Transcatheter closure of atrial septal defects has become a popular procedure. The availability of a preprocedural imaging study is crucial for a safe and successful closure. Both the anatomy and morphology of the defect should be precisely evaluated before the procedure. Three-dimensional (3D) echocardiography and cardiac computed tomography are helpful for understanding the morphology of a defect, which is important because different defect morphologies could variously impact the results. During the procedure, real-time 3D echocardiography can be used to guide an accurate closure. The safety and efficiency of transcatheter closures of atrial septal defects could be improved through the use of detailed imaging studies.

With the marked decrease in operative mortality in simple heart diseases there have been several reports on the minimally invasive and cosmetic techniques including submammary incision right parasternal approach right anterolateral thoracotomy partial sternotomy and subxiphoid approach. We report here subxiphoid approach without sternotomy for the repair of atrial septal defect as the procedure that has less invasive technique and more cosmetic effect.

Thirteen year old boy who had been stabbed in his left chest by the knife was transferred to our department from a general hospital, because of the massive bleeding from the intercostal tube drainage. Chest X-ray showed homogeneous density in the left lung field. He was confused and his vital signs were unstable. He was moved into a operating room as soon as possible. After resuscitation, his lacerated left ventricle wound was sutured through median sternotomy. The interventricular shunt was detected with intraoperative transesophageal echocardiography. The traumatic ventricular septal defect was closed via left ventricle using Dacron patch. His postoperative course was uneventful, and he was discharged with small residual shunt.

Atrial septal defect is one of the most frequently encountered congenital heart disease. Up to December 31, 1976, 1682 cardiac patients received cardiac catheterization in the cardiac department of Yonsei university medical college. Out of the 1682 cardiac patients 723 cases had congenital heart disease and only 116 cases had congetial atrial septal defect. This amounted to 16.04% of all those with congenital heart disease. 58 cases of congenital atrial septal defect operated in the chest surgery department were presented. Of these 58 cases of atrial septal defect, 27 cases were male and 31 cases were female. Their ages ranged from 5 years to 54 years. The systolic pressure of the main pulmonary artery of 40 out of the 58 cases of atrial septal defect was below 40% of that of the systemic blood pressure: in 6 cases, the range of the systolic pressure of the main pulmonary artery was 50-90mmHg; in 12 cases, the range of the systolic pressure of the main pulmonary artery was 40-50mmHg. Average age of these was 30. 1 years. This study tends to show that Korean patients with atrial septal defect even though younger have a slight higher systolic pressure of the main pulmonary artery than Western patients have. The pulmonary blood is 1.5-2.5 times of systemic blood flow in 52 cases out of 58 cases of atrial septal defect.In only one of the 58 cases of atrial septal defect, the Rp was found to be as high as 45% of Rs. All other cases were below this level.51 cases had ostium secundum defect, 4 out of these cases had ostium secundum defect combined with mitral incompetence and 6 out of them had double ostium secundum defect. The remaining 7 cases had ostium primum defect. Their atrial defects were repaired under direct vision utilizing extracorporeal circulation, by hemodilution technic combined with moderate hypothermia. 44 cases [2nd atrial septal defect] were repaired by direct sutures while 14 cases, including the 7 cases ostium primum defects needed patches [1 pericardium and 13 teflon patch]. In 4 cases there were single defects while showed two defects. However the associated septal defect was so small that it could be closed by direct sutures. The size of the defect ranged between 6.0cm2and 10.0cm2 in 19 cases[33.7%]: the smallest being 0. 5cm2 and the largest 24cm2. The surgical mortality was 2 cases [3.4%]. These one case with ostium primum defect, could not be resuscitated on operation table. The cause of death in this case was myocardial failure and MI. The other, a case of ostium primum defect had a second operation on the first operative day due to massive bleeding from LV vent-line insertion site.The patient died on 26th post-operative day due to sepsis.

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.

Atrial septal defect (ASD) is one of the most common congenital heart defects in adults. Surgical repair is the most common treatment approach, but device closure has recently become widely performed in accordance with the trend toward less invasive surgical approaches. Although surgery is recommended when ASD is accompanied by atrial fibrillation, this study reports a case in which a complete cure was achieved by closure of a device and totally thoracoscopic ablation.

A 6-month-old male Ragdoll cat presented with exercise intolerance. On physical examination, there was a grade 2/6 systolic murmur at the right apex. Diagnostic tests, including SpO₂ measurement, blood tests, radiography, echocardiography, contrast echocardiography, and electrocardiography, were performed. Severe right atrial dilation, tricuspid valve leaflets and orifice displacement, right ventricular atrialization, septal leaflet adherence, anterior leaflet tethering, and right atrioventricular junction dilation were noted on echocardiography, alongside a right-to-left atrial septal defect. Cor triatriatum dexter and left ventricular aneurysm were observed. We diagnosed this case as having Ebstein anomaly with rare congenital heart deformities; which is rare in cats.

The report is concerned to our experience of 12 cases of open heart surgery under the extracorporeal circulation at the Department of Thoracic and Cardiovascular Surgery, Chosun University Hospital during the period between Nov, 1979 and April, 1983. 1. There were 4 cases of congenital anomaly and 8 cases of acquired heart disease. 2. There were 6 male and 6 female patients with a mean age of 20 years. [range 9 to 33 years]. 3. The cases induced 2 ventricular septal defect, 2 atrial septal defects and 8 acquired valvular heart diseases. 4. The surgical managements were 2 primary repair for atrial septal defect and 2 patch closure for ventricular septal defect, 1 triple valve replacement [AVR MVR TVR], 1 aortic valve replacement, 4 double valve replacement [AVR MVR] and 2 open mitral commissurotomy for pure mitral stenosis. 5. The average cardiopulmonary bypass time was 61.5 minutes for congenital heart disease and 201.4 minutes for acquired valvular heart disease and the average aortic cross clamping time was 36.75 minutes for the former and 165.6 minutes for the latter. 6. Postoperatively, there were 1 Alopecia, 1 Electric burn and 1 wound infection as complication. 7. Overall operative mortality was 8.3%. 7. All patients received valve replacement were recommended anticoagulation with persantin.

Postinfarction ventricular septal defect often induces cardiogenic shock and requires operative treatment early after myocardial infarction. Although the operative mortality of this disease has decreased during the past 3 decades, it is still relatively high. In this case, to prevent global myocardial ischemia, we used the technique of repair of postinfarction ventricular septal defect on a beating heart. This approach does not requir aortic cross-clamping and provides superior myocardial protection.

The noninvasive nature of the radionuclide angiocardiography provided a useful approach for the evaluation of left-to-right cardiac shunts (LRCS). While the qualitative information can be obtained by inspection of serial radionuclide angiocardiograms, the quantitative information of radionuclide angiocardiography can be obtained by the analysis-of time-activity curves using advanced computer system. The count ratios method and pulmonary-to-systemic flow ratio (QP/QS) by gamma variate fit method were used to evaluate the accuracy of detection and localization of LRCS. One hundred and ten time-activity curves were analyzed. There were 46 LRCS (atrial septal defects 11, ventricular septal defects 22, patent ductus arteriosus 13) and 64 normal subjects. By computer analysis of time-activity curves of the right atrium, ventricle and the lungs separately, the count ratios modified by adding the mean cardiac transit time were calculated in each anatomic site. In normal subjects the mean count ratios in the right atrium, ventricle and lungs were 0.24 on average. In atrial septal defects, the count ratios were high in the right atrium, ventricle and lungs, whereas in ventricular septal defects the count ratios were higher only in the right ventricle and lungs. Patent ductus arteriosus showed normal count ratios in the heart but high count ratios were obtained in the lungs. Thus, this count ratios method could be separated normal from those with intra cardiac or extracardiac shunts, and moreover, with this method the localization of the shunt level was possible in LRCS. Another method that could differentiate the intracardiac shunts from extracardiac shunts was measuring QP/QS in the left and right lungs. In patent ductus arteriosus, the left lung QP/QS was higher than those of the right lung, whereas in atrial septal defects and ventricular septal defects QP/QS ratios were equal in both lungs. From this study, it was found that by measuring QP/QS separately in the lungs, intracardiac shunt could be differenciated from extracardiac shunts.
