Despite low mortality and excellent long-term results after repair of Tetralogy of Fallot, certain associated anomaly such as single pulmonary artery continues to be told to have a high operative mortality and morbidity, and there is still some debate on appropriate surgical intervention. During the 4 year period from 1981 to 1984, surgical repair was performed on 5 patients with tetralogy of Fallot and congenital [4 cases] or acquired [1 case] absence of left pulmonary artery. Previous left pneumonectomy had been performed in the patient with acquired absence of a pulmonary artery. Transannular patch or RVOT patch alone with or without pulmonic valvotomy was used with some modifications to reduce pulmonic insufficiency in individual patient. In contrast with previous reports, all patients survived operation and have exhibited marked symptomatic improvement without pulmonic valve insertion nor valved conduit.

The term corrected transposition of great arteries [hereafter referred to as corrected TGA] of the heart in which there is both a discordant atrio-ventricular relationship and transposition of the great vessels. Usually situs solitus is present, while the ventricles are inverted showing an l -loop. The great vessels are transposed and in the l-position so that the pulmonary artery arises from the right-sided morphological left ventricle and the anteriorly l- transposed aorta arises from the left-sided morphological right ventricle yielding an SLL pattern. In the majority of cases, associated lesions are common. The most frequent are ventricular septal defect, obstruction to the pulmonary outflow tract, tricuspid valve incompetence and atrio-ventricular conduction abnormalities. In the rare cases, no associated conditions are present and hemodynamic pathways are normal. In the report, we present one case of a 20 year-old male having corrected TGA associated with severe tricuspid valve incompetence, was corrected by tricuspid valve replacement, directly developed a supra-ventricular tachycardia but was controlled by calcium-entry blocker, verapamil, successfully.

배경: 폐동맥유출로 재건 후의 폐동맥판막 폐쇄부전 또는 협착은 초기에는 증상을 일으키는 경우가 적지만 시간이 경과함에 따라 심한 증상을 동반하는 우심비대 및 우심부전, 부정맥 등을 초래할 수 있다. 본 연구에서는 이런 경우에 조직판막을 이용하여 폐동맥판 대치술을 시행한 16례의 환자에 대한 임상적 단기성적에 대해 알아보고자 하였다. 대상 및 방법: 1999년 9월부터 2002년 2월 사이에 폐동맥판 대치술을 시행한 16명의 환자를 대상으로 하였고(남아 9명, 여아 7명), 진단은 팔로씨사징(n=11)과 그 외 폐동맥유출로 협착을 동반한 선천성 심기형(n=5)이었다. 판막은 Carpentier-Edwards PERIMOUNT Pericardial BioprOSTHESES와 Hancock porcine valves를 사용하였는데 조직판막 외륜의 후방 3분의 2를 환자의 폐동맥판륜 위치에 삽입하고 전방 3분의 1을 우심낭 첩포로 덮었다. 술전 13명에서 중등도 이상의 폐동맥판막 폐쇄부전이 존재하였고 3명에서는 중증 폐동맥판막 협착이 있었다. 12명에서는 삼첨판막 폐쇄부전이 존재하였다. 결과: 추적관찰은 모든 환아에서 이루어졌으며 추적관찰기간은 15.8$\pm$8.5개월이었다. 수술 관련 사망은 없었다. 술후 심흉곽비는 66.0 $\pm$ 6.5%에서 57.3 $\pm$ 4.5%로 감소하였고(n=16, p=0.001), 가장 최근 추적관찰에서 NYHA 기능분류는 전례에서 I 등급이었다(n=16, p=0.06). 술후 폐동맥판막 폐쇄부전은 모두에서 경도이하로만 남았고, 삼첨판막 폐쇄부전은 미세이하로만 남았다. 결론: 본 연구에서 우심부전을 동반하거나 혹은 그렇지 않은 경우도 잔존 폐동맥판막 폐쇄부전 또는 협착에 대해 조기에 조직판막 대치술을 시행하는 것이 심비대의 감소와 폐동맥판막 및 삼첨판막 폐쇄부전의 호전, 임상증상의 호전을 보였다는 점에서 적어도 단기 관찰 소견상 적절함을 보였다. 그러나 향후 장기 추적관찰 결과는 주의깊게 살펴보아야 할 것으로 사료되었다.

From Aug. 1984 to May 1986, 116 cases of cardiovascular surgery including 85 cases of open heart surgery were performed at Korea Veterans Hospital. There were 108 congenital anomalies and 8 acquired valvular heart diseases. Among 108 congenital malformations 92 operations were done for acyanotic group, and 16 operations for cyanotic group. Thirteen cases of open heart surgery for infants or small children under 10kg of body weight were performed, which occupied 15.3 percent of total open heart surgery done in the same period. Common congenital cardiovascular anomalies were ventricular septal defect [40.7%], patent ductus arteriosus [29.6%], tetralogy of Fallot [12.[%], atrial septal defect [11.1%], and pulmonary stenosis [1.9%] in order of frequency. Valve replacement using lonescu-Shiley or Carpentier-Edwards valve was performed for 8 cases of acquired mitral valve disease, and valve replacement using St. Jude valve was done for a case of patent ductus arteriosus with severe mitral insufficiency. There was no mortality in acyanotic congenital malformations and acquired valve lesions, and 5 cases of mortality in cyanotic congenital malformations. Overall mortality was 4.3 percent for total cases and 5.9 percent for 85 cases of open heart surgery.

Subannular aortic aneurysm is a word-wide rare disease entity occurring predominantly in young black men. In Korea, there has been no report. We report one patient, 46 years old man, who had been operated urgently because of acute aortic insufficiency and aortic valvular vegetation after antibiotics treatment of Subacute bacterial endocarditis for 6wks. At the operative field, We found the bulging aneurysmal mass between the aorta and superior vena cava above the right pulmonary artery, which has subannular communicating opening into the left ventricular cavity, beneath the anterior commissure of the bicuspid aortic valve. Pathologic findings are consistent with "portion of vascular wall with features of aneurysm.* The patients survived aortic valve replacement and patch closure of subannular aneurysm, with no symptoms at one-year postoperative follow-up.w-up.

The incidence of annuloaortic ectasia has known rare, and approximately 5-10% of aortic regurgitation. The patient was 44 years old male who complained exertional dyspnea and left anterior chest pain. He had done Lt. side 2 stage thoracoplasty for pulmonary tuberculosis about 20 years ago at Dept.of Chest surgery of National Medical Center. At that time, there was no abnormal findings in cardiovascular system. The preoperative aortic cineangiogram showed pear shaped dilatation [7.3 cm x 6.8 cm] of aortic mot with aortic valve regurgitation but left ventricular ejection function was fair. Preop. ventilatory function test showed mixed type pulmonary insufficiency. Recently, we corrected surgically, by AVR with Carpentier-Edwards Bioprosthesis [29mm] & supracoronary Woven Dacron graft [29mm x 5cm] replacement, with good clinical result for follow up 6 months.

The present study reports 41 cases of congenital and acquired heart diseases, who received open heart surgery under extracorporeal circulation [ECC] by Sarns Heart-Lung-Machine [HLM] at the Department of Thoracic and Cardiovascular Surgery, Hanyang University Hospital during the` period between July 1975 and February 1979. The priming of pump oxygenator was carried out by the hemodilution method using Hartman`s solution, whole blood, and fresh human plasma. The rate of hemodilution was in the average of 50.8 ml/kg. ECC was performed at the average perfusion flow rate of 85.0 ml/kg/min [2.43 L./ kg/2] and at moderate hypothermia. In the total cardiopulmonary bypass, arterial pressure ranged between 55 mmHg and 90 mmHg, but generally maintaining over 70 mmHg. Patient age ranged between 2 and 54 year old, in congenital heart diseases, between 2 and 28, in acquired heart diseases, between 17 and 54 Sex ratio of male to female was 20:21. The cases include a case of pulmonary valvular stenosis, 4 cases of atrial septal defect, 9 cases of ventricular septal defect, 9 cases of tetralogy of Fallot, 5 cases of pentalogy of Fallot, 3 cases of atypical multiple anomalies 7 cases of mitral stenosis or insufficiency, a case of myxoma in left atrium, and a case of ruptured aneurysm of Valsalva`s sinus. The surgical managements were 16 valvulotomy for pulmonary valvular stenosis, 2 Teflon patch graft closure and 5 simple suture closure of atrial septal defect, 16 Teflon patch graft closure and 5 simple suture closure of ventricular septal defect, 12 pericardial patch graft for infundibular stenosis of right ventricle, one anastomosis between left superior vena cava and right atrium, 2 open mitral commissurotomy, 5 mitral valve replacement using Starr-Edward`s ball valve, porcine xenograft by Hancock, by Carpentier-Edward, or Angell-Shiley, one removal of left atrial myxoma, and a repair of ruptured aneurysm of Valsalva`s sinus. Four [9.7%] out 41 cases expired postoperatively and the rest of 37 cases survived with satisfactory results. The causes of death were one coronary embolism in tetralogy of Fallot, 2 postoperative lower cardiac output in atypical multiple anomalies, and one right heart failure in large: ventricular septal defect with pulmonary hypertension.

Thirty-seven patients had undergone repair of a endocardial cushion defect between 1977 and Aug. 1983 in Seoul National University Hospital. Twenty eight had a partial defect, one intermediate defect and eight complete endocardial cushion defect. Tricuspid cleft was found in 4 cases and mitral cleft was in all p-ECD. Seven patients were of type C anatomy in c-ECD. Four patients had associated major anomalies, including three TOF in c-ECD, one coarctation in p- ECD. In p-ECD patients, the septal defect was closed with patch in all cases and the atrioventricular valvular insufficiency was corrected with MVR in 4 cases, TVR in 1 case and simple interrupted sutures in remainders. In c-ECD patients the septal defect was closed with single patch except one case. The atrioventricular valve was repaired with simple interrupted sutures except one MVR and TVR case. The operative mortality was 14.2% in p-ECD, 44.4% in c-ECD, but recent 3 years [1980-1983] mortality was 8.7% in p-ECD, 20% in c-ECD. More than grade III systolic regurgitant murmur was oted postoperatively in 4 cases of c-ECD and 3 cases of p-ECD. The operative risk factors were preoperative NYHA classification, cyanosis, Rp/Rs, systolic pressure of main pulmonary artery and the degree of regurgitation of atrioventricular valves. The causes of death were low cardiac output syndromes, pulmonary complications and arrhythmias.
