PURPOSE: This study was designed to analyze the results of echocardiographic findings in children with heart murmur detected at mass health screening in Kyeong-Nam province. METHODS: Between 1996 and 2001, children with heart murmur underwent the echocardiographic examination at Gyoeongsang National University Hospital. RESULTS: The number of children examined was 129 in 1996, 26 in 1997, 44 in 1998, 61 in 1999, 60 in 2000, and 49 in 2001. By the echocardiographic examination, innocent murmur was the most commonly diagnosed(31-65%) and ventricular septal defect(VSD) was the most common cardiac defect. Between 1996 and 1998, complex cyanotic heart diseases were more frequent. The number of patients undergoing surgical treatment was 9 in 1996, 10 in 1997, 7 in 1998, 5 in 1999, 2 in 2000, and 2 in 2001. CONCLUSION: By the echocardiographic examination, functional murmur was the most commonly diagnosed and VSD was the most common cardiac defect. Currently, heart defects detected tend to be more simple and the surgical treatment needed seems to decrease in number.

Prosthetic valve endocarditis(PVE) is not infrequent and one of the serious complications of cardiac valve replacement despite advances in antimicrobial therapy, diagnostic techniquens and surgical procedures. Although the incidence of PVE may be declining, the absolute number of cases of this infection is increasing. In patients with a prosthetic valve, fever, a regurgitant heart murmur, peripheral manifestations of infective endocarditis and postitive blood cultures, the diagnosis of PVE is evident. We have reviewed our experience with 13 patients with PVE from October 1976 through August 1983. During this period valve replacements were performed in 686 patients, with an infection rate of 1.9%. PVE currently accounts for approximately 14% of the total number of cases of infective endocarditis seen at Seoul national University Hospital. PVE occurred more often after multiple valve replacement than after replacement of single valve alone. Blood cultures were positive in 69% cases of PVE. Systemic emboli could be seen in 54% of patients with PVE and overall mortality was about 23%.

Total anomalous pulmonary venous return (TAPVR) is a rare and critical congenital vascular anomaly that requires an early operation. However, initial symptoms of TAPVR may be non-specific, and cardiovascular findings may be minimal. The heart may not be enlarged and there is often no cardiac murmur. Without cardiac murmur, these symptoms are similar to those of respiratory distress syndrome in newborns. Therefore, a high degree of suspicion and an early diagnosis of TAPVR are important. This condition generally occurs without a family history and has a low recurrence rate, but several familial cases, including siblings, have been reported worldwide. Additionally, several chromosomal or gene abnormalities associated with TAPVR have been reported. In the case presented here, two brothers with a 6-year age gap were diagnosed with TAPVR. Surgery was performed without cardiac or neurological complications. This is the first report on TAPVR in siblings in Korea.

A total of 33 patients with infective endocarditis were observed in the Guro and Hye Hwa Hospitals of Korea University Between September, 1981 and Feb, 1987. Among thses patients four patients presented with heart murmur and heart failure and had vegetation like findings observed on the two dimensional echocardiography. But these patients did not have any fever or leukocytosis in the peripheral blood and the repeated blood cultures were negative. They showed the immunologic phenomena of infective endocarditis such as microscopic hematuria in 4 patients, rheumatoid factor in 3 patients, false positive VDRL in one patient. The serum complement was decreased in 2 patients in whom it was checked. We report these 4 patients because we think these patients might be in the clinical stage in which the infecting organism is spontaneously cleared but the immunologic sequelae are remained.

PURPOSE: To know the natural course of the ostium secundum ASD including its rate of spontaneous closure. METHODS: We studied 259 cases who were diagnosed as ostium secundum ASD by 2D-echocardiography at Department of Pediatrics, Kyungpook National University Hospital between Jan. 1985 and Dec. 1994. According to the age at diagnosis, we divided them into two groups, group I (those diagnosed before 1 month of age: 59 cases) and group II (those diagnosed after 1 month of age: 200 cases) RESULTS: Mean age at first diagnosis was 2.6+/-4.6 years and mean defect size(diameter by 2D-echocardiography) was 9.9+/-8.0 mm. Cardiac murmur was the main reason to refer the patients to hospital, being in 50 cases(87%) in group I, 179 cases(90%) in group II. Defect sizes were significantly small in group I compared with group II (5.3+/-3.4 mm vs 11.1+/-6.9 mm, p<0.05). Symptoms corresponding to congestive heart failure were present in 16 cases of group I (27%)( isolated ASD: 8 cases, ASD accompanying with PDA: 5 cases, ASD accompanying with VSD: 2 cases, ASD accompanying both PDA and VSD : 1 case) and in 27 cases of group II(13.5%) (isolated ASD: 17 cases, ASD accompanying with VSD: 4 cases, ASD accompanying with PDA: 4 cases, ASD accompanying both PDA and VSD: 2 cases). Of total 139 cases, spontaneous closure of ostium secundum ASD was documented in 14 cases(10.1%) by follow up 2D-echocardiography. The rate of spontaneous closure was significantly high in group I compared with group II (6 cases: 37.5% vs 8 cases: 6.5%, p<0.05) Comparing with those cases without closure, there were no significant differences in defect size in group I but significant differences in group II(p<0.05), being 5.63 2.62 mm in cases with spontaneous closure and 12.82 7.09 mm in those cases without closure. Of the 9 cases with atrial septal septal aneurysm, 2D- echocardiographic follow ups were possible in 5 cases with spontaneous closure in 2 (40%). CONCLUSIONS: Spontaneous closure was documented in 10.1% of all the patients with ostium secundum ASD. Especially the closure rate was significantly high in those cases their diagnosis was made before 1 month of age and with atrial septal aneurysm.

We experienced a case of spondylothoracic dysplasia in a 1 day old male who has short neck with limitation of movement, asymmetric thorax, marked scoliosis and a systolic heart murmur. He was born with normal weight and full term. The history of his family and mother is not specific. On x-ray, multiple hemivertebrae in thorax, spina bifida and maldevelopmental thoacic cavity were detected. On echocardiogram, he had small ASD and PDA.

PURPOSE: In Rett syndrome patients, the incidence of sudden death is greater than that of the general population, and cardiac electrical instability including fatal cardiac arrhythmia is a main suspected cause. In this study, we are going to find out the possible cause of the higher risk of sudden death in Rett patients by the evaluation of heart rate variability, a marker of cardiac autonomic activity and corrected QT intervals. METHODS: Diagnosis of Rett syndrome was made by molecular genetic study of Rett syndrome (MECP2 gene) or clinical diagnostic criteria of Rett syndrome. Heart rate variability and corrected QT intervals were measured by 24 h-Holter study in 12 Rett patients, and in 30 age-matched healthy children with chief complaints of chest pain or suspected heart murmurs. The were compared with the normal age-matched control. RESULTS: Patients with total Rett syndrome, classic Rett syndrome, and Rett variants had significantly lower heart rate variability(especially rMSSD)(P<0.05) and longer corrected QT intervals than age-matched healthy children(P<0.05). Sympathovagal balance expressed by the ratio of high to low frequency(LF/HF ratio) also showed statistically significant differences between the three groups considered(P<0.05). CONCLUSION: A significant reduction of heart rate variability, a marker of autonomic disarray, suggests a possible explanation of cardiac dysfunction in sudden death associated with Rett syndrome.
