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

چکیده
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.

Junctional ectopic tachycardia evolving into complete heart block.
Transition from congenital junctional ectopic tachycardia to complete AV block was observed in an 8 month old girl, over a 36 hour period, during initial hospital admission. Two years later she had evidence of a rapidly increasing left ventricular end diastolic diameter, associated with lowest heart rates during sleep of < 30 beats/min. A transvenous permanent pacemaker was therefore implanted....

OBJECTIVES The purpose of our work was to define the complex electrophysiological characteristics seen in second- (2 degrees) and third-degree (3 degrees) atrioventricular block (AVB) and to longitudinally follow the development of atrial and ventricular heart rate and rhythm patterns with a goal of identifying heart rate and rhythm patterns associated with urgent delivery or neonatal pacing. ...

Left ventricular aneurysms (LVAs) can be congenital or acquired. They develop most frequently after myocardial infarction. Other causes include hypertrophic cardiomyopathy, arrythmogenic right ventricular cardiomyopathy, myocarditis, chest trauma, sarcoidosis or Chagas disease [1, 2]. LVAs without identifiable cause are considered as idiopathic. Most of LVAs are asymptomatic and are occasionall...
