  • Double outlet right ventricle (DORV) is a relatively common congenital heart disease in which both great arteries are connected completely or predominantly to the morphologic RV. Unlike other congenital heart diseases, DORV demonstrates various anatomic and hemodynamic subtypes, mimicking ventricular septal defect, tetralogy of Fallot, transposition of the great arteries, and functional single ventricle. Because different surgical strategies are applied to different subtypes of DORV with ventricular septal defects, a detailed assessment of intracardiac anatomy should be performed preoperatively. Due to high spatial and contrast resolutions, cardiac CT can provide an accurate characterization of various intracardiac morphologic features of DORV. In this pictorial essay, major anatomic factors affecting surgical decision-making in DORV with ventricular septal defects were comprehensively reviewed using three-dimensional cardiac CT data. In addition, the surgical procedures available for these patients and major postoperative complications are described.

  • One hundred cases of open heart surgery were done at this Department in 1977. There were 65 congenital anomaly and 35 acquired diseases. Out of 65 cases of congenital malformation 35 acyanotic and 30 cyanotic cases were found. Fifteen cases of ventricular septal defect and 29 tetralogy of Fallot were noted eight patients expired out of 65 congenital anomaly [12.3%] , 4 out of 35 acyanotic [11. 4%] and 4 among 30 cyanotic anomaly[13.3%]. Among 35 cases of acquired heart disease 3 atrial myxoma [2 left and one right] and 32 valvular lesions were noted. In two cases open mitral commissurotomy, and in 30 valve replacement were done. Twenty-two single valve and 8 double valve replacement were done. Seven patients expired out of 30 patients [23.3%]. Among 22 single valve replacement cases 2 and among 8 double valve 5 died. ~ In eighteen mitral valve replacement cases 2 deaths occurred. One mitral insufficiency patient who expired suffered from severe pulmonary` hypertension [PA=120/67mmHg], tricuspid insufficiency and a large ventricular septal defect. The patient underwent mitral valve replacement, tricuspid annuloplasty and patch closure of ventricular septal defect. Over all mortality rate for 100 open heart surgery cases was 15%. Since 1977 open heart surgery cases were done routinely in this institution and cases are increasing rapidly. With present rapid improvement of economical status and introduction of medical insurance system, open heart surgery will be firmly established in Korea in the very near future.

  • Between April, 1984 and September, 1988, 459 patients underwent cardiovascular surgery at the Yeungnam University Hospital. Of these, 355 cases were open heart surgeries and 104 cases were non-open heart surgeries. There were 237 patients of acyanotic congenital cardiac anomalies, 40 patients of cyanotic congenital cardiac anomalies, and 85 patients of acquired heart diseases. The sex ratio of cardiovascular diseases was represented as 1:1.3 in male and female. The age distribution was ranged from 1 day to 65 years old. The common congenital cardiovascular anomalies were ventricular septal defect(38.7%), patent ductus arteriosus(25.5%), atrial septal defect(20.7%), Tetralogy of Fallot(8.3%), and pulmonary stenosis(2.4%) in order of frequency. Among 87 acquired cardiovascular diseases, 81 patients underwent operation for cardiac valvular lesions. 51 patients had mitral valve replacement and 13 patients had aortic valve replacement and 17 patients had double valve replacement. The overall mortality of cardiovascular surgery was 3.3% and mortality of open heart surgery was 3.9%.

  • Purpose: This study was performed to determine the clinical features of full-term infants with hypoxemia detected by pulse oximetry and to establish the diagnosis of critical congenital heart disease (CCHD). Methods: We retrospectively reviewed the medical records of neonates who had been admitted to the neonatal intensive care unit within 2 weeks of birth at Korea University Ansan Hospital between January 2013 and October 2017 (n=450). We classified these neonates based on the presence of hypoxemia at admission and investigated neonatal characteristics, initial symptoms, echocardiographic findings, and final diagnosis associated with hypoxemic diseases. Results: Of 450 term infants, 265 infants (58.9%) were identified hypoxemia by pulse oximetry at admission. The most common symptoms of them were cyanosis and tachypnea. Among them, 80.1% of infants (214/265) were diagnosed with respiratory tract disease and 8.3% of infants (22/265) had congenital heart disease. Thirteen infants (13/265, 4.9%) had CCHD and were treated with urgent surgery or transcatheter intervention within 28 days of birth. Majority of infants with respiratory tract disorder were transferred from hospital immediately after birth, but 46.1% of infants (6/13) with CCHD remained asymptomatic after birth and were admitted after 48 hours after birth. In addition, other hypoxemic illnesses were identified as neonatal infectious and neurological diseases. Conclusion: This study showed the importance of assessment in neonates with hypoxemia, including those diagnosed with CCHD. The possibility of CCHD should be considered in the differential diagnosis in neonates demonstrating hypoxemia after 48 hours of birth. A larger prospective study is needed to assess the effectiveness and outcomes of pulse oximetry for neonatal screening in Korea.

  • Symptomatic pulmonary arterial hypertension (PAH) in patients with isolated atrial septal defect (ASD) is rare during infancy. We report a case of isolated ASD with severe PAH in an infant who developed airway obstruction as cardiomegaly progressed. The patient presented with recurrent severe respiratory insufficiency and failure to thrive before the repair of the ASD. Echocardiography confirmed volume overload on the right side of heart and severe PAH (tricuspid regurgitation [TR] with a peak pressure gradient of 55 to 60 mmHg). The chest radiographs demonstrated severe collapse of both lung fields, and a computed tomography scan showed narrowing of the main bronchus because of an intrinsic cause, as well as a dilated pulmonary artery compressing the main bronchus on the left and the intermediate bronchus on the right. ASD patch closure was performed when the infant was 8 months old. After the repair of the ASD, echocardiography showed improvement of PAH (TR with a peak pressure gradient of 22 to 26 mmHg), and the patient has not developed recurrent respiratory infections while showing successful catch-up growth. In infants with symptomatic isolated ASD, especially in those with respiratory insufficiency associated with severe PAH, extrinsic airway compression should be considered. Correcting any congenital heart diseases in these patients may improve their symptoms.

  • From July 1984 to September 1990, 316 patients of congenital heart diseases were operated and 15 patients died. Hospital mortality was 4.75%. Five patients of 73 PDA had residual shunt after operation: 4 were ligated under support of Dacron patch, 1 was closed through the pulmonary arteriotomy under CPB. 3 patients were reoperated. No patient had residual shunt or reopening among the patients of simple ligation or division and suture. During the ligation of PDA, Dacron patch for protection from tearing may disturb the complete interruption of shunt. If the tissue around the ductus arteriosus looks weak or fragile, division and suture may be more reliable other than ligation with supporting patch. If the septal leaflet of tricuspid valve is adherent around the VSD, remained opening of VSD may be closed with simple suture directly. In these cases, the incidence of postoperative residual shunt is as high as the incidence of more large VSD closed with patch [10.9%: 9.6%]. During the direct closure of remained opening of VSD, another leaking route should be looked for carefully beneath the septal leaflet of tricuspid valve.
