Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

The half-turned truncal switch (HTTS) operation has been reported as an alternative to the Rastelli or $r{\acute{e}}paration$ $\grave{a}$ $l^{\prime}{\acute{e}}tage$ ventriculaire procedures. HTTS prevents left ventricular outflow tract (LVOT) obstruction in patients with complete transposition of the great arteries (TGA) with a ventricular septal defect (VSD) and pulmonary stenosis (PS), or in those with a Taussig-Bing anomaly with PS. The advantages of the HTTS procedure are avoidance of late LVOT or right ventricular outflow tract (RVOT) obstruction, and of overstretching of the pulmonary artery. We report the case of a patient who underwent HTTS for TGA with VSD and PS, in whom there was no LVOT obstruction and only mild aortic regurgitation and mild RVOT obstruction, including observations at 12-year follow-up. Our experience with long-term follow-up of HTTS supports a solution for late complications after the Rastelli procedure.

Truncus ateriosus is one of the cyanotic congenital heart disease. The incidence is relatively uncommon, as 0.4% of totoal congenital heart disease. Embryologically the defect is due to a lack of partitioning of the embryonic truncus and conus during the first few weeks of fetal life. The ventricular septal defect is invariable present. A single arterial vessel arises from the heart and supplies blood to the aorta, the lung, and the coronary arteries. In 1949, collett and Edwards classified this defect according to anatomic variation to four major types, such as type I, II, III, and IV. Type IV is defined that pulmonary arteries are absent, and the pulmonary arterial supply arises from the descending thoracic aorta. This patients often have a continuous murmur head particularly well in the interscapular area. No effective surgical treatment is available. We have experienced one case of truncus arteriosus, type IV of Collett and Edwards in the Department of Thoracic and Cardiovascular Surgery, Kyungbook National University Hospital. This patient was 10 year-old girl. The chief complaints were cyanosis and dyspnea on exertion since birth. She was admitted at this hospital on April 16, 1980. The continous machinery murmur was heard loudest at the interscapular area. The chest X-ray films revealed cardiomegaly with an increase in pulmonaryvascular markings. The pulmonary secotr was significantly concave. No filling of pulmonary arteries noticed by the right ventriculogram. There was possible biventricular hypertrophy in EKG. The echocardiogram showed that the demension of the aortic root was larger than normal and minimal increase of the left ventricular internal dimension. The cardiac catheterization data was obtained by use of the great saphenus vein approach. The systolic pressure of the right ventricular outflow tract was 80 mmHg and was similar to that of the aorta. The oxygen saturation data revealed the evidence of the left to right shunt at the level of ventricular septum. The patient was operated and the diagnosis was confirmed as trucus arteriosus, type IV. No effective surgical interventins were performed.

Takayasu's arteritis is a chronic inflammatory disease, involving mainly the aorta and its main branches, which can cause stenosis or occlusion. It involves the bracheocephalic, carotid, subclavian, vertebral, and renal, as well as the coronary and pulmonary arteries. The clinical manifestations range from asymptomatic to catastrophic, with dizziness, hypertension, claudication, cerebral infarction, chest pain and dyspnea. Takayasu's arteritis involving the pulmonary arteries, but not the aorta and its main branches, is very rare. Herein, a case of isolated pulmonary Takayasu's arteritis combined with pulmonary thromboembolism, and hyperthyroidism is reported, with a review of the literature.

Tetralogy of Fallot associated with a single pulmonary artery is a rare cardiac anomaly. In previously reported cases, left pulmonary arteries were absent except 2 cases. Congenital absence of the pulmonary valve is a rare anomaly too. In the majority of cases, this lesion is associated with TOF. TOF associated with a single pulmonary artery and absent pulmonary valve is a very rare anomaly and only less than 20 cases were reported in the literatures. We have operated on one patient with TOF associated with absent right pulmonary artery and rudimentary pulmonary valve, a variant of absent pulmonary valve, and report this case with review of the literatures.

Background : A pulmonary embolism often presents with nonspecific symptoms and signs. However, a delayed diagnosis can result in catastrophic outcome. The majority of preventable deaths associated with a pulmonary embolism can be ascribed to a missed diagnosis rather than to the failure of existing treatments. Therefore, accurate and rapid diagnostic methods are essential for the management of a pulmonary embolism. The recent generation of multidetector-row spiral CT scanners appears to outperform other imaging modalities in detecting a central and peripheral pulmonary embolism. However, there are some variations in the interpretations of the findings between observers. This study examined the inter-observer differences of the diagnoses in patients with a pulmonary embolism. Method : 64 patients who were diagnosed with a pulmonary embolism either clinically or with spiral chest CT from 2002 to 2004, were included. Two thoracic radiologists interpreted the multidetector-row spiral CT in terms of the diagnosis of a pulmonary embolism and the location of the thrombus independently. Among 64 patients, 14 patients were excluded because there was no evidence of a pulmonary embolism or there was different interpretation of the pulmonary embolism between radiologists. A clinical diagnosis was based on "Rules for predicting the probability of embolism". Results : The mean score of the patients according to the Wells method was $3.91{\pm}0.30$ (0-9). The accordance of the radiologists was 95% in the main, 85% in the lobar, 91.2% in the segmental, and 96% in the sub-segmental pulmonary arteries. After excluding the negative interpretation from both radiologists, their agreement was 76.2%(${\kappa}.$ 0.83) in the main, 57.6%(${\kappa}.$ 0.63) in the lobar, 51.5%(${\kappa}.$ 0.63) in the segmental, and 34.6%(${\kappa}.$ 0.49) in the sub-segmental pulmonary arteries. Conclusion : Chest CT has been recently applied to patients suspected of having a pulmonary embolism. It was found that spiral CT is a rapid test for diagnosing a thrombus, and there was reliable accordance between the observers from the area of the large pulmonary arteries. However, there was a lack of agreement between the observers in diagnosing thrombi located distal to the sub-segmental arteries.

We have experienced a case of intralobar pulmonary sequestration communicating with the esophagus. A 24 year old female patient was admitted of chronic cough related to food, purrlent sputum and left lower chest pain. Esophagography and bronchography revealed bronchoesophageal fistula and bronchiectasis with cystic lesion of the left lower lobe. There was multiple anomalous feeding vessels arinig from the intercostal arteries and no draining systemic vein on aortography. division of the bronchoesophageal fistula and left lower lobectomy was performed. Communication with the esophagus in rarely associated with intralobar pulmonary sequestration and esophagogram is useful method of diagnosis for this communication.

Wegener's granulomatosis is a systemic vasculitis of the medium and small arteries, as well as of the venules, arterioles, and occasionally large arteries, and primarily involves the upper and lower respiratory tracts and the kidneys. Renal symptoms of Wegener's granulomatosis are indistinguishable from those of vasculitis such as Henoch-$Sch\ddot{o}nlein$ purpura and microscopic polyangiitis. This case, though initially diagnosed as Henoch-$Sch\ddot{o}nlein$ purpura, was confirmed as Wegener's granulomatosis from a lung biopsy fifteen years after the initial diagnosis. We report this case with a review of the literature.

Pulmonary atresia with VSD is uncommon congenital anomaly with high mortality in neonatal period. Recently we experienced surgical correction of 2 cases of pulmonary atresia with VSD. The first case was 7-year old female patient and diagnosed as pulmonary atresia with VSD combined PDA. So, total correction was undertaken which consisted of PDA ligation, patch repair of VSD, transannular enlargement of RVOT with woven Dacron vascular graft, and closure of PFO. Postoperative systemic Rt. ventricular and radial artery pressure ratio was 0.44 and her postoperative course was uneventful. The second case was 6-year old male patient diagnosed as pulmonary atresia with VSD and large systemic-pulmonary collateral arteries. There were two large systemic-pulmonary collaterals, one was simply controlled by ligation, but the other was considered to supply Rt. upper lung. So end to side anastomosis was performed to the RVOT patch. Postoperative systolic Rt. ventricular and radial artery pressure ratio was 0.54. During the follow up period he showed clinical picture of Rt. heart failure, which is relatively well controlled with anticongestive therapy.

A surgical correction was successfully performed in a adult female who had pulmonary atresia with almost non-confluent pulmonary artery, PDA and ventricular septal defect. Initially as a first stage of corrective surgery isolation of patent ductus arteriosus, ligation of aortopulmonary collaterals and identification of the pathologic anatomy of left pulmonary artery through left posterolateral approach were performed. At the second stage, a week after the initial operation, total correction was done making both pulmonary arteries confluent with albumin coated woven-dacron graft, external valved conduit and closure of large VSD of subarterial and perimembranous type. The PDA was ligated with previously encircled heavy stitch soon after partial bypass was started. Although massive bleeding from anastomotic site of dilated left pulmonary artery to the graft occurred preoperatively, postoperative functional improvement was excellent in terms of disappearance of cyanosis and normal exercise tolerance.
