Bridging bronchus (BB) is an extremely rare tracheobronchial anomaly. This anomaly is often associated with a sling left pulmonary artery (SLPA) and is diagnosed in infancy or at autopsy. A 29-year-old female patient with previous history of pulmonary tuberculosis was admitted because of persistent fever, cough and sputum. Fiberoptic bronchoscope and chest computed tomography revealed a bridging bronchus and associated atelectasis. The right middle and lower lobe was supplied by a bronchus which originates from the left main bronchus and bridges the mediastinum. There was no anomaly of a left pulmonary artery. Right middle and lower bilobectomy was performed.

Bone cement embolism often occurs during percutaneous vertebroplasty. Bone cement pulmonary arterial embolism generally requires no treatment because of the small size and asymptomatic manifestation. Intracardiac bone cement embolisms are rare but associated with a risk of severe complications. Intracardiac bone cement embolisms are mainly removed through open heart surgery. To the best of our knowledge, only three cases of intracardiac bone cement embolisms removed with interventions have been reported. Here, we report another case of successful transcatheter retrieval of a 6-cm-long cement embolism in the right atrium after percutaneous vertebroplasty. The embolus broke in half and migrated to the right pulmonary artery intraoperatively. Using two snares and a filter retrieval device, we advanced from opposite directions. Further, we gently grasped and pulled the fragments of the right pulmonary artery and aligned them in a linear fashion directly into the sheath for uneventful removal.

Anomalous origin of right coronary artery from left sinus of valsalva is associated with sudden unexpected death, syncope, arrhythmia and myocardial ischemia. The mechanism that explains the restriction of coronary flow in the anomalous coronary artery is unclear but several surgical methods have been proposed, such as coronary artery bypass graft, coronary reimplantation, translocation of pulmonary artery, and unroofing procedure. We reported the surgical correction of the anomalous origin of right coronary artery from left sinus of valsalva between the aorta and pulmonary trunk using the unroofing procedure.

Background: TNF-$\alpha$ plays a major role in producing left ventricular dysfunction cardio-myopathy pulmonary edema and inhibits the compensatory mechanism of congestive heart failure. IL-6 is an acute reactant of immune reaction and also known to control immune reaction but its function in the myocyte was not clearly investigated. Author's performed this experiment to investigate the contents of TNF-$\alpha$ and IL-6 on the assumption that TNF-$\alpha$ and IL-6 may reside in nonfailing heart that has gone cardiac surgery and play some role in cardiac function. Material and Method : Right auricular tissues were sampled from 12 patients who had undergone total corrective surgery for both congenital and acquired heart diseases from January 1998 to June 1998 in Kosin Universcfy Gospel hospital. The quantitive analysis of TNF-$\alpha$ and IL-6 were assessed by ELISA method in right auricular tissue. Hemodynamic values about the pressure of ventricle atrium aorta pulmonary artery and cardiac index pulmonary and systemic vascular resistance and cardiac output were measured by echocardiography and cardiac catheterization and biochemical analyses of LDH & AST were done before operation. statistical analysis was by Paired Student t-test. Patients were divided into children(under 15 years olds) and adults groups and the data was compared beween two groups. Conclusion: Mild pulmonary hypertension and increased pulmonary vascular resistance were existed in both group. The contents of tissue TNF-$\alpha$ IL-6 in each group were independent of each data.

Fourty-three infants underwent intracardiac repairs within the first 12 months of life. Mean age was 7 months and mean weight was 6.7 kg. A quarter of them were below 5 kg. Overall mortality including complex anomalies was 17.9%. Thirty-four infants with a ventricular septal defect[VSD were treated. Three infants[8.8% died in the early postoperative period, but only one[3.7% of the infants without having associated lesions was dead. VSD was repaired either by the incision on the right atrium, pulmonary artery, or right ventricle. Postoperative right bundle branch block[RBBB occurrence were different according to the approach: 30.8 % in pulmonary arteriotomy, 37.5 % in atriotomy, and 42.8 % in ventriculotomy. Surgically induced heart block did not occur in any patient, but 10 had temporary arrhythmia, and 11 patients were under temporary pacing from one day to 4 days without any persisting rhythm disturbances. Pulmonary hypertension was present in 29 infants preoperatively, and seven of them developed postoperative elevation of the pressure. Infants complicated with pulmonary hypertensive crisis were managed successfully. Inotropics were necessary in 55.8 % of the infants and vasodilators in 37.2 %. Platelet transfusion were needed in 10 cases who required 272 ml in average, but one who died from sepsis consumed 5,370cc of platelets. And we discuss complications and causes of deaths.

Pulmonary arteriovenous fistulas(PAVFs) is a rare disorder that occurs in two to three children per 100,000 population. It is presented as absence of intervening capillary beds between the pulmonary artery and vein with resultant persistent right to left shunt. Other causes include trauma, liver cirrhosis, malignancy and schistosomiasis. It is mostly asymptomatic, but it may present with respiratory difficulty, cyanosis, clubbed fingers induced by right to left shunt or hemoptysis, polycythemia and epistaxis. Major complications, such as brain abscess, brain embolism, paradoxical embolism and subacute infective endocarditis can be devastating, so therapeutic intervention is recommended in all patients. However, removal of low-resistance fistulas can aggrevate pulmonary hypertension, so detection of increased pulmonary pressure is important. We report two patients : One a 42 year-old male with PAVFs treated with coil embolization, and a 42 year-old female who was treated with anticoagulants due to pulmonary hypertension.

From February 1988 to December 1990, 42 patients underwent so called REV operation for pulmonary stenosis or atresia with or without anomalies of ventriculoarterial connection and truncus arteriosus. The principles of operative technique are mobilization of pulmonary arterial tree beyond the pericardial reflection, transection of pulmonary trunk between the pulmonary ventricle and pulmonary artery, suture of distal pulmonary arterial stump to the upper margin of Pulmonary ventriculotomy site with absorbable suture, and anterior patch with 0.625% glutaraldehyde fixed autologous pericardium with monocusp inside it. Age at operation ranged 3-156months [mean 41.8 month] with twelve of whom infants. Operative indications were pulmonary atresia, with ventricular septal defect[16], and pulmonary stenosis with double outlet right ventricle[8], with ventricular septal defect[16], with double outlet right ventricle[8], with complete transposition of the great arteries[8], with corrected transposition of the great arteries[6], with Fallot`s tetralogy[3], and truncus arteriosus[1]. There were six hospital deaths[14%] and no late death. Twenty-four of 36 survivals were followed up more than 12 months with good clinical results. Postoperative angiocardiogram was performed in fifteen patients. Hemodynamically, two patents had residual pressure gradients along the pulmonary outflow tract, one patient showed severe pulmonary regurgitation; morphologically, there were six significant stenosis of left pulmonary arterial tree, two of whom showed significant pressure gradients. Our present experience with REV operation suggests that this technique make it possible to perform anatomic repair in a wide variety of congenital anomalies of abnormal ventriculoarterial connection associated with pulmonary outflow tract obstruction without using the prosthetic material, even in infants, with relatively low mortality and morbidity.

A two-month-old female Yorkshire terrier was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Kyungpook national University. The patient was presented with a history of dyspnea, cough, exercise intolerance and abdominal distension, but she was appetence. In physical examination the puppy was coughed on slight tracheal compression. Rectal temperature, pulse and respiratory rate were normal, and grade 3/6 systolic murmur heard at the left heart base. The murmur was crescendo-decrescendo. Electrocardiography showed sinus arrhythmia, right-ventricular hypertrophy pattern, and right axis deviation. Thoracic radiography revealed cardiomegaly, bulging of the main pulmonary artery, and enlarged left side heart. Abdominal radiography revealed abdkominal distention. Echocardiography showed hypertrophy of right ventricle and turbulence in the pulmonary artery in parasternal oblique view. Subvalvular pulmonic stenosis was diagnosis based upon the clinical signs, physical examination, electrocardiography, radiography and echocardiography. We treated the patient with furosemide, enalapril and $\beta$-blocker. After the clinical signs of cough, abdominal distension and dyspnea were disappeared, she was on just $\beta$-blocker for prevention of occurrence of congestive heart failure. Now she was recovered her health, and she is not on any medication.

Transposition of the great arteries is one of the commonest forms of severe congenital heart disease and produces severe cyanosis threatening survival from the day of birth. Anatomical anomalies which the aorta arises from the infundibulum of the right ventricle and the pulmonary artery arises from the outflow tract of the left ventricle make the deranged circulation. Survival is possible only if additional anomalies are present which allow mixing of the pulmonary and systemic circulations. Preoperative diagnosis as TGA was taken on the 15 day old female via the preoperative examination and the right cordioangiography. As palliative treatment for cyanosis, Blalock-Hanlon operation was performed in this patient. The results were good as 54 mmHg changed from 27 mmHg of $PO_2$ in aorta, but sudden cardiac arrest was developed in postoperative 12 hours. In order to confirm the cause of death and the cardiac anomalies, autopsy was performed on the date of death. The diagnosis of the autopsy showed; [1] Transposition of the Great Arteries. [2] Patent Ductus Arteriosus. [3] Patent Foramen Ovale. [4] Ventricular Septal Defect, 2 Muscular Type. [5] Double Ureter, Right. [6] Artificial Atrial Septal Defect. [7] Total Collapse of the left lung and Intraparenchymal hemorrhage of right lung.

Within the group of congenital cardiac anomalies manifesting atrioventricular discordance, there exists a subset of hearts characterized by the additional presence of double outlet of the morphological right ventricle. Most of these hearts have associated pulmonary stenosis and abnormal direction of the cardiac apex, and all have a ventricular septal defect. Recently, a 10-year old boy underwent successful surgical correction of double outlet right ventricle with atrioventricular discordance. Diagnostic confirmation was made by 2-D echocardiography, cardiac catheterization and cineangiocardiography. The operation consisted of patch closure of ventricular septal defect so as to leave both great arteries draining the systemic[morphologically right] ventricle, and insertion of an extracardiac valved conduit between the morphological left ventricle and the distal end of the proximally oversewn pulmonary artery. Postoperative course was uneventful.
