Background: Secundum atrial septal defect (ASD) is a common congenital heart defect in adults. Patients with ASDs at high risk of cardiovascular complications undergo either surgical repair or percutaneous device closure. Case Report: We report the case of an 85-year-old male with unusual recurrent cerebral infarctions. The patient has undergone repair of secundum ASD 12 years ago. Evaluation by transesophageal echocardiography revealed a mobile mass at the patch repair site in the left atrium. The mass was surgically removed due to recurrent stroke during the anticoagulation. Conclusion: This case emphasizes the importance of regular cardiac checkup and the need to consider cardioembolic source as being part of the etiology of stroke recurrence, even if the event occurs many years after intracardiac shunt closures.

Clinical analysis was performed of 89 secundum type atrial septal defect patients operated on during the period from July, 15th, 1981 to March, 1987 in the Thoracic and Cardiovascular Surgery Department of Pusan National University Hospital. Secundum type ASD was 2`I.0% among all of congenital heart diseases operated in the same period. The age distribution of patients ranged from 3 to 41 years and sex ratio, male to female was 1.23 to 1.0. Common symptoms were exertional dyspnea 64.0%, frequent upper respiratory infection 43.8%, cyanosis 10.1% and fatigue 7.9%. The mean value of cardiac catheterization data of the group of ASD combined with another cardiovascular anomalies was compared with that of only ASD group. The amount of shunt showed not statistically significant difference between two groups [P>0.05] but pulmonary arterial pressure and pulmonary vascular resistance of combined group was significantly higher than that of only ASD group [P<0.02, P<0.01]. The difference of mean hemodynamic data between the age group below 20 years and above 21 years was not statistically significant [P>0.05]. All cases were operated under cardiopulmonary bypass. Among these 51 were closed directly and 38 were applied Dacron patch. Two most common associated cardiac anomalies were pulmonary stenosis [8 cases, 9.0%] and VSD [8 cases, 9.0%]. The most frequent postoperative complication was wound infection, One patient died of low cardiac output on 10th postoperative day and the overall operative mortality was 1.1%

The study consisted of all patients undergoing surgical repair of isolated secundum type atrial septal defect in patients ages 35 years or older for the period from October 1986 to October 1991. ASD was closed with direct suture in all patients. Response to surgery was excellent. Two patients who had atrial fibrillation was taken low-dose warfarin therapy to prevent stroke. All patients survived operation, and improved by at least one New York Heart Association functional classification. An old age was not a contraindication to surgery.

Endocardial cushion defects is a rare congenital heart disease. We experienced two complete endocardial cushion defects[ECD] and three partial ones, which were successfully repaired between 1986 and 1987. In a patient of complete ECD, associated with secundum ASD, Pulmonary stenosis and Down`s syndrome, the atrial and ventricular septal defects were closed separately with bovine pericardium and Dacron patches respectively, and then pulmonary stenosis was relieved by transannular patch widening in addition to valvotomy and infundibulectomy. In another patient with complete ECD, small interventricular communication was closed with simple suture with pledget and primum ASD was closed with pericardial patch. In first patient of partial ECD, primum atrial septal defect was closed with pericardial patch. In second patient of partial ECD, associated with secundum ASD, direct closure of secundum ASD and patch closure of primum ASD were performed. In third patient of partial ECD, associated with patent foramen ovale[PFO], primum ASD was closed with bovine pericardial patch and PFO was closed directly. In all patient except third patient of partial ECD, mitral clefts were closed with three or four 5-0 prolene interrupted sutures. Transient A-V dissociation developed postoperatively in two patients and transient nodal rhythm developed postoperatively in other two patients. Heart failure in complete ECD with Down`s syndrome was overcome with medical treatment.

Thirteen patients underwent repair of atrioventricular septal defect [AVSD] from January 1980 to July 1989 at Kyungpook National University Hospital. Two patients had complete AVSD [Rastelli type A] and eleven patients had partial AVSD [ostium primum atrial septal defect and cleft of anterior mitral leaflet]. In all the patients of partial AVSD, atrial septal defect was closed with Dacron patch and the mitral cleft was approximated with interrupted simple sutures. In one patient of complete AVSD, one patch technique was used to close the atrial and ventricular septal defect, and in the other patient of complete AVSD, two patch technique was used. In six patients, there were associated anomalies; four had isolated ostium secundum ASD, two had patent foramen ovale. Postoperative complete A-V block was noted in a patient of partial AVSD, but it was returned to 1st degree A-V block 30 months later and in another case of partial AVSD, severe congestive heart failure [NYHA functional class IV] due to residual mitral insufficiency was developed postoperatively, but this patient was recovered to the state of functional class I after receiving mitral valve replacement. There was one hospital death [8 %] resulting from low cardiac output.

Point mutations in the human cardiac homeobox gene NKX2.5 are associated with familial atrial septal defect (ASD), atrioventricular (AV) conduction disturbance, as well as sudden cardiac death. To date, more than 60 NKX2.5 mutations have been documented, but there are no reports in Korea. We are reporting the first Korean family with ASD and AV block associated with a novel mutation in the NKX2.5 coding region. A 9-year-old boy presented with a slow and irregular pulse, and was diagnosed with secundum ASD and first degree AV block. The boy's father, who had a history of ASD correction surgery, presented with second degree AV block and atrial fibrillation. The boy's brother was also found to have secundum ASD and first degree AV block. There were two sudden deaths in the family. Genetic testing revealed a novel mutation of NKX2.5 in all affected members of the family.

Cor triatriatum is a variant of abnormal connection between the pulmonary vein and true left atrium, which is separated from accessory left atrium receiving pulmonary venous blood flow by fibromuscular diaphragm. Usually it is diagnosed after operation because difficulty in visualization of the diaphragm by conventional diagnostic tools. We experienced a rare entity of congenital heart disease diagnosed as car triatriatum with atrial septal defect and partial anomalous pulmonary venous return after completing operation, which was diagnosed as ASD with PAPVR preoperatively. Anomalous right pulmonary venous opening was located at right atrium, secundum type defect of atrial septum was present, and dual chambered left atrium without connection was also seen. Excision of the diaphragm and wide patch repair of ASD including right pulmonary vein were performed with good postoperative results. Herewith, we report this case with review of literatures.

A series of 132 consecutive cases of secundum type atrial septal defect operated from 1963 to 1980 in the department of Thoracic Surgery of Seoul National University Hospital is analysed. The ages of the patients ranged from 12 months to 57 years and the ratio of men to women was 1 to 1.4. Clinical analysis revealed 33 patients [26%] were asymptomatic and 15 patients [12%]had congestive heart failure. Hemodynamic analysis revealed that severe pulmonary hypertension which is the most serious risk factor is ASD developed in 10 patients [9%] and pulmonary artery pressure significantly increased after the age of 20 years. There were 10 patients with sinus venosus defect and 7 patients with partial anomalous pulmonary venous return. The operative mortality was 2.2%.
