RESUMO

OBJECTIVE: To develop a cardiologic scoring system to predict mortality among geriatric coronavirus disease-2019 patients. METHODS: The retrospective cohort study was conducted after approval from the ethics review committee of the Dr Soetomo General Academic Hospital, Surabaya, Indonesia, and comprised data from March 1, 2020, to April 30, 2021, of geriatric patients of either gender confirmed for coronavirus disease-2019 from several referral hospitals in East Java, Indonesia. Data on comorbidities, electrocardiograph, and chest X-ray findings was examined to develop a comprehensive scoring system. Data was analysed using SPSS 26. RESULTS: Of the 3,893 cases reviewed, data of 322(8.27%) patients was analysed; 191(59.3%) males and 131(40.7%) females. The overall mean age was 66±4.1 years (range: 60-75 years). Of them, 267(82.9%) subjects were alive upon hospital discharge, while 55(17.1%) died during hospitalisation. Of the 24 variables analysed, 5(21%) were found to be significant: cardiomegaly, sinus tachycardia, ST-segment abnormalities, pathological T-wave inversions, and axis deviation (p<0.05). Receiver operating characteristic curve analysis showed an area under the curve 0.86, cut-off point ≤4 with sensitivity 89% and specificity 69%. CONCLUSIONS: The scoring system was found to have the potential to predict mortality in geriatric coronavirus disease-2019 patients based on cardiac findings during hospital admission.

RESUMO

Cardiomegaly is among the disorders categorized by a structural enlargement of the heart by any of the situations including pregnancy, resulting in damage to heart muscles and causing trouble in normal heart functioning. Cardiomegaly can be defined in terms of dilatation with an enlarged heart and decreased left or biventricular contraction. The genetic origin of cardiomegaly is becoming more evident due to extensive genomic research opening up new avenues to ensure the use of precision medicine. Cardiomegaly is usually assessed by using an array of radiological modalities, including computed tomography (CT) scans, chest X-rays, and MRIs. These imaging techniques have provided an important opportunity for the physiology and anatomy of the heart. This review aims to highlight the complexity of cardiomegaly, highlighting the contribution of both ecological and genetic variables to its progression. Moreover, we further highlight the worth of precise clinical diagnosis, which comprises blood biomarkers and electrocardiograms (EKG ECG), demonstrating the significance of distinguishing between numerous basic causes. Finally, the analysis highlights the extensive variation of treatment lines, such as lifestyle modifications, prescription drugs, surgery, and implantable devices, although highlighting the critical need for individualized and personalized care.

RESUMO

Thyroid storm is a rare yet critical complication of uncontrolled thyrotoxicosis, posing significant challenges in clinical management. We present the case of a 65-year-old African-American female with a medical history significant for untreated Graves' disease, hypertension, and diverticulosis, who presented with escalating abdominal pain, accompanied by nausea, vomiting, diarrhea, and chest discomfort. Upon admission, she exhibited atrial fibrillation with rapid ventricular response (RVR) and newly diagnosed high-output cardiac failure. Diagnosis of thyroid storm was confirmed through comprehensive laboratory assessments and clinical evaluation. Treatment with beta-blockers, anti-thyroid medications, and corticosteroids facilitated stabilization of her condition. This case report highlights the importance of early identification and intervention in thyroid storm to avert potential morbidity and mortality.

RESUMO

Ebstein anomaly (EA) is a rare congenital heart defect characterized by abnormal development of the tricuspid valve (TV) and right ventricular myocardium. This study documents 2 dramatic cases of fetal EA characterized by hydrops and cardiomegaly, leading to intrauterine or early neonatal death. These clinical outcomes were associated with morphological abnormalities including severe tricuspid regurgitation, unguarded TV orifice, pulmonary atresia, and flattened right ventricular myocardium. This study highlights that these adverse anatomical features may result in unfavorable clinical outcomes in fetal EA. While timely identification of such features by prenatal ultrasound is crucial for providing accurate prognostic stratification and guiding treatment decisions, fetopsy may be necessary to discern EA among the spectrum of right-heart anomalies.

RESUMO

Introduction: The advancement of surgical techniques and perioperative management for congenital heart disease (CHD) has increased life expectancy. The surgical creation of the Fontan circulation maintains pulmonary blood flow without relying on an effective pump from the abnormal heart, relying on peripheral vascular resistance to maintain effective flow through the lungs. Unfortunately, this delicate mechanism is compromised when scoliosis restricts ventilation, leading to Fontan failure and a poor prognosis for life. This report describes the prevalence of scoliosis with Fontan completion surgery and the role of screening and surgical correction. Methods: Ninety-six consecutive Japanese patients undergoing Fontan completion surgery for CHD between 2000 and 2017 were identified in our institutional records. The inclusion criterion was at least 7 years of follow-up after Fontan completion surgery, while the exclusion criteria were congenital, syndromic, and neuromuscular scoliosis. Radiographic and clinical parameters, including cardio-thoracic ratio (CTR) for cardiomegaly and cyanosis saturation, were compared between with and without scoliosis. Results: There were 23 and 40 patients in the scoliosis and no scoliosis groups, respectively. The mean age at the final follow-up was 18.5 and 16.7 years in the scoliosis and no scoliosis groups, respectively (p=0.02). Mean CTR was 43.7% and 39.4% in the scoliosis and no scoliosis groups (p=0.016), and the mean saturation in room air at the final follow-up was 88.8% and 93.2%, respectively (p=0.036). There were no significant differences to clarify the risk factors with multivariate logistic regression analysis. Conclusions: The prevalence of scoliosis with Fontan completion surgery was 36.5%. Screening for scoliosis is important for children with Fontan circulation surgery as part of their routine follow-up at least until they reach adolescence.Evidence Level: 4.

RESUMO

The successful integration of neural networks in a clinical setting is still uncommon despite major successes achieved by artificial intelligence in other domains. This is mainly due to the black box characteristic of most optimized models and the undetermined generalization ability of the trained architectures. The current work tackles both issues in the radiology domain by focusing on developing an effective and interpretable cardiomegaly detection architecture based on segmentation models. The architecture consists of two distinct neural networks performing the segmentation of both cardiac and thoracic areas of a radiograph. The respective segmentation outputs are subsequently used to estimate the cardiothoracic ratio, and the corresponding radiograph is classified as a case of cardiomegaly based on a given threshold. Due to the scarcity of pixel-level labeled chest radiographs, both segmentation models are optimized in a semi-supervised manner. This results in a significant reduction in the costs of manual annotation. The resulting segmentation outputs significantly improve the interpretability of the architecture's final classification results. The generalization ability of the architecture is assessed in a cross-domain setting. The assessment shows the effectiveness of the semi-supervised optimization of the segmentation models and the robustness of the ensuing classification architecture.

RESUMO

Aortocardiac fistula is a broad term used to describe defects between the aorta and other cardiac chambers that can occur in humans and animals. A 1.5-year-old, 1.7 kg, male castrated Holland lop rabbit (Oryctolagus cuniculus) was presented for a two-week history of a heart murmur with corresponding cardiomegaly on radiographs. Physical examination confirmed a grade-V/VI continuous heart murmur on the right sternal border with a regular rhythm and a gallop sound. Echocardiography revealed an aortic-to-right-atrial fistula causing severe left-sided volume overload. Based on the echocardiographic findings, rupture of the right aortic sinus was suspected. Due to the poor prognosis, euthanasia was elected. On necropsy, a fistula was found connecting the right aortic sinus with the right atrium, without evidence of an inflammatory response nor evidence of an infectious etiology. The sudden onset of a heart murmur supported acquired fistulation from a ruptured aortic sinus (also known as the sinus of Valsalva), though a congenital malformation could not be completely excluded.

RESUMO

Ellis-van Creveld syndrome (EVC), also known as chondroectodermal dysplasia, is a rare entity. It most commonly affects the tubular bones leading to dwarfism and a long trunk with ossification defects. Other presentations are wide hands and feet, dysplastic nails, thin hair, and cardiac malformations. An eight-year-old female patient presented to our tertiary care centre with complaints of short stature, abnormal dentition, and fatigue. The child's parents were first-degree relatives. On radiological imaging, it was revealed that the patient had postaxial polydactyly, short stature, and genu valgum deformity along with mild cardiomegaly. All these features were indicative of Ellis-van Creveld syndrome. EVC is a rare clinical syndrome with a distinctive clinical presentation. It requires comprehensive radiological investigations and the management is best done with a multidisciplinary approach.

RESUMO

Pulmonary arteriovenous malformations (AVMs) are abnormal connections between the pulmonary arteries and veins that can result in rapid-onset heart failure. We present a case of a fetus with pulmonary AVMs diagnosed at 22 weeks gestation. Fetal echocardiography showed cardiomegaly and dilated pulmonary arteries and veins reflecting the hemodynamic significance of the shunt. Inverted flow through the ductus arteriosus was also present. Fetal autopsy following medical termination of the pregnancy confirmed the morphological findings, including displacement of arteries and veins in proximity to the pleural surface. The genetic study was negative. This report highlights the cardiovascular impact of a rare disorder. Inverted flow through the ductus arteriosus may be another poor prognostic indicator, useful in parental counseling.

RESUMO

Iron deficiency anaemia (IDA) is common in children. Treatment usually consists of oral iron therapy and, if severe, inpatient hospitalisation with blood transfusion. Providers may also undertake an echocardiogram, depending on availability and the severity of anaemia. A male toddler with nutritional IDA, haemoglobin of 1.7 g/dL (the lowest level in the literature) and hypertension had left ventricular hypertrophy (LVH) on the initial echocardiogram. He was managed acutely with judicious blood transfusion, followed by oral iron supplementation and anti-hypertensive medication at discharge. Repeat echocardiogram a month later demonstrated slight improvement of the LVH but the hypertension persisted at follow-up 6 months later. There was complete resolution of the findings a year later. In chronic nutritional IDA, there can be structural cardiac changes which can affect the acute management and requires close follow-up. It is important to use echocardiography in such severe cases.Abbreviations: CHF: congestive heart failure; CM: cardiomyopathy; DCM: dilated cardiomyopathy; ICU: intensive care unit; IDA: iron deficiency anaemia; IVSd: interventricular septum in diastole; LA: left atrium; LV: left ventricle; LVEDD: left ventricular end-diastolic diameter; LVH: left ventricular hypertrophy; LVM: left ventricular mass; LVPWd: left ventricular posterior wall end-diastole; PRBC: packed red blood cells.

RESUMO

ABSTRACT Objective: Pediatric cardiac tumors are rare and, among them, 90% are benign. Cardiac fibroma is the second most frequent tumor, after rhabdomyoma. The objective of this study is to report a case of cardiac fibroma diagnosed incidentally in a patient admitted with acute viral bronchiolitis. Case description: A 5-month-old male infant was admitted to the pediatric emergency department with acute viral bronchiolitis requiring hospitalization. He presented a detectable respiratory syncytial virus in oropharyngeal swab, blood test with lymphocytosis and a chest radiography revealed cardiomegaly. Further cardiologic testing was performed detecting elevation of cardiac biomarkers, an electrocardiogram with alteration of left ventricular repolarization and echocardiogram with a heterogeneous mass in the left ventricular, with areas of calcification. A chest angiotomography suggested rhabdomyosarcoma or cardiac fibroma and a magnetic resonance showed a mass, with characteristics suggesting fibroma. The final diagnosis was made after two cardiac catheterizations for biopsy of the lesion, confirming cardiac fibroma by anatomopathological examination. Because the patient had moderate to severe systolic dysfunction, he was submitted to heart transplant. Comments: One third of cardiac fibromas are asymptomatic, generally diagnosed late through tests ordered for other reasons. The gold-standard test for definitive diagnosis is biopsy. Cardiac fibroma usually does not present spontaneous regression and, in most cases, partial or total surgical resection is necessary. When tumors are unresectable, heart transplantation should be indicated. It is essential to have detailed characterization of the cardiac mass to establish the most appropriate therapeutic approach for each patient.


RESUMO Objetivo: Tumores cardíacos pediátricos são raros e, entre eles, 90% são benignos. O fibroma cardíaco é o segundo mais frequente, após o rabdomioma. O objetivo deste trabalho é relatar um caso de fibroma cardíaco, cujo diagnóstico foi incidental em um paciente internado por bronquiolite viral aguda. Descrição do caso: Lactente do sexo masculino com cinco meses foi atendido em um pronto atendimento pediátrico com quadro de bronquiolite viral aguda, necessitando de hospitalização. Em exames complementares, apresentou vírus sincicial respiratório detectável, hemograma com linfocitose, além de radiografia de tórax com cardiomegalia. Em investigação cardiológica, as enzimas cardíacas encontravam-se elevadas, o eletrocardiograma apresentava alteração de repolarização de parede lateral de ventrículo esquerdo e o ecocardiograma demonstrou massa heterogênea em ventrículo esquerdo, com áreas de calcificação. A angiotomografia de tórax sugeriu rabdomiossarcoma ou fibroma cardíaco e a ressonância magnética demonstrou massa cuja localização e características sugeriram fibroma. O diagnóstico foi conclusivo após dois cateterismos para biópsia da lesão, confirmando fibroma cardíaco pelo anatomopatológico. Em razão da disfunção sistólica moderada a grave, o paciente foi submetido a transplante cardíaco. Comentários: Um terço dos fibromas cardíacos é assintomático, geralmente diagnosticado tardiamente por meio de exames solicitados por outro motivo. O padrão-ouro para o diagnóstico definitivo é a biópsia. O fibroma cardíaco não costuma apresentar regressão espontânea, sendo submetido, na maioria dos casos, a ressecção cirúrgica parcial ou total. Nos tumores irressecáveis, o transplante cardíaco deve ser indicado. A caracterização detalhada da massa cardíaca é fundamental para traçar a conduta terapêutica mais adequada para cada paciente.

RESUMO

BACKGROUND: Exercise-induced cardiac remodeling can be profound, resulting in clinical overlap with dilated cardiomyopathy, yet the significance of reduced ejection fraction (EF) in athletes is unclear. The aim is to assess the prevalence, clinical consequences, and genetic predisposition of reduced EF in athletes. METHODS: Young endurance athletes were recruited from elite training programs and underwent comprehensive cardiac phenotyping and genetic testing. Those with reduced EF using cardiac magnetic resonance imaging (defined as left ventricular EF <50%, or right ventricular EF <45%, or both) were compared with athletes with normal EF. A validated polygenic risk score for indexed left ventricular end-systolic volume (LVESVi-PRS), previously associated with dilated cardiomyopathy, was assessed. Clinical events were recorded over a mean of 4.4 years. RESULTS: Of the 281 elite endurance athletes (22±8 years, 79.7% male) undergoing comprehensive assessment, 44 of 281 (15.7%) had reduced left ventricular EF (N=12; 4.3%), right ventricular EF (N=14; 5.0%), or both (N=18; 6.4%). Reduced EF was associated with a higher burden of ventricular premature beats (13.6% versus 3.8% with >100 ventricular premature beats/24 h; P=0.008) and lower left ventricular global longitudinal strain (-17%±2% versus -19%±2%; P<0.001). Athletes with reduced EF had a higher mean LVESVi-PRS (0.57±0.13 versus 0.51±0.14; P=0.009) with athletes in the top decile of LVESVi-PRS having an 11-fold increase in the likelihood of reduced EF compared with those in the bottom decile (P=0.034). Male sex and higher LVESVi-PRS were the only significant predictors of reduced EF in a multivariate analysis that included age and fitness. During follow-up, no athletes developed symptomatic heart failure or arrhythmias. Two athletes died, 1 from trauma and 1 from sudden cardiac death, the latter having a reduced right ventricular EF and a LVESVi-PRS >95%. CONCLUSIONS: Reduced EF occurs in approximately 1 in 6 elite endurance athletes and is related to genetic predisposition in addition to exercise training. Genetic and imaging markers may help identify endurance athletes in whom scrutiny about long-term clinical outcomes may be appropriate.

RESUMO

Left atrial appendage aneurysm (LAAA) is an extremely rare congenital heart abnormality, with varying degrees of symptoms, ranging from asymptomatic to arrhythmia, thromboembolic event or airway obstruction. Most infantile cases were incidentally found by echocardiography. Contrast-enhanced chest tomography can confirm the diagnosis and inform surgical plan. We describe an asymptomatic young female infant who had a unique extreme cardiomegaly on a chest x-ray and received surgical aneurysmectomy. Her heart was restored to a normal cardiac size after the heart surgery.

RESUMO

BACKGROUND: Cantu syndrome is a rare and complex multisystem disorder characterized by hypertrichosis, facial dysmorphism, osteochondroplasia and cardiac abnormalities. With only 150 cases reported worldwide, Cantu syndrome is now gaining wider recognition due to molecular testing and a growing body of literature that further characterizes the syndrome and some of its most important features. Cardiovascular pathology previously described in the literature include cardiomegaly, pericardial effusion, vascular dilation and tortuosity, and other congenital heart defects. However, cardiovascular involvement is highly variable amongst individuals with Cantu syndrome. In some instances, it can be extensive and severe requiring surgical management and long term follow up. CASE PRESENTATION: Herein we report a case of a fourteen-year-old female who presented with worsening pericardial effusion of unknown etiology, and echocardiographic findings of concentric left ventricular hypertrophy, a mildly dilated aortic root and ascending aorta. Her medical history was notable for hemoptysis and an episode of pulmonary hemorrhage secondary to multiple aortopulmonary collaterals that were subsequently embolized in early childhood. She was initially managed with Ibuprofen and Colchicine but continued to worsen, and ultimately required a pericardial window for the management of refractory pericardial effusion. Imaging studies obtained on subsequent visits revealed multiple dilated and tortuous blood vessels in the head, neck, chest, and pelvis. A cardiomyopathy molecular studies panel was sent, and a pathogenic variant was identified in the ABCC9 gene, confirming the molecular diagnosis of autosomal dominant Cantu syndrome. CONCLUSIONS: Vascular anomalies and significant cardiac involvement are often present in Cantu syndrome, however there are currently no established screening recommendations or surveillance protocols in place. The triad of hypertrichosis, facial dysmorphism, and unexplained cardiovascular involvement in any patient should raise suspicion for Cantu syndrome and warrant further investigation. Initial cardiac evaluation and follow up should be indicated in any patient with a clinical and/or molecular diagnosis of Cantu syndrome. Furthermore, whole body imaging should be utilized to evaluate the extent of vascular involvement and dictate long term monitoring and care.

RESUMO

BACKGROUND: ACVIM developed and published guidelines for staging myxomatous mitral valve degeneration in dogs in 2009. An updated version was published in 2019. The present study aimed to investigate whether these guidelines are actually used by the intended public more than a decade after their first publication. METHODS: An online survey was distributed among Dutch and Belgian veterinarians through online channels and mailing lists. RESULTS: Of the 524 responses, only 363 complete surveys were analyzed. The ACVIM guidelines are used by 60% of the respondents. Veterinarians find it more difficult to differentiate stage B1 from B2 in asymptomatic dogs compared to diagnosing stage C. Three-quarters of the respondents would recommend echocardiography for an incidentally detected new murmur with an intensity of 3 out of 6 in an adult dog. Two-thirds of the respondents find coughing a convincing finding for stage C disease. Close to half of the respondents associate a horizontal, dull percussion line with pulmonary edema. For confirming cardiogenic pulmonary edema, 98% of the respondents used thoracic radiographs. CONCLUSIONS: Veterinary practitioners might not have the expected training and equipment to be able to apply the guidelines in their practices, especially in the differentiation of stage B1 from stage B2.
