“…15,17 On the contrary, few neonatal case reports have described infants with neonatal enterovirus myocarditis with supraventricular arrhythmias that were not accompanied with serious left ventricular dysfunction. 9,14 There is only one report describing a case very similar to ours, of an infant with viral myocarditis who had A-V block and JET. 16 Interestingly, the infant in this report also had no accompanying left ventricular dysfunction.…”

“…5 Usual arrhythmias associated with enterovirusinduced myocarditis include sinus tachycardia, supraventricular tachycardia, arterial flutter, ventricular tachycardia, and complete A-V block (Table 1). 1,[6][7][8][9][10][11][12][13][14][15] JET associated with neonatal viral myocarditis has only been reported twice. 14,16 Although amiodarone is not an established therapy for neonates, we used amiodarone in accordance with a previous report.…”

Reversible Atrioventricular Block and Junctional Ectopic Tachycardia in Coxsackievirus B3-Induced Fetal–Neonatal Myocarditis without Left Ventricular Dysfunction

We present a case of fetal–neonatal acute myocarditis caused by coxsackievirus B3 infection in a term neonate. The condition manifested as high-grade atrioventricular (A-V) block prenatally. After delivery, various arrhythmias such as high-grade A-V block, ventricular tachycardia, and junctional ectopic tachycardia appeared, and we had difficulty managing these arrhythmias. This is the first report describing a case of acute myocarditis due to coxsackievirus infection presenting with fetal A-V block. This case is also unique in that it is extremely rare that various arrhythmias occur serially in one patient without left ventricular dysfunction.

Clinical Pearls in Pediatric Cardiology

In this section, the authors present four interesting clinical cases that presented with common symptoms, but required careful clinical examination and investigations to arrive at a correct diagnosis and institute appropriate management. The first case is a 3-month-old infant who presented with hypertonia, bulging anterior fontanelle and tachycardia. ECG revealed supraventricular tachycardia which was managed appropriately. The clinical suspicion of meningitis was not borne out by the CSF findings. The second is a pre-school girl who presented with recurrent, episodic wheezing that did not respond to standard asthma therapy. The authors discuss the management approach in such cases; careful examination of radiographs and clinical course led to the correct diagnosis of dilated cardiomyopathy. The next two cases are older children; one of them presented with massive bilateral pleural effusion; this was found to be caused by congestive cardiac failure. The last case is a 10-year-old child presenting with features of right sided heart failure without obvious cardiac abnormality on clinical examination. Advanced investigations confirmed a rare diagnosis of arrhythmogenic right ventricular dysplasia; retrospective ECG examination showed the characteristic findings of this condition.

“…In infants, arrhythmias may be also secondary to respiratory syncytial virus (RSV) infections, particularly when pericarditis or myocarditis is observed [22]. Generally, each infection of the heart might be associated with cardiac complications secondary to viremia and generate cardiac arrhythmias [23][24][25]. It is unknown which factor may trigger cardiac arrhythmias in older children after excluding obvious cardiac defects and other detectable pathologies.…”
