Comparison of Efficacy of Transcatheter Closure of Atrial Septal Defect with Amplatzer Septal Occluder between Children and Adult

PURPOSE: This study sought to analyze the safety, efficacy, and follow-up results of percutaneous closure with Amplatzer septal occulder (ASO) for secundum atrial septal defect (ASD) in less than 10 years old by comparing to those of adult. METHODS: We divided 49 enrolled subjects to two groups as childhood group (25 patients, 10 years). We evaluated hemodynamic changes, including Qp/Qs, systolic right ventricular pressure, pulmonary artery pressure in pre- and post-treatment. The residual shunt rate and complications were investigated. Then, we compared the results between two groups. RESULTS: The success rate of two groups was not statistically different (100% vs 95.8%). The hemodynamic changes, including Qp/Qs, systolic right ventricular pressure, pulmonary artery pressure were statistically significant between pre- and post-treatment (all P0.2). The residual shunt rate and complications occurrence rate were not statistically significant between two groups. CONCLUSION: The cure rate and complications by percutaneous closure of ASD with ASO were not different between in children and in adult. This procedure was an effective treatment modality for ASD in children like in adult.

Platelet Status in Thrombocytosis Period of Kawasaki Disease

PURPOSE: The relationship between the number and size of platelet in the thrombocytosis period of Kawasaki disease (KD) was analyzed to investigate the risk of thrombosis in KD. METHODS: The number and size of the platelet in patients with KD (n=221) were serially evaluated and the relationship was analyzed. RESULTS: The value of mean platelet volume (MPV) was inversely correlated with the highest number of platelet with r(2)=0.0741, P < 0.001. CONCLUSIONS: Considering the size of the platelet, the vulnerability of thrombosis during the thrombocytosis period of KD might be low.

Anomalous systemic arterial supply to lung without sequestration in an infant who has congenital heart disease: a case report / 소아과

Systemic arterial supply from the aorta to the lung is a rare congenital anomaly within the spectrum of bronchopulmonary sequestration according to Pryce's terminology. We describe our experience of this anomaly in an infant with congenital cardiac disease confirmed by multidetector CT scan. We found a systemic arterial supply from the aorta to the right lower lobe of lung without right lower lobar pulmonary artery and bronchopulmonary sequestration. This combination of congenital anomaly is most rare form.
