Profile of Cardiac Involvement in Children After Exposure to COVID-19

Objective: To evaluate the incidence and pattern of cardiac involvement in children postCOVID (coronavirus disease) infection in a tertiary care referral hospital in India. Methods: A prospective observational study was conducted including all consecutive children with suspected MIS-C referred to the cardiology services. Results: Of the 111 children with mean (SD) age 3.5 (3.6) years, 95.4% had cardiac involvement. Abnormalities detected were coronary vasculopathy, pericardial effusion, valvular regurgitation, ventricular dysfunction, diastolic flow reversal in aorta, pulmonary hypertension, bradycardia and intracardiac thrombus. The survival rate post treatment was 99%. Early and short-term follow-up data was available in 95% and 70%, respectively. Cardiac parameters improved in the majority. Conclusion: Cardiac involvement post COVID-19 is often a silent entity and may be missed unless specifically evaluated for. Early echocardiography aids in prompt diagnosis, triaging, and treatment, and may help in favorable outcomes.

Poliarteritis nodosa sistémica / Systemic polyarteritis nodosa

Resumen La poliarteritis nodosa sistémica de inicio en la infancia es una vasculitis caracterizada por inflamación y necrosis fibrinoide de las arterias de mediano y pequeño calibre, con cuadro clínico extraordinariamente variable y dependiente de la localización histológica de la lesión. Su compromiso cardiaco constituye un comportamiento infrecuente en pediatría, por lo que se considera de interés presentar el caso de un escolar de 8 años, determinado por compromiso hemodinámico secundario a derrame pericárdico, disfunción sistólica grave y múltiples dilataciones aneurismáticas, que permite establecer la sospecha de vasculitis de vasos pequeños y medianos. Se realiza un diagnóstico oportuno gracias al cual se evitan complicaciones potencialmente mortales y se instaura un tratamiento con buena respuesta a corto, mediano y largo plazo.

Abstract Systemic polyarteritis nodosa of childhood onset is a vasculitis characterized by inflammation and fibrinoid necrosis in the medium and small-caliber arteries, with an extraordinarily variable clinical picture and dependent on the histological location of the lesion. His cardiac involvement constitutes an infrequent behavior in pediatrics, so it is considered of interest to present the case of an 8-year-old schoolboy, characterized by hemodynamic compromise secondary to pericardial effusion, severe systolic dysfunction, and multiple aneurysmal dilatations that establish the suspicion of vasculitis. small and medium glasses. A timely diagnosis is made avoiding life-threatening complications and allowing to establish a treatment with a good response in the short, medium and long term.

Successful Surgical Treatment of Coronary Aneurysm, Ascending Aortic Aneurysm, and Bicuspid Aorta for a Kawasaki Disease Patient

Abstract Kawasaki disease was first reported in 1967, and it was classified as an autoimmune vasculitis of the small and medium arteries. It is a self-limiting condition that occurs mostly in childhood, but it may involve complications — such as coronary artery aneurysms, myocardial ischemia, and arrhythmias — with significant morbidity and mortality that occur later in life. In this article, we present the association of an ascending aortic aneurysm with bicuspid aortic disease in addition to coronary aneurysm in a 55-year-old patient diagnosed with Kawasaki disease.

Giant Left Anterior Descending Coronary Artery Aneurysm in a Patient with Behçet's Disease

ABSTRACT Coronary artery involvement is quite rare in the course of Behçet's disease. Complications secondary to coronary artery aneurysms, including rupture, dissection, and myocardial ischemia, may be fatal. In young patients without cardiovascular risk factors, systemic inflammatory vasculitis syndromes should be investigated in case of acute coronary syndrome secondary to dilated coronary arteries. In this report, we present our management strategy in a 31-year-old male patient with Bechet's disease.

Nonatherosclerotic Giant Right Coronary Artery Aneurysm

Abstract We present an unusual case of a 67-year-old woman with an incidental finding of a cardiac mass on a chest computed tomography. Coronary angiotomography confirmed the diagnosis of right coronary artery aneurysm, with 5.7×5.7 cm. The patient underwent aneurysm resection and coronary bypass surgery, with subsequent histologic study suggestive of arteritis sequelae. Giant coronary artery aneurysms have a high risk of complications and aneurysm exclusion must be beneficial. This is a rare condition that can also be part of a systemic inflammatory disease.

Aneurisma de arteria coronaria derecha y elevación del segmento ST en cara inferior. Reporte de caso y revisión de la literatura / Right Coronary Artery Aneurysm and inferior ST segment elevation. Case Report and Literature Review / Aneurisma de artéria coronária direita e elevação do segmento ST na cara inferior. Reporte de caso e revisão da literatura

Los aneurismas de las arterias coronarias (AAC) son poco comunes, con una incidencia de 0.3-5.3%. Se definen como una dilatación 1.5 veces mayor al diámetro interno de la arteria normal adyacente. La arteria coronaria derecha es la más comúnmente afectada. Su fisiopatología es poco clara, pero se cree que una de sus principales causas es la aterosclerosis. Los AAC son generalmente asintomáticos o pueden estar asociados a isquemia miocárdica. Su tratamiento aún no está bien establecido, debido al desconocimiento general sobre su historia natural, e incluye desde un manejo conservador hasta el tratamiento quirúrgico. A continuación, se reporta el caso de un paciente con infarto agudo de miocardio y elevación del segmento ST, llevado a coronariografía que evidenció aneurisma de la coronaria derecha, que requirió trombectomía, angioplastia y manejo médico vitalicio ambulatorio.

Coronary artery aneurysms (CAA) are a rare entity with an incidence of 0.3-5.3%. They are dilations of 1.5 times larger than normal adjacent artery, with the right coronary artery as the most affected vessel. Its pathophysiology is unclear but atherosclerosis is believed to be the main cause. CAA are generally asymptomatic but can cause coronary ischemia. Its treatment is yet to be established due to general ignorance about its nature. It ranges from conservative management to surgery. In the following text, we report a case of a patient with acute myocardial infarction presenting ST-segment elevation, who showed a right coronary artery aneurysm in coronary angiography. The patient required thrombectomy, angioplasty and subsequent lifetime outpatient medical management.

Advances in Kawasaki disease combined with giant coronary aneurysm / 国际儿科学杂志

Kawasaki disease coronary artery lesions have become one of the common acquired cardiovascular diseases in children in some countries and regions.Giant coronary artery aneurysms are a severe type of Kawasaki disease coronary artery lesion with less likelihood of complete recovery at a later stage, and their cardiovascular event rate and mortality are significantly higher than those of other children with Kawasaki disease.Children with giant coronary aneurysms are at higher risk of cardiovascular disease in adulthood and are closely associated with sudden cardiac death in young adulthood and the development of coronary atherosclerosis in adulthood, with serious implications for the long-term prognosis and quality of life of the child.This article reviews the clinical features and prognosis of Kawasaki disease combined with giant coronary aneurysms.

Oblivion: autopsy findings of a 31-year-old man with sudden cardiac arrest, a case report of a sequalae of Kawasaki disease

ABSTRACT A 31-year-old man presented to the hospital after suffering a sudden cardiac arrest. Despite optimal therapy, the patient passed away. His medical history included febrile rash at age 2. At autopsy, there was aneurysmal dilation and severe coronary artery stenosis by atherosclerotic plaques and myocardial fibrosis. These findings were presumed to be due to complications of Kawasaki disease, given the remote history of severe febrile rash as a toddler and the presence of chronic coronary artery injury, recanalization, and thrombosis with ischemic heart disease leading to sudden cardiac collapse and death.

Coronary artery lesions in infants younger than 6 months with Kawasaki disease: clinical characteristics and prognosis / 中国小儿急救医学

Objective:To analyze the characteristics of coronary artery lesions in infants under 6 months of age with Kawasaki disease(KD), and to explore their regression and risk factors.Methods:The clinical data of 61 infants with KD[34 boys, 24 girls, aged 2.2 (1.7, 3.1) months] admitted to the department of critical care medicine and neonatology, Children′s Hospital, Capital Institute of Pediatrics from October 2015 to February 2020 were retrospectively analyzed.Persistent coronary artery aneurysm(CAA)was defined as the persistent enlargement of coronary arteries(coronary Z-score≥2.5)on echocardiograms at 12 months after KD onset.Cox proportional hazards mode was conducted to evaluate the potential risk factors of persistent CAA.Results:The incidence of CAA in 61 infants with KD was 52.5% (32/61) and occurred on 5 (4, 8)d of the disease course.During a follow-up of 547 (399, 782)d, five(8.2%, 5/61)infants satisfied the definition of persistent CAA.The median recovery time of CAA was 20 (12, 82)d after KD onset.Cox proportional hazards mode revealed that the maximal coronary Z-score was an independent factor of CAA regression( HR=0.451, 95% CI 0.293-0.694, P<0.001). Receiver operating characteristic curve analysis showed that the best cutoff value of coronary Z-score for predicting persistent CAA was 6.15(sensitivity 80.0%, specificity 97.7%). Conclusion:CAA is common in infants younger than 6 months with KD.The maximal coronary Z-score is an independent factor of persistent CAA.

Un caso de aneurisma coronario gigante en enfermedad de Kawasaki / A case of a giant coronary aneurysm in Kawasaki disease

La enfermedad de Kawasaki es una vasculitis que afecta arterias de mediano calibre que ocurre predominantemente en la población pediátrica, de etiología desconocida. Si no es tratada tempranamente existe riesgo de desarrollo de complicaciones tan severas como el desarrollo de aneurismas de arterias coronarias, las cuales pueden estar relacionadas con el desarrollo de trombosis coronaria y riesgo de infarto de miocardio. Se han asociado diversos factores de riesgo de desarrollo de aneurismas coronarios como el tiempo de evolución de la enfermedad o la edad del paciente, la importancia de la identificación de estos factores radica en la posibilidad de la pronta acción sobre aquellos que sean modificables en un intento de limitar el desarrollo de dichas complicaciones coronarias. El tratamiento a largo plazo para esta condición incluye terapia antiagregante y anticoagulante, ambas pueden representar un riesgo en sí mismas para el paciente además de ser limitantes para un paciente pediátrico por el riesgo de sangrado asociado a traumas (propios de la edad pediátrica).

Kawasaki disease is a vasculitis that affects medium-caliber arteries that occurs predominantly in the pediatric population, of unknown etiology. If it is not treated early, there is a risk of developing complications as severe as the development of coronary artery aneurysms, which may be related to the development of coronary thrombosis and the risk of myocardial infarction. Various risk factors have been associated with the development of coronary aneurysms such as the time of evolution of the disease or the age of the patient, the importance of identifying these factors lies in the possibility of prompt action on those that are modifiable in an attempt to limit the development of coronary complications. Long-term treatment for this condition includes antiplatelet and anticoagulant therapy, both may represent a risk in themselves for the patient as well as being limiting for a pediatric patient due to the risk of bleeding associated with trauma (typical of pediatric age).

Adenitis cervical imitando a un absceso cervical bacteriano en un lactante con Enfermedad de Kawasaki incompleta y aneurisma coronario: Reporte de un caso / Cervical adenitis mimicking a bacterial cervical abscess in an infant with incomplete Kawasaki disease and coronary aneurysm: A case repor

Antecedentes: La enfermedad de Kawasaki (EK) es una vasculitis aguda y autolimitada frecuente en menores de cinco años; sin embargo, su diagnóstico es un reto en menores de seis meses. Reporte de caso: Reportamos un lactante de tres meses con fiebre y tumoración cervical dolorosa de tres días de enfermedad. Fue diagnosticado como tumoración cervical abscedada y recibió tratamiento con antibióticos por 10 días. En hospitalización presentó lesiones eritematosas maculares en todo el cuerpo, persistencia de fiebre y elevación de marcadores inflamatorios. Se realizó una ecocardiografía encontrándose dilatación de las arterias coronarias siendo diagnosticado de EK incompleto. Recibió inmunoglobulina humana endovenosa y ácido acetil salicílico. Actualmente está en controles por cardiología con ácido acetil salicílico por persistencia de dilatación de las arterias coronarias. Conclusiones: La adenitis cervical puede imitar a otras infecciones cutáneas como el absceso cervical ocasionado retraso en el diagnóstico de EK produciendo complicaciones como el aneurisma coronario.

Background: Kawasaki disease (KD) is an acute and self-limited vasculitis common in children under five years. The diagnosis is a challenge in children under six months of age. Report case: We report a three-month-old infant with fever and a painful neck tumor of three days of disease. He was diagnosed with an abscessed cervical mass and received antibiotic treatment for ten days. During hospitalization, macular erythematous lesions developed throughout the body, persistence of fever, and elevated inflammatory markers. Echocardiography was performed, finding dilatation of the coronary arteries, being diagnosed with incomplete KD. He received intravenous human immunoglobulin and acetylsalicylic acid. He is currently undergoing cardiology controls with acetylsalicylic acid due to persistent dilatation of the coronary arteries. Conclusions: Cervical adenitis can mimic other skin infections such as cervical abscesses. It can cause a delay in the diagnosis of KD, producing complications such as a coronary aneurysm.

Slow Flow Phenomenon Impairs the Prognosis of Coronary Artery Ectasia as Well as Coronary Atherosclerosis

Abstract Introduction: Coronary artery ectasia (CAE) is one of the uncommon cardiovascular disorders and its prognosis is still debated. Objective: We aimed to review long-term follow-up data in patients with CAE and to evaluate the prognosis of CAE patients with coronary slow flow phenomenon (CSFP). Methods: This study had a prospective design and 143 patients with CAE were included. The angiographic and demographic characteristics were reviewed in detail. The patients were categorized, based on concomitant coronary artery stenosis detected by angiography, as CCAE group (n=87, ≥30% luminal stenosis) and ICAE group (n=56, <30% luminal stenosis) and also categorized by the coronary flow as CSFP group (n=51) and normal flow coronary ectasia - NCEA group (n=92). All patients were re-evaluated at 6-month intervals. Follow-up data, cardiovascular (CV) mortality, hospitalization and major adverse cardiac events (MACE) were collected. The level of statistical significance was set at 5%. Results: Patients were followed up for an average of 56.9±7.4 months. During the follow-up, statistically significant differences were found in hospitalization, CV mortality and MACE between the CCAE and ICAE groups (P=0.038, P=0.003, P=0.001, respectively). The CSFP and NCEA groups were also compared. There was a statistical difference with respect to hospitalization between the CFSP and NCEA groups (P=0.001), but no difference was observed in terms of MACE and CV mortality (P=0.793 and P=0.279). Conclusion: CSFP accompanying CAE may be a predictor of hospitalization. Significant atherosclerotic plaques coexisting with CAE may be predictive for MACE.

Surgical Treatment for a Super-Giant Right Coronary Artery Aneurysm Induced by Kawasaki Disease

Abstract A 32-year-old man diagnosed with Kawasaki disease at the age of three years presented with coronary artery aneurysm (CAA). The aneurysm increased in size, and the patient was referred to our hospital for surgery. Preoperative computed tomography scan showed a super-giant right CAA and giant left CAAs; surgery was performed. The super-giant right CAA was resected, and the ostium of the right coronary artery was closed; then, coronary artery bypass grafting was performed. The left CAAs were not treated surgically because the risk of rupture was low. Here, we describe the successful surgical treatment of a right super-giant CAA.

Enfermedad de Kawasaki: ¿una entidad exclusiva de niños? / Kawasaki disease, is it exclusive of children?

Resumen La enfermedad de Kawasaki es un síndrome febril agudo y autolimitado, de presunta etiología autoinmune, que característicamente afecta a niños menores de 5 años. Esta enfermedad consiste en una vasculitis aguda de pequeños y medianos vasos que favorece la formación de aneurismas en las arterias coronarias. El diagnóstico en la fase aguda es esencialmente clínico, mientras que en la fase crónica suele hacerse al documentar las secuelas vasculares. La importancia de la identificación apropiada de esta enfermedad radica en que muchos de los infartos fatales y no fatales en personas menores de 40 años tienen hallazgos compatibles con este diagnóstico. Se presenta el caso de un adulto joven con dolor torácico y angiotomografía coronaria con hallazgos compatibles con secuelas de enfermedad de Kawasaki del adulto.

Abstract Kawasaki disease is an acute and self-limited febrile syndrome with a presumed autoimmune etiology that characteristically affects children under 5 years of age. Kawasaki disease is an acute vasculitis of small and medium vessels that facilitates the formation of coronary aneurysms. The diagnosis of the disease during the acute phase is essentially clinical, while the diagnosis of Kawasaki disease during the chronic phase is performed when the vascular complications are detected. The importance of proper identification of Kawasaki disease lies in the fact that many of the fatal and non-fatal infarcts in young adults (<40 years) have findings compatible with this diagnosis. This article describes the case of a young patient with chest pain and coronary angiotomography showing sequelae of Kawasaki disease in the adult.

A Associação da Relação Proteína C-Reativa/Albumina em Pacientes com Ectasia da Artéria Coronária Isolada / Association of C-Reactive Protein to Albumin Ratio in Patients with Isolated Coronary Artery Ectasia

Resumo Fundamento A ectasia da artéria coronária (EAC) é definida como a dilatação difusa ou localizada do lúmen da artéria coronária com diâmetro de 1,5 a 2,0 vezes o diâmetro da artéria coronária normal adjacente. A relação proteína C-reativa/albumina (CAR, sigla em inglês) é um marcador inflamatório útil que tem sido documentado em doença arterial coronariana. Objetivo Analisar a associação entre a EAC e a CAR. Métodos Um protocolo caso-controle foi utilizado neste estudo. Foram incluídos 102 pacientesconsecutivos com EAC isolada sem estenose (56 homens e 46 mulheres; idade média de 60,4 ± 8,8 anos). O grupo controle era constituido pelo mesmo número de pacientes pareados por sexo e idade com artérias coronárias normais (55 homens e 47 mulheres; idade média de 61,2 ± 9,1 anos). Características clínicas, achados laboratoriais e histórico de uso de medicamentos foram registrados. Foram realizados teste t de Student, teste U de Mann-Whitney, teste do qui-quadrado, análise de regressão linear e logística. Foi considerado estatisticamente significativo p bilateral < 0,05. Resultados A CAR estava aumentada nos pacientes com EAC em comparação com os controles (32 e 16; p < 0,001). Além disso, foi verificado que a CAR era um preditor independente da EAC (razão de chances = 2,202; intervalo de confiança 95%, 1,184 - 5,365; p < 0,001). Conclusão No presente estudo, determinamos que os níveis da CAR estavam significativamente mais altos no grupo EAC que no grupo controle e a CAR estava significativamente correlacionada com a EAC.

Abstract Background Coronary artery ectasia (CAE) is defined as diffuse or localized dilatation of coronary artery lumen with a diameter of 1.5 to 2.0 times the adjacent normal coronary artery. The C-reactive protein to albumin ratio (CAR) is a useful inflammatory marker, which has been documented in coronary artery disease. Objective To analyze the association of CAE and CAR. Methods A case-control protocol was used in this study. We included 102 consecutive patients with isolated CAE without stenosis (56 men and 46 women; mean age 60.4 ± 8.8 years). The control subjects consisted of an equal number of sex and age matched patients with normal coronary arteries (55 men and 47 women; mean age 61.2 ± 9.1 years). Clinical features, laboratory findings, and medication use history were recorded. Student's t test, Mann-Whitney U test, chi-square test, and linear and logistic regression analysis were performed. A 2-sided p < 0.05 was statistically considered significant. Results The CAR was increased in patients with CAE compared to the controls (32 and 16; p < 0.001). In addition, the CAR was found to be an independent predictor of CAE (OR = 2.202; 95% CI 1.184 - 5.365; p < 0.001). Conclusion In the present study, we determined that CAR levels were significantly higher in the CAE group than in the control group, and the CAR was significantly correlated with CAE.

Giant right coronary artery aneurysm. case report

Introduction: Coronary aneurysms are rare and are linked to drug abuse; symptomatology depends on the coronary anatomy. This is a case of acute coronary syndrome associated with a giant right coronary aneurysm. Case description: A 40-year-old male, with history of heroin and crack use since age 20, attended consultation due to dyspnea, stable angina and diaphoresis. An electrocardiogram showed ST segment overlay on the underside and troponin problems. A coronary catheterization was performed, which revealed apparent inconclusive aorta-to-right atrium fistula. Based on the findings, angiotomography and magnetic resonance imaging were performed, finding a giant right coronary aneurysm. The aneurysm was resected using extracorporeal circuit, femoral cannulation, moderate hypothermia, aortic cross-clamping and cardioplegia, and the right coronary artery was revascularized with the left internal saphenous vein. The patient had a satisfactory postoperative period and was discharged after 7 days. Conclusion: There is an important association between drug use and the development of coronary aneurysms. Aneurysm size makes diagnosis difficult, so complementary studies are necessary to establish a differential diagnosis. An appropriate surgical approach allows for a complete resection of the aneurysm and optimal coronary revascularization.

Introducción. La presentación de aneurismas coronarios es rara, sin embargo se asocian al abuso de drogas; su sintomatología depende de la anatomía coronaria. Se presenta el caso de un síndrome coronario agudo asociado a un aneurisma gigante de la arteria coronaria derecha. Presentación del caso. Paciente masculino de 40 años con antecedente de consumo de heroína y crack desde los 20 años, quien consultó por disnea, angina estable y diaforesis. El electrocardiograma evidenció supradesnivel del segmento ST en cara inferior y elevación de troponinas, por lo que se realizó cateterismo coronario que reveló aparente fístula aorto-atrial derecha no concluyente. Dados los hallazgos, se decidió realizar angiotomografía y resonancia magnética que mostraron aneurisma gigante de arteria coronaria derecha. Se realizó resección de aneurisma con circulación extracorpórea, canulación femoral, hipotermia moderada, pinzamiento aórtico y cardioplejia, y se revascularizó la arteria coronaria derecha con vena safena interna izquierda. El paciente tuvo posoperatorio satisfactorio y se le dio de alta a los 7 días. Conclusiones. El tamaño del aneurisma puede dificultar su diagnóstico, por lo que estudios complementarios son útiles para establecer un diagnóstico diferencial. El abordaje quirúrgico adecuado permite realizar una resección completa del aneurisma y una revascularización coronaria óptima.

Angiographic characteristics and cardiovascular risk factors of coronary artery aneurysm and coronary artery ectasia / 中国介入影像与治疗学

Objective: To observe the differences of angiographic characteristics and cardiovascular risk factors of coronary artery aneurysm (CAA) and coronary artery ectasia (CAE). Methods Coronary angiographic data of 16 778 subjects were retrospectively analyzed. Results Coronary arteries dilatations were found in 211 patients, including 132 CAA (CAA group) and 79 CAE (CAE group). The morbidity of CAA, the concurrent morbidity of coronary heart disease (CHD) combined with CAA and Gensini score of CAA were all higher than that of CAE (all P<0.05). The average diameter of coronary arteries in patients with CAA was smaller than that in CAE patients (P<0.05), and thrombolysis in myocardial infarction (TIMI) was lower in CAA than CAE for all coronary arteries (all P<0.05). Dyslipidemia, smoking and family history of CHD were independent risk factors for CAA (all P<0.05). Conclusion: Significant differences of angiographic characteristics and cardiovascular risk factors exist between CAA and CAE.
