Double-outlet left ventricle (DOLV) is an abnormal ventriculo-arterial connection characterized by the origin of both great arteries from the morphological left ventricle. The aim of our paper is to describe the morphological and imaging features of DOLV and to assess the prevalence of the associated malformations and their surgical outcomes. METHODS From 2011 to 2022, we retrospectively reviewed the electronic case records of patients diagnosed with DOLV at the Bambino Gesu Children's Hospital. A systematic search was developed in MEDLINE, Web of Science, and EMBASE databases to identify reports assessing the morphology and outcomes of DOLV between 1975 and 2023. RESULTS: Over a median follow-up of 9.9 years (IQR 7.8-11.7 y), four cases of DOLV were identified at our institution. Two patients were diagnosed with (S,D,D) DOLV subaortic VSD and pulmonary stenosis (PS): one patient had (S,D,D) DOLV with doubly committed VSD and hypoplastic right ventricle, and another patient had (S,D,L) DOLV with subaortic VSD and PS (malposition type). Pulmonary stenosis was the most commonly associated lesion (75%). LITERATURE REVIEW: After systematic evaluation, a total of 12 reports fulfilled the eligibility criteria and were included in our analysis. PS or right ventricular outflow tract obstruction was the most commonly associated lesion (69%, 95% CI 62-76%). The most common locations of VSD were subaortic (pooled prevalence: 75%, 95% CI 68-81), subpulmonary (15%, 95% CI 10-21), and doubly committed (7%, 95% CI 4-12). The position of the great arteries showed that d-transposition of the aorta was present in 128 cases (59% 95% CI 42-74), and l-transposition was present in 77 cases (35%, 95% CI 29-43).

Introduction: Type 2 diabetes mellitus (T2DM) is a non-communicable disease representing one of the most serious public health challenges of the twenty-first century. Its incidence continues to rise in both developed and developing countries, causing the death of 1.5 million people every year. The use of technology (e.g. smartphone application-App) in the health field has progressively increased as it has been proved to be effective in helping individuals manage their long-term diseases. Therefore, it has the potential to reduce the use of health service and its related costs. The objective of this study is to evaluate the impact of using a digital platform called "TreC Diabete" embedded into a novel organisational asset targeting poorly controlled T2DM individuals in the Autonomous Province of Trento (PAT), Italy., Methods: This trial was designed as a multi-centre, open-label, randomised, superiority study with two parallel groups and a 1:1 allocation ratio. Individuals regularly attending outpatient diabetes clinics, providing informed consent, are randomised to be prescribed TreC Diabete platform as part of their personalised care plan. Healthcare staff members will remotely assess the data shared by the participants through the App by using a dedicated online medical dashboard. The primary end-point is the evaluation of the Hb1Ac level at 12-month post-randomisation. Data will be analysed on an intention-to-treat (ITT) basis., Discussion: This trial is the first conducted in the PAT area for the use of an App specifically designed for individuals with poorly controlled T2DM. If the effects of introducing this specific App within a new organisational asset are positive, the digital platform will represent a possible way for people diagnosed with T2DM to better manage their health in the future. Results will be disseminated through conferences and peer-reviewed journals once the study is completed., Trial Registration: ClinicalTrials.gov NCT05629221.

The onset of cancer disease is a traumatic experience for both patients and their families that suddenly change the patient's life and is accompanied by important physical, emotional, and psycho-social problems. The complexity of this scenario has been exacerbated by the COVID-19 pandemic which dramatically affected the continuity of the provision of optimal care to chronic patients. Telemedicine can support the management of oncology care paths by furnishing a suite of effective and efficient tools to monitor the therapies of cancer patients. In particular, this is a suitable setting for therapies that are administered at home. In this paper, we present an AI-based system, called Arianna, designed and implemented to support and monitor patients treated by the professionals belonging to the Breast Cancer Unit Network (BCU-Net) along the entire clinical path of breast cancer treatment. We describe in this work the three modules composing the Arianna system (the tools for patients and clinicians, and the symbolic AI-based module). The system has been validated in a qualitative way and we demonstrated how the Arianna solution reached a high level of acceptability by all types of end-users by making it suitable for a concrete integration into the daily practice of the BCU-Net., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Background: The impact of genetic syndromes on cardiac magnetic resonance imaging (cMRI) parameters, particularly on right and/or left ventricular dysfunction, associated with clinical parameters following the repair of Tetralogy of Fallot (rToF) is not well known. Therefore, this study aimed to assess the differences in clinical, surgical, and cMRI data in syndromic and non-syndromic rToF patients., Methods: All syndromic rToF patients undergoing a cMRI without general anesthesia between 2010 and 2020 who were able to match with non-syndromic ones for birth date, sex, type of surgery, timing of cMRI, and BSA were selected. Demographic, clinical, surgical, MRI, ECG, and Holter ECG data were collected., Results: A total of one hundred and eight rToF patients equally subdivided into syndromic and non-syndromic, aged 18.7 ± 7.3 years, were studied. Del22q11.2 and Down syndrome (DS) were the most frequent syndromes (42.6% and 31.5%, respectively). Regarding the cMRI parameters considered, left ventricular (LV) dysfunction (LVEF < 50%) was more frequently found in syndromic patients ( p = 0.040). In addition, they were older at repair ( p = 0.002) but underwent earlier pulmonary valve replacement (PVR) (15.9 ± 5.6 vs. 19.5 ± 6.0 years, p = 0.049). On multivariate Cox regression analysis, adjusted for age at first repair, LV dysfunction remained significantly more associated with DS than del22q11.2 and non-syndromic patients (HR of 5.245; 95% CI 1.709-16.100, p = 0.004). There were only four episodes of non-sustained ventricular tachycardia in our cohort., Conclusions: Among the cMRI parameters commonly taken into consideration in rToF patients, LV dysfunction seemed to be the only one affected by the presence of a genetic syndrome. The percentage of patients performing PVR appears to be similar in both populations, although syndromic patients were older at repair and younger at PVR. Finally, the number of arrhythmic events in rToF patients seems to be low and unaffected by chromosomal abnormalities.

Background: The COVID-19 pandemic had a significant impact on the population's ability to be physically active. Purpose: Evaluate the effect of the COVID-19 mitigation measures on exercise tolerance in patients with congenital heart disease (CHD). Materials and methods: All subjects (880, 6-18 years old) who performed a stress test at our hospital from October 2020 to February 2021 and had a similar test one year earlier were enrolled. A questionnaire on the degree of physical activity carried out in 2020 concerning the period prior to the pandemic was compiled. Exercise tolerance and the main anthropometric parameters between the first and second tests were compared. Results: 110 subjects (11.9 ± 4.1 years) were included in the study. The percentage of patients engaged in regular physical activity (RPA) decreased significantly during the pandemic ( p < 0.001), and BMI increased significantly ( p < 0.001), except among the subjects who began RPA during the lockdown, whereas test duration did not decrease significantly overall but increased in this last subgroup ( p < 0.05) Conclusions: The COVID-19 lockdown led to a less active lifestyle with a significant increase in BMI in our group of CHD. These data could have negative effects on the risk profile of this population. RPA practiced at home seems to be effective in counteracting such effects.

Aim of these revised recommendations for the general management of Kawasaki disease is to encourage its prompter recognition and warrant the most appropriate therapy, based on ascertained scientific data, raising awareness of the complications related to misdiagnosis or delayed treatment. A set of 20 synthetic operative statements is herein provided, including the definition of Kawasaki disease, its protean presentations, clinical course and seminal treatment modalities of all disease phases. The application of these recommendations should improve prognosis of Kawasaki disease and prevent the progression to permanent vascular abnormalities, thereby diminishing morbidity and mortality.

Anomalous origin of the pulmonary arteries from the ascending aorta is a rare, but severe clinical entity necessitating a scrupulous evaluation. Either the right or the left pulmonary arteries can arise directly from the ascending aorta while the other pulmonary artery retains its origin from the right ventricular outflow tract. Such a finding can be isolated or can coexist with several congenital heart lesions. Direct intrapericardial aortic origin, however, must be distinguished with origin through a persistently patent arterial duct. In the current era, clinical manifestations usually become evident in the newborn rather than during infancy, as used to be the case. They include respiratory distress or congestive heart failure due to increased pulmonary flow and poor feeding. The rate of survival has now increased due to early diagnosis and prompt surgical repair, should now be expected to be at least 95%. We have treated four neonates with this lesion over the past 7 years, all of whom survived surgical repair. Right ventricular systolic pressure was significantly decreased at follow-up. Our choice of treatment was to translocate the anomalous pulmonary artery in end-to-side fashion to the pulmonary trunk. Our aim in this report is to update an Italian experience in the diagnosis and treatment of anomalous direct origin of one pulmonary artery from the aorta, adding considerations on the lessons learned from our most recent review of the salient literature., Competing Interests: There are no conflicts of interest.

Transcatheter creation or enlargement of an atrial septal defect has been used to promote adequate blood flow and mixing in some forms of congenital heart defects or as a relief valve in right or left atrial hypertension, resulting in better cardiac output and/or systemic saturation. We report a case of a 4-year-old male affected by complex congenital heart disease who was admitted for management of severe cyanosis following a staged pericardial fenestrated Fontan procedure. Transoesophageal echocardiogram showed a wide fenestration of 9 mm in size with a severely dilated pericardial Fontan system. To avoid a new surgical procedure and as part of a compassionate use programme, we decided to implant an atrial flow regulator device (4 mm in diameter) with percutaneous approach with the goal of reducing the right-to-left shunt and increasing the pulmonary flow. Preprocedural oxygen saturation was 75%, whereas after 2 months of follow-up, we observed a progressive increase of up to 95% with significant reduction in the pericardial Fontan system dimensions at echocardiography.

The primary purpose of these practical guidelines related to Kawasaki disease (KD) is to contribute to prompt diagnosis and appropriate treatment on the basis of different specialists' contributions in the field. A set of 40 recommendations is provided, divided in two parts: the first describes the definition of KD, its epidemiology, etiopathogenetic hints, presentation, clinical course and general management, including treatment of the acute phase, through specific 23 recommendations.Their application is aimed at improving the rate of treatment with intravenous immunoglobulin and the overall potential development of coronary artery abnormalities in KD. Guidelines, however, should not be considered a norm that limits treatment options of pediatricians and practitioners, as treatment modalities other than those recommended may be required as a result of peculiar medical circumstances, patient's condition, and disease severity or complications.

This second part of practical Guidelines related to Kawasaki disease (KD) has the goal of contributing to prompt diagnosis and most appropriate treatment of KD resistant forms and cardiovascular complications, including non-pharmacologic treatments, follow-up, lifestyle and prevention of cardiovascular risks in the long-term through a set of 17 recommendations.Guidelines, however, should not be considered a norm that limits the treatment options of pediatricians and practitioners, as treatment modalities other than those recommended may be required as a result of peculiar medical circumstances, patient's condition, and disease severity or individual complications.

Purpose: An optimal active-can lead configuration during implantable cardioverter defibrillator (ICD) placement is important to obtain an adequate defibrillation safety margin. The purpose of this multicenter study was to evaluate the rate of the first shock success at defibrillation testing according to the type of lead implant (single vs. dual coil) and shock polarity (cathodal and anodal) in a large series of consecutive patients who received transvenous ICDs., Methods: This was a multicenter study enrolling 469 consecutive patients. Single- versus dual-coil leads and cathodal versus anodal polarity were evaluated at defibrillation testing. In all cases, the value of the energy for the first shock was set to 20 J less than the maximum energy deliverable from the device., Results: A total of 469 patients underwent defibrillation testing: 158 (34 %) had dual-coil and 311 (66 %) had single-coil lead systems configuration, 254 (54 %) received anodal shock and 215 (46 %) received cathodal shock. In 35 (7.4 %) patients, the shock was unsuccessful. No significant differences in the outcome of defibrillation testing using single- versus dual-coil lead were observed but the multivariate analysis showed an increased risk of shock failure using cathodal shock polarity (OR 2.37, 95 % CI 1.12-5.03)., Conclusions: Both single- and dual-coil transvenous ICD lead systems were associated with high rates of successful ICD implantation, and we found no significant differences in ventricular arrhythmias interruption between the two ICD lead systems configuration. Instead, anodal defibrillation was more likely to be successful than cathodal defibrillation.

Background: Kawasaki disease (KD) is a systemic vasculitis that mainly affects coronary arteries in children, and requires regular follow-up from the time of diagnosis., Objective: To evaluate the feasibility of 64-slice CT angiography (CTA) for follow-up of patients with KD using previously performed invasive catheter coronary angiography (CCA) as reference standard., Materials and Methods: The study group comprised 12 patients (age 17.6 ± 2.9 years, mean ± SD) with a diagnosis of KD and a previously performed CCA (interval, 32.6 ± 13.5 months) who underwent 64-slice cardiac CTA. The quality of the images for establishing the presence of coronary abnormalities was determined by two observers. The CTA findings were compared with those from the prior CCA., Results: Adequate image quality was obtained in all patients. Mean effective dose for CTA was 6.56 ± 0.95 mSv. CTA allowed accurate identification, characterization and measurement of all coronary aneurysms (n = 32), stenoses (n = 3) and occlusions (n = 9) previously demonstrated by CCA. One patient with disease progression went on to have percutaneous coronary intervention., Conclusion: Coronary lesions were reliably evaluated by 64-slice CTA in the follow-up of compliant patients with KD, reducing the need for repeated diagnostic invasive CCA. Hence, in an adequately selected patient population, the role of CCA could be limited almost only to therapeutic procedures.

We sought to determine if changes in myocardial physical properties, detected by ultrasound tissue characterization (UTC), are present in asymptomatic children years after an acute episode of Kawasaki disease (KD) and if such changes are related to coronary artery aneurysms (CAs). Myocardial UTC analysis was performed 4.8 + or - 3.4 years after acute KD in 22 patients, mean age 6.6 + or - 3.4 years, with or without CA, who had a normal ECG and normal left ventricular (LV) systolic and diastolic function by echocardiography. Twenty-two age-matched subjects were studied as controls. Cyclic variation of integrated backscatter (cvIBS) and calibrated integrated backscatter (cIBS) were assessed in 16 LV myocardial segments in each patient and control. We found large differences in the UTC data between patients and controls: cvIBS, 7.8 + or - 0.8 vs 8.9 + or - 0.6 dB; cIBS, 28.6 + or - 3.2 vs 25.2 + or - 1.0 dB (P\10-3 for both). The average values of cIBS and cvIBS did not differ significantly between KD patients with and patients without CA or stenosis. In conclusion, UTC analysis demonstrated significant differences in myocardial tissue properties between KD patients and controls, despite similar measures of LV function, independent of coronary artery abnormalities. UTC analysis might improve risk stratification for KD patients.

A right aortic arch with a left descending aorta and an aberrant left innominate artery is a rare but recognized vascular anomaly that can result in compression of the trachea and the esophagus. This vascular anomaly has been diagnosed using cardiac catheterization and angiography. Recently, computed tomography and magnetic resonance imaging have been used for noninvasive diagnosis. The aim of this report is to highlight the possibility of echocardiographic diagnosis., (Copyright 2010 American Society of Echocardiography. Published by Mosby, Inc. All rights reserved.)

GATA4 mutations are found in patients with different isolated congenital heart defects (CHDs), mostly cardiac septal defects and tetralogy of Fallot. In addition, GATA4 is supposed to be the responsible gene for the CHDs in the chromosomal 8p23 deletion syndrome, which is recognized as a malformation syndrome with clinical symptoms of facial anomalies, microcephaly, mental retardation, and congenital heart defects. Thus far, no study has been carried out to investigate the role of GATA4 copy number variations (CNVs) in non-syndromic CHDs. To explore the possible occurrence of GATA4 gene CNVs in isolated CHDs, we analyzed by multiplex ligation-dependent probe amplification (MLPA) a cohort of 161 non-syndromic patients with cardiac anomalies previously associated with GATA4 gene mutations. The patients were mutation-negative for GATA4, NKX2.5, and FOG2 genes after screening with denaturing high performance liquid chromatography. MLPA analysis revealed that normalized MLPA signals were all found within the normal range values for all exons in all patients, excluding a major contribution of GATA4 gene CNVs in CHD pathogenesis.

Other authors have demonstrated the ability of three-dimensional (3D) echocardiography to produce "en face" views of anomalies such as atrioventricular valve disease and atrial and ventricular septal defects. Few data exist about the usefulness of 3D images for more complex congenital heart defects and the surgical impact of this relatively new technology. This study, covering a period of 8 months and including 43 young patients affected by complex congenital heart defects, demonstrated that the routine use of 3D echocardiography is feasible and valuable for some types of cardiac defects. In fact, 3D images have provided more detailed anatomic definition of interrelations between structures in about one-third (15/43) of our cases, yielding new insight into the anatomy analogous to what can be derived from examining a heart specimen. Our surgeons found the 3D images particularly helpful for providing a realistic and almost specimen-like preview of the surgical anatomy that facilitates planning of the surgical program.

The oculo-auriculo-vertebral spectrum (OAVS) is a non-random association of microtia, hemifacial microsomia with mandibular hypoplasia, ocular epibulbar dermoid, and cervical vertebral malformations. Congenital heart defects (CHDs) have been reported in 5-58% of the patients. We analyze the frequency and anatomic features of CHD in a series of 87 patients with OAVS examined between January 1990 and February 2007 with normal chromosomes, ranging in age between 0.1 and 16.8 years. A twin pregnancy occurred in eight cases (dizygotic in six cases and monozygotic in two). CHDs were diagnosed in 28/87 (32%) patients, and classified into categories of postulated developmental mechanisms including 9 (32%) atrial and ventricular septal defects, 11 (39%) conotruncal defects, 4 (14%) targeted growth defects, two (7%) with situs and looping defects, one (4%) with a left-sided obstructive lesion and one (4%) with patent ductus arteriosus. As noted in other series, the most common individual CHDs were ventricular septal defect (six patients) and tetralogy of Fallot (TOF) (classic or with pulmonary atresia) (six patients). Comparing the frequencies of CHDs groups observed in the OAVS patients with the findings of the Emilia-Romagna Registry which ascertained CHDs prevalence in the general population, conotruncal defects, targeted growth defects, and heterotaxia were significantly associated with OAVS., (2008 Wiley-Liss, Inc.)

We report on three patients with Costello syndrome (CS) diagnosed during the first year of life and try to outline the clinical characteristics facilitating early recognition of this syndrome, which can now be corroborated by testing the HRAS gene. Phenotypical overlap of CS with Noonan (NS) and cardiofaciocutaneous syndrome (CFCS), particularly in neonatal age, is well known. Diagnostic features useful for recognition of CS in the first year of life are the following: (1) fetal and neonatal macrosomia with subsequent slow growth due to severe feeding difficulties, (2) developmental delay, (3) particularly coarse facial dysmorphisms and gingival hyperplasia, (4) skeletal anomalies as osteoporosis and metaphyseal enlargement, (5) hypertrophic cardiomyopathy (HCM) with asymmetric septal thickening and systolic anterior motion of the mitral valve, and (6) specific atrial arrhythmias. Following a clinical suspect of CS based on specific features, molecular screening of HRAS gene mutations should precede analysis of the other genes in the Ras-MAPK pathway implicated in related disorders with overlapping phenotypes.

The aim of this study was to characterize cardiovascular involvement in a large number of patients with LEOPARD syndrome. Twenty-six patients (age range 0 to 63 years, median age at the time of the study evaluation 17 years) underwent clinical and genetic investigations. Familial disease was ascertained in 9 patients. Nineteen patients (73%) showed electrocardiographic abnormalities. Left ventricular (LV) hypertrophy was present in 19 patients (73%), including 9 with LV outflow tract obstructions; right ventricular hypertrophy was present in 8 patients (30%). Valve (57%) and coronary artery (15%) anomalies were also observed. Single patients showed LV apical aneurysm, LV noncompaction, isolated LV dilation, and atrioventricular canal defect. During follow-up (9.1 +/- 4.5 years), 2 patients died suddenly, and 2 patients had cardiac arrest. These patients had LV hypertrophy. Despite the limited number of subjects studied, genotype-phenotype correlations were observed in familial cases. In conclusion, most patients with LEOPARD syndrome showed LV hypertrophy, often in association with other valvular or congenital defects. A spectrum of underrecognized cardiac anomalies were also observed. Long-term prognosis was benign, but the occurrence of 4 fatal events in patients with LV hypertrophy indicates that such patients require careful risk assessment and, in some cases, consideration for prophylaxis against sudden death.

LEOPARD syndrome (LS) is an autosomal dominant syndrome characterized by multiple lentigines and café-au-lait spots, electrocardiographic-conduction abnormalities, ocular hypertelorism/obstructive cardiomyopathy, pulmonary stenosis, abnormalities of the genitalia in males, retardation of growth, and deafness. LS shares many features with Noonan syndrome (NS), in which lentigines and deafness are usually not present. Molecular studies have shown that LS and NS are allelic disorders, caused by different missense mutations in PTPN11, a gene encoding the protein tyrosine phosphatase SHP-2 located at chromosome 12q22-qter. The clinical diagnosis of LS is generally difficult in the first months of life because the distinctive lentigines are generally not present at birth and develop during childhood. From January 2002 to December 2004, we suspected LS clinically in 10 patients admitted to our genetic counseling services in the first 12 months of life. A PTPN11 gene mutation was detected in 8/10 (80%) patients. In one patient without a PTPN11 mutation a subsequent clinical diagnosis of neurofibromatosis type 1 (NF1) was made, following the evaluation of the mother, who had previously undiagnosed classic NF1. The age of LS patients with PTPN11 mutation ranged between 1 and 11 months (mean age +/- SD 7.5 +/- 3.96 months). Review of the clinical characteristics of patients with LS confirmed by molecular study during the first year of life demonstrates that the diagnosis of LS in the first months of age can be clinically suspected in patients presenting with three main features, that is, characteristic facial features (100%), hypertrophic cardiomyopathy (HCM) (87%), and cafe-au-lait spots (75%). Characteristic facial features can be mild or severe, and consist of hypertelorism, downslanting palpebral fissures, ptosis, and dysmorphic ears. The clinical suspicion of LS may be confirmed by molecular screening for PTPN11 mutations. An early diagnosis of the disease is useful for the prospective care of associated medical problems and for precise genetic counseling., (Copyright 2006 Wiley-Liss, Inc.)

Familial recurrence of congenitally corrected transposition of the great arteries (CCTGA) is considered uncommon. Most of the previous familial studies involved a small number of patients and referred to all situs and looping anomalies including single ventricle, heterotaxia, and other cardiac defects different from CCTGA. We performed a large, consecutive clinical case series study in order to detect the recurrence of congenital heart defects in families of children with the classic form of CCTGA. From January 1997 through December 2004, 102 consecutive patients with CCTGA were evaluated in four institutions. There were 59 male (57.8%) and 43 female (42.2%). Mean age was 8.6 +/- 7.8 years. Eighty-eight patients (86.3%) had situs solitus of the atria, 14 (13.7%) situs inversus. The cardiac and extracardiac anomalies among relatives and the patterns of familial recurrence were investigated. Relatives with congenital heart defects were found in 16/102 families (15.7%). Transposition of the great arteries (TGA) was the most common recurrent defect (6/102 families). Consanguinity was identified in the parents of three probands. Six probands had an unaffected twin-sib. Recurrence risks for congenital heart defects were calculated at 5.2% (6/116) for siblings. In conclusion, CCTGA is not always sporadic in families. The pattern of inheritance, the presence of consanguinity among parents and the recurrence of situs inversus could suggest, in some families, an autosomal recessive mechanism with similarities with that occurring in some pedigrees with heterotaxia. The recurrence of TGA and CCTGA in the same family suggests a pathogenetic link between these two anatomically different malformations., ((c) 2005 Wiley-Liss, Inc.)
