  • Partial anomalous pulmonary venous connection is frequently found in any ASD(atrial septal defect) patients. These patients are usually symptomatic, therefore, easily diagnosed as just simple ASD. We experienced a case of a 37-year-old female patient with ASD in which the left upper pulmonary vein was connected to SVC by the left inominate vein. The patient was diagnosed as simple ASD previously. During cardiac catheterization, we found a meaningful oxygen saturation step up between the SVC and its upper portion. Angiogram confirmed PAPVC. The surgical correction of anastomosis of PAPVC with left atrial appendage and direct closure of ASD were done. The patient was discharged 15 days later.

  • The aim of the present experiments was to investigate the effect of Yukmijihwangtang water extracts on the plasma renin activity and plasma levels of atrial natriuretic peptide and aldosterone in rats. The results of this study were as follows: 1. Plasma renin activity decreased significantly after the administration of Yukmijihwangtang water extracts 1.5 ml/kg. 2. Plasma levels of atrial natriuretic peptide (ANP) decreased significantly after the administration of Yukmijihwangtang water extracts. 3. Plasma levels of aldosterone increased significantly after the administration of Yukmijihwangtang water extract.

  • Atrial natriuretic peptide(ANP)의 유리기전에 대한 특성을 알아보고자, 흰쥐의 적출심장 관류모형을 사용하여 연구한 바 다음과 같은 결과를 얻었다. 1. 심방을 확장시켰을 때 ANP의 유리는 촉진되었다. 그러나 과용량을 부하하면 확장기간보다 회복기간에 ANP의 유리가 현저하게 증가하였다. 2. Epinephrine과 phenylephrine을 주입하면 ANP의 유리 량이 증가했으나, isoproterenol을 주입하면 심박수와 우심방 내압이 현저하게 증가했는데도 ANP의 유리량은 오히려 감소하였다 3. 미주신경을 자극하면 심박수의 현저한 감소에도 불구하고 ANP의 유리량은 증가하였다. 이상과 같은 결과에서 볼 때 결론적으로, 심방의 용량부하에 의해 심방근의 신장수용체가 자극을 받아 ANP의 유리가 촉진되는 것은 분명하고, 심방근이 확장할 때 보다는 확장 후 다시 원래의 길이로 환원될 때 ANP가 유리될 것으로 사료된다. 그리고 ANP의 유리에 대한 adrenergic조절은 o-receptor가 관련되어 있으며 심박수와 심방내압이 ANP의 유리를 변화시키는 데는 반드시 필수적인 인자가 아닌 것으로 여겨진다. 또한 특히 미주신경의 자극으로도 ANP의 유리가 조절될 수 있다는 것이 본 연구를 통해 새로이 발견되었다.

  • A 6-month-old mature intact female Siamese cat presented with exertional dyspnea. Diagnostic studies revealed pleural effusion, grade 4/6 left basal systolic murmur, deep S-wave in electrocardiograph leads I, II, and III, cardiomegaly with pleural effusion on radiography, pulmonic systolic (~5.8 m/sec) and tricuspid (3.6 m/sec) regurgitant jets, atrial septal defect, and a hypoplastic right outflow tract. Based on these results, the case was diagnosed as pulmonic stenosis with atrial septal defect. To the best of our knowledge, this is the first case report describing pulmonic stenosis with atrial septal defect in a cat in Korea.

  • The aim of this experiments was to investigate the effect of Lycii Fructus water extracts on the blood pressure, plasma renin activity and plasma levels of atrial natriuretic peptide in two-kidney one clip Goldblatt hypertensive rats. Systolic blood pressure was decreased significantly after administration of Lycii Fructus water extracts. Plasma levels of atrial natriuretic peptide was increased significantly after adminstration of Lycii Fructus water extracts. Plasma renin activity was not changed after adminstration of Lycii Fructus water extracts. Thease results suggested that the depressor response after adminstration of Lycii Fructus water extracts were related with the changes of the plasma levels of atrial natriuretic peptide.

  • This paper proposes a new method for the automatic detection of atrial fibrillation (AF), using Markov regime switching GARCH (1, 1) model. The proposed method is based on the observation that variability patterns of heart rate intervals during AF significantly differ from regular patterns. The proposed method captures the different patterns of heart rate intervals between two regimes : normal and AF states. We test the proposed method using Massachusetts Institute of Technology-Beth Israel Hospital (MIT-BIH) atrial fibrillation database, and demonstrate the effectiveness of the proposed method.

  • The combined anomaly of pulmonary stenosis with atrial or ventricular septal defects is usually associated with decreased pulmonary blood flow and right to left shunt, and result in generalized cyanosis. Non-cyanotic pulmonary stenosis patients have generally been considered to have isolated pulmonary stenosis with intact septa. We are going to report a case of pulmonary stenosis with septal defects who have no frank cyanosis at rest because of the predominant intracardiac shunt from left to right. Recently, we managed surgically a case of pulmonary valvular stenosis combined with secundum type atrial septal defect, type II ventricular septal defect, and patent ductus arteriosus. The clinical manifestations of this patient were exertional dyspnea, frequent upper respiratory infection, chest discomfortness and lethargy since late childhood and these had been progressively aggravated. Pulmonary valvular stenosis, atrial septal defect and ventricular septal defect were closed through simply right atriotomy and patent ductus arteriosus through pulmonary arteriotomy. Immediate postoperative course was uneventful and one year follow up is excellent.

  • An atrial septal defect (ASD) is a congenital hole in the atrial septum that allows flow between the two atria. Small ASDs are usually well-tolerated defects and do not result in significant clinical abnormalities. In large ASDs or in the presence of other cardiac defects, clinically significancy is increased. Atrial septal defects in 2 Dogs with cardiac and respiratory signs were diagnosed at seoul animal medical center. In ascultation, systolic murmur and the splitting of second heart sound were heard at pulmonary or tricuspid valve region. In radiograph, right-sided cardiomegaly, pulmonary artery dilation, increased pulmonary vasculature makings, and pleural effusion or pulmonary edema signs were observed. In echocardiography, the region, location and size of septal defect was identified. Also, the direction and degree of shunt was measured. These dogs were treated with medicine for cardiac failure. One dog is well-tolerated, the other dog died.

  • Recently, a new method of evaluating left atrial size called vertebral left atrial size (VLAS) was introduced in dogs. Total 155 dogs were examined at the Veterinary Medical Teaching Hospital of Chungnam National University. In this study, myxomatous mitral valve disease (MMVD) stage and VLAS showed a significant correlation in those dogs. Also, the relationship between C-reactive protein (CRP) and VLAS has yet to be examined. We found a strong positive correlation between VLAS and CRP-a significant increase in CRP was observed with increasing VLAS values. Thus, it would be beneficial to measure VLAS besides employing the current radiological and echocardiographic methods when evaluating heart size. Measuring VLAS could be an additional diagnostic tool for diagnosing MMVD in dogs.
