This clinical case reports the effect of Chilgi-tang, a kind of traditional Korean herbal medicine, on $3^{rd}$ degree AV block patients also known as complete heart block. Complete heart block caused by degeneration of electrical conduction system of heart may result in weakness, dizziness, syncope, etc. Two clinical cases reported herein are diagnosed as $3^{rd}$ degree AV block caused by psychological stress with chief complaints of syncope and dyspnea respectively. The chief complains of cases cured remarkably after Chilgi-tang medication. In one case, $3^{rd}$ degree AV block was disappeared. In conclusion, we suggest that Chilgi-tang can be a potential treatment for complete heart block due to psychological stress.

Introduction: This study reports the effect of herbal medicine (Samulanshin-tang-gamibang) and acupuncture on complete atrioventricular (AV) block. Case presentation: A 63-year-old female with complete AV block was experiencing dyspnea, palpitation, dizziness, headache, bradycardia, and insomnia, and she was treated with Samulanshin-tang-gamibang and acupuncture for 12 days. To evaluate the treatment, a numeric rating scale (NRS) and the New York Heart Association (NYHA) functional classification was used. The patient's NRS scores decreased from 6 to 2 for dyspnea and palpitation and from 5 to 1 for dizziness and headache. Her NYHA Class improved from Class II to Class I. No side effects were observed during treatment. Conclusion: This study suggests that herbal medicine and acupuncture may be effective in relieving symptoms caused by complete AV block. However, the long-term effects of the treatment were not observed, and so further studies are still needed.

Univentricular heart is a rare congenital cardiac anomaly in which the atrial chambers are connected to only one ventricular chamber and it consists of a diverse group of cardiac malformation characterized by both AV valves or a common AV valve opening into the same ventricle, or the presence of only a solitary AV valve. In spite of recent development in cardiac surgery, corrective operations for univentricular heart still have high mortality and complication rate. Twenty eight patients underwent corrective operation for univentricular heart at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital from February 1979 to July 1986. Of the 28 patients, 7 patients were operated on by ventricular septation and 21 patients by modified Fontan operation. Of the 28 patients, 19 patients were male and 9 patients female and ages ranged from 5 months to 18 years old with the average age of 7.3 years. There were 2 mortalities in 7 patients operated on by septation with the mortality rate of 28.6% and 5 complications, 3 complete AV block, 1 low cardiac output and 1 arrhythmia. All survived patients are being followed up without specific problem till now. There were 10 mortalities in 21 patients operated on by modified Fontan operation with the mortality rate of 47.6% and 10 complications, 2 low cardiac output, 2 respiratory failure necessitating tracheostomy, 2 persistent cyanosis, 2 arrhythmia, 1 missing of left AV valve in situs inversus patient due to misdiagnosis and one rupture of closed right AV valve. Incremental risk factors for operative mortality are young age less than 5 years old, anomalous pulmonary and systemic venous drainage and atrial septation procedure. In 11 survived patients, 9 patients show good follow-up results but one patient complains of persistent cyanosis and another one patient is suffered from CHF. In our series, results of corrective operation for univentricular heart shows continuing improvement but still high mortality and complication rate. So there must be continuing improvement in surgical result by selection of patient, by adequate decision making for timing and method of operation and by improving operative methods.

We analysed 60 consecutive patients who got Senning operation for transposition of the great arteries [TGA] with or without ventricular septal defects [VSD]. There were 41 simple TGA [group I] and 19 TGA with VSD [Group II], the operative mortality was 20 % [in group I 4.9 %, group II 52.6 %]. Among the survivors [n=48], the mean follow-up period was 7 years [range, 1 year to 13.5 years] and the actuarial survival rate at 13 years were 95 % in group I and 42 % in group II. Preoperative high left ventricular pressure and high pulmonary arterial pressure affected the surviving [p<0.01]. There occurred various type of arrhythmia like junctional rhythm, first degree atrioventricular [AV] block, sick sinus syndrome and complete AV block, and we inserted 2 permanent pacemakers for these patients. The incidence of arrhythmia were 28.2 % [11/39] in group I and 55.6 % [5/9] in group II, and the actuarial freedom from arrhythmia at 13 years after operation was 66 % [71 % in group I, 44 % in group II]. Increased aortic cross clamping time had affected the development of arrhythmia [p<0.05] which meant the complexity of the operation. The total incidence of left ventricular outflow tract obstruction [LVOTO] was 31.3 % [15/48], but only 3 patients [6.25 %] showed the significant gradient requiring reoperation. The pulmonary venous pathway obstruction [PVO] were found in 3 patients, all in group I, and among them only one required the reoperation. The estimated freedom from PVO was 89 % at 13 years [87 % in group I, 100 % in group II], but we couldn`t find any significant systemic venous obstruction in our series. There occurred 27.1 % [13/48] mild degree tricuspid valve regurgitation without necessary surgical correction. We experienced 14.6 % [7/48] reoperation rate: 3 residual VSD, 3 LVOTO, 1 PVO, 3 atrial baffle leakage. For this high incidence of complication rate after Senning operation and high mortality in TGA with VSD, We do not use this kind of surgical modality any more and do the Jatene operation for all the TGA patients since several years ago.

Background and Objectives: Cardiac resynchronization therapy (CRT) is an effective treatment for heart failure. However, in pediatric and congenital heart disease (CHD) patients, current adult indications cannot be directly applied because of heterogeneity in anatomy and diagnosis. Therefore, CRT responses and clinical outcomes in these patients were investigated to derive possible candidates for CRT. Methods: This study retrospectively analyzed 16 pediatric and CHD patients who underwent CRT implantation at a single center in early (0.7±0.2 year) and late (4.7±0.3 years) follow-up period after CRT. Results: The median age at CRT implantation was 2.5 (0.3-37.2) years, and median follow-up duration was 6.3 (0.1-13.6) years. Thirteen had non-transvenous CRT. Two had congenital complete atrioventricular (AV) block with previous right ventricular pacing, 5 had dilated cardiomyopathy (DCM) with left bundle branch block, and 9 had CHD. The mean ejection fraction of the systemic ventricle increased from 28.1±10.0% to 44.3±21.0% (p=0.003) in early and 51.8±16.3% (p=0.012) in late outcome. The mean functional class improved from 3.1±0.9 to 1.8±1.1 after CRT (p=0.003). Twelve patients (75%) showed improvement in ventricular function or functional class after CRT. Proportion of responders differed between patients without CHD (2/2 patients with complete AV block and 5/5 with DCM, 100%) and those with CHD (5/9, 56%), although statistical significance was not reached (p=0.088). Conclusions: CRT improved ventricular function and functional status according to the underlying condition in pediatric and CHD patients. However, further large and longer-term studies are needed to establish the guideline for the patient selection of CRT in these patients.

A 42 year old male was operated with aortic root abscess and pseudoaneurysm. Aortic valve vegetations which measured $8\times5$ cm and root abscess were removed and debrided. We reconstructed root and noncoronary sinus with autopericardium. Antibiotics were administered for 4 weeks. In general, Aortic root abscess recurs frequently and mortality is high. It is usually requires early surgical eradication with antibiotics medication.

Transposition of great arteries is relatively common cyanotic heart disease excluding TOF and is divided to two groups: complete TGA and congenitally corrected TGA. We experienced operations in 3 cases of TGA, the 1st case was 12 year-old male: TGA[SDD] + VSD+PS and treated with Rastelli`s operation, but expired due to low cardiac output syndrome postoperatively. The 2nd case,13 year-old male was also TGA[SDD]+VSD+PS and treated with Rastelli`s operation with good operative result. The 3rd case was 18-year old male: congenitally corrected TGA[SLL]+VSD+ PA+ASD and operation was done according to the met. hod reported by Danielson et al in 1980. Post-operative AV block led to implantation of permanent epicardial pacemaker with good result.

The results of conventional operative resection of diffuse subaortic stenosis[tunnel subaortic stenosis] have been less than satisfactory. We have performed modified Konno operation to enlarge the outflow tract of both ventricle with a patch in three patients with diffuse tunnel subaortic stenosis in the department of Thoracic and Cardiovascular Surgery, Seoul National University Children`s Hospital. Preoperative left ventricular aortic pressure gradients were 135 mmHg, 50 mmHg, 80 mmHg respectively in these patients. After right ventriculotomy, the septotomy was done and extended beyond the limit of the stenosis and fibrous and/or muscular tissue was removed from each edge of septal incision. After adequate widening of the tunnel subaortic stenosis with various patches, right ventricle was closed primarily or with prosthetic patches successfully. One patient who was diagnosed as complete atrioventricular septal defect had complete AV block preoperatively and was implanted permanent pacemaker, and others who were sinus rhythm preoperatively have no serious postoperative rhythm disturbance. One patient developed mild postoperative aortic insufficiency and one who had preoperative aortic insufficiency has still same grade of aortic insufficiency after operation. All had good postoperative hemodynamics without any postoperative residual pressure gradient.

From Oct. 1983 to Dec. 1991, 135 cases of atrial septal defect which were operated at the department of Thoracic and Cardiovascualr Surgery, Chonnam National University Hospital, were analysed retrospectively. They were 23.7% of all congenital heart diseases operated in the same period. Among the 135 cases, 62 cases were male and 73 cases were female. Their ages were ranged from 2 to 54 years and the mean was 18 years old. Main symptoms at admission were exertional dyspnea[70.37%], frequent URI[49.12%] and palpitation[32.59%], but 12 cases[8.88%] were asymptomatic. Electrocardiographic findings wer regular sinus rhythm in 96.99%, RVH in 64.66%, incomplete RBBB in 27.06%, complete RBBB in 42.10%, and first degree AV block in 9.02% All 135 cases were operated under the direct vision with cardiopulmonary bypass. Anatomically, most frequent type was fossa ovalis defect with complete septal rim[78.52%]. 117 of 135 ASD patients were repaired with pathch closure[86.66%] and 14 patients were repaired with direct closure[10.37%] and 4 patients in mutiple ASD were repaired with patch and direct closure[2.96%]. Postoperative complications were occured in 21 cases[15.56%], and they were wound infection, pleural effusion, postoperative bleeding, urinary tract infection, and heart failure mainly. One case died due to epidural hematoma and operative mortality was 0.74%.
