The association of aortopulmonary window and tetralogy of Fallot is rare. The aortopulmonary window lies usually between the left side of the ascending aorta and the right wall of the pulmonary artery just anterior to the origin of the main pulmonary artery. Recently, we experienced a case of aortopulmonary window associated with tetralogy of Fallot in a 4 years old male. Operation was done under the Impression of the tetralogy of Fallot. On operation, the anomaly was confirmed as aortopulmonary window[type 1] and tetralogy of Fallot. The aortopulmonary window was closed with Gortex patch via the main pulmonary artery and tetralogy of Fallot was repaired. Postoperative course was uneventful.

Ninety-six patients with tetralogy of Fallot have undergone either primary total correction [71], staged total correction [9], or an initial shunt [16], between January, 1984, and December, 1987 Their mean age was 9.5 years, mean body weight 24kg, and mean body surface area 0.86m2. Initial palliative shunt group had smaller size, smaller pulmonary artery, and higher hemoglobin [P value < 0.05 >. Modified Blalock-Taussig shunt was performed most commonly. Patch enlargement of right ventricle in 31 cases [38%], right ventricle and pulmonary artery in 7 cases [9%], transannular patch enlargement in 28 cases [35%], and valved conduit in 2 cases [2.5%] was performed for reconstruction of right ventricular outflow tract stenosis. Longer aorta cross clamp time was noted in case of separate patch enlargement of right ventricle and pulmonary artery, and dead patient with transannular patch enlargement [P value < 0.05]. There was no operative death in shunt group, but 7 deaths in total correction group [mortality rate 8.8%].

The prevalence of canine heartworm(Dirofilaria immitis) infection in 150 mixed-breed dogs(male : 54, female : 96) from February to December 1997 was investigated by using antigen test kit(ICT $GOLD^{TM}$ HW, Synbiotics, USA) based on immunochromatographic assay in Inchon city. Also, gross and histopathological findings of an antigen positive dog were carried out. The results were summarized as follows ; 1. Four dogs were positive from 150 tested dogs(2.7%). They were all more than 2 years old and infection rates in male and outdoor dogs was higher than those in female and indoor, respectively. Species of infected dogs were Pug(2) , German Sheperd(1) and Great-dane (1). 2. Regional infection rates were closely related with housing system in the city. 3. Pathological findings of antigen-positive dog was excessive enlargement, congestion and hemorrhage of lung and D immitis in heart and histologically hemosiderin, hypertrophy of pulmonary alveoli wall and irregular hypertrophy of pulmonary artery inner wall. Microfilaria was observed in pulmonary artery and arteriole, ventricle and splenic artery.

Unilateral hypoplasia of the pulmonary artery is an uncommon anomaly, which commonly develops in combination with congenital cardiovascular defects such as tetralogy of Fallot, patent ductus arteriosus and septal defect of atrium or ventricle, but may also present as an isolated lesion. We have recently experienced a case of the left pulmonary artery hypoplasia in adult by chance of during the general health screen, which diagnosed by chest X-ray, chest spiral CT, lung perfusion and ventilation scan, digital substraction angiogram and bronchoscopy, then presented hereby with the review of relevant literature.

Pulmonary sequestration is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and receives its blood supply from an anomalous systemic artery. We present a case of extralobar pulmonary sequestration experienced recently. The patient was 13 month old female with a complaint of fever, coughing and tachypnea. Chest film showed large homogeneous opacity in left lower lung field. At operation, a homogeneous mass was located between the left upper lobe and lower lobe, measuring 4X6X5cm in dimension. The aberrant artery was originated from the descending thoracic aorta, 1 cm in length and 3 mm in diameter. After division and ligation of the aberrant artery, sequestrectomy and lingular segmentectomy was done due to abscess formation. The postoperative course was smooth. She was discharged on postoperative thirteenth day.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.

Pulmonary sequestration is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and receives its blood supply from an anomalous systemic artery. Extralobar form is a very rare congenital malformation. We have experienced a 54 year old female patient with a mass in the upper lobe complaining of cough and blood tinged sputum. A triangular shaped mass was located in the left upper lobe, medially. The arterial blood supply were from the thoracic aorta and the pulmonary artery but there was no the tracheobronchial communication. The venous drainage was through the pulmonary vein. The mass was confirmed as extralobar pulmonary sequestration associated with a pericardial defect.

Pulmonary sequestration is an uncommon congenital malformation characterized by the presence of non-functioning lung tissues which receives its blood supply from an anomalous systemic artery instead of a pulmonary arterial branch. We present a case of intralobar pulmonary sequestration experienced lately. The patient was 7 years old girl with the complaints of chronic productive cough and right lower chest pain. Serial chest films showed a large cyst with or without a air-fluid level on the right lower lung field. Aortography revealed an aberrant artery originating from thoracic aorta just above the diaphragm and that drained into the right inferior pulmonary vein. During operation, a large abscess cavity measuring 6.5x5x5 cm in dimension at the right lower lobe was noted. And the two aberrant arteries, measuring 3 mm in diameter, arising from thoracic aorta 5 cm above the diaphragm was noted. After division and ligation of the aberrant arteries, right lower lobectomy was performed and the patient`s postoperative course was uneventful.

A sequestrated Mass of ectopic non functioning pulmonary Tissue artery is an uncommon but clinically recognizable Entity. Pulmonary sequestrated, in general usage, designates an intralobar process intralobar pulmonary sequestration is a rare congenital malformation characterized by a cystic portion of the lung that derive its arterial blood supply through aberrant vessel directly of systemic circulation. As aberrant systemic vessel supplying the lung was reported by Hurber in 1777. We experienced a case of Intralobar pulmonary sequestration Pre-Operatively, confirm by Aortogram. The operative finding show that large Abscess cavity measuring 7x8 Well circumscribed, child fist sized Mass, and 4cm-length aberrant vessel arising from Descending aorta Just above the Diaphragm. The Anomalous systemic artery was ligatures & resection, and associated with left lower lobectomy was done. Post-Operative course was uneventful, and 7 days later discharged.

We report a modified technique for pulmonary endarterectomy (PEA) on a 67-year-old man with chronic thromboembolic pulmonary hypertension (CTEPH) who presented with dyspnea. He was referred to our medical center for coronary artery bypass grafting. CTEPH had not been detected in his first visit to another medical center, but upon re-evaluation, the diagnosis was confirmed. PEA was performed with a modified method, which seems to be safe and suitable for the removal of clot and fibrotic materials. Iatrogenic dissection was performed with normal saline injection in the pulmonary artery, and then, the clot was removed completely. Although the technique may not be applicable for all cases, it can be used as an alternative to using an aspirating dissector and a pair of forceps.
