An atrial septal defect (ASD) is congenital heart disease with a communication between the atria, which allows blood to shoot from the atrium with pressure. A 3-month-old female Miniature Schunauzer was referred to the Veterinary Teaching Hospital of Konkuk University for the evaluation of systolic heart murmur. At presentation, the mucous membrane was cyanotic. On physical examination, an ejection-type systolic murmur was auscultated at the pulmonic area. In addition, thoracic radiography showed enlargement of main pulmonary artery and right atrial/ventricular enlargement. Echocardiography revealed dilated right atrium and atrial septal defect. However, mitral and tricuspid valve were still intact and well tolerating. The presence of an ASD was confirmed by identifying flow across the defect with color Doppler imaging. Doppler echocardiography provides a means of non-invasive documentation and quantification of ASD. Complete blood count and serum chemistry were not remarkable. Although large defect was confirmed between the two atrium, the patient did not show any obvious clinical signs of heart failure at this time.

Left ventricular-Right atrial canal is a rare congenital heart disease. The vast majority of the cases reported in the literature are clinically diagnosed as atrial septal defect or ventricular septal defect. The method of choice in establishing the diagnosis of left ventricular-right atrlal canal is selective left ventriculography. Recently we experienced one case of left ventricular-right atrial canal which was diagnosed as ventricular septal defect preoperatively. The type of defect was tricuspid perforation of infravalvular type, and repaired with direct suture. Postoperative course was uneventful and discharged without complication.

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.

We present a case of coronary artery fistula originating from the proximal left anterior descending artery draining into the main pulmonary artery, which was associated with atrial septal defect. The patient was a 56 year old male who was admitted for exertional dyspnea and abdominal distension. Echocardiogram and selective coronary arteriogram revealed a atrial septal defect and fistulous connection. The patient underwent surgery under the cardiopulmonary bypass with fibrillating heart. The pericardial patch closure of atrial septal defect and internal obliteration of the fistula termination site in the main pulmonary artery were performed. Postoperative hospital courses were uneventful without any specific complication and the patient was discharged without problem.

Repairs of atrial septal defect utilizing cardiopulmonary bypass were performed in 50 adults, ranging age from 16 to 53 years, since April 1986 up to October 1994. They occupied 38.8% of all adult congenital heart disease operated in the same period. Preoperatively, 16 patients were functional class II, 12 patients class III and 4 patients class IV[New York Heart Association Classification , respectively. Five patients combined with atrial fibrillation and the remainders revealed regular sinus rhythm. Cardiac catheterizations were performed in 43 out of 50 patients, and revealed a systolic pulmonary arterial pressure in excess of 51 mmHg in 4 patients but none had reversed shunt. 40 patients[80% were repaired with patch closure and remainings were repaired with direct closure. 49 patients were followed up for 2 months up to 102 months[average 55 months . A comparison of the preoperative and postoperative functional class demonstrated a mean decrease of one NYHA functional level[2.5$\pm$0.63 to 1.4$\pm$0.56 . There was no operative mortality. One patient died during the follow-up period and the death was unrelated to heart disease. Operative treatment is indicated for repair of atrial septal defect with left to right shunt in the adult patient and a considerable clinical improvement can be anticipitated with low mortality.

Recently, radionuclide angiocardiogram is one of the most common procedure for assessment of ventricular performance due to its distinctive advantages such as safety, accuracy, and ease of repeated studies. Also, measurement and comparison between pre and postoperative left ventricular ejection fraction [LVEF] are meaningful for assessing the severity of myocardial damage which occurred during open heart surgery and the status of myocardial recovery. We obtained pre and post operative LVEF using radionuclide angiocardiogram on 30 patients composed of atrial septal defect, ventricular septal defect, cyanotic congenital heart disease, and valvular heart disease who undergone the open heart surgery from March to august 1984. The study revealed that ventricular septal defect and mitral valvular heart disease showed 8.1% and 6.2% decreases of postoperative LVEF, respectively. But, there are little increases of postoperative LVEF in the atrial septal defect and cyanotic congenital heart disease. In ventricular septal defect, each group of Qp/Qs over 2.0 and systolic pulmonary artery pressure over 50mmHg showed significant 17% and 14.7% decreases of postoperative LVEF, respectively. Considering the duration of the aortic cross clamping times and closing methods of VSD, each group of duration over 30 min. and of patch closure showed 13.9% and 14.2% decreases of LVEF between pre and postoperative status respectively which was significant finding statistically.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.

Cor triatriatum is a rare congenital malformation of the heart, in which a septum stretches in a transverse or oblique plane through the left atrium, thus separating it into two compartments. The upper one connects with the pulmonary veins, and the lower one connects with the left ventricle. Due to the rarity of, and great difficulty in-diagnosing, cor trlatrlatum, data On the surgery of this disease are of necessity very limited and so accurate pre-operative diagnosis was very difficult to make. `We experienced a case of the cyanotic congenital heart disease which was diagnosed as a large atrlal septal defect with streaming venous blood from inferior vena cava to left atrium through atrial septal defect in August, 1982. We found that there were transverse septum in the left atrium through atrlal septal defect, the pulmonary venous drainage were located in the upper chamber of the left atrium, and the lower chamber was connected with the left atrial appendage, mitral valve and `left ventricle. But our case had not any opening in this transverse septum and the right atrium was connected with the upper chamber of the left atrium through the upper part of the atrlal septal defect, and was communicated with the lower chamber of the left atrium through the lower part of the atrlal septal defect. We excised the transverse septum and repair this atrial septal defect with Woven Dacron patch accompanying with the drainage of coronary sinus to right atrium. The post-operative course was not eventful and he was discharged with good result on the post-operative 8th day, and has been in good .condition up to now for longer than 10 months.

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.

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.
