심낭의 질환은 심혈관계에서 중요한 부분이지만 심낭압이나 심낭저류액의 조성에 대해서 연구된 바 는 거의 없다. 저자는 선천성 심장병(group A) 이나 후천성 심장병을(group B)을 가지고 있는 심장질환 환자에서 심장저류액의 정량, 정성적 분석에 대한 연구를 시행하였다. 심낭내압을 측정하기 위해 개심술 혹은 심장절개를 시행한 환자에게서 심방절개전 물을 채운 작은 18G polyethylene catheter를 심방내로 삽입하고 표준화된 monitor에 연결하여 측정하였다. 모든 수치는 동일 환자에게서 동시에 채취한 혈액에서 측정된 자료와 비교하여 분석하였다. 평균 심낭내압은 2.4mmHg였고 심낭저류액의 양은 group A에서 체표면적당 13cc, group B에서 17. 7cc였다. 그리고 세포수는 group A에서 138$\pm$l16/1, group B에서 230$\pm$ 13511였고 산도는 group A에서 2.Bg/dL, group B에서 3.IgldL로 혈장단백질농도에 비해 현저하게 낮은 농도를 나타냈다. LDH와 amylase는 혈청과 차이가 없었으나 group B에서 group A에 비해 야간 높은 수치를 보였다.

In 1980, 416 cases of open heart surgery were done in this Department with over all operative mortality of 12.3%. 1. There were 288 congenital anomalies consisting of 174 acyanotic and 114 cyanotic varieties, which showed operative mortality of 6.9% and 25.4% respectively. 2. There were 128 cases of acquired lesions, 124 valvular disease and 3 myxoma being the main lesions. 3. There were 128 cases of valve replacement with operative mortality of 7.8%. 4. The most frequently operated anomaly was VSD, 90 pure VSD and 21 cases were associated with one or 2 cardiac anomalies. Over all operative mortality in 111 VSD cases was 8.1% but in 90 pure VSD cases it was 6.7%. 5. Tetralogy of Fallot showed the highest incidence in cyanotic group with 88 cases, consisting of 68 pure and 20 with other cardiac anomalies. Over all mortality in 88 cases was 19.3% but in pure form 16.2%. 6. In 128 valve replacement cases over all mortality was 9.4%. There were 85 mitral, 11 aortic, 2 tricuspid, 21 mitral with aortic, 6 mitral with tricuspid, 3 mitral, aortic, and tricuspid valve replacement cases. For mitral valve replacement operative mortality was 5.9%. 7. Twenty-one cases of babies under 10kg body weight were operated on with over all operative mortality of 28.6%. Sixteen cases of VSD were found with operative mortality of 25%. 8. Among 128 cases of valve replacement 7 were under the age of 15 years and 12 were between 15 and 20 years old. Five pediatric cases underwent mitral valve replacement without mortality, 9 year old boy was the youngest among them. In this Department open heart surgery for infancy and complex anomalies showed still hip operative risk which should be improved in the coming years. For open heart surgery Shiley oxygenators and 2 sets of A-O de-lux 5 head roller pump were utilized exclusively. For valve replacement Ionescu-Shiley bovine pericardial xenografts were mainly used. In pediatric and rural patients Persantin with aspirin regimen was satisfactorily administered for anticoagulation after valve replacement. Routinely Coumadin was administered for one year after valve replacement* In patients who had thrombus on valve sites, chronic atrial fibrillation, and giant left atrium Persantin-Aspirin regimen was used when one year coumadin administration was discontinued.

Valve replacements in 82 children, aging up to 15 years[mean 11.67 years] were done at Seoul National University Hospital during 13 years period from 1974 to 1986. The patients were composed of 5] males and 31 females and 50 patients had acquired heart disease and 32 patients congenital heart disease. 75 patients received single valve replacements, 6 patients double valve replacements, 1 patient triple valve replacement, and among all of them, 11 patients redo-replacements. The bioprosthetic valves have been applied to 58 patients and prosthetic valve to 24 patients and the latter was the main artificial valve since 1984. Among the 69 patients who had definite post-operative records, the overall mortality was 27.5%[20.3% was early mortality and 7.2% late mortality] and the overall mortality was lowered to 4.3% since 1984. There were early post-operative complication rate of 26.1% and late complication rate 34.8%, and among the latter, the valve failure rate was 11.4% patient-year, and the thrombo-embolism rate 1.76%/patient-year. 55 patients among the survivals after post-operative 1 month, were received follow-up with various anticoagulating medication for total 2046 patient-months[mini-mum 1 month to maximum 90 month, mean 37.2*25.44 months] and actuarial survival rate was 82*8% at 5 years and valve failure free and thrombo-embolic free survival rate were 61*8% and 90*3% respectively. And among them, valve failure free survival `rate of tissue valve were 91*6% at post-operative 2 years, 78*3% at 3 years, 59*9% at 4 years, 54*10% at 5 years, 53*15% at 6 years, so markedly decreased at 3-5 years post-operatively. These results suggest that cardiac valve replacement in children have been effective therapeutic method though various problems are still remained, and the choice of valve should be prosthetic valve mainly due to its durability at the present.

Between 1985 and 1993, 29 children from 1 to 15 years of age have undergone cardiac valve replacements at Buchon Sejong Hospital. The patients were composed of 20 males and 9 females and 17 patient had congenital heart disease and 12 patients had acquired heart disease. Two of these patients have had second valve replacements due to paravalvular leakage and valve thrombosis. Single valve replacements were 29 and double valve replacements were 2. All the patients had received prosthetic valves except one. Among the 25 patients who had definite post-operative records, the overall mortality was 12%[4% was early mortality and 8% was late mortality].25 patients were followed up with coumadin anticoagulation for total 633 patient-months[minimum 2 months to maximum 93 months, mean 25.3 months] and actuarial survival rate was 88.5 $\pm$ 6.3% at 7 years and event free rate was 70.3 $\pm$ 11.7% at 7 years. These results suggest that pediatric valve replacements can now be performed at a low operative risk although various problems are still remained and the choice of valve is prosthetic valve mainly due to its durability at the present time.

배경: 심질환 환자는 심장의 구조적 혹은 기능적 결함으로 인하여 혈역학적 변화가 필연적으로 존재하며 그 결과 신체대사에 심각한 영향을 미치므로 수술전부터 산, 염기의 이상이 초래된다. 수술방법에는 필연적으로 비생리적인 체외순환법과 저체온법 및 혈액희석법과 같은 다양한 특수한 기법이 도입된다. 따라서 수술전 이미 존재하는 산 염기의 이상상태에서 체외순환이라는 수술적 침습에 의해 가해지는 shear압박으로 인하여 이미 악화된 상태의 산 염기 변화를 더욱 심하게 만들게 된다. 저자는 청색증을 포함한 소아심질환 환자와 선천성을 포함한 성인 심질환 환자에서 수술전 체외순환중, 수술후의 산, 염기의 치료지침을 얻기 위하여 본 연구를 시도하게 되었다. 대상 및 방법: 1997년 1월부터 1999년 5월가지 체외순환하에 개심술을 시행한 52례를 연구대상으로 하였다, 연구대상은 소아 및 성인 심질환, 선천성 및 후천성 심질환, 그리고 비청색증과 청색증심장병으로 구분하여 수술전, 수술중의 체외순환중, 그리고 수술후 각각 $\alpha$-stat 동맥혈 가스분석 결과를 분석, 비교하여 다음과 같은 결과를 얻었다. 결과: 수술전 산 염기 상태는 모든 심질환 환자들에서 대상성 대사성 산증이 기본적으로 존재하였다. 또한 성인 심질환과 후천성 심질환 환자군에서 저탄산가스 혈증이 존재하였으며, 청색증 심질환 환자군에서만 유일하게 대상성 호흡성 염기증이 있었다. 체외순환중에는 성인 심질환 환자군에서는 염기증만이 발생하였고 후천성 심질환 환자군에서는 정상상태의 산 염기 상태이었다. 반면에 소아심질환 환자군에서는 저 탄산가스 혈증 및 대상성 대사성 산증과 호흡성 염기증이 함께 공존하였다. 선천성과 비청색증 심질환 환자군에서는 각각 비대상성 호흡성 염기증 경향과 비대상성 호흡성 염기증이 발생하였다. 청색증 심질환 환자군에서는 체외순환중에 오히려 대상성 호흡성 산증과 대사성염기증이 발생하였다. 수술후 성인 심질환 환자군에서는 정상 상태의 산 염기 상태로 회복되었으며, 후천성심질환 환자군에서는 단지 표준 bicarbonate가 증가한 것만이 나타났다. 소아, 선천성, 비청색증 및 청색증 심질환 환자군에서는 모두 공통적으로 buffer base가 부족한 것으로 나타났다.

소아의 심장질환을 진단하는데 필수적인 진단도구로 자리를 잡아가고 있는 심초유파 검사는 신속한 확진과 그 방법의 비침습성으로 인하여, 소아 심장 클리닉에 심장질환 검사에 대한 의뢰가 증가되고 있는 실정이다. 그러나 심장질환이 의심되어 소아 심장 클리닉에 진단을 위하여 의뢰된 환아들에 대한 자료의 분석이 거의 없는 상태이므로, 심장질환의 진단을 위해 의뢰된 환아들의 특생에 대한 기초자료로 활용하고자 이들에 대한 자료를 비교 분석하였다. 대상 및 방법으로는 1998년 10월 1일부터 1999년 7월 10일까지 심장 질환이 의심되어 소아 심장 클리닉에 심장 검사를 위하여 의뢰되어 심초음파 검사를 시행한 428명을 대상으로 하였다. 이들 환아들의 자세한 병력, 흉부 방사선 검사, 심전도 검사의 결과와 필요한 경우에 추가 시행한 운동 부하 심전도, 24시간 심전도 및 심혈관조영술의 결과를 병력지를 이용한 후향적 조사룰 하였다. 의뢰 당시 환아의 성별 및 연령별 분포는 남아가 261례(61.0%), 여아가 167례(39.0%)로 남녀 비는 1.6:1이였으며, 1세 미만이 268례로 의뢰된 전체 환아 중 62.6%를 차지하였다. 의뢰된 이유로는 심잡음이 248례(57.9%)로 가장 많았으며 그 다음이 발열이 52례(12.1%), 심전도 이상이 43례(10.0%), 청색층이 33례(7.7%) 등의 순이었다. 의뢰 당시 의심된 심장질환 중 선천성 심장질환이 의심되어 의뢰된 경우는 302례(70.6%)였으며, 후천성 심장질환이 의심된 경우는 76례(17.8%), 부정맥이 의심되어 의뢰된 경우는 50례(11.6%) 로 나타나, 선천성 심장질환이 의심되어 의뢰된 경우가 가장 많았다. 의뢰 당시 의심되는 심장 질환별 임상적 양상 비교에서 선천성 심장질환이 의심된 경우는 심잡음이 248례(57.9%)로 가장 많았으며, 후천성 심장 질환이 의심된 경우는 발열이 52례(12.1%), 부정맥으로 의뢰된 경우는 심전도 검사의 이상 소견이 43례(10.0%)로 가장 많았다. 최종 진단 결과 선천성 심장병이 212례로 49,5%이었으며, 후천성 심장병이 59례로 13.9% 이었고, 부정맥이 13례로 3.0%를 차지하였고, 정상인 경우도 144례로 33.6%나 되었다. 결론적으로 신생아기에는 선천성 심장질환이 많았고, 유아기 이후에는 후천성 심장질환과 부정맥이 증가하는 추세를 보였다. 그러나 심초음파검사를 위해 의뢰된 환아 중 144례 (33.6%)가 심초음파검사에서 정상 소견을 나타내었으므로, 심음 청진에 대한 확신보다는 심초음파검사에 대한 의존도가 지나치게 높은 것으로 나타났다. 따라서, 선천성 심장질환의 감별을 위한 올바른 심음 청진에 대한 훈련이 다시 한번 강조되어야 할 것으로 사료된다.

To elucidate a potential contribution of endotheline-1[ET-1] to the genesis of pulmonary hypertension and postoperative pulmonary hypertensive crisis in the patients with heart disease, we measured plasma levels of the ET-1 during perioperative period of open heart surgery. In addition, we examined changes of ET-1 during perioperative period and correlations between ET-1 levels and hemodynamic variables. 12 patients including 5 acquired heart disease and 7 congenital heart disease patients were selected randomly as a study group, Group A and B, respectively. 6 patients proved not having heart or hemodynamic problem were selected as a control, Group C. 110 blood samples from pulmonary artery[ET-P] and radial artery[ET-S] were taken and assayed by Sep-pak extraction and RIA. ET-1 levels of Group A were ET-P, 3.94$\pm$5.31pg /ml, ET-S, 3.10$\pm$2.90pg/ml[p>0.05], Group B were ET-P, 1.63$\pm$0.62pg/ml, ET-S, 1.99$\pm$2.45pg/ml[p>0.05], Group C were ET-P, 1.97$\pm$2.02pg/ml, ET-S, 1.72$\pm$0.77pg/ml[p>0.05]. There were no statistically significant differences of ET-1 levels among the Group A, B, C[p>0.05]. There was no correlation between pulmonary artery pressure[PAP] and ET-1 level[p>0.05], and ET-1 levels were not increased even in the cases of pulmonary hypertensive criwis or low cardiac output syndrome, whereas significant correlation between ET-S and pulmonary vascular res-istance[Rp] [r=0.36, p<0.05], and negative correlation between ET-S and OS saturation of pulmonary artery[OS-P][r= -0.49, p<0.01] were identified. Another significant finding was peak increase of ET-1 levels in the postoperative period 1 hour[p<0.05] and then gra-dualy decrease through the postoperative period. In conclusion, ET-1 has no correlation with PAP, whereas correlation with Rp, and inverse correlation with OS-P. It is suggested that ET-1 is neither the direct causative substance of pulmonary hypertension nor pulmonary vasospasm but there must be increased production of ET-1 in chronic pulmonary hypertensive state. Counter-regulatory mechanism to ET-1 is speculated during the pulmonary vasospasm.
