The association between type 2 diabetes mellitus (T2DM) and heart failure (HF) has been firmly established; however, the entity of diabetic myocardial disorder (previously called diabetic cardiomyopathy) remains a matter of debate. Diabetic myocardial disorder was originally described as the occurrence of myocardial structural/functional abnormalities associated with T2DM in the absence of coronary heart disease, hypertension and/or obesity. However, supporting evidence has been derived from experimental and small clinical studies. Only a minority of T2DM patients are recognized as having this condition in the absence of contributing factors, thereby limiting its clinical utility. Therefore, this concept is increasingly being viewed along the evolving HF trajectory, where patients with T2DM and asymptomatic structural/functional cardiac abnormalities could be considered as having pre-HF. The importance of recognizing this stage has gained interest due to the potential for current treatments to halt or delay the progression to overt HF in some patients. This document is an expert consensus statement of the Heart Failure Association of the ESC and the ESC Working Group on Myocardial & Pericardial Diseases. It summarizes contemporary understanding of the association between T2DM and HF and discuses current knowledge and uncertainties about diabetic myocardial disorder that deserve future research. It also proposes a new definition, whereby diabetic myocardial disorder is defined as systolic and/or diastolic myocardial dysfunction in the presence of diabetes. Diabetes is rarely exclusively responsible for myocardial dysfunction, but usually acts in association with obesity, arterial hypertension, chronic kidney disease and/or coronary artery disease, causing additive myocardial impairment.

UNASSIGNED: The Witteveen-Kolk syndrome (WITKOS) (OMIM: 613406) is a heterogeneous emerging disorder caused by pathogenic variants or microdeletions encompassing the SIN3A gene (SIN3 Transcription Regulator Family Member A). It is characterized by distinctive facial features, developmental delay, intellectual disability, microcephaly, short stature, and subtle anomalies on brain magnetic resonance imaging (MRI). To date, about 50 patients have been reported in the medical literature.
UNASSIGNED: In this article, we reported a patient with classic findings of WITKOS including global developmental delay, microcephaly, hypotonia, vomiting, malnutrition, autistic and dysmorphic facial features, and cardiac abnormalities. Also, a barium esophagogram suggested severe motility disorder and gastroesophageal reflux disease. Affymetrix CytoScan 750K microarray showed a de novo 1.6-Mb deletion at 15q24.1q24.2, including the whole SIN3A gene. We have also summarized the clinical features of WITKOS patients in the medical literature and cardiac abnormalities detected in 4 out of 10 patients in studies that clearly state that cardiac examination was performed in the patients.
UNASSIGNED: Our findings showed that cardiac defects are not uncommon findings in WITKOS. Physicians should also be aware of reflux disease and motility disorder in patients with feeding difficulty together with early cardiac examination in terms of an improved quality of life in WITKOS patients.

UNASSIGNED: Scleroderma, also referred to as systemic sclerosis, is a multifaceted autoimmune condition characterized by abnormal fibrosis and impaired vascular function. Pathologically, it encompasses the persistent presence of inflammation, abnormal collagen buildup, and restructuring of blood vessels in various organs, resulting in a wide range of clinical symptoms. This review incorporates the most recent scientific literature on scleroderma, with a particular emphasis on its pathophysiology, clinical manifestations, diagnostic approaches, and treatment options.
UNASSIGNED: A comprehensive investigation was carried out on numerous databases, such as PubMed, MEDLINE, Scopus, Web of Science, and Google Scholar, to collect pertinent studies covering diverse facets of scleroderma research.
UNASSIGNED: Scleroderma presents with a range of systemic manifestations, such as interstitial lung disease, gastrointestinal dysmotility, Raynaud\'s phenomenon, pulmonary arterial hypertension, renal complications, neurological symptoms, and cardiac abnormalities. Serological markers, such as antinuclear antibodies, anti-centromere antibodies, and anti-topoisomerase antibodies, are important for classifying diseases and predicting their outcomes.
UNASSIGNED: The precise identification of scleroderma is crucial for promptly and correctly implementing effective treatment plans. Treatment approaches aim to improve symptoms, reduce complications, and slow down the progression of the disease. An integrated approach that combines pharmacological agents, including immunosuppressants, endothelin receptor antagonists, and prostanoids, with nonpharmacological interventions such as physical and occupational therapy is essential for maximizing patient care.
UNASSIGNED: Through the clarification of existing gaps in knowledge and identification of emerging trends, our goal is to improve the accuracy of diagnosis, enhance the effectiveness of therapeutic interventions, and ultimately enhance the overall quality of life for individuals suffering from scleroderma. Ongoing cooperation and creative research are necessary to advance the field and achieve improved patient outcomes and new therapeutic discoveries.

BACKGROUND: Limb-girdle muscular dystrophies (LGMDs) are a group of heterogeneous inherited diseases predominantly characterized by limb-girdle muscle weakness and dystrophic changes on histological analysis. The frequency of LGMD subtypes varies among regions in China and ethnic populations worldwide. Here, we analyzed the prevalence of LGMD subtypes, their corresponding clinical manifestations, and molecular data in a cohort of LGMD patients in Southeast China.
METHODS: A total of 81 consecutive patients with clinically suspected LGMDs from 62 unrelated families across Southeast China were recruited for targeted next-generation sequencing and whole-exome sequencing from July 2017 to February 2020.
RESULTS: Among 50 patients (41 families) with LGMDs, the most common subtypes were LGMD-R2/LGMD2B (36.6%) and LGMD-R1/LGMD2A (29.3%). Dystroglycanopathies (including LGMD-R9/LGMD2I, LGMD-R11/LGMD2K, LGMD-R14/LGMD2N and LGMD-R20/LGMD2U) were the most common childhood-onset subtypes and were found in 12.2% of the families. A total of 14.6% of the families had the LGMD-R7/LGMD2G subtype, and the mutation c.26_33dupAGGTGTCG in TCAP was the most frequent (83.3%). The only patient with the rare subtype LGMD-R18/LGMD2S had TRAPPC11 mutations; had a later onset than those previously reported, and presented with proximal‒distal muscle weakness, walking aid dependency, fatty liver disease and diabetes at 33 years of age. A total of 22.0% of the patients had cardiac abnormalities, and one patient with LMNA-related muscular dystrophy/LGMD1B experienced sudden cardiac death at 37 years of age. A total of 15.4% of the patients had restrictive respiratory insufficiency. Muscle imaging in patients with LGMD-R1/LGMD2A and LGMD-R2/LGMD2B showed subtle differences, including more severe fatty infiltration of the posterior thigh muscles in those with LGMD-R1/LGMD2A and edema in the lower leg muscles in those with LGMD-R2/LGMD2B.
CONCLUSIONS: We determined the prevalence of different LGMD subtypes in Southeast China, described the detailed clinical manifestations and distinct muscle MRI patterns of these LGMD subtypes and reported the frequent mutations and the cardiorespiratory involvement frequency in our cohort, all of which might facilitate the differential diagnosis of LGMDs, allowing more timely treatment and guiding future clinical trials.

UNASSIGNED: We present a large Indian series of Multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 (COVID-19) infection. The aim of the study is to present the incidence and pattern of cardiac involvement in children with MIS-C and their short-term follow-up.
UNASSIGNED: Consecutive 144 children younger than 18 years of age diagnosed with MIS-C referred for cardiac evaluation between June 1 and November 30, 2021, were included and were followed up till February 2022. In addition to the demographics, details of COVID-19 infection, and biomarkers, their cardiovascular assessment (echocardiogram and electrocardiogram) was documented at baseline and on follow-up. The median age of children with MIS-C was 60 (24-104) months. Abnormal cardiac imaging was noted in 59% of children. Ventricular dysfunction was noted in 13.9% and coronary abnormalities were noted in 25.7% of children. The median duration when the first cardiac abnormality was reported was 7 (5-10) days. The distribution of age categories between children with and without cardiac abnormality was comparable. Children with cardiac abnormalities were followed up for a median duration of 47 (30-58) days. Complete resolution was documented in 92% of children after a median duration of 20 (9-38) days. There were no readmissions or deaths during follow-up.
UNASSIGNED: Cardiac involvement in children with MIS-C is frequent with coronary abnormalities and ventricular dysfunction being the most common manifestations. Most children exhibit complete clinical and myocardial recovery with appropriate anti-inflammatory therapy. Studies on long-term outcome of these children are needed.

OBJECTIVE: To determine and predict the maternal and neonatal outcomes of pregnancies occurring in patients with cardiac disease.
METHODS: This retrospective review included 147 pregnancies identified from antenatal, delivery, and nursery records. Information concerning the nature and severity of the pre-existing cardiac disease, comorbidities, risk scores, obstetric or cardiac complications, and pregnancy outcomes were collected. The data were analyzed using SPSS Windows version 22.
RESULTS: In all, 111 (73.5%) of the cohort had acquired heart disease and 4 (2.7%) of patients belonged to WHO class IV, in which pregnancy is not recommended. Additionally, 12 (8.1%) were categorized as being at significant risk of having a cardiac complication. The proportion of patients that had maternal and perinatal mortality was 6 (4.0%) and 7 (4.8%), respectively. The WHO and CARPREG scoring systems were reliably able to predict cardiac events (P < 0.01). Mothers who received preconception counseling had significantly fewer occurrences of cardiac and obstetric events than those who did not.
CONCLUSIONS: Cardiac disease in pregnancy in women managed at our center was most often an acquired disease. The baseline risk assessment scores accurately predicted the likelihood of adverse cardiac outcomes.

As binary switches, RAS proteins switch to an ON/OFF state during signaling and are on a leash under normal conditions. However, in RAS-related diseases such as cancer and RASopathies, mutations in the genes that regulate RAS signaling or the RAS itself permanently activate the RAS protein. The structural basis of this switch is well understood; however, the exact mechanisms by which RAS proteins are regulated are less clear. RAS/MAPK syndromes are multisystem developmental disorders caused by germline mutations in genes associated with the RAS/mitogen-activated protein kinase pathway, impacting 1 in 1,000-2,500 children. These include a variety of disorders such as Noonan syndrome (NS) and NS-related disorders (NSRD), such as cardio facio cutaneous (CFC) syndrome, Costello syndrome (CS), and NS with multiple lentigines (NSML, also known as LEOPARD syndrome). A frequent manifestation of cardiomyopathy (CM) and hypertrophic cardiomyopathy associated with RASopathies suggest that RASopathies could be a potential causative factor for CM. However, the current supporting evidence is sporadic and unclear. RASopathy-patients also display a broad spectrum of congenital heart disease (CHD). More than 15 genes encode components of the RAS/MAPK signaling pathway that are essential for the cell cycle and play regulatory roles in proliferation, differentiation, growth, and metabolism. These genes are linked to the molecular genetic pathogenesis of these syndromes. However, genetic heterogeneity for a given syndrome on the one hand and alleles for multiple syndromes on the other make classification difficult in diagnosing RAS/MAPK-related diseases. Although there is some genetic homogeneity in most RASopathies, several RASopathies are allelic diseases. This allelism points to the role of critical signaling nodes and sheds light on the overlap between these related syndromes. Even though considerable progress has been made in understanding the pathophysiology of RASopathy with the identification of causal mutations and the functional analysis of their pathophysiological consequences, there are still unidentified causal genes for many patients diagnosed with RASopathies.

BACKGROUND: Congenital scoliosis(CS) is associated with multiple organs defect, and cardiac abnormalities have been reported commonly associated with CS. Hemivertebra is caused by the failure of vertebral formation, which is a major constitute of CS. Till now, few studies focus on the incidence and interrelationship of hemivertebra and concomitant cardiac abnormalities in congenital scoliosis. We aimed to analyze the cardiac defect in CS patients with or without hemivertebra, and further explore the incidence of cardiac defect between different types of hemivertebra.
METHODS: The ultrasonic cardiography (UCG) results of surgically treated congenital scoliosis (CS) patients between 2015 and 2018 were retrospectively analyzed. Patients were divided into hemivertebra group and non-hemivertebra group according to preoperative CT. Patients with hemivertebra was further divided into sub-group by single/multiple or fully/partially/mixed segmented hemivertebra. Demographic information, radiographic data and cardiac abnormalities were statistically compared between groups.
RESULTS: A total of 329 patients were analyzed, including 216 patients with hemivertebra and 113 patients without hemivertebra. UCG results were abnormal in 89 cases (27.1%), including 41 males(12.5%) and 48 females(14.6%). Hemivertebra group had comparable incidence of cardiac abnormalities with non-hemivertebra group (p = 0.517). No significant difference in the incidence of UCG abnormalities between single and multiple hemivertebra group (P = 0.246). Binary logistic regression analysis showed that female sex with multiple hemivertebra was a risk factor for abnormal UCG (P = 0.009, OR = 3.449). Cardiac abnormalities was comparable among fully, partially and mixed segmented hemivertebra group(P = 0.264). In abnormal UCG, 33 patients with hemivertebra had non-valvular abnormalities, and 48.5% (16/33) were septal defects. 28 patients had valvular abnormalities, most of them were mitral valve abnormalities, especially mitral valve redundancy, prolapse and insufficiency(82.1%, 23/28). No significant difference between the incidence of non-valvular and valvular abnormalities in patients with hemivertebra (P = 0.581).
CONCLUSIONS: The incidence of abnormal UCG results was approximately 28.2% in CS patients with hemivertebra. Female patients with multiple hemivertebra had a higher risk of UCG abnormalities. Mitral valve abnormalities were the most common abnormality of UCG found in CS patients with hemivertebra.
BACKGROUND: retrospectively registered.

UNASSIGNED: Cardiac complications of serious SARS-CoV-2 infections, especially Multisystem Inflammatory Syndrome of Children (MIS-C) are well described, however current studies have not considered pediatric patients hospitalized with no cardiac concerns. We established a protocol for cardiac evaluation of all admitted COVID-19 patients three weeks post-discharge, irrespective of cardiac concerns. We assessed cardiovascular outcomes and hypothesized that patients with absent cardiac concerns are at lower risk for cardiac abnormalities.
UNASSIGNED: This was a retrospective study of 160 patients admitted for COVID-19 (excluding MIS-C) between March 2020 and September 2021 with subsequent echocardiogram(s) performed at our center. Patients were divided into 4 subgroups: Group 1 included patients with absent cardiac concerns, admitted to acute care (1a) and intensive care unit (ICU) (1 b). Group 2 included patients with cardiac concerns, admitted to acute care (2a) and ICU (2 b). Groups were compared based on clinical endpoints and echocardiographic measurements, including tissue Doppler imaging (TDI) assessment of diastolic function (z-score of septal Mitral E/TDI E\' and lateral E/TDI E\'). Chi-squared, Fisher\'s exact, and Kruskal-Wallis tests were used.
UNASSIGNED: Traditional cardiac abnormalities varied significantly between the groups; with Group 2 b having the most (n = 8, 21%), but still found in Group 1a (n = 2, 3%) and Group 1 b (n = 1, 5%). No patients in Group 1 demonstrated abnormal systolic function, compared to Group 2a (n = 1, 3%) and Group 2 b (n = 3, 9%, p = 0.07). When including TDI assessment of diastolic function, the total incidence of abnormalities found on echocardiogram was increased in all groups.
UNASSIGNED: Cardiac abnormalities were found in pediatric patients admitted with COVID-19, even those without apparent cardiovascular concerns. The risk was greatest in ICU-admitted patients with cardiac concerns. The clinical significance of diastolic function assessment in these patients remains unknown. Further studies are needed to assess long-term cardiovascular sequelae of children with COVID-19, irrespective of cardiac concerns.

Omphalocele is the most common ventral abdominal wall defect. Omphalocele is associated with other significant anomalies in up to 80% of cases, among which the cardiac ones are the most frequent. The aim of our paper is to highlight, through a review of the literature, the importance and frequency of association between the two malformations and what impact this association has on the management and evolution of patients with these pathologies. We reviewed the titles, the available abstracts, and the full texts of 244 papers from the last 23 years, from three medical databases, to extract data for our review. Due to the frequent association of the two malformations and the unfavorable effect of the major cardiac anomaly on the prognosis of the newborn, the electrocardiogram and echocardiography must be included in the first postnatal investigations. The timing of surgery for abdominal wall defect closure is mostly dictated by the cardiac defect severity, and usually the cardiac defect takes priority. After the cardiac defect is medically stabilized or surgically repaired, the omphalocele reduction and closure of the abdominal defect are performed in a more controlled setting, with improved outcomes. Compared to omphalocele patients without cardiac defects, children with this association are more likely to experience prolonged hospitalizations, neurologic, and cognitive impairments. Major cardiac abnormalities such as structural defects that require surgical treatment or result in developmental delay will significantly increase the death rate of patients with omphalocele. In conclusion, the prenatal diagnosis of omphalocele and early detection of other associated structural or chromosomal anomalies are of overwhelming importance, contributing to the establishment of antenatal and postnatal prognosis.
