Postoperative Outcomes of Fontan Operation in a Multicenter Italian Study. How Far Have We Gone? Early Outcomes After Fontan Operation.

Despite the clinical results of the Fontan operation have certainly improved, it still presents with an inherent surgical risk of death and early morbidities. This is a retrospective clinical study of children undergoing Fontan operation in 9 congenital cardiac centers in Italy between 1990 and 2023. Clinical and surgical data were collected via a dedicated RedCap database.

Cardiac Phenotype and Gene Mutations in RASopathies.

Cardiac involvement is a major feature of RASopathies, a group of phenotypically overlapping syndromes caused by germline mutations in genes encoding components of the RAS/MAPK (mitogen-activated protein kinase) signaling pathway. In particular, Noonan syndrome (NS) is associated with a wide spectrum of cardiac pathologies ranging from congenital heart disease (CHD), present in approximately 80% of patients, to hypertrophic cardiomyopathy (HCM), observed in approximately 20% of patients. Genotype-cardiac phenotype correlations are frequently described, and they are useful indicators in predicting the prognosis concerning cardiac disease over the lifetime.

[Italian Society of Pediatric Cardiology (SICP) position paper on the prevention, diagnosis, treatment and follow-up of cardiotoxicity in pediatric patients with cancer].

The survival of pediatric cancer patients has significantly increased thanks to the improvement of oncological treatments. Therefore, it is of utmost importance to manage short- and long-term cardiovascular complications. In pediatric cardio-oncology, there are no recognized guidelines as in adults.

Rapid transesophageal atrial pacing for balloon aortic valvuloplasty in neonates and infants: A new technique for balloon stabilization.

Balloon aortic valvuloplasty (BAV) is preferred by most centers over surgery for the treatment of congenital valve stenosis, due to its less invasive nature and faster recovery time. A variety of techniques have been employed to induce a transient cardiac standstill and reduce longitudinal balloon displacement during valve dilatation. Rapid right ventricular (RV) pacing is an effective method to stabilize the balloon during aortic valvuloplasty and it is regularly used in older children and adults.

Transcatheter Interventions for Neonates with Congenital Heart Disease: A Review.

Newborns with congenital heart disease often require interventions linked to high morbidity and mortality rates. In the last few decades, many transcatheter interventions have become the first-line treatments for some critical conditions in the neonatal period. A catheter-based approach provides several advantages in terms of procedural time, length of hospitalization, repeatability and neurodevelopmental issues (usually related to cardiopulmonary bypass).

Incidence and Prevalence of Multisystem Inflammatory Syndrome in Children (MIS-C) in Southern Italy.

Multisystem inflammatory syndrome in children (MIS-C) is a pediatric hyperinflammatory syndrome related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection whose epidemiology is not very well known at present. The objective of the study was to better understand the incidence of MIS-C in the Apulia region in southern Italy. Our primary goal was to estimate the incidence of newly identified cases of MIS-C in children aged 0-18 years, during a period of six months, encompassing the second pandemic wave.

[Heart involvement in multisystem inflammatory syndrome in children correlated with SARS-CoV-2 infection: a review by ANMCO/SICP].

Acute clinical manifestations of COVID-19 are generally less severe in childhood, however a proportion of them can develop a severe systemic hyperinflammatory syndrome after SARS-CoV-2 infection, known as the multisystem inflammatory syndrome (multisystem inflammatory syndrome in children, MIS-C). Cardiovascular manifestations in MIS-C are frequent (34-82%), including myocardial dysfunction, coronary artery dilation or aneurysms, arrhythmias, conduction abnormalities, pericarditis and valvulitis. The most affected cases can develop cardiogenic shock needing intensive care unit admission, inotropic support and sometimes even mechanical circulatory support.

Efficacy of sildenafil and high-dose anakinra in an MIS-C patient with pulmonary vasculitis: A case report.

Multisystem inflammatory syndrome in children (MIS-C) is a newly identified clinical entity still not very well known in terms of epidemiology, pathogenesis, and long-term outcome. Pulmonary involvement with acute respiratory failure is an unusual life-threatening complication of MIS-C, often a reason for admission to the pediatric intensive care unit (PICU) and the use of mechanical ventilation. We present a case of a 7-year-old male patient, previously healthy, hospitalized for MIS-C, treated with intravenous immunoglobulins (IVIG), high dose methylprednisolone, and anakinra.

A large basal left ventricular pseudoaneurysm following pediatric cardiac surgery.

Left ventricular pseudoaneurysm (LV-PSA) is a rare complication in children, usually developing after cardiac surgery, percutaneous procedures, infections, or trauma. Herein, we report a case of large basal submitral LV-PSA in a 36-day-old baby, detected 26 days after cardiac operation for hypoplastic arch, aortic coarctation, and small ventricular septal defect. No complications occurred in the first postoperative course, and early postoperative echocardiograms were normal.

[Proposal of a common model for informed consent for interventional procedures in congenital heart disease patients].

Background: A multidisciplinary study group involving physicians and jurists was established to review and approve an informed consent about the most frequent interventional procedures for congenital heart diseases.

Methods: The authors worked together with representatives of the Italian Society of Pediatric Cardiology and Congenital Heart Disease (SICP) Council and Jurist's expert in the field of health case-law. The final draft was shared with the major Italian centers involved in congenital interventional procedures and with AICCA, the Italian Patients Association of Congenital Heart Diseases - Adults and Children.

Local device infection successfully treated without pacemaker removal in a neonate: a case report.

Local device infection is a serious complication, especially in neonates. Complete device removal is the gold standard treatment for cardiac device infection; however, in selected cases alternative strategies could be adopted. We describe a case of a 14-day-old neonate, weighing 2.

Impact of hard lockdown on interventional cardiology procedures in congenital heart disease: a survey on behalf of the Italian Society of Congenital Heart Disease.

The Coronavirus disease 2019 (COVID-19) pandemic has thoroughly and deeply affected the provision of healthcare services worldwide. In order to limit the in-hospital infections and to redistribute the healthcare professionals, cardiac percutaneous intervention in Pediatric and Adult Congenital Heart Disease (ACHD) patients were limited to urgent or emergency ones. The aim of this article is to describe the impact of the COVID-19 pandemic on Pediatric and ACHD cath laboratory activity during the so-called 'hard lockdown' in Italy.

[Treatment of heart failure in adult congenital heart disease].

The progressive shifting in adult patients with congenital heart disease (ACHD) epidemiology with aging and superimposed acquired cardiac pathology on top of complex congenital heart defects is leading to an increase of hospitalizations for heart failure (HF), which nowadays represents one of the main causes of death in this patient population. Although there is a theoretical evidence to support the use of conventional drugs indicated for the general population with HF, randomized controlled trials do often exclude ACHD patients. Anatomical and physiological heterogeneity makes it difficult to define the role of cardiac resynchronization, and indications are less established.

Percutaneous treatment of a double-drainage scimitar-like syndrome.

Scimitar syndrome is a rare variant of anomalous right pulmonary vein connection to the inferior vena cava and it is associated with other cardiopulmonary anomalies. It generally requires surgery and sometimes it may go unrecognised into adulthood. We report a unique case of a scimitar syndrome variant in a young adult, who was successfully treated percutaneously, after the first misdiagnosis of arrhythmogenic ventricular cardiomyopathy.

Cardiovascular, Brain, and Lung Involvement in a Newborn With a Novel FLNA Mutation: A Case Report and Literature Review.

Background: Filamin A (FLNA) is an intracellular actin-binding protein, encoded by the FLNA gene, with a wide tissue expression. It is involved in several cellular functions, and extracellular matrix structuring. FLNA gene alterations lead to diseases with a wide phenotypic spectrum, such as brain periventricular nodular heterotopia (PVNH), cardiovascular abnormalities, skeletal dysplasia, and lung involvement.

Resilience and response of the congenital cardiac network in Italy during the COVID-19 pandemic.

: The worldwide response to the current COVID-19 pandemic has been focused on how to prevent the disease and to protect the high-risk patient from a potentially lethal infection. Several consensus and guidelines articles have been published dealing with the cardiac patient with systemic hypertension, heart transplant or heart failure. Very little is known about the patients, both in the pediatric as well as in the adult age, with congenital heart disease.

Mid-Aortic Syndrome: A Rare Cause of Renovascular Hypertension in Childhood Treated Percutaneously with an Unusual Vascular Access.

Introduction: Mid-Aortic Syndrome (MAS) is a rare vascular malformation characterized by segmental narrowing of the abdominal aorta and stenosis of its principal branches. Patients affected by MAS typically present malignant renovascular hypertension, with variable clinical symptoms like claudication, abdominal angina, and headache. Moreover, they can develop other complications, such as hypertensive encephalopathy, congestive heart failure and vascular brain accidents.

Isolated persistence of the fifth aortic arch in an infant presenting with congestive heart failure.

The persistence of the fifth aortic arch (PFAA) in postnatal life is an extremely rare and controversial cardiovascular malformation. PFAA is defined as an extra-pericardial vessel arising from the ascending aorta proximal to the origin of the brachiocephalic arteries, terminating either in the dorsal aorta or in the pulmonary arteries through the persistently patent arterial duct. An isolated PFAA with systemic-to-pulmonary connection best fits this definition, while the vast majority of cases reported as PFAA may have alternative embryological explanations.

Balloon angioplasty of aortic coarctation in critically ill newborns using axillary artery access.

Balloon angioplasty may be performed as the first treatment of aortic coarctation to stabilize newborns too sick for immediate surgery. The issue of vascular access is the key to the successful treatment of critical newborns. In our study, we argue that the lesser-known axillary access route is the safest and most effective route of vascular access for balloon angioplasty in infants with aortic coarctation.

[Physiological and paraphysiological echocardiographic findings in neonatal and pediatric age].

Echocardiographic quantification is crucial for the diagnosis and management of patients with acquired and congenital heart disease (CHD). In neonatal and pediatric age, the echocardiogram begins with subxiphoid, or subcostal, imaging instead of left parasternal views. This allows for the determination of visceral situs (site or location) at the beginning of an examination.

A situs solitus transposition of great arteries with obstructed sub-diaphragmatic totally anomalous pulmonary venous connection: a rare case treated with anatomical repair.

Transposition of the great arteries combined with totally anomalous pulmonary venous connection is extremely rare outside of heterotaxy syndrome. Most reported cases have been treated by a modified atrial switch operation. We report the successful treatment of a neonate with this rare association, repaired by arterial switch operation and connection of the pulmonary venous return to the left atrium.

Endomyocardial biopsy safety and clinical yield in pediatric myocarditis: An Italian perspective.

Objectives: The objective of this investigation is to evaluate the safety, the impact of endomyocardial biopsy (EMB) results in myocarditis management and the incidence of different etiologies of myocarditis in a pediatric population.

Background: Although EMB is an established diagnostic tool to evaluate suspected myocarditis, there is lack of clear diagnostic and management guidelines for myocarditis in pediatric patients, particularly in infants.

Methods: We performed a retrospective database review and subsequent outcomes analysis from five Italian pediatric cardiology centers to identify patients aged 0-18 years who underwent EMB for suspected myocarditis or inflammatory cardiomyopathy (ICMP) between 2009 and 2011.
