Aortic valve insufficiency with ventricular septal defect is usually treatment by plication of prolased cusps. We have performed the aortic valvuloplasty by the Trusler`s method in 14 patients of ventricular septal defect associated with aortic insufficiency. The reoperations were performed in the 4 cases[29%] due to recurrent aortic insufficiency after aotic valvuloplasty. Two patients underwent aoritc valvular replacements for the tears of repaired aortic cusps after primary aortic valvuloplasty for aortic insufficiency. The other two patients had aortic valvuloplasties again. Death occured in one case of aortic valvular replacements. The cause of death was low cardiac output syndrome soon after aortic valvular replacement for recurrent aortic insufficiency .

We have experienced a patient, 16 year-old male, with ventricular septal defect with tricuspid recur- gitation due to blunt chest trauma. He suffered from congestive heart failure after the trauma. Echocardiogram and cardiac catheterization revealed left to right shunt at the ventricular level (muscu- far portion of interventricular septum) and tricuspid regurgitation. At the time of the operation, marked systolic thrill was palpable over the rlght ventricle near the apex and a chorda tendina was seen sharply ruptured just near the medial papillary muscle. We repaired the ventricular septal defect with a Dacron patch and chordal reconstruction with autologous pericardium. The postoperative course was uneventful and the patient was discharged in good condition.

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.

During one year[1987], 110 cases of open heart surgeries were performed in the department of Thoracic and Cardiovascular Surgery, Pusan Paik Hospital, Inje Medical College. And the results were summarized as follows. 1. Among the 110 cases, there were 77 cases of congenital heart diseases and 33 cases of acquired heart diseases. Age range of the congenital patients was 8 months to 30 years with the mean age of 8 years, and acquired patients was 16 to 56 years with the mean age was 32 years. 2. The heart lung machine used for cardiopulmonary bypass was Sarns 7000, 5-head roller pump, and the number and type of oxygenators were 50 of membrane type and 60 of bubble type. For all cases GIK[glucose-insulin-potassium] solution was used as cardioplegic solution for myocardial protection during operation. 3. Among the 77 congenital anomalies, there were 67 cases of acyanotic patients[ASD: 12, VSD: 50, PS: 1, AP window: 1, Gerbode defect: 1, ECD: 2] and 10 cases of cyanotic patients[TOF: 10], and to all of which the appropriate radical operations were applied. 4. Among the 33 acquired diseases, there were one case of left atrial myxoma, one of annuloaortic ectasia, 20 of mitral valve diseases[MS: 2, MSr: 8, MR: 2, MRs: 8], 9 of double valve diseases[MRs+AR: 1, MRs+ARs: 2, MRs+TR: 1, MSr+TR: 3, MSr+ASr: 1, MSr+ARs: 1], 2 of triple valve diseases[MSr+AR+TR: 1, MSr+ASr+TR: 1]. The left atrial myxoma was removed well with right atriotomy and atrial septal approach. And to the annuloaortic ectasia, Bentall operation was applied with good result. Mitral valve replacement[MVR] was applied to 20 cases of mitral valve diseases, double valve replacement[MVR+AVR] was applied to 6 cases of double valve diseases, MVR & tricuspid annuloplasty[TVA] was applied to 3 cases of mitral 5. The number of replaced valve were 39 in 31 cases. In MVR, 5 of mechanical valves[St. Jude Medical Valve] and 26 of tissue valves[Carpentier-Edward valve] were used. In AVR, 3 of mechanical valves and 5 of tissue valves were used. 6. Postoperative complications were occurred in 23 cases, and among them 21 cases were recovered with intensive cares, but 2 cases were expired[mortality: 1.8%].

This is one case report of surgically treated partial atrioventricular canal. The 22 year-old male patient had no definitive history of frequent respiratory infection and cyanosis in his early childhood. Since his age of 7 years, dyspnea was manifested on exertion. First appearance of congestive heart failure was at his age of 16 years old. The physical examination revealed that the neck veins were distended and heaving of precordium. A thrill was palpable on the left 3rd-4th intercostal space extending from the sternal border toward the apex and Grade IV/VI systolic ejection murmur was audible on it. Neither cyanosis nor clubbing was noted. Liver was palpable about 5 finger breadths. Chest X-ray revealed increased pulmonary vascularity and severe cardiomegaly (C-T ratio = 74%). EKG revealed LAD, clockwise rotation, LVH and trifascicular block. Echocardiogram showed paradoxical ventricular septal movement, narrowed left ventricular outflow tract and abnormal diastolic movement of the anterior leaflet of mitral valve. Right heart catheterization resulted in large left to right shunt (Qp : Qs = 5.7: 1), ASD and moderate pulfllonary hypertension. Finally, left ventriculogram revealed typical goose neck appearance of left ventrlcalar outflow tract. On Oct. 10, 1980, open heart surgery was performed. Operative findings were: 1. Large primum defect ($6{\times}5$ Cm in diameter) 2. Cleft on the anterior leaflet of mitral valve. 3. The upper portion of ventricular septum was descent but no interventricular communication. 4. Downward attachment of the atrioventricular valves on the ventricular muscular septum. 5. Medium sized secumdum defect ($2{\times}1$ Cm in diameter). The cleft was repaired with 4 interrupted sutures. The primum defect was closed with Teflon patch and the secundum defect was closed with direct suture closure. Postoperatively atrial flutter-fibrillation in EKG and Grade U/VI apical systolic murmur were found. The postoperative course was uneventful and discharged on 29th postoperative day in good general conditions.

Background: Minimally invasive cardiac surgery has emerged as an alternative to conventional open surgery. This report reviews our experience with atrial septal defect using the da VinciTM surgical robot system. Materials and Methods: This retrospective study included 50 consecutive patients who underwent atrial septal defect repair using the da VinciTM surgical robot system between October 2007 and May 2011. Among these, 13 patients (26%) were approached through a totally endoscopic approach and the others by mini-thoracotomy. Nineteen patients had concomitant procedures including tricuspid annuloplasty (n=10), mitral valvuloplasty (n=9), and maze procedure (n=4). The mean follow-up duration was $16.9{\pm}10.4$ months. Results: No remnant interatrial shunt was detected by intraoperative or postoperative echocardiography. The atrial septal defects were mainly repaired by Gore-Tex patch closure (80%). There was no operative mortality or serious surgical complications. The aortic cross clamping time and cardiopulmonary bypass time were $74.1{\pm}32.2$ and $157.6{\pm}49.7$ minutes, respectively. The postoperative hospital stay was $5.5{\pm}3.3$ days. Conclusion: The atrial septal defect repair with concomitant procedures like mitral valve repair or tricuspid valve repair using the da VinciTM system is a feasible method. In addition, in selected patients, complete port access can be helpful for better cosmetic results and less musculoskeletal injury.

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.

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.

An eight-year-old boy was referred to our hospital with cough and high fever. His past medical history included a small sized ventricular septal defect (VSD) at birth. Transthoracic echocardiography disclosed a 10 x 6 mm vegetation on tricuspid valve, a small VSD and the moderate tricuspid valve insufficiency were found. Blood cultures grew methicillin-resistant staphylococcus aureus. Despite proper antibiotic therapy, fever was not controlled and his course was complicated by pulmonary infarction. The patient simultaneously underwent pulmonary resection and open heart surgery. Through the median sternotomy we performed open thrombectomy and lobectomy (right lower lobe) at first, and then vegetectomy, tricuspid valve repair, and direct closure of VSD were done under cardiopulmonary bypass.

A hemangioma at a cardiac valve leaflet is a rare finding. There are only five reported cases in the medical literature and no prior case reported in Korea. A previously healthy 45-year-old woman presented with an acute episode of numbness in the left side of the face and hand. Although no definite abnormalities were found on the neurological examination and testing the echocardiography revealed an echogenic mass in the anterior mitral valve leaflet. The tumor was excised en bloc from the leaflet and the defect was repaired with an autologous pericardial patch. Pathology examination confirmed the mass to be a hemangioma of the valve leaflet. Here we report this case and review the medical literature.
