INTRODUCTION AND OBJECTIVES: The resting 12-lead electrocardiogram (ECG) has been used in the evaluation of young asymptomatic individuals to detect pre-existing heart disease, but systematic ECG use is controversial and there are no data on this population in our environment. We aimed to determine the prevalence and spectrum of electrocardiographic findings in a population of secondary school students. METHODS: We conducted an observational, cross-sectional study of resting ECG findings in all 13 to 14-year-old secondary school students in a region of the province of Gerona between 2009 and 2017. ECG findings were classified into 3 groups according to the modified criteria of Corrado et al.: normal ECG findings, ECG findings suggestive of adaptive changes, and pathologic findings. Students with pathologic ECG findings were referred to a tertiary hospital, and complementary tests were performed according to a pre-established protocol. RESULTS: A total of 1911 ECGs were obtained, with a participation rate of 79% of all high school students. In all, 1321 students (69%) had a normal ECG, 554 (29%) showed ECG findings suggestive of adaptive changes, and 36 (2%) had pathologic ECG findings. Among the group with pathologic findings, 5 (14%) had cardiovascular disease. The prevalence of heart disease in this group of asymptomatic secondary school students was 0.3%. CONCLUSIONS: One third of the students had ECG findings that were mostly suggestive of physiological adaptation. One seventh of the students with pathologic ECG findings had pre-existing heart disease, although the overall prevalence of pre-existing heart disease was low.

"Persistence of the fifth aortic arch" is a rare congenital abnormal vessel arising from the distal ascending aorta connecting with the systemic or pulmonary circulation. We report a case of a type A interruption of the aortic arch and a coarctation of the fifth aortic arch, which connected the ascending with the descending aorta. No cardiac surgery was required because a covered stent was successfully implanted in the fifth aortic arch when the patient was 4 years old. A chromosome 9 q arm duplication of uncertain significance was also found, an anomaly never described before in this clinical context.

Chest pain is a typical symptom of acute myocarditis in adolescents. It may be indistinguishable from myocardial ischemia so it is called "infarct-like pattern." Cardiovascular magnetic resonance has an important role as a non-invasive diagnostic tool. The aim of our study is to provide a description of an acute myocarditis series with infarct-like pattern and to evaluate the cardiovascular magnetic resonance role in a pediatric population. We included all pediatric patients (0-16 years) admitted to our hospital (May 2007-May 2016) with clinical diagnosis of acute myocarditis and infarct-like presentation (chest pain, EKG alterations, and released cardiac biomarkers). Diagnosis was confirmed with cardiovascular magnetic resonance using Lake Louise criteria. Seven patients (five males, two females) with a median age of 14 years (12.5-15.2) were included. All patients showed ST-segment changes and released cardiac biomarkers. Three patients had left ventricular hypertrophy and two presented mild systolic left ventricular dysfunction. All patients had at least two positive Lake Louise criteria. Late gadolinium enhancement was positive in all of them. With a median follow-up of 23 months (8-47), all of them are alive, with no cardiac symptoms and normal ventricular function. Infarct-like pattern is a typical presentation of acute myocarditis in adolescents. CMR should be performed in this population and may be considered as a first-line diagnostic tool. Its high sensitivity in infarct-like acute myocarditis may allow us to avoid endomyocardial biopsy. Unlike what was described in adults, late gadolinium enhancement does not imply worse outcome in our series.

Chiari network is an embryonic remnant of valves of the sinus venosus, which can be observed in several locations in the right atrium. Although it is usually considered a normal anatomic variant, when associated with certain clinical conditions, the Chiari network may become a confusing finding, and a careful differential diagnosis is required. It should be differentiated from a tricuspid valve disruption, vegetation, thrombus, or tumoral mass. In this case report, we describe a singular case of endocarditis over a Chiari network in a seven-year-old boy that was successfully managed in a conservative fashion.
