The percutaneous transcatheter closure of secundum atrial septal defect has recently become an increasingly widespread alternative to surgical closure in many centers. Although immediate, short, and intermediate term results of percutaneous transcatheter septal closure are promising, the procedure is not free from inherent complications that could be lethal. We report a case of device embolization necessitating emergent surgical retrieval.

Ventricular septal rupture (VSR) is a rare but lethal complication of myocardial infarction. The event occurs 2~8 days after an infarction and often precipitates cardiogenic shock. Post myocardial infarction VSR is known for difficult to repair. Especially, Transmural myocardial infarction involved in the posterior VSD area, exposure of the affected site is difficult and postoperative mortality rate is high. We have experienced a case of a 75-year-old female patient who suffered posterior VSD due to acute myocardial infarction, and attained good result by approaching the lesion through right atrial incision and repaired the defect by using patch closure technique.

From February 1982 to December 1991, 49 neonates and 105 infants in less than 3 months of age underwent open heart surgery in Seoul National University Hospital. There were 98 males and 56 females, and their mean ages were 16 days in neonatal group and 67 days in early infant group. Their body weight and height were less than 3 percentile of normal developmental pattern. In order of decreasing incidence, the corrected conditions included Transposition of great arteries with or without ventricular septal defect [43], isolated ventricular septal defect [34], Total anomalous pulmonary venous return [21], Pulmonary atresia with intact ventricular septum [9] and others [47]. Various corrective or palliative procedures were performed on these patients; Arterial switch operation [36], patch closure for ventricular septal defect [34], Repair of total anomalous pulmonary venous return [21], RVOT reconstruction for congenital anomalies with compromised right ventricular outflow tract [17]. Profound hypothermia and circulatory arrest were used in 94 patients [ 61% ]: 42 patients [ 85.7% ] for neonatal group and 52 patients [ 49.5% ] for early infant group. The durations of circulatory interruption were within the safe margin according to the corresponding body temperature in most cases [ 84% ]. The hospital mortality was 36.4% ; 44.9% in neonatal group and 32.4% in infant group 1 to 3 months of age. The mortality was higher in cyanotic patients [ 46.6% ], in those who underwent palliative procedures [ 57.8% ], in patients whose circulatory arrest time was longer than safe periods [ 60% 0] and in patients who had long periods of cardiopulmonary bypss and aortic crossclamping. In conclusion, there has been increasing incidence of open heart surgery in neonates and early infants in recent years and the technique of deep hypothermia and circulatory arrest was applied in most of these patients, and the mortality was higher in cyanotic neonates who underwent palliative procedures and who had long cardiopulmonary bypass , aortic cross-clamping and circulatory arrest.

From April, 1984 to August, 1986, 214 cases of cardiovascular surgeries had been performed at Yeungnam University Hospital consisting 158 open heart surgeries and 56 non-open heart surgeries. The leading cardiac anomaly of open heart surgeries was ventricular septal defect which was 43% of congenital heart diseases, and most of remaining non-open heart surgeries were ligating patent ductus arteriosus. We had observed 33 postoperative complications such as wound problems, transient arrhythmia, postpericardiotomy syndrome, bleeding requiring reoperation and so on. 3 cases of surgical mortality were present [2 in congenital heart diseases and 1 in acquired heart disease], which resulting 1.9% of surgical mortality rate in the open heart surgeries.

From Aug. 1984 to May 1986, 116 cases of cardiovascular surgery including 85 cases of open heart surgery were performed at Korea Veterans Hospital. There were 108 congenital anomalies and 8 acquired valvular heart diseases. Among 108 congenital malformations 92 operations were done for acyanotic group, and 16 operations for cyanotic group. Thirteen cases of open heart surgery for infants or small children under 10kg of body weight were performed, which occupied 15.3 percent of total open heart surgery done in the same period. Common congenital cardiovascular anomalies were ventricular septal defect [40.7%], patent ductus arteriosus [29.6%], tetralogy of Fallot [12.[%], atrial septal defect [11.1%], and pulmonary stenosis [1.9%] in order of frequency. Valve replacement using lonescu-Shiley or Carpentier-Edwards valve was performed for 8 cases of acquired mitral valve disease, and valve replacement using St. Jude valve was done for a case of patent ductus arteriosus with severe mitral insufficiency. There was no mortality in acyanotic congenital malformations and acquired valve lesions, and 5 cases of mortality in cyanotic congenital malformations. Overall mortality was 4.3 percent for total cases and 5.9 percent for 85 cases of open heart surgery.

Background: Patients undergoing cardiac surgery require postoperative chest drainage. However, the drain is difficult to keep in place in children with congenital heart disease. Since 2015, at Kyungpook National University Hospital, the chest tube is removed on postoperative day 1 in patients who have undergone simple congenital cardiac surgery (i.e., closure of an atrial or ventricular septal defect). In this study, we evaluated the relationship between the duration of drain placement and the likelihood of pericardial effusion after congenital cardiac surgery. Methods: The medical records of patients who underwent closure of an atrial or ventricular septal defect at our hospital between January 2014 and December 2016 were reviewed. In total, 162 patients who received follow-up echocardiography and had information available on postoperative pericardial effusion after the repair procedure were enrolled. Results: Echocardiography was performed at a median of 5 days (range, 4 to 6 days) postoperatively before discharge from the hospital. Pericardial effusion occurred in 21 patients (13.0%), of whom only 3 (1.9%) had moderate or greater pericardial effusion, regardless of the drain duration. All patients improved during outpatient follow-up without invasive management. No patient had severe complications because of pericardial effusion. The duration of drain placement did not affect the incidence of postoperative pericardial effusion (p=0.069). Operative survival was 100%. Conclusion: Based on our study, we recommend removing the drain as soon as its role is complete, generally on postoperative day 1, because early removal does not increase the incidence of pericardial effusion in patients undergoing simple congenital cardiac surgery.

A 2-year-old female Maltese dog was referred with primary complaints of exercise intolerance and abnormal heart sound. Clinical and diagnostic investigation revealed split S2 and S4 gallop in the cardiac auscultation, tall P wave and left anterior fascicular block in the electrocardiogram, left atrial enlargement on the thoracic radiography, ostium primum atrial septal defect and cleft of the anterior leaflet of the mitral valve on the echocardiography. Based on those findings, the dog was diagnosed as the partial atrioventricular canal defect. Since the dog showed mild exercise intolerance, enalapril and furosemide were prescribed.
