Transcatheter Interventions in Adults With Fontan Palliation.

The Fontan circuit is associated with chronically elevated systemic venous pressures and decreased cardiac output, often leading to circuit failure. Managing Fontan circuit failure is complex and requires multiple therapeutic options. Transcatheter interventions have emerged as a reliable approach.

Scimitar Syndrome in a Pediatric Cohort.

Background: Scimitar syndrome is a rare form of congenital heart disease (CHD) characterized by anomalous pulmonary venous drainage of the right lung to the inferior vena cava. We describe the presentation, diagnosis, therapeutic management and long-term follow-up of 10 pediatric patients with Scimitar Syndrome.

Methods: We performed a retrospective observational study of all pediatric patients from our institution with scimitar syndrome (March 1996-July 2023).

Myhre syndrome: expanding its paediatric phenotypic spectrum.

Myhre syndrome is a rare disease secondary to pathogenic variants in gene. It is a multisystem disease characterised by short stature, deafness, joint stiffness, craniofacial dysmorphism, and potential cardiac manifestations. Herein, we report two new paediatric cases of Myhre syndrome who, additionally, presented with mid-aortic syndrome.

Interrupted Aortic Arch Associated With Aortopulmonary Window: The Role of Multidetector Computed Tomography Angiography.

We report a case of a 2-day-old male with a diagnosis of interrupted aortic arch combined with aortopulmonary window suspected through echocardiography and confirmed by multidetector computer tomography (MDCT) angiography. Our case highlights how MDCT angiography was a key factor in planning surgical approach as it not only accurately defined aortic arch anatomy but also aortopulmonary window morphology.

Mid-aortic Syndrome in a Pediatric Cohort.

Mid-aortic syndrome (MAS) is an uncommon condition characterized by severe narrowing of the abdominal aorta, usually involving visceral and renal arteries. Most patients are asymptomatic and typically present with incidental hypertension which might evolve into end-organ damage if untreated. Our aim was to review 8 new pediatric MAS cases.

Massive Dilatation of the Ascending Aorta in a Patient With Generalized Arterial Calcification of Infancy.

We report a case of massive ascending aortic dilatation in a patient with generalized arterial calcification of infancy (GACI). He was found to carry compound heterozygous mutations in gene, previously associated with pseudoxanthoma elasticum, although recently linked to GACI. Our case confirms previous reports of a genotypic overlap between both entities.

Neonatal Rupture of the Tricuspid Valve and Maternal Lupus: Is There a Correlation?

Valve dysfunction is not widely recognized as a feature in newborns born to mothers with positive anti-Ro/SSA antibodies, and only scarce reports have suggested an association between rupture of the atrioventricular valve tensor apparatus and these maternal antibodies. We report the follow-up from fetal life to the time of postnatal surgery of a patient with severe tricuspid regurgitation due to a flail of the anterior tricuspid valve leaflet who was born to an anti-Ro/SSA antibodies positive mother.

Expanding percutaneous treatment of mitral valve diseases: Transcatheter closure of mitral valve leaflet perforation.

Mitral valve perforation is a rare cause of mitral regurgitation. We present a case of a 16-year-old patient with mitral valve regurgitation after redo-cardiac surgery for recurrent subaortic stenosis. Transthoracic echocardiography revealed a mitral regurgitation with an eccentric jet causing a significant regurgitation documented by the presence of a convergence flow over the hole.

Neonatal Non-compacted Cardiomyopathy: Predictors of Poor Outcome.

Non-compacted cardiomyopathy (NCM) is a heterogenous myocardial disorder. Although much has been published in recent years, little is known about NCM in the neonatal period. The objective of this study is to characterize the involvement of newborns affected with NCM and to identify risk factors associated with increased mortality.
