Seventeen patients of the congenital pulmenic stenosis were operated at the department of Thoracic Surgery, Seoul National University Hospital. There were thirteen male and four females, and ranging from six to thirty years of age. And it's incidence was 2.7% of congenital heart disease cases that were operated on. (Total 628) Seven case of trilogy of Fallot were excluded. Two cases of bacterial endocarditis were found. Right heart catheterization was done in all patients. Average right ventricular pressure was $121{\pm}35.8$mmHg, pulmonary artery $20{\pm}6.8$mmHg, and RV-PA pressure gradient $98{\pm}34.5$mmHg. The preoperative average time interval of A2-P2 which was checked at phonocardiography was $0.08{\pm}0.016$second, and was reduced to $0.03{\pm}0.009$second postoperatively. One was operated by Varco's procedure, another one was done by Brock's procedure, and fifteen patients were done by open heart surgery with heart-lung machine. Pure valvular stenosis was found in sixteen and infundibular stenosis in one case. And the combining anormalies were two patent ductus arteriosus, two patent foramen ovale, and one tricuspid valve hypoplasia. Two expired postoperatively at the begining stage of cardiac surgery in this Department. The remaining fifteen showed excellent operative results.

Methods for the operative management of patent ductus arteriosus are now well established, and in the vast majority of children the circulatory shunt can be safely and effectively abolished by dividing the ductus or by closing it in continuity with ligatures and transfixing sutures. In adults, however, closure of patent ductus arteriosus may pose important technical problems, particularly when there are associated pulmonary hypertension, calcification, aneurysm and infective endocarditis. Under these circumstance, division or ligation is unusually hazardous because the diseased vessels often fracture or tear when sutures are placed in them. Then we closed the patent ductus arteriosus by use of cardiopulmonary bypass in 18 patients and ligated the ductus via thoracotomy in 18 patients from Jan. 1986 to May 1990. And we compared the results between two different methods. We concluded that ligation of ductus had a problem of rupture and transpulmonary internal suture closure of PDA had a problem of injury of recurrent laryngeal nerve.

This report describes our 10-year experience with intracardiac repair in 42 patients older than 16 year with tetralogy of Fallot. The mean age was 22.0$\pm$5.18 years[range 16~41]. The preoperative clinical manifestations were cyanosis & clubbing[93%], frequent URI [55%], anoxic spell[40%], pulmonary tuberculosis[21%], tuberculous empyema[7%], chronic renal failure[7%], congestive heart failure[7%] and subacute bacterial endocarditis [2%], etc. The previous shunt procedure for palliation had been performed in 7 patients. The type of VSD were typical perimembranous type[67%], total canal defect[28%] and combined type[5%]. The right ventricular outflow tract obstruction were combined type[69%], infundibular type[21%] and valvular type[10%]. Transannular patch was used in 50% of patients. Associated cardiovascular anomalies were ASD[33%], PFO[31%], Rt. aortic arch[10%], Lt. SVC[10%], single Rt. pulmonary artery, single Lt. coronary artery, ASI, proximal stenosis of Rt. pulmonary artery and anomalous systemic venous return, etc. Hospital mortality was 7.1%[3 cases]in overall. The causes of hospital deaths were revealed low cardiac output & acute renal failure[2 cases], postoperative bleeding[1 case]. There were 2 late deaths 3 & 68 months after surgery. Residual intracardiac shunt was detected in 2 patients. one patient was successfully reoperated and another patient had Qp /Qs ratio less than 1.5.

인제대학교 서울백병원에서 2례의 상간장막동맥에 발병한 감염성 동맥류를 경험하였다. 한 예는 세균성 심내막염에 병발한 감염성 색전증이 상간장막동맥에 발생하여 동맥류를 형성하였고 다른 예는 8개월 전에 발생한 살모넬라 장염에 합병한 일차적 동맥염이 원인이다. 이 동맥류들은 복부 초음파검시로 발견되었고 전산화단층촬영과 혈관조영술로 확진되 었으나 수술할 당시 2례에서 균배양은 되지 않았다. 두환자에서 장으로 순환되는 충분한 부행혈류가 있어 혈관재건 없이 동맥류를 절제만하여 성공적으로 수술하였다. 두환자에서 각각 일년과 9개월간 추적관찰중 동맥류의 재발은 없었다.

Ruptured aneurysms of the sinus of Valsalva are relatively rare, and the incidence seems to be higher in oriental than in western countries. Eight patients underwent operative treatment at Chonnam University Hospital from June, 1986 to May, 1992. Six of the patients were male and two female. Age ranged from eight to fifty six years. Associated cardiac lesions were common including AR and VSD in four patients respectively. Diagnosis was made by 2D-Echo and cine-angiogram. In six patients aneurysms of the sinus of valsalva ruptured from the right coronary sinus to the right ventricle and in two from right coronary sinus to the right atrium Direct closure of aneurysmal rupture and patch closure of VSD in four cases, resection of the aneurysm and direct closure in one case, direct closure of the fistula and AVR in two cases, direct closure in one case were performed. One patient combined with VSD, pulmonary hypertention and bacterial endocarditis underwent operation, but he died of sudden cardiac arrest the day after the operation. Operative results were relatively good in the other patients.

In this study, a safety evaluation was conducted to confirm if the Enterococcus faecium CKDB003 strain obtained by selection from a mixed fermentation of fruit and milk is suitable for use as a probiotic. The MIC value for the 10 antibiotics specified in the EFSA guidance was below the acceptable cut-off value. The antibiotic resistance genes aac(6')-li, eatAv, and msr(C) exist by whole genome sequencing, but are in the chromosome and not in the plasmid, thus confirming that there is no possibility of transmission to other microorganisms. It was confirmed that cytolysin (cylA, cylB, cylI, cylL-l, cylL-s, cylM, cylR1, cylR2), aggregation substance (asa1, asp1), collagen adhesion (ace), enterococcal surface protein (esp), endocarditis antigen (efaA), hyaluronidase (hyl) and gelatinase (gelE) were not present in the genome by examining the genes of factors related to virulence. Also, the biochemical analysis showed no toxic enzyme activities, and no virulence genes were detected by the PCR method. Thus, the E. faecium CKDB003 strain can be safely used as a health functional food probiotic, based on the results of the safety assessment.

Ventricular septal defect[VSD] associated with aortic regurgitation[AR] represents 2 to 7.5% of all VSD which is most common congenital heart disease. The aortic valve may by normal in infants with VSD, but the aortic regurgitation may be developed in these patients later. The aortic valve became fibrotic, thickened, deformed and prolapsed, so these late deformities require to be corrected with plication, valvuloplasty or aortic valve replacement [AVR]. There are some controversy between the early repair of VSD alone and the late repair of VSD and aortic valve till now. From December 1971 to August 1983, we had experienced 24 patients of VSD associated with AR which constitute 6.5% of our total patients with VSD. The VSD was subpulmoary [type I] in 14[58.3%], subcristal [type II] in 8[33.3%], atrioventricular canal type[type III] in 1, and combine of type I and II in 1. Patch repair of VSD was made in 15 patients and direct suture of small VSD in 9.14 patients had aortic plication of valvuloplasty and 9 had AVR accompanying VSD repair, and 1 patient had VSD closure alone. The postoperative courses of these patients were uneventful except in some cases. A patient who was undertaken AVR with Starr-Edwards ball valve and VSD closure, died due to left ventricular failure and low cardiac output syndrome. Follow up shows, in 14 patients with aortic plication or valvuloplasty, AR was developed in 9. In 9 AVR, there were two later complications which were paravalvular leakage in one and re-AVR due to subacute bacterial endocarditis in another.

From January 1989 to December 1993, cardiac catheterization and open heart surgery for ventricular septal defect closure were performed in 115 pediatric patients who were selected as meeting the criteria for elective closure of restrictive ventricular septal defect. These criteria included age greater than 1 year and less than 15 years, no evidence of congestive heart failure, Qp/Qs 2.0, pulmonary artery systolic pressure 35mmHg, and no associated cardiac anomalies. Mean age of patients was 5.25$\pm$ 3.53, and 72 patients were male, 43 patients were female[male:female=1.9:1 . Mean systolic pulmonary artery pressure was 19.66$\pm$4.79mmHg, and mean pulmonary to systemic flow ratio was 1.27$\pm$ 0.28. Aortic cusp prolapse was present in 30 patients [26% , aortic insufficiency was present in 1 paient, and 1 patient had prior bacterial endocarditis. There were no instances of complete atrioventricular dissociation, reoperations for bleeding, or reoperations for recurrent ventricular septal defect, but wound infection was present in 1 patient, and there were 7 patients who had the hemodynamically insignificant remnant shunt. There were no early or late deaths or major morbidity.

Twenty-seven patients with double-outlet right ventricle underwent complete intracardiac repair between 1978 and 1983, June, at Seoul National University Hospital . Although definite aorto-mitral discontinuity was discovered in 20 patients, both great arteries arose wholly or mostly from the right ventricle in all cases. There were 17 cases with subaortic VSD, 6 with subpulmonic, 2 with doubly-committed, and 2 with non-committed VSD. Pulmonary stenosis was present in 21 patients. Intraventricular baffle repair was applied in 23 patients. Three patients required extracardiac conduit to establish continuity between right ventricle and pulmonary artery, and modified Fontan operation was performed in one patient. Over-all mortality rate was 37.0%, but recently 4 of 15 died [26.7%]. One late death occurred from infective endocarditis. Incremental risk factors were small patient size, subpulmonic or non-committed VSD, presence of PS, coronary artery anomalies, associated valvular lesion and other complicated anomalies. However, great artery relationship, restrictive VSD and transannular patch were not risk factors. No instances of complete heart block occurred. Of the survivors, all showed complete or in complete right bundle branch block and in one patient intermittent ventricular tachycardia had developed. The important cause of death was low cardiac output syndrome.
