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.

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.

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.

A 43 years old female patient who had been diagnosed as having valvular heart disease but had not received any treatment invited and admitted due to progressive dyspnea. She was diagnosed as having aortic and mitral valve stenosis and regurgitation. Neurologic symptoms developed suddenly therefore, surgery was performed. In the operation field, there were many fungating tissue around the mitral valve annulus and left atrial wall. After operation, no neurologic symptoms were observed and pathologist revealed that fungating tissue was papillary fibroleastoma. The patient recovered and was followed in outpatients department.

Background: The detection of circulating microemboli by transcranial Doppler ultrasonography (TCD) has the potential to select the patients with high risk for future symptomatic brain embolism. We prospectively evaluated the positive rate and the frequency of microembolic signals (MES) before and after the heart valve surgery (HVS). Material and Method: Fifty in-patients with heart valve disease were enrolled in this study. Patients with history of previous stroke or heart valve surgery were excluded. Two unilateral TCD monitoring sessions were peformed from middle cerebral artery for 1-hour, before and after HVS. Result: Mechanical Heart valves were implanted in 28 patients, tissue valves were implanted in 10 patients, and remaining 12 patients received mitral valve repair. Positive rate of MES was significantly increased after HVS (50%), compared to that of before HVS (8%, p=0.00). There was no relation between MES after HVS and intensity of anticoagulation, cardiac rhythm, patients' age, and history of hypertension. The positive rate of MES after implantation of mechanical heart valve (71.4%) was significantly higher than those after implantation of tissue valve or mitral valve plasty (p=0.002). Conclusion: Positive rate of MES was increased significantly after the implantation of HVS. The changes of MES in those with mechanical prosthesis may be related to the increased risk or embolism after Hvs.

Patients with concomitant surgical diseases of the heart and lungs are a therapeutic challenge to cardiothoracic surgeons. A 59-year-old woman underwent right middle lobectomy for lung cancer and redo double valve replacement with tricuspid annuloplasty simultaneously. Concomitant operation is a safe procedure and might allow prompt correction of both conditions, thereby sparing the patient a second major thoracic procedure with its attendant risks.

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.

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% .
