BACKGROUND AND OBJECTIVES: With the increasing survival of preterm infants, pulmonary hypertension (PH) related to bronchopulmonary dysplasia (BPD) has become an important complication. The aim of this study was to investigate the characteristics and outcome of PH in preterm infants with BPD and to identify the risk factors for PH. SUBJECTS AND METHODS: We reviewed the records of 116 preterm infants with BPD cared for at a single tertiary center between 2004 and 2008. RESULTS: Twenty-nine (25%)

INTRODUCTION: Echocardiographic studies have shown that some patients with Wolff-Parkinson-White (WPW) syndrome have myocardial dyskinesia in the segments precociously activated by an accessory pathway (AP). The aim of the present study was to determine the extent to which the AP contributes to global left ventricular (LV) dysfunction. METHODS: Electrophysiological and echocardiographic data from 62 children with WPW (age at diagnosis = 5.9 +/- 4.2 years) were retrospectively analyzed. RESULTS:

Liver cirrhosis and hepatocellular carcinoma (HCC) are serious late complications that can occur after the Fontan procedure. This study aimed to investigate the cumulative incidence of cirrhosis and HCC and to identify specific features distinguishing HCC from benign arterial-phase hyperenhancing (APHE) nodules that developed after the Fontan operation. We retrospectively enrolled 313 post-Fontan patients who had been followed for more than 5 years and had undergone ultrasound or computed tomogr

BACKGROUND: The safety and effectiveness of radiofrequency catheter ablation (RFCA) for supraventricular tachycardia (SVT) in young children was investigated. METHODS: Ninety-five children who underwent RFCA procedures were stratified according to age (group 1, 0-4 years, n = 24; group 2, 5-9 years, n = 71) and were evaluated retrospectively. RESULTS: Among the 95 patients, atrioventricular reentrant tachycardia was 78.9%, atrioventricular nodal reentrant tachycardia was 10.5%, and ectopic atria

Because cardiac dysfunction did not resolve after RT in pediatric population, regular evaluation for cardiovascular function after RT is required. Early RT may also be beneficial to global LV performance after RT.

OBJECTIVE: Changes in the epidemiology, clinical manifestations, and outcomes of infective endocarditis (IE) have been reported in recent years. This study was performed to analyze changing trends in the etiology of IE in children in South Korea. STUDY DESIGN: A retrospective study of children with IE was conducted from 2 hospitals in Korea from 2004 to 2019. IE was defined according to the Modified Duke criteria. We analyzed the etiology and clinical outcome of 96 cases and compared the etiolog

BACKGROUND: Patients with repaired congenital heart disease (CHD) can have both depolarization and repolarization abnormalities. A coexisting long QT syndrome (LQTS) may cause electrical instability in these patients; however, diagnosing LQTS is difficult owing to intraventricular conduction delay or paced rhythm after the operation. We report on six patients diagnosed with LQTS after CHD repair. METHODS: We investigated two male and four female patients. Clinical data, electrocardiographic find
