Primary intracardiac repair of tetralogy of Fallot with low mortality and early good results, has been accomplished in recent years. But palliative procedures have been reserved for those hypoplastic pulmonary arteries, a hypoplastic left ventricle or anomalies of the coronary artery would make total correction difficult. And the Blalock-Taussig shunt operation is recognized as a standard and popular palliative procedure. I undertook a retrospective determination of the effect of the Blalock-Taussig shunt operation on the development of the main pulmonary artery and the right and left pulmonary arteries. Between January, 1980, and April, 1987, at the Severance Hospital, 16 patients were studied by cardiac catheterization and angiocardiography, before undergoing Blalock-Taussig shunting procedures for the palliation of severe symptoms of tetralogy of Fallot, and some time later, usually prior to a second procedure. The mean interval between catheterizations was 22.25 months. Patients with tetralogy of Fallot and pulmonary atresia or with an occluded shunt were not included. The primary and secondary angiograms of each patient were reviewed, and measurements of the diameter of the main pulmonary artery, the right and left pulmonary arteries, and the descending thoracic aorta were taken. The results are as follows; 1. The hematocrit decreased from 56.39% to 50.34%[p< 0.05], and the arterial oxygen saturation increased from 62.00 % to 81.31 %[p< 0.001] following shunt procedures 2. The ratio of the diameter of the right pulmonary artery plus the left pulmonary artery to the diameter of the descending thoracic aorta increased 1.30 k 0.28 times [p< 0.01]; but the ratio of the diameter of the main pulmonary artery to the diameter of the descending thoracic aorta increased 1.10 * 0.33 times, which was not. significant[p< 0.05]. 3. The interval between shunting and second catheterization was not related to the magnitude of change in the pulmonary arteries[r=0.141, p >0.05]. 4. The changes in the ratio of the diameter of the right pulmonary artery plus the diameter of the left pulmonary artery to the diameter of the descending thoracic aorta was inversely related to the initial ratio[r=0.757, p >0.001], but the change in the ratio of the diameter of the main pulmonary artery to the descending thoracic aorta was not related[r=0.059, p >0.05]. 5. There were no differences in enlargement of the pulmonary artery on the side of the shunt [ipsilateral] versus enlargement on the opposite side [p >0.05], nor according to the size of the shunt[p >0.05]. In conclusion, this study suggests that the Blalock-Taussig shunt is effective for the development of the right and left pulmonary arteries but not effective for the main pulmonary artery.

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.

Objective : Transradial angiography has become popular among many cardiologists as a diagnostic and therapeutic tool. However, transradial cerebral angiography is not utilized to the same extent. The purpose of this study is to present our experience regarding the usefulness of transradial cerebral angiography, especially in elderly patients. Methods : Between May 2011 and February 2012, a total of 126 cerebral angiographies were performed via a transradial approach in a single center. Of them, only 47 patients were over 60 years old. In our institution, we shifted the initial access from the right femoral artery to the right radial artery in all patients requiring cerebral angiography in 2011. We did not attempt radial access in 40 cases for variable reasons. Results : The procedural success rate was 92.2%. We have four failures of transradial angiography; two because of loop formations of the radial and brachial artery and two due to multiple puncture failures. All supra-aortic vessels were successfully catheterized. However, the selective catheterization rates of the left side distal vessels were lower, as success rates were 89.7% for the right internal carotid artery and 75% for the left internal carotid artery. Procedure-related vascular complications, such as puncture site hematoma, hand ischemia, pseudoaneurysm, arteriovenous fistula and arterial dissection were not observed in our series. However, intraprocedural thrombosis developed in one patient, which was resolved completely by intraarterial thrombolytic agents. Conclusion : With advancing patient's age, we believe that transradial cerebral angiography is a useful tool to decrease patient's discomfort and more effectively manage the vessel tortuosity.

Background: Recently, it has been demonstrated that endothelin(ET) and endothelin related peptides are present in the blood and plasma ET levels are increased after operation. But the causes of increasing plasma ET levels are not clearly understood. This current study was to investigate the relationship between postoperative pain and endothelin. Methods: Thirty adult patients, scheduled for upper abdominal operation under general anesthesia, were included. After operation, epidural catheterization was done for postoperative analgesia. Before induction, on complained of pain and 1 hour after analgesics administration, blood samples were obtained to measure plasma ET levels. Plasma ET concentration was determined by radioimmunoassay. Pain score was measured by visual analogue score(VAS). Mean arterial pressure(MAP) and heart rate(HR) were also recorded every sampling time. Results: There were no significant changes in plasma ET levels at the time before induction versus at the time of the pain complaints and at 1 hour after analgesic administration. Pain score was significantly reduced after epidural analgesia. There was no significant correlations between pain score and plasma ET levels. There were no significant correlation between plasma ET levels and either MAP or HR. Conclusions: These results indicate that there is lack of relationship between postoperative pain and endothelin.

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.

A clinical study was performed on 69 cases of isolated PDA surgically treated at the Department of Thoracic and Cardiovascular surgery of Kyung-Hee University Hospital from Mar. 1986 to Feb. 1994. Retrospective clinical analysis of these patients were as follows: 1.23 males and 46 females ranged in age from 16 days to 49 years. [mean 8.69yrs.,sex ratio M:F=1:2 2. Chief complaints were frequent URI in 44%, dyspnea on exertion in 16%,palpitation in 8%, easy fatigability in 6%, and no subjective symptoms in 26%. 3. On auscultation, typical continuous machinery murmur heard in 84%, and systolic murmur in 16% on Lt 2nd or 3rd intercostal space. 4. Simple chest x- ray showed increased pulmonary vascularity in 67%, cardiomegaly in 61%,and within normal limit in 16%. 5. EKG findings were LVH in 42%, biventricular hypertrophy in 17%, RVH in 3%, and within normal limit in 38%. 6. Echocardiogram was performed from all patient, and direct visualization of ductus in 93% 7. Cardiac catheterization was performed in 39 patients.

Sixty-nine patients with various types of cyanotic congenital heart disease underwent systemic-pulmonary artery shunts with a microporous polytetrafluoroethylene [PTFE] prosthesis between 1979 and 1985. Their ages ranged from 2 months to 39 years [mean$\pm$SD: 5.2$\pm$7.4, median: 3.3 years]. Diagnosis included the following: Tetralogy of Fallot, 45: Double outlet right or left ventricle, 11: Single ventricle, .5: Transposition of great vessels, 4: Tricuspid atresia, 3 and Pulmonary atresia with intact ventricular septum, 1. Forty-eight patients had subclavian-pulmonary artery anastomosis, 12 patients aorta-right pulmonary artery anastomosis, 6 patients aorta-main pulmonary artery anastomosis, and 3 patients descending aorta-pulmonary artery anastomosis. The PTEE graft of 3 mm in diameter was used in 1, 4 mm in 29, 5 mm in 35 and 6 mm in 4 patients. Ten patients were died within 30 days after operation [mortality rate: 14.5%]. Among them, 6 patients were operated in urgency due to cardiac arrest or severe anoxic spell after cardiac catheterization, and so surgical mortality of elective operation is 9.5%. The 59 survivors showed improvement of the arterial oxygen saturation [65.4% - 9.8%] and hemoglobin [18.8 gm/dl - 16.0 gm/dl] values [V<0.01]. The follow up period ranged from 1 month to 67 months, [752 patient-months] and during this periods there were 4 late shunt failures after 3 months postoperatively with 4 mm graft, and 2 with 5 mm graft. The over-all patency rate of 4 mm PTFE was 85.9$\pm$9.2% [SEM] in 12 months and 40.9$\pm$22.5% in 24 months. The over-all patency rate of 5 mm PTFE was 87.5$\pm$9.6% in 12 months and 58.3$\pm$24.6% in 36 months. The lowest systolic pressure in death group was 64.9$\pm$15.0 mmHg and in survival group, 86.4$\pm$12.1 mmHg [P<0.001]. We think that the PTFE graft is useful in palliative shunt operation, but the effectiveness of the 4 mm PTFE graft may be limited. The blood pressure also may play an important role in patency of Prosthesis.
