Systemic lupus erythemotosus (SLE) is an autoimmune disorder with dermal, renal, and cardiac manifestations. It frequently has cardiovascular complications such as pericarditis, myocarditis, and valvular heart diseases. Valvular heart diseases in SLE comes mainly in the form of mitral or aortic insufficiencies. Report of aortic stenosis is extremely rare. Surgical treatments of valvular heart disease in SLE are not done frequently because of complications in other organs. Aortic stenosis developed in a 59 year-old woman with SLE, and aortic valve replacement was done successfully.

Central anticholinergic syndrome is defined as an absolute or relative reduction in cholinergic activity in the central nervous system and has a wide variety of manifestations. It is associated with almost any drug given during anesthesia, except neuromuscular relaxants, and treated with the cholinesterase inhibitor physostigmine. The diagnosis of central anticholinergic syndrome is often made when symptoms resolve promptly after the administration of physostigmine. We present a case of a central anticholinergic syndrome diagnosed by treatment with physostigmine, in a patient who received closure of patent foramen ovale associated with stroke.

Congenital polyvalvular disease is a connective tissue disorder affecting more than one heart valve with variable involvement of the entire valvular and subvalvular apparatus. It is frequently associated with the Trisomy 18 and trisomy 13-15 or ventricular septal defect and patent ductus arteriosus. We present an isolated case of congenital polyvalvular disease in a new born baby with a review of the pertinent literatures, which has not been described in Korea. The mass was discovered as a right atrial mass in the prenatal ultrasonography and it was thought to be either a hematoma or a myxoma in the preoperative echocardiography. Microscopic examination of the surgically resected mass showed irregular thickening, nodulation, and additional features of calcification and ossification in the valvular connective tissue on the body of anterior and septal leaflet of tricuspid valve. Congenital polyvalvular disease should be included in the differential diagnosis in cases showing valvular calcification or ossification in the fetal echocardiography.

Background: From Sept. 1985 to Sept. 1997, 2,000 cases of open heart surgery(OHS) were performed in the Department of Thoracic & Cardiovascular Surgery, Pusan Paik Hospital, College of Medicine, Inje University. Material and Method: Among the total of 2,000 cases of OHS, 1532 cases were congenital heart disease(CHD) and 468 cases were acquired heart disease(AHD). The age distribution was 9 days(4.0kg) to 68 years in CHD and 11 to 66 years in AHD. In 1532 cases of CHD, there were 1403 acyanotic cases and 129 cyanotic cases. Result: The CHD cases consisted of 940 ventricular septal defects(61.4%), 324 atrial septal defects(21.1%), 112 tetralogy of Fallot(7.3%), 46 pulmonary stenosis(3%), 38 endocardial cushion defects(2.5%), 15 valsalva sinus ruptures(1%), 4 transposition of great arteries (0.3%), 4 double outlet right ventricles(0.3%), and etc. Corrective operations were applied for congenital heart disease with a result of 3.1% hospital mortality. Of 468 AHD, 381 cases were valvular heart diseases, 48 ischemic heart diseases, 12 cardiac tumors, 8 annuloaortic ectasias, 16 dissecting aortic aneurysms and etc. In the 381 valvular heart diseases, there were 226 single valve replacements(36 aortic valve replacements(AVR), 188 mitral valve replacements(MVR), and 2 tricuspid valve replacements(TVR), among these were 71 cases of double valve replacements(AVR & MVR), 54 cases of MVR with tricuspid valve annuloplasty(TVA), and 18 cases of AVR, MVR with TVA. The total implanted prosthetic valves were 466. In MVR, 123 St. Jude Medical valves, 90 Carpentier-Edwards valves, 65 CarboMedics valves, 42 Sorin valves and 16 other valves were used. In AVR, 68 St. Jude Medical valves, 36 CarboMedics valves, 14 Carpentier-Edwards valves and 9 other valves were used. Coronary Artery Bypass Surgery(CABG) were performed in 48 cases. The patterns of bypass graft were 14 patients of single vessel graft, 21 patients of two vessels graft, 10 patients of three vessels graft and 3 patients of four vessels graft. Conclusion: The hospital operation mortality rate of congenital acyanotic, cyanotic and acquired heart diseases were 2.0%, 15.5%, and 5.1% respectively. The overall mortality rate was 3.6%(72/2,000).

The incidence of degenerative valve disease also increasing with the increasing life expectancy of the elderly population. Rheumatic valve disease is decreasing gradually and the incidence of calcified degenerative aortic stenosis (AS) is growing. Echocardiography is a very important tool for evaluating the prognosis and treatment method as well as the time of operation and diagnosis of heart valve disease. When evaluating valvular heart disease, 2-dimensional echocardiography, which observes all heart valves in detail, should take precedence. Understanding the clinical findings of degenerative valve disease and performing precise echocardiography are extremely important. In addition, an assessment of the severity of aortic stenosis is necessary to determine the surgical indications. An assessment of the severity by echocardiography was explained with three cases of degenerative aortic stenosis. To perform echocardiography accurately, it is necessary to understand degenerative valve disease and its clinical findings accurately.

From Feb. 1985 to Aug. 1996, 450 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. In 450 cases of open heart surgery, 222 cases(49.3%) were congenital heart diseases and 228 cases(5 .7%) were acquired heart diseases. In 222 cases of congenital heart diseases, there were 201 cases of acyanotic heart disease and 21 cases of cyanotic heart diseases. Among the 228 cases of acquired heart diseases, most cases were valvular heart diseases in which 206 valves were implanted. There were 32 cases of ischemic heart disease and the average graft anastomoses were 2.37 sites per operation. The operative mortality of congenital and acquired disease was 9.0% and 10.l% respectively and then overall mortality rate was 9.6% .

배경: 승모판막 질환에 동반된 심방세동의 경우 그 기간이 길면 승모판막 질환을 수술하여도 동성 율동으로 전환될 가능성이 매우 적다. 본 연구는 승모판막 질환에 동반된 심방세동에 대한 변형 Maze 수술후 장기 결과와 심방세도의 재발에 미치는 요인을 조사 하고자 하였다. 대상 및 방법: 1990년부터 1996년까지 승모판막 질환과 동반된 심방세동으로 외과적 요법을 시행받은 35명의 환자를 대상으로 하였다. 심방세동의 평균 유병기간은 평균 7.7$\pm$4.5년이었고 수술은 승모판막 대치술 34례(재수술 3례)와 승모판막 성형술 1례를 시행하였고 승모판 질환 수술 외에 동반 수술로는 삼첨판륜 성형술 4례, 삼첨판막 대치술 3례 였다. 심 방세동에 대한 수술은 좌측 폐정맥 부위는 격리하지 않는 변형 Maze 수술을 시행하였다. 수술 후 동성 율동으로 회복여부, 심방세동의 재발에 미치는 요인과 장기 결과를 분석하였다. 결과: 수술 직후 2례를 제외한 33례(93.9%)에서 동성율동으로 돌아왔으나 수술 후 퇴원 전에 12례에서 심방세동이 재발되었다. 수술환자중 1례에서 수술 후 3일에 동성 정지에 따른 심정지가 발생하여 소생되었으나 뇌손상으로 수술 후 15일에 사망하였다. 심방세동이 재발된 경우 수술 후 약 2개월에서 6개월 사이에 항부정맥 약물(mquinidine)과 전기적 제세동으로 치료하여 12례중 10례에서 동성 율동으로 돌아온 환자는 항부정맥 약물을 모두 중단하 였으며, 수술 후 3년에서 9년(평균 71.1$\pm$17.5개월) 추적 관찰 중 9례에서 심방세동이 재발되어 장기간 동성 율동이 유지된 환자는 34명중 25명으로 73.5%이었다. 승모판 질환이 있던 환자에서 수술 후 심방세동의 재발에 미치는 요인들을 조사한 결과 수술전 심방세동의 기간(동성율동 유지군 : 재발군=6.3년 : 10.3년, P=0.008)과 수술 전 단순 흉부 X선상 심흉비율(0.58 : 0.72, p=0.009)은 통계학적으로 유의하게 나타났으나 심초음파 검사상 좌심방의 직경(57.2mm : 77.4mm, p=0.106)은 통계학적 유의성이 없었다. 결론: 심방세동이 있는 환자에서 동반 질환 수술시 병행하여 수술한다면 정상 동성 율동으로 회복될 기회를 증가시킬 수 있는 유용한 수술법으로 생각된다. 그러나 수술후 재발률을 감소시키기 위하여 적절한 술기의 변형에 대한 연구와 약물요법의 병행을 고려하여야 할 것으로 사료된다.

The quadricuspid aortic valve is a rare congenital cardiac morphology. In regard to the hemodynamics of the quadricuspid aortic valve, the regurgitation is most common, the regurgitation accompanying the stenosis or pure stenosis are rare. We report hear a case with quadricuspid aortic valve disease which has been known to be extremely rare.

A 17-year-old male patient was referred with symptoms of dyspnea. Multi-detector computerized tomography (MDCT) and echocardiography evaluation revealed quadricuspid aortic and pulmonary valves, an atrial septal defect (ASD), and pulmonary stenosis. We closed the ASD using a bovine patch and performed a commissurotomy of the pulmonary valve. Quadricuspid semilunar valves are very rare congenital abnormalities that are reported to occur nine times more frequently in the pulmonic valve than in the aortic valve. According to the Hurwitz Roberts classification, the aortic valve was type A, and the pulmonic valve was type B. The aortic valve normal function, but the pulmonic valve was stenotic and had abnormal function.

Rheumatic valvulitis produces at least three distinct pathologic changes, the degree varying widely among the patients: fusion of the valve leaflets at the commissures; fusion and shortening of chordae tendinae: and fibrosis of the leaflets with subsequent stiffening, contraction and calcification. The most extensive changes usually are seen in patients with recurrent attacks of rheumatic fever. We studied on outcome of the surgical treatments of rheumatic valvular diseases that have been experienced for 12 years since 1982 at Pusan National University Hospital. The diagnoses were made by rheumatic fever history, echocardiographic findings, gross operative findings and microscopic findings. Total 502 patients were performed surgery for valvular heart diseases and 440 patients of rheumatic origin have bene analysed. There were more female than male patients as 1.3:1, and the mean age was 37.8 years old. 96.3% of them affected to the mitral valve, 19.8% to aortic valve, 16.3% affected to the tricuspid valve. Most of them underwent valve replacement, and valve repair was done in 3.9% of patients. There were 36 hospital deaths(8.2%) mainly from low cardiac output syndrome, and 15 late deaths equally due to embolism and hemorrhage. Follow up was 90.1% completed(2890 patient- year). Linealized rates of late complication events are follows : thromboembolism 1.3% per patient year; anticoagulant related hemorrhage 0.8% per patient year. Overall actuarial survival including hospital mortality was 92.7＋/-2.9% in 1 year, 88.0＋/-4.5% in 5 year, 82.3＋/-7.7% in 10 year. We conclude that the rheumatic disease is still the most frequent and the most important cause of heart valve disease. So more intensive study is needed in spite of the abrupt decreasing rate of rheumatic fever in U.S.A. and other industrial country.
