Objective: To evaluate the performance of Fetal Intelligent Navigation Echocardiography (FINE) applied to spatiotemporal image correlation (STIC) volume datasets of the normal fetal heart in generating standard fetal echocardiography views. Methods: In this prospective cohort study of patients with normal fetal hearts (19-30 gestational weeks), one or more STIC volume datasets were obtained of the apical four-chamber view. Each STIC volume successfully obtained was evaluated by STICLoop™ to determine its appropriateness before applying the FINE method. Visualization rates for standard fetal echocardiography views using diagnostic planes and/or Virtual Intelligent Sonographer Assistance (VIS-Assistance®) were calculated. Results: One or more STIC volumes (total n = 463) were obtained from 246 patients. A single STIC volume per patient was analyzed using the FINE method. In normal cases, FINE was able to generate nine fetal echocardiography views using: (1) diagnostic planes in 76-100% of the cases, (2) VIS-Assistance® in 96-100% of the cases, and (3) a combination of diagnostic planes and/or VIS-Assistance® in 96-100% of the cases. Conclusion: FINE applied to STIC volumes can successfully generate nine standard fetal echocardiography views in 96-100% of cases in the 2nd and 3rd trimesters. This suggests that the technology can be used as a method of screening for congenital heart disease.

Limited options do exist for mechanical circulatory support as a bridge to transplantation in the pediatric population. This is especially true when it comes to intracorporeal technologies. We describe our successful experience with the use of HeartWare ventricular assist devices (HeartWare, Inc., Framingham, MA, USA) in three patients <16 years of age, as a successful and feasible bridge to transplant in patients weighing greater than 20 kg.

Aims Multisystem inflammatory syndrome in children (MIS-C) with cardiovascular manifestations are frequent. However, there is lacking evidence regarding cardiological follow-up of this cohort of patients. The aim of our study was to describe the early and mid-term cardiac abnormalities assessed by standard and speckle-tracking echocardiography (STE), and cardiac MRI (CMR). Methods and results We enrolled 32 patients (21 male, 11 female), mean age 8.25 ± 4years, with diagnosis of MIS-C. During admission, all children underwent TTE, STE with analysis of left ventricle global longitudinal strain (GLS) and CMR. Patients underwent cardiological evaluation at 2 (T1) and 6 months (T2) after discharge. Cardiac MRI was repeated at 6 months after discharge. Mean left ventricular ejection fraction (LVEF) at baseline was 58.8 ± 10% with 10 patients (31%) below 55%. Speckle-tracking echocardiography showed reduced mean LV GLS (−17.4 ± 4%). On CMR, late gadolinium enhancement (LGE) with non-ischaemic pattern was evident in 8 of 23 patients (35%). Follow-up data showed rapid improvement of LVEF at T1 (62.5 ± 7.5 vs. 58.8 ± 10.6%, P-value 0.044) with only three patients (10%) below ≤ 55% at T1. Left ventricular (LV) GLS remained impaired at T1 (−17.2 ± 2.7 vs.−17.4 ± 4, P-value 0.71) and significantly improved at T2 (−19 ± 2.6% vs. −17.4 ± 4%, P-value 0.009). LV GLS was impaired (&gt;−18%) in 53% of patients at baseline and T1, whereas only 13% showed persistent LV GLS reduction at T2. Follow-up CMR showed LGE persistence in 33.4% of cases. Conclusion Early cardiac involvement significantly improves during follow-up of MIS-C patients. However, subclinical myocardial dysfunction seems to be still detectable after 6 months of follow-up in a not negligible proportion of them.

Primary cardiac tumours in infants and children are extremely rare, with an estimated incidence of 0.2% according to echocardiographic studies. Owing to their rarity, there is very little literature available, and most knowledge is based on collections of case reports. Therefore, we reviewed retrospectively our 27 years of clinical experience on the overall management of cardiac tumours among children in order to improve not only our knowledge but also to provide others with information about the incidence, clinical presentation, management, and long-term outcome of this rare disease. Between April, 1982 and April, 2009, 52 children were diagnosed with cardiac tumours at our Institution. Medical records and follow-up echocardiographic evaluations were studied. The diagnosis was prenatal in 35% of the patients. The most frequent tumour types were rhabdomyomas (61.5%), fibromas (15.4%), and myxomas (5.8%). There were no cases of primary malignant tumours. All diagnoses were achieved using two-dimensional echocardiography, and for 12 patients a pathological analysis was carried out. A total of 41 patients (79%) were managed medically, whereas 11 (21%) patients underwent surgical treatment. At a mean follow-up of 7.2 ± 5.4 years, two patients died of complications related to cardiac transplantation; all the remaining patients are in excellent clinical condition. In conclusion, cardiac tumours in paediatric practice are usually clinically and histologically benign. Only a few cases need surgery. Up to one-third of the cardiac masses are detectable prenatally. Rhabdomyoma is the most common histotype, followed by fibroma and myxoma. The long-term prognosis is generally good.
