Objectives: Coronary artery fistulas (CAFs) are rare congenital anomalies with an occurrence rate of 0.002–0.3%. The right coronary artery (RCA) is reportedly the most common site of origin of CAFs, but fistulas draining to the left atrium (LA) are rare. We presented a three-year-old boy with a symptomatic congenital RCA-to-LA fistula, which was successfully percutaneously occluded with an Amplatzer vascular plug 4 (AVP4). Case report: The diagnosis was made by echocardiography when he was two months old. During the follow-up period of 2 years, a progressive dilatation of the RCA and enlargement of the left ventricle was detected, so treatment for congestive heart failure was initiated. At the age of three, the patient presented with a history of occasional mild central chest pain and discomfort and mild dyspnea on exertion. On a 24 h ECG Holter monitor, the depression of ST segments was registered. CT angiography highlighted a large type B RCA fistula to the LA, which extended along the atrioventricular sulcus. The proximal RCA diameter was 7 mm. The fistula was tortuous, with segmental narrowing and three curves. Cardiac catheterization was performed across the right femoral artery on the three-year-old boy (body weight: 13 kg). Across the 4F Judkins right guiding catheter, an AVP4 of 5 mm was placed in the distal part of the CAF connected with the delivery cable. After 15 min, ECG changes were not registered, so the device was released. Immediate post-deployment angiography demonstrated complete CAF occlusion, with satisfying flow in the distal coronary artery. The patient was discharged after four days. In the short-term follow-up period, the boy was symptom-free. Conclusions: In our experience, given the existence of the left-to-left shunt and the more pronounced exercise-induced coronary steal phenomenon that occurs in medium-sized and large CAFs, occlusion is necessary to prevent the further progression of clinical signs and symptoms.

Endomyocardial biopsy (EMB) is a well-known diagnostic tool for the investigation and treatment of myocardial diseases and remains the gold standard for the diagnosis of myocarditis. Due to its invasiveness, with a complication rate ranging from 1 to 15%, its role in the diagnostic work-up of pediatric heart failure is not well established. The aim of this review is to define the role of EMB as diagnostic technique in the work up of children presenting with severe left ventricular dysfunction with the support of our center experience.

Background Trisomy 18 was once considered a fatal diagnosis due to the presence of cardiac and extracardiac lesions. However, with the increasing use of therapeutic management, 3% to 25% of infants with trisomy 18 may survive beyond their first year, depending on the interventions provided. Currently, there are no clear and widely accepted criteria to guide medical decisions for children with trisomy 18. This means that patients could often be at risk of either over-treatment or therapeutic abandonment. We aimed to explore the effectiveness of intensive and non-intensive treatments in enhancing the clinical burden of disease and survival of children with trisomy 18 syndrome Methods a retrospective monocentric study in Bambino Gesù Children’s Hospital, IRCCS Rome, Italy. We enrolled all patients discharged from our hospital with genetic diagnosis of trisomy 18 between 2018 and 2023. Clinical data from birth were collected and categorized into two groups: those who received intensive treatment and those who underwent a palliative approach. Intensive treatment was defined as corrective heart surgery, use of invasive respiratory support, or at least one hospitalization in an intensive care unit. Survival probabilities at different age intervals were calculated, and the clinical burden of disease was assessed, taking into account device dependence, number of emergency department visits per year, and the daily intake of medications at home Results 32 patients were enrolled. Children with a low device dependence had significantly higher survival(p= 0,01). Neither palliative nor corrective heart surgery affected survival for patients with major cardiac defects. Conversely in children with minor heart defects surgery significantly increased survival probability(p= 0.01), particularly the corrective approach(p= 0.01). High number of emergency department visits(p=0.03) and high number of drugs taken daily(p=0.02) significantly reduced survival. No significant differences emerged between the two groups in terms of burden of disease. Conclusions proportional to the initial clinical conditions all treatment options, which may include both comfort care and heart surgery, should be re-evaluated to determine the approach that prioritizes the best interest of each child with trisomy 18.

The alarming onset of some cases of myocarditis and pericarditis following the administration of Pfizer–BioNTech and Moderna COVID-19 mRNA-based vaccines in adolescent males has recently been highlighted. All occurred after the second dose of the vaccine. Fortunately, none of patients were critically ill and each was discharged home. Owing to the possible link between these cases and vaccine administration, the US and European health regulators decided to continue to investigate the potential causal relationship between COVID-19 mRNA vaccines and myocarditis. In any case, none of the patients fulfilled the criteria for multi-system inflammatory syndrome or Kawasaki-like disease and there was no evidence of acute SARS-CoV-2 infection.

[...]in many studies it was not reported if either the right or left arm was used to check BP. [...]publication bias was present as shown by funnel plot analysis and Egger’s test. [...]arterial hypertension may be found in up to 57% of subjects during long-term follow-up even in absence of restenosis and prosthetic material.4 Furthermore, several studies showed no differences in rate of hypertension between surgery and stent.5 6 Interesting studies in porcine model7 and computational fluid dynamic simulations8 have also shown that stent implantation does not impact on compliance, ventricular workload and blood flow.

Atrial septal defect (ASD) associated with left ventricular (LV) diastolic dysfunction (DD) is rare in children. DD is common in elderly patients undergoing ASD closure. Restrictive physiology among children undergoing percutaneous ASD closure is something unexpected that has not been described before in the literature. Hence, we report on a case of a child referred to our center for ASD closure in which an LV DD has been unmasked with a balloon occlusion test and has been managed with pharmacological preconditioning and subsequent ASD closure with good outcome. Albeit rare, LV DD can occur on children undergoing ASD closure.

Percutaneous closure of atrial septal defect (ASD) is a valid alternative to surgical approach. Current device has significantly improved the success rate also in complex cases. The aim of this study is to assess the impact of age, defect size, and morphologic features on successfully percutaneous ASD closure. Between January 2000 and September 2004, 1,013 consecutive patients underwent closure of an isolated type II ASD at our institution. The following outcomes have been evaluated: (1) role of percutaneous ASD closure as alternative to surgical repair, in current daily practice; (2) impact of age on the selected closure approach; (3) analysis of morphologic variety of ASD and its effect on the closure technique; (4) possible role of specific device selection according to ASD morphology to improve procedural success. During the study period, up to 80% of secundum ASDs were suitable for percutaneous closure with the currently available devices. Need for surgical ASD closure was more common in pediatric patients, likely reflecting the more frequent diagnosis of larger and complex defects at a young age. Accurate ADS morphology assessment and appropriate device selection are key elements to obtain procedural success. In particular, among all the ASD characteristics, the rim absence is the main limiting factor to a successful percutaneous ASD closure. A trend of reduction in peri-procedural adverse events was observed during the study period, with complications needing immediate cardiac surgery occurred only in 1% of cases. Percutaneous ASD closure is feasible and associated with low complication rate. A thorough analysis of morphologic aspects is mandatory in order to select the appropriate device and the optimal approach. Surgical closure remains the treatment of choice in selected patients.

Ductal patency of preterm infants is potentially associated with long term morbidities related to either pulmonary overflow or systemic steal. When an interventional closure is needed, it can be achieved with either surgical ligation or a catheter-based approach. Transcatheter PDA closure is among the safest of interventional cardiac procedures and it is the first choice for ductal closure in adults, children, and infants weighing more than 6 kg. In preterm and very low birth weight infants, it is increasingly becoming a valid and safe alternative to ligation, especially for the high success rate and the minor invasiveness and side effects. Nevertheless, being it performed at increasingly lower weights and gestational ages, hemodynamic complications are possible events to be foreseen. Procedural steps, timing, results, possible complications and available monitoring systems, as well as future outlooks are here discussed.

Key Clinical Message The case highlights the good survival after radical surgery and chemotherapy of a cardiac sarcoma, and the need for close follow‐up due to possible early postsurgical complications.
