Background: Recently, open heart surgerys using homograft are progressively increasing in complex cardiac anomalies, and even though the use of homograft tissues harvested from hearts of transplant recipients and brain-death patients are allowed and their use is increasing, the supply of homograft tissue is very limited. Material and Method: The large diameter homografts are difficult to apply directly for RVOT reconstruction of small neonatal and infant hearts due to the size mismatching. Therefore, were surgically down-sized the large diameter tricuspid homograft into bicuspid conduits by means of a longitudinal incision of the oversized homograft, excision of one cusp, and oversewing of the“Bicuspid homograft”wrapped around a Hega dilator of the appropriate size. Result: 3 patients(Male 1, Female 2: tetralogy of Fallot with pulmonary atresia), ranging in age from 5 months to 4 years and ranging in weight from 5.5Kg to 12.95Kg underwent reconstruction of the RVOT with bicuspid conduits obtained by appropriate tailoring from large-diameter homografts. The mean follow-up period was 4.3 months(range, 2 to 6 months). There were no complications related to the homograft tissues. Conclusion: In the short term follow-up, the bicuspid homografts provided good competence and excellent hemodynamics although a long term follow-up is needed to assess the functions of the bicuspid homografts in RVOT. We believe this technique may be a more effective alternative than the use of synthetic conduits when the use of an appropriate-sized homograft is not possible.

Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.

Coronary artery fistula accounts for $0.27\~0.4\%$ of all congenital cardiac defects. In more than $50\%$ of the cases, right coronary artery is involved. The fistula drains into the right heart in $92\%$ of the cases. Left heart is the site of termination in only $8\%$ of the cases, especially less left ventricle $(3\%)$. We experienced a case of right coronary artery to left ventricular fistula in a 3-year-old boy who was diagnosed incidentally and underwent ligation of fistula.

This is a case of successfully surgically treated RVOT obstruction caused by projection of the herniated aortic cusp through subpulmonic supracristal VSD at Department of Thoracic and Cardiovascular Sugery, Hanyang University Hospital. The patient was a 17 year old boy. Congenital heart anomaly was suspected at 2 years of his age. He had palpitation, dyspnea on exertion and epistaxis for 2 years prior to admission to our hospital. On examination, the blood pressure was 170/0mmHg. And the pulse rate was 100/rain. Widening of pulse pressure, water hammer pulse [bounding pulse]. To and fro murmur and head nodding were noted. Cardiomegaly was seen in chest x-ray. EKG, Echocardiography, Cardiac catheterization and angiocardiography were performed. On April 27, 81. Open heart surgery was performed under the impression of VSD combined with AI. On Rt. ventriculotomy, we noticed RVOT obstruction caused by prolapsed rt coronary cusp through a VSD. The subpulmonic supracristal VSD measuring 2.5 x 3 Cm in diameter was closed with Teflon patch graft and then the prolapsed aortic leaflet was plicated by placing three 8-figure suture between the free edge and the base of the leaflet through transverse aortotomy. After operation, excellent result was obtained: B.P, was 110/50mmHg and any sign of AI or residual shunt was not found at discharge.

Central anticholinergic syndrome is defined as an absolute or relative reduction in cholinergic activity in the central nervous system and has a wide variety of manifestations. It is associated with almost any drug given during anesthesia, except neuromuscular relaxants, and treated with the cholinesterase inhibitor physostigmine. The diagnosis of central anticholinergic syndrome is often made when symptoms resolve promptly after the administration of physostigmine. We present a case of a central anticholinergic syndrome diagnosed by treatment with physostigmine, in a patient who received closure of patent foramen ovale associated with stroke.

A 4-year-old intact male Shih Tzu dog (weighing 5 kg), was presented with signs of severe dyspnea, exercise intolerance and cyanosis. Diagnostic studies suggested a reverse patent ductus arteriosus (rPDA) with pneumonia. Despite emergency treatments with oxygen, diuretics, antibiotics and medical therapy for hyperkalemia, the dog died of ventricular fibrillation from hyperkalemia and dehydration. Necropsy revealed the rPDA with a marked descending aortic dilation and abnormally arisen left common carotid artery.

In this paper,we propose a novel technoque of improving volume rendering quality and speed by integrating volume data and global shape information together. The selective volume rendering method is to generate distance transformed volume using a distance transform to determine the minimum distance to the neaest intercsting part and then render it. The shape information prevents from object occlusions come from similar intensity of each object. Thus it provides effective visual results that enable to get a clear understanding of complex structures. We show the results of selective volume rendering method for left ventricle and right ventricle ans well as the results of selective sampling methods depending on the interpolation from EBCT cardiac images. Our method offers an accelerated technique to accurately visuahze the surfaces of devined objects segmented from the volume.

Twenty-seven patients with double-outlet right ventricle underwent complete intracardiac repair between 1978 and 1983, June, at Seoul National University Hospital . Although definite aorto-mitral discontinuity was discovered in 20 patients, both great arteries arose wholly or mostly from the right ventricle in all cases. There were 17 cases with subaortic VSD, 6 with subpulmonic, 2 with doubly-committed, and 2 with non-committed VSD. Pulmonary stenosis was present in 21 patients. Intraventricular baffle repair was applied in 23 patients. Three patients required extracardiac conduit to establish continuity between right ventricle and pulmonary artery, and modified Fontan operation was performed in one patient. Over-all mortality rate was 37.0%, but recently 4 of 15 died [26.7%]. One late death occurred from infective endocarditis. Incremental risk factors were small patient size, subpulmonic or non-committed VSD, presence of PS, coronary artery anomalies, associated valvular lesion and other complicated anomalies. However, great artery relationship, restrictive VSD and transannular patch were not risk factors. No instances of complete heart block occurred. Of the survivors, all showed complete or in complete right bundle branch block and in one patient intermittent ventricular tachycardia had developed. The important cause of death was low cardiac output syndrome.

A 43-year-old male patient visited our hospital because of intermittent chest pain and exertional dyspnea. This patient was diagnosed as suffering with pulmonary stenosis that was caused by muscle hypertrophy of the subpulmonic area, and the diagnosis was made by performing echocardiography and cardiac catheterization. A sternal foramen of the chest wall was found on the operation field. We report here on this case and we also review the relevant literature.
