Automatic junctional tachycardia is one of common atrial arrhythmia after open heart surgery which is often refractory to antiarrhythmic agents. We have experienced refractory automatic junctional tachycardia in two patients. In the first, it occured after cryosurgery for AV nodal reentry tachycardia and simultaneous dissection of a posterior septal bypass tract. In the second, it complicated the postoperative course of a patient who received intracardiac repair for double outlet right ventricle, ventricular septal defect, and pulmonary stenosis. Conventional therapy with atrial pacing, verapamil, digoxin, and electrical cardioversion were ineffective. Therefore, amiodarone was administered intravenously and it controlled automatic junctional tachycardia. The need for accurate and rapid diagnosis of this condition along with results of treatment are discussed.

Left main bronchus compression occasionally occurs in patients with cardiac disease. A 19-month-old female patient weighing 6.7 kg was admitted for recurrent pneumonia and desaturation. S he had an atrial septal defect (AS D) with a right aortic arch. Her left main bronchus had been compressed between the enlarged right pulmonary artery (RPA) and the descending thoracic aorta for 14 months. We conducted ASD closure and RPA anterior translocation via sternotomy. The left main bronchus compression was relieved despite the medium-term duration of compression.

Clinical analysis was performed of 89 secundum type atrial septal defect patients operated on during the period from July, 15th, 1981 to March, 1987 in the Thoracic and Cardiovascular Surgery Department of Pusan National University Hospital. Secundum type ASD was 2`I.0% among all of congenital heart diseases operated in the same period. The age distribution of patients ranged from 3 to 41 years and sex ratio, male to female was 1.23 to 1.0. Common symptoms were exertional dyspnea 64.0%, frequent upper respiratory infection 43.8%, cyanosis 10.1% and fatigue 7.9%. The mean value of cardiac catheterization data of the group of ASD combined with another cardiovascular anomalies was compared with that of only ASD group. The amount of shunt showed not statistically significant difference between two groups [P>0.05] but pulmonary arterial pressure and pulmonary vascular resistance of combined group was significantly higher than that of only ASD group [P<0.02, P<0.01]. The difference of mean hemodynamic data between the age group below 20 years and above 21 years was not statistically significant [P>0.05]. All cases were operated under cardiopulmonary bypass. Among these 51 were closed directly and 38 were applied Dacron patch. Two most common associated cardiac anomalies were pulmonary stenosis [8 cases, 9.0%] and VSD [8 cases, 9.0%]. The most frequent postoperative complication was wound infection, One patient died of low cardiac output on 10th postoperative day and the overall operative mortality was 1.1%

An eight-day-old neonate was diagnosed with dextro-transposition of the great arteries, atrial septal defect, patent ductus arteriosus, and a single sinus origin of the coronary arteries. The single coronary artery originated from the left sinus (sinus 2), had a proximal left circumflex arterial branch, and passed anteriorly to the right side of the aorta, further branching into the right coronary and left anterior descending arteries. We successfully performed an arterial switch operation and coronary transfer by tube graft reconstruction with autologous aortic tissue to treat the dextro-transposition of the great arteries and atrial septal defect with a single-sinus origin of the coronary arteries.

목 적 : 본 연구는 경피적 심방중격결손 폐쇄술 시 TTE 및 TEE를 이용하여 측정한 결손의 크기와 BOD과의 차이를 분석하고 이에 영향을 줄 수 있는 혈역학적 및 해부학적인 요인에 대해 알아보고자 하였다. 방 법 : 2003년 5월부터 2004년 6월까지 본원에서 연세대학교 심장혈관병원 소아심장과에서 이차공 심방중격결손 진단 하에 경피적폐쇄술을 시행받은 78명의 환자(남자 20명, 여자 58명, 평균연령 $18{\pm}17.4$세)를 대상으로 하였다. 각 환자에서 TTE와 TEE를 시행하여 결손의 크기 및 주변구조들(대동맥, 상대정맥, 하대정맥, 승모판연, 심방후벽)과의 거리를 측정하였고 시술 시 TEE 유도 하에 BOD를 측정하여 상관 관계와 관련 요인을 분석하였다. 결 과 : BOD와 TTE로 측정한 직경의 차이는 흉골연 단축상에서 $4.8{\pm}3.6mm$, 흉골하 장축상에서는 $5.4{\pm}3.2mm$였고 BOD와 TEE상 직경과의 차이는 단축상에서 $3.6{\pm}2.2mm$, 장축상에서 $4.2{\pm}3.1mm$였다. 선형회귀분석을 통한 BOD와 TTE상 직경의 회귀방정식은 흉골연 단축상에서 Y=1.12X+3.86(R2=0.82, P< 0.01), 흉골하 장축상 (또는 심첨 4방상)에서 Y=1.01X+5.32(R2= 0.83, P<0.01)(Fig. 4), BOD와 TEE상 직경의 회귀방정식은 단축상에서 Y=1.02X+3.88(R2=0.89, P<0.01), 장축상에서 Y=1.05X+3.60(R2=0.83, P<0.01)였다. BOD와 TTE 및 TEE 상의 결손의 직경의 차이는 환자의 나이가 많을수록, 결손과 심방 후벽까지의 길이가 길수록, 승모판연까지의 거리가 길수록, TTE상 결손의 직경 및 심방중격의 길이가 길수록 통계학적으로 의미 있게 증가하였다(P<0.05). 결 론 : 심방중격결손의 BOD는 TTE 및 TEE상의 직경의 크기로 어느 정도 예측이 가능하며 심초음파상 결손의 크기 및 주변 구조들과의 거리와 결손의 위치에 따라 BOD가 더 크게 측정될 것으로 예상할 수 있어 경피적 기구 폐쇄가 가능한 환자의 선정, 시술에 따른 어려움의 예측과 시술 시 적정성의 판단에 도움이 될 수 있을 것으로 생각된다.

The anomalous pulmonary venous return of the entire left lung was an extremely rare congenital anomaly. The reported surgical experience with correction of this disorder was limited. The 3-year-old female patient underwent an operation upon the unilateral total anomalous pulmonary venous return from the left lung, in which the left superior pulmonary vein drained into innominate vein and the left inferior pulmonary vein into the coronary sinus, in Yeungnam University Hospital. The symptoms were nonspecific except frequent upper respiratory infection. Cyanosis was not seen. On auscultatory findings, a grade 2/6 systolic ejection murmur was audible over left second intercostal space of left sternal border and second heart sound had an increased pulmonary component which was widely splitted. The electrocardiogram demonstrated a right ventricular hypertrophy and right axis deviation and chest X-ray showed slightly increased pulmonary vascularity and bulged pulmonary conus. The echocardiogram demonstrated increased right atrial, ventricular, and pulmonary arterial dimension, and also secundum atrial septal defect and enlarged coronary sinus. The cardiac catheterization confirmed the left-to-right with a Qp/Qs of 2.0: 1 and oxygen step-up was seen in pulmonary artery, right ventricle, right atrium, and left innominate vein, and the catheter was not been introduced into the left pulmonary vein. A median sternotomy incision was done. Left superior pulmonary vein was drained to the innominate vein through anomalous vertical vein and the left inferior pulmonary vein drained to right atrium through the coronary sinus. The diversion of the left inferior pulmonary vein to posterior wall of left atrium was done after division in the proximity of coronary sinus. The anomalous vertical vein was diverted to base of left atrial auricle and then a atrial septal defect was sutured directly. The postoperative course was uneventful and she was discharged on the eleventh postoperative day. In the postoperative follow-up-2 months, she has been well without specific problems.

One hundred cases of open heart surgery were done at this Department in 1977. There were 65 congenital anomaly and 35 acquired diseases. Out of 65 cases of congenital malformation 35 acyanotic and 30 cyanotic cases were found. Fifteen cases of ventricular septal defect and 29 tetralogy of Fallot were noted eight patients expired out of 65 congenital anomaly [12.3%] , 4 out of 35 acyanotic [11. 4%] and 4 among 30 cyanotic anomaly[13.3%]. Among 35 cases of acquired heart disease 3 atrial myxoma [2 left and one right] and 32 valvular lesions were noted. In two cases open mitral commissurotomy, and in 30 valve replacement were done. Twenty-two single valve and 8 double valve replacement were done. Seven patients expired out of 30 patients [23.3%]. Among 22 single valve replacement cases 2 and among 8 double valve 5 died. ~ In eighteen mitral valve replacement cases 2 deaths occurred. One mitral insufficiency patient who expired suffered from severe pulmonary` hypertension [PA=120/67mmHg], tricuspid insufficiency and a large ventricular septal defect. The patient underwent mitral valve replacement, tricuspid annuloplasty and patch closure of ventricular septal defect. Over all mortality rate for 100 open heart surgery cases was 15%. Since 1977 open heart surgery cases were done routinely in this institution and cases are increasing rapidly. With present rapid improvement of economical status and introduction of medical insurance system, open heart surgery will be firmly established in Korea in the very near future.

From January 1978 to December 1992, 59 patients of double chambered right ventricle were repaired. Surgical correction consisted of closure of the ventricular septal defect and resection of anomalous muscle bundles through right ventriculotomy [Group I ; 34 patients] or right atriotomy [Group II ; 25 patients]. Between these two groups, there was no difference in the operation time and the postoperative results. All patients survived. In group I, hemodynamically significant residual ventricular septal defect was found in three and reoperations were necessary. In one patient, subacute bacterial endocarditis developed postoperatively. In group II, complete atrioventricular block developed in one and mediastinitis in two. Follow-up period was from 2 to 75 months [mean 17.1 months]. There was no late death. All patients have remained in sinus rhythm except one patient. Careful evaluation of echocardiographic and catheterization data preoperatively and careful examination of the anatomy intraoperatively are necessary so that double chambered right ventricle should not be overlooked, because most ventricular septal defects are now closed through the right atrium. Repair of double chambered right ventricle is also easily performed through the atrial approach. Transatrial repair should be considered as an alternative to the transventricular approach in patients with this congenital heart defect. Successful surgical correction of double chambered right ventricle is expected with excellent long term results.

To clarify the apparent hypoplasia of the descending aorta in infants with atrioventricular septal defect[AVSD] patients, we reviewed the catheterization data and angiograms of 34 consecutive patients with AVSD less than 1 year of age who underwent repair at our institution since 1985. We compared them to 10 patients with Atrial Septal Defect[ASD] and 10 patients with Ventricular Septal Defect[VSD] who were matched for age, size and Qp/Qs. The Descending Aorta Index [DAI] of the AVSD group was not different from the VSD or ASD groups, [147.9$\pm$ 34.8 mm2/m2 versus 158.6$\pm$ 31.5 mm2/m2 and 153.2$\pm$ 43.1 mm2/m2].However, the Pulmonary Artery Index [PAI] of the AVSD group was significantly larger than the other groups [684.3$\pm$ 170.7 mm2/m2 versus 454.1$\pm$ 109.1 mm2/m2 and 534.9$\pm$ 148.4 mm2/m2][p<0.05], as was the ratio of PAI/DAI in the AVSD group [4.99$\pm$ 1.77 versus 2.89$\pm$ 0.81 and 3.6$\pm$ 0.92][p<0.05]. Despite similar Qp/Qs ratios, both the mean PA pressure and the Rp/Rs in the AVSD group was higher than the VSD and ASD groups: 43.1$\pm$ 15.6 mmHg versus 29$\pm$ 11.6 mmHg and 24$\pm$ 18.1 mmHg [p<0.05], and 0.27$\pm$ 0.22 versus 0.14$\pm$ 0.03 and 0.11$\pm$ 0.05 [p<0.05] respectively. The apparent hypoplasia of the descending aorta in infants with AVSD is an illusion created by the abnormally large pulmonary arteries, which are significantly larger than in patients with ASDs or VSDs.
