Transcatheter Closure of a Patent Foramen Ovale With a Small Adjacent Atrial Septal Defect and a Double Interatrial Septum Post Cryptogenic Stroke.

The phenomenon of double interatrial septum (DIAS) represents a particularly rare subtype of atrial septal malformation, characterized by the presence of dual membranes separating the atria, resulting in a distinctive interatrial space. This unique anatomical structure has been linked to a paradoxical right-to-left shunt, potentially contributing to embolic ischemic strokes. Within this context, we report a rare case of a 34-year-old female who presented with a transient ischemic attack (TIA) and was diagnosed with patent foramen ovale (PFO) and a small adjacent atrial septal defect (ASD), along with the presence of a DIAS.

Medium-Term Outcomes of Stent Therapy for Aortic Coarctation in Children Under 30 kg with New Generation Low-Profile Stents: A Follow-Up Study of a Single Centre Experience.

We previously reported short-term outcomes for stenting of aortic coarctation (CoA) (native or re-coarctation) with newer generation low-profile stents (Valeo, Formula, and Begraft stents) in children under 30 kg. We present here the medium-term outcomes of this procedure. Retrospective review of patients weighing under 30 kg who had percutaneous stent treatments for coarctation between 2012 and 2021 was performed.

Outcome monitoring and risk stratification after cardiac procedure in neonates, infants, children and young adults born with congenital heart disease: protocol for a multicentre prospective cohort study (Children OMACp).

Introduction: Congenital heart disease (CHD) represents the most common birth defect, affecting from 0.4% to 1.2% of children born in developed countries.

Transcatheter pulmonary valve implant in a patient with a previous pulmonary valve-in-valve.

Unlabelled: Increasing numbers of patients with congenital heart disease now survive well into adulthood. Often, these patients already had surgery to correct their congenital lesions from early life. Patients with tetralogy of Fallot commonly require several pulmonary valve replacements in their lifetime.

Validating a risk assessment tool in United Kingdom and Irish paediatric cardiac catheterisation practice.

Background: No established risk prediction tool exists in United Kingdom and Irish Paediatric Cardiology practice for patients undergoing cardiac catheterisation. The Catheterisation RISk score for Paediatrics is used primarily in North American practice to assess risk prior to cardiac catheterisation. Validating the utility and transferability of such a tool in practice provides the opportunity to employ an already established risk assessment tool in everyday practice.

Allogeneic Mesenchymal Stromal Cell Injection to Alleviate Ischemic Heart Failure Following Arterial Switch Operation.

Cell therapy is a promising tool to prevent and treat heart failure in congenital heart disease. We report the first case of intramyocardial injection of allogeneic mesenchymal stromal cells as rescue therapy in a neonate with ischemic heart failure following arterial switch procedure for isolated transposition of the great arteries. ().

Age over 35 years is associated with increased mortality after pulmonary valve replacement in repaired tetralogy of Fallot: results from the UK National Congenital Heart Disease Audit database.

Objectives: Many adults with repaired tetralogy of Fallot will require a pulmonary valve replacement (PVR), but there is no consensus on the best timing. In this study, we aim to evaluate the impact of age at PVR on outcomes.

Methods: This is a national multicentre retrospective study including all patients >15 years of age with repaired tetralogy of Fallot who underwent their first PVR between 2000 and 2013.

Arterial switch procedure and hybrid muscular ventricular septal defect closure in a patient with d-transposition of the great arteries and multiple ventricular septal defects: a case report and literature review.

Hybrid cardiac surgery involves simultaneous catheter based and surgical treatment of heart diseases. We report a complete repair of dextro-transposition of the great arteries and perimembranous and muscular ventricular septal defects in a 5-month-old girl. This included an arterial switch operation followed by an off-bypass, echocardiographically guided per-ventricular muscular ventricular septal defect closure.

Surgical versus balloon valvotomy in neonates and infants: results from the UK National Audit.

Objective: There are conflicting data on choosing balloon aortic valvoplasty (BAV) or surgical aortic valvotomy (SAV) in neonates and infants requiring intervention for aortic valve stenosis. We aim to report the outcome of both techniques based on results from the UK national registry.

Methods: This is a retrospective study, including all patients under 1 year undergoing BAV/SAV between 2000 and 2012.

Duct Stenting Versus Modified Blalock-Taussig Shunt in Neonates With Duct-Dependent Pulmonary Blood Flow: Associations With Clinical Outcomes in a Multicenter National Study.

Background: Infants born with cardiac abnormalities causing dependence on the arterial duct for pulmonary blood flow are often palliated with a shunt usually between the subclavian artery and either pulmonary artery. A so-called modified Blalock-Taussig shunt allows progress through early life to an age and weight at which repair or further more stable palliation can be safely achieved. Modified Blalock-Taussig shunts continue to present concern for postprocedural instability and early mortality such that other alternatives continue to be explored.

Outcome after transcatheter occlusion of patent ductus arteriosus in infants less than 6 kg: A national study from United Kingdom and Ireland.

Objectives: This study aimed to report our national experience with transcatheter patent ductus arteriosus (PDA) occlusion in infants weighing <6 kg.

Background: The technique of transcatheter PDA closure has evolved in the past two decades and is increasingly used in smaller patients but data on safety and efficacy are limited.

Methods: Patients weighing < 6 kg in whom transcatheter PDA occlusion was attempted in 13 tertiary paediatric cardiology units in the United Kingdom and Ireland were retrospectively analyzed to review the outcome and complications.

Stent Therapy for Aortic Coarctation in Children <30 kg: Use of the Low Profile Valeo Stent.

To report our experience of coarctation stent therapy in small children weighing less than 30 kg, with the low profile dilatable Valeo stent and review the literature on coarctation stent therapy in this patient population. Coarctation stent implantation was undertaken in 14 consecutive children using the Bard Valeo Stent. Demographic, angiographic, echocardiographic and clinical data were reviewed retrospectively.

Severe Aortic Stenosis and Severe Coarctation of the Aorta: A Hybrid Approach to Treatment.

Unlabelled: Hybrid surgery is becoming more popular in the treatment of children with congenital heart disease, particularly small infants and neonates. We report a case of a patient with aortic stenosis (AS) and coarctation of the aorta (CoA).

Case: a 1-month-old baby presented with severe AS and CoA.

Techniques for transcatheter retrieval of the occlutech ASD device United Kingdom-European multicenter report.

To gather current experience in Occlutech ASD device retrieval, to determine whether snaring is an effective technique and to highlight alternative retrieval techniques; METHODS AND RESULTS: United Kingdom and European Occlutech ASD device implanters reported their experience in dealing with device embolization and retrieval. Six operators reported 12 retrieval cases. Retrieval was successful in 92% (11/12), although in most cases it was not straightforward and required multiple attempts using different techniques and equipment.

The new occlutech duct occluder: immediate results, procedural challenges, and short-term follow-up.

Objective: The aim of this study was to assess the immediate and short-term results of transcatheter closure of patent ductus arteriosus (PDA) using the Occlutech duct occluder (ODO).

Background: The ODO is a new self-expanding nitinol device. Its body is wider at the pulmonary artery end than the aortic end.

Implantation and preliminary follow-up of the Bard Valeo stent in pulmonary artery stenosis.

Objectives: To evaluate the performance of the Bard Valeo stent in pulmonary artery stenoses.

Background: The premounted Valeo stent requires only 6-7 French access and can be post-dilated to 20 mm on bench testing. Although it appears ideal for implantation in pulmonary artery stenoses in children, it has been unclear whether it has sufficient radial strength to prevent vessel recoil and stent collapse.

Percutaneous coronary intervention in a 3-year-old with hypoplastic left heart syndrome.

Mortality outcomes associated with surgical palliation for hypoplastic left heart syndrome (HLHS) have continued to improve with time. Despite these advances, interstage mortality continues to be difficult to predict and prevent. This case report details a 3-year-old boy with HLHS palliated with a Glenn shunt who presented with acute myocardial infarction due to near total occlusion of the distal right coronary artery.

Rare association of a patient with Alagille syndrome and mitral valve regurgitation.

A 9-year-old patient with known Alagille syndrome presented to our institution with progressive mitral valve regurgitation due to prolapse of the posterior valve leaflet. She underwent successful mitral valve replacement with a mechanical prosthesis 4 years after the initial diagnosis. To the best of our knowledge, an association between mitral valve regurgitation and Alagille syndrome has not been previously described.
