implantation in a 5 kg infant.

The atrial flow regulator is a new self-expandable double-disc fenestrated device providing a calibrated inter-atrial communication. Paediatric reports are scarce. We herein describe a case of complete atrioventricular block complicating the exemption use of an atrial flow regulator in a 5-kg infant with transposition of the great arteries, ventricular septal defect, and right ventricular outflow tract obstruction.

Single ventricle palliation in congenitally corrected transposition of the great arteries: An international multicenter study.

Background: Single ventricle palliation may be performed in patients with congenitally corrected transposition of the great arteries due to hypoplasia of 1 ventricle or anatomic complexity rendering biventricular repair unfeasible. There have been only a few small studies of the outcomes of single ventricle palliation in the setting of congenitally corrected transposition of the great arteries.

Methods: A multicenter, international, retrospective cohort study of patients with congenitally corrected transposition of the great arteries undergoing single ventricle palliation was conducted in 29 tertiary hospitals in 6 countries from 1990 to 2018.

Device Closure of Hemodynamically Significant Patent Ductus Arteriosus in Premature Infants.

The patent ductus arteriosus is a very common condition in preterm infants, and a hemodynamically significant patent ductus arteriosus increases morbidity and mortality in these vulnerable patients. However, despite numerous randomized controlled trials, there is no consensus regarding management. Medical therapy is typically offered as first-line treatment, although it yields limited success and carries the potential for severe adverse events.

Rescue one-stage hybrid perventricular and percutaneous device closure of multiple muscular ventricular septal defects using the new multifunctional occluder.

Data on the safety and efficiency of perventricular device closure of complex ventricular septal defects (VSDs) are scarce. We report successful one-stage combined hybrid perventricular and percutaneous closure of the muscular VSDs in a critically ill 4-kg infant, using the new multifunctional occluder.

Cognitive biases in pediatric cardiac care.

Medical practitioners are entrusted with the pivotal task of making optimal decisions in healthcare delivery. Despite rigorous training, our confidence in reasoning can fail when faced with pressures, uncertainties, urgencies, difficulties, and occasional errors. Day-to-day decisions rely on swift, intuitive cognitive processes known as heuristic or type 1 decision-making, which, while efficient in most scenarios, harbor inherent vulnerabilities leading to systematic errors.

Comparative analysis of left ventricle function and deformation imaging in short and long axis plane in cardiac magnetic resonance imaging.

Background: Advancements in cardiac imaging have revolutionized our understanding of ventricular contraction. While ejection fraction (EF) is still the gold standard parameter to assess left ventricle (LV) function, strain imaging (SI) has provided valuable insights into ventricular mechanics. The lack of an integrative method including SI parameters in a single, validated formula may limit its use.

Risk of infective endocarditis after hybrid melody mitral valve replacement in infants: the French experience.

Objectives: Surgical management of mitral valve disease is challenging in infants <1 year old. We aimed at reviewing the French experience with Melody mitral valve replacement in critically ill infants.

Methods: A retrospective cohort study reporting the French experience with Melody mitral valve replacement.

Bilateral ductal stenting in an infant with pulmonary atresia and ventricular septal defect, non-confluent pulmonary arteries, and bilateral arterial duct.

Pulmonary atresia with ventricular septal defect, non-confluent pulmonary arteries, and bilateral arterial duct is a rare and complex CHD. Physiologic ductal closure may lead to life-threatening hypoxia. We present a case of successful bilateral ductal stenting as a bridge to further lower-risk surgical repair.

Implantation of atrial flow regulator devices in patients with congenital heart disease and children with severe pulmonary hypertension or cardiomyopathy-an international multicenter case series.

Background: The Occlutech Atrial Flow Regulator (AFR) is a self-expandable double-disc nitinol device with a central fenestration. Its use has been approved in the adult population with heart failure and described for pulmonary hypertension (PH). Only case reports and small series have been published about its use in the paediatric population and for congenital heart disease (CHD).

The Transcatheter Closure of Patent Ductus Arteriosus in Extremely Low-Birth-Weight Infants: Technique and Results.

Persistent patent ductus arteriosus is a very common condition in preterm infants. Although there is no management agreed by consensus, despite numerous randomized controlled trials, hemodynamically significant patent ductus arteriosus increases morbidity and mortality in these vulnerable patients. Medical treatment is usually offered as first-line therapy, although it carries a limited success rate and potential severe adverse events.

Prophylactic Intravenous Acetaminophen in Extremely Premature Infants: Minimum Effective Dose Research by Bayesian Approach.

Background: Patent ductus arteriosus (PDA) in preterm infants is associated with increased morbidities and mortality. Prophylactic treatment with cyclooxygenase inhibitors, as indomethacin or ibuprofen, failed to demonstrate significant clinical benefits. Acetaminophen may represent an alternative treatment option.

E-Health: A Game Changer in Fetal and Neonatal Cardiology?

Technological advancements have greatly impacted the healthcare industry, including the integration of e-health in pediatric cardiology. The use of telemedicine, mobile health applications, and electronic health records have demonstrated a significant potential to improve patient outcomes, reduce healthcare costs, and enhance the quality of care. Telemedicine provides a useful tool for remote clinics, follow-up visits, and monitoring for infants with congenital heart disease, while mobile health applications enhance patient and parents' education, medication compliance, and in some instances, remote monitoring of vital signs.

Transcatheter Closure of Superior Sinus Venosus Defects.

Superior sinus venosus defect is a communication between the right and left atrium located above the upper margin of the oval fossa, immediately inferior to the junction of the superior vena cava and the right atrium. It is systematically associated with partial anomalous pulmonary venous drainage, especially of the right upper pulmonary vein. Surgical repair has been the gold standard approach to close that defect.

Late aortic obstruction due to ductal vasoconstriction on pulmonic end after transcatheter patent ductus arteriosus closure in an extremely low-birth-weight infant.

Device-induced aortic obstruction is a known rare complication following transcatheter closure of patent ductus arteriosus in extremely low-birth-weight infants. Various mechanisms have been proposed. We report the first description of late aortic obstruction due to ductal vasoconstriction on pulmonic end causing device to be gradually pushed out of aortic end in a 980-gram premature infant.
