Between Feb. 1990 and Aug. 1993, 180 cases of the open heart surgery were performed under cardiopulmonary bypass in the Department of Thoracic & Cardiovascular surgery, Gil General Hospital. There were 83 cases with congenital heart diseases [CHD] and 97 cases with acquired heart diseases [AHD]. The CHD consisted of 78 acyanotic[mortality: 3.8 %] and 5 cyanotic cases with heart anomaly[mortality:l case]. The AHD were 97 cases, which contained 53 valvular, 27 ischemic heart diseases, 10 aortic diseases, 5 cases with myxoma, 1 case with post-infarct VSD, and 1 case with removal of infected pacing wire in right ventricle. In the 53 valvular heart diseases, there were 45 cases with valve replacement[MVR 27, AVR 9,MVR + AVR 9] and 8 cases with valvuloplasty. The number of the implanted prosthetic valves were 53. In MVR, 25 St. Jude, 6 Sorin, 3 Carpentier-Edward and 2 Intact medical valves were used. In aortic position, 13 St. Jude, 3 Sorin and 1 Intact medical valves were applied. The operative mortality was 5.6 % [3/53]. The annuloplasty applying artificial ring was performed in 17 patients[4 cases associated with MVR] and the number of the implanted ring was 19, which included 14 Duran ring[10 mitral, 4 tricuspid] and 5 Carpentier ring [3 mitral, 22 tricuspid]. In the 27 ischemic heart diseases, there were 9 cases with left main coronary artery lesions, 7 one vessel, 5 two vessels, and 6 three vessels. Average number of anastomosis was 2.8 per patient. The operative mortality was 14.3 % [4/27]. Among the 10 patients with aortic diseases, 7 cases were aortic dissection[type A: 5, type B: 2] and 3 cases were descending thoracic aortic aneurysm. The operative morality occurred in 3 cases. The overall mortality and the operative mortality of congenital and acquired heart disease was 7.8 %, 4.8% and 10.4%, respectively.

For years, physicians and anatomists have been interested in the heart that has one functioning ventricle. Various terms have been suggested for this entity including single ventricle, common ventricle, double-inlet left ventricle, cor biatriatum triloculare, and primitive ventricle. In this report, the term "single ventricle" is utilized as suggested by Van Praagh, and is defined as that congenital cardiac anomaly in which a common or separate atrioventricular valves open into a ventricular chamber from which both great arterial trunks emerge. An outlet chamber, or infundibulum, may or may not be present and give rise to the origin of either of the great arteries. This definition excludes the entity of mitral and tricuspid atresia. An 11 year old cyanotic boy was admitted chief complaints of exertional dyspnea and frequent upper respiratory infection since 2 weeks after birth. He was diagnosed as inoperable cyanotic congenital heart disease, and remained without any corrective treatment up to his age of 11 year when he suffered from aggravation of symptoms and signs of congestive heart failure for 2 months before this admission. On 22nd of May 1979, he was admitted for total corrective operation under the impression of tricuspid atresia suggested by a pediatrician. Physical check revealed deep cyanosis with finger and toe clubbing, and grade V systolic ejection murmur with single second heart sound was audible at the left 3rd intercostal space. Development was moderate in height [135 cm] and weight[28Kg]. Routine lab findings were normal except increased hemoglobin [21.1gm%], hematocrit [64 %], and left axis deviation with left ventricular hypertrophy on EKG. Cardiac catheterization and angiography revealed 1-transposition of aorta, pulmonic valvular stenosis, double inlet of a single ventricle with d-loop, and normal atriovisceral relationship [Type III C solitus according to the classification of Van Praagh]. At operation, longitudinal incision at the outflow tract of right ventricle in between the right coronary artery and its branch [LAD from RCA] revealed high far anterior aortic valve which had fibrous continuity with mitral annulus, and pulmonic valve was stenotic up to 4 mm in diameter positioned posterolaterally to the aorta. Ventricular septum was totally defective, and one markedly hypertrophied moderator band originated from crista supraventricularis was connected down to the imaginary septum of the ventricular cavity as a pseudoseptum of the ventricle. Size of the defect was 3X3 cm2 in total. Patch closure of the defect with a Teflon felt of 3.5 x 4 cm2 was done with interrupted multiple sutures after cut off of the moderator band, which was resutured to the artificial septum after reconstruction of the ventricular septum. Pulmonic valvotomy was done from 4 mm to 11 mm in diameter thru another pulmonary arteriotomy incision, and right ventriculotomy wound was closed reconstructing the right ventricular outflow tract with pericardial autograft of 3 x 4 cm2. Atrial septal defect of 2 cm in diameter was closed with 3-0 Erdeck suture, and atrial wall was sutured also when rectal temperature reached from 24`C to 35.5`C. Complete A-V block was managed with temporary external pacemaker with a pacing rate of 110/min. thru myocardial wire, and arterial blood pressure of 80/50 mmHg was maintained with Isuprel or Dopamine dripping under the CVP of 25-cm saline. Consciousness was recovered one hour after the operation when his blood pressure reached 100 /70 mmHg, but vital signs were not stable, and bleeding from the pericardial drainage and complete anuria were persisted until his heart could not capture the pacemaker impulse, and patient died of low output syndrome 320 min after the operation.

온전한 심실중격을 가진 폐동맥 폐쇄증은 병변의 다양성으로 인하여 여러 가지의 외과적 술식이 요구되는 질환이다. 본 연구에서는 온전한 심실중격을 가진 폐동맥 폐쇄증으로 수술을 받은 환자들을 대상으로 수술 방법에 따른 결과 및 장기 성적에 대하여 알아보고자 하였다. 대상 및 방법: 1992년 1월부터 2004년 6월 사이에 외과적 치료를 받았던 총 38명의 환자들을 대상으로 하였다. 평균 연령은 18일$(2\~382일)$이었으며, 삼첨판막륜 크기의 평균 Z값은 $-3.1(-5.6\~0.8)$이었다. 우심실-관상동맥루를 동반한 환자는 13명$(36\%)$이었으며, 우심실의존 관상동맥순환을 보인 환자는 4명$(11\%)$이었다. 평균 추적기간은 55개월(3개월-12.2년)이었다. 결과: 24명의 환자들에서 우심실 감압술이 시행되었고, 14명의 환자들에서는 체폐동맥 단락술만이 시행되었다. 우심실 감압술을 시행받은 환자들의 평균 삼첨판막륜 Z-값은 $-2.2\pm1.1$로 체폐동맥 단락술만 시행받은 환자들의 평균 Z값 $-4.8\pm0.6$보다 컸다(p=0.000). 5명$(13\%)$의 조기 사망과 1명의 만기 사망이 발생하였다. 조기 사망은 우심실 감압술을 시행받은 환자들 중 3명$(13\%)$, 체페동맥 단락술만 시행받은 환자들 중에서 2명$(14\%)$이 발생하였다(p=1.0). 양심실 교정을 받은 환자가 12명$(32\%)$, 단심실 교정을 받은 환자가 8명$(21\%)$, 부분양심실 교정을 받은 환자가 4명$(11\%)$, 최종 교정을 기다리고 있는 환자가 9명$(24\%)$이었다. Kaplan-Meier방법으로 산출한 5년 및 8년 생존율은 $83.2\%$이었다. 결론: 대부분의 사망은 초기 수술 후에 발생하였으며, 양심실 혹은 단심실 교정을 의도한 군간에 사망률의 차이는 없었다. 전체적인 장기 생존율은 비교적 양호하였다. 환자 각각의 삼첨판막륜 및 우심실 크기, 그리고 관상동맥 이상 유무를 정확히 평가하여 적절한 수술 방법을 적용하면 조기 사망률의 개선을 기대할 수 있으리라 생각한다.

심실중격이 온전한 폐동맥 폐쇄증은 그 해부학적 형태의 다양성으로 말미암아 여전히 획일화된 치료 전략이 결정되어 있지 않으며, 따라서 수술 사망률, 유병률 또한 높다. 본 연구는 1987년부터 1995년까지 서울대학교병원 어린이병원 흉부외과에서 경험한 심실중격이 온전한 폐동맥 폐쇄증 환아 34례를 대상으로 하였으며, 환아들의 평균연령 및 핑균 체중은 각각 57.2(범위, 3-208) 일 및 4.1(범위, 2.3-6.8) kg이었다. 술전 삼첨팔륜직경의 Z-치와 우심실강의 크기는 통계적으로 의미있는 상관관계를 보여주었다(n=27, r=0.68, p<0.05). 관상동맥-우심실루는 3례에서 확인되었으며 그 중 1례에서는 우심 실-의존성 관상동맥 순환의 양상이 의심되었다. 총 수술 사망률은 23.5%(8134)였으나 90년대 들어서는 16.6%(4/24)로 현저히 감소하는 양상을 보였다. 체폐동맥 단락술후 시행한 양방향성 체정맥-폐동맥 단락술(1례) 및 폰탄술식(1례), 폐동맥 판 절제(또는 절개) 술후 시행한 경판륜우심실 유출로 확장술+심방 중격결손 폐쇄(3례)및 체폐동맥 단락술의 추가 등이 이차수술 또는 완전 교정술로서 일차 고식술 후 3 일에서 58개월 사이에 시행되었다. 11례의 \ulcorner아에서 술후 1개월에서 66개월 사이에 삼첨판륜직경의 Z-치가 추적되었으며, 우심실 유출로 경판륜 확장술을 시행한 8례 중 5례에서, 폐동맥판 절제(절개)술을 시행한 3례 중 1례에서 Z-치의 증가가 관찰되었다. 요약하여, 심실중격이 온전환 폐동맥 폐쇄증의 치료 전략은 우심실강의 크기와 관상동맥의 이상 유무를 고려하여 수립하는 것이 치료성적을 개선하는 최선 책이며 이때 삼첨판륜의 Z-치가 우심실강의 크기를 평가하는 비교적 신빙성 있는 지표로 사용될 수 있다고 사료된다.여도 이익고착화 현상은 존재하는 것으로 해석된다.늑막유착이 있는 환자에서 각각 18.0%와 6.0%로 늑막유착이 발견되지 않았던 환자에서의 5.1%와 1.7%에 비하여 많은 분포를 보였다. 기관지 확장증 2명(4.0%)에서 늑막유착 박 리 도중 발생한 출혈로 인하여, 개흉술로 전환하였다. 늑막유착이 있는 환자에서의 비디오 흉부수술은 수술 시간, 흉관거치기간, 재원일수등의 증가를 가져올 수 있으며, 합병증의 빈도가 높았으나, 비디오 흉부수술의 기타 장점을 고려하여 볼 때 문제점은 되지 않을 것으로 사려된다. 또한 수술 중 발견되는 예상치 못한 늑막유착 환자에서도 비디오 흉부수술의 시\ulcorner는 필요하리라 생각된다.성산소 방어효소계의 활성 또한 증가됨으로써 심근손상 의 정도가 약화되었을 가능성을 추정할 수 있으며 이러한 활성산소 방어효소의 활성증가는효소단백의 광합성 증가에 의한 것으로 여겨진다.pathy가 각각 1예씩 있었다. 본 저자들은 비디오 흥강경을 이용한 종격동 종양의 제거를 비교적 안전하게 하였으며 입원기간도 짧 고 수술과 관련된 이병율 및 사망율도 적어 환자를 적절히 선택함으로서 비디오 흥강경수술이 종격동종 괴 절제시 에 좋은 치료방법이라고 사료된다.지수가 유의한 증가를 보였는데 이는 수술 \ulcorner 동반된 폐동맥 성형술등의 영향이 있었음을 감안하여야 할 것으로 생각되었다. 한편 수술전 폐동맥 크기에 대한 지표로서 폐동맥 지수(PAI)와 McGoon 비(MGR)와는 다음과 같은 유의한 상관관계가 있 음을 알 수 있었다 상관식 : PAI : MGRxl18.0-12.4. 결론적으로 양방향성 상대정맥-폐동맥 단락술이 동맥혈내 산소포화도는 증가시키나 폐동맥 지수는 단기간의 본 연구에서는 증가하지 않는 것으로 나타났다. 향후 박동성 양방향성 상대정맥-폐동맥
