To compare clinical outcomes between age groups, infants aged 6–12 months...
Case Report
A rare type of single coronary artery with right coronary artery originating from the left circumflex artery in a child

Clin Exp Pediatr. 2015;58(1):37-40.   Published online January 31, 2015

The presence of a single coronary artery is a rare congenital anomaly; such patients often present with severe myocardial ischemia. We experienced the case of a 13-year-old girl with the right coronary artery originating from the left circumflex artery. She visited our Emergency Department owing to severe chest pain; her cardiac enzyme levels were elevated, but her initial electrocardiogram (ECG)...

A pediatric case of Brugada syndrome diagnosed by fever-provoked ventricular tachycardia

Clin Exp Pediatr. 2013;56(4):176-181.   Published online April 22, 2013
Purpose

Apical muscular ventricular septal defects (MVSDs), especially in small infants, can be difficult to manage using surgical and percutaneous closure. An intraoperative perventricular procedure is a good option for closing apical MVSDs in small children with or without associated cardiac anomalies. We evaluated the results of hybrid perventricular closure of apical MVSDs performed using an Amplatzer duct occluder (ADO).

Methods

We retrospectively...

Practical stepwise approach to rhythm disturbances in congenital heart diseases
June Huh
Clin Exp Pediatr. 2010;53(6):680-687.   Published online June 23, 2010

Patients with congenital heart diseases (CHD) are confronted with early- and late-onset complications, such as conduction disorders, arrhythmias, myocardial dysfunction, altered coronary flow, and ischemia, throughout their lifetime despite successful hemodynamic and/or anatomical correction. Rhythm disturbance is a well-known and increasingly frequent cause of morbidity and mortality in patients with CHD. Predisposing factors to rhythm disturbances include underlying cardiac defects,...

Ju Wan Kim, June Huh, Won Il Park, Kyung Ja Lee, Hong Jin Lee
Clin Exp Pediatr. 2001;44(1):94-98.   Published online January 15, 2001
Maple syrup urine disease is an autosomal recessive disease caused by a deficiency of the branched-chain α-ketoacid dehydrogenase complex. The disease is often suspected because of the peculiar odor of maple syrup in urine. Maple syrup urine disease is usually confirmed by amino acid analysis and urine organic acid analysis showing marked elevations of leucine, isoleucine, valine, and respective ketoacids in...
