  • Intralobar pulmonary sequestration is a rare congenital malformation characterized by a cystic portion of the lung that derives its arterial blood supply through aberrant vessel directly of systemic circulation. Intralobar pulmonary sequestration Is usually contained within the visceral pleura of a pulmonary lobe and its venous drainage to the pulmonary venous system. We experienced a case of pulmonary sequestration preoperatively confirmed. The patient was 17 year old female whose complaints were mild fever and profuse purulent sputum. Chest film showed a large thin walled cystic lesion with air-fluid level at the left lower posterior basal lung field. Aortogram revealed an aberrant artery originated from thoracic aorta just above the diaphragm and that drained via pulmonary vein into the left atrium. At time of operation, a large abscess cavity measuring 9x8x3 cm in dimension at the left lower lobe was noted. And the aberrant artery, measuring 0.5 cm in diameter and 2 cm in length, arising from thoracic aorta just above the diaphragm was noted. After division and ligation of the aberrant artery, a left lower lobectomy was performed and the patient`s postoperative course was uneventful.

  • A new mathematical model of pumping heart coupled to lumped compartments of blood circulation is presented. This lumped pulsatile cardiovascular model consists of eight compartments of the body that include pumping heart, the systemic circulation, and the pulmonary circulation. The governing equations for the pressure and volume in each vascular compartment are derived from the following equations: Ohm's law, conservation of volume, and the definition of compliances. The pumping heart is modeled by the time-dependent linear curves of compliances in the heart. We show that the numerical results in normal case are in agreement with corresponding data found in the literature. We extend the developed lumped model of circulation in normal case into a specific model for arrhythmia. These models provide valuable tools in examining and understanding cardiovascular diseases.

  • Intralobar pulmonary sequestration is rare congenital lung disease characterized by a cystic portion of the lung that derives its arterial blood supply though aberrant vessel directly of systemic circulation. Intralobar pulmonary sequestration is usually contained within the visceral pleura of a pulmonary lobe and its venous drainage to the pulmonary venous system. We experienced a case of pulmonary sequestration postoperatively confirmed. The patient was 48-year-old female whose complaints were cough and left chest pain. Chest film showed large homogenous opacity in left lower lung field. By operation, adult fist sized mass at the lower lobe were noted. An aberrant artery, measuring 1.0 cm. in diameter and 2.0 cm. in length, arose from the descending thoracic aorta just above the diaphragm. The anomalous systemic artery was ligatures and resection, and associated with left middle, lower bilobectomy was done. The postoperative course was uneventful, and 10 days later discharged.

  • 체동맥-폐혈관루(systemic artery to pulmonary vessel fistula, SAPVF)는 비정상적으로 형성된 체동맥과 폐혈관 사이의 연결이다. 이는 대부분 선천적으로 발생하지만, 드물게는 폐나 흉막의 종양, 염증성 질환 및 외상 등으로 인해 발생할 수 있다. 내원 16년 전 교통사고로 인한 횡경막 파열로 수술한 과거력이 있는 38세 남자 환자가 객혈을 주소로 내원하였고, 흉부 컴퓨터 단층 촬영과 혈관 조영술로 늑간동맥 및 내흉 동맥과 폐혈관이 연결된 SAPVF를 진단하였다. 저자들은 외상에 의한 SAPVF 1예를 경험하였고, 혈관 색전술을 시행하여 좋은 결과를 얻었기에 국내 문헌상으로는 최초로 이를 보고하는 바이다.

  • Complete TGA is a common congenital cardiovacular anomaly, and without palliative or corrective surgery, the infant born with TGA rarely survives the first year of life. Hemodynamically, recirculated blood flow in the systemic and pulmonary circuit has a key role in systemic arterial oxygen saturation and the status of the pulmonary vascular bed. Recently a d-TGA with VSD and PS, in a 12 year old male patient had been tried for inversion of the ventricular flow with Rastelli operation. An intracardiac tunnel was constructed between the VSD and the aortic orifice to connect the ventricle to the aorta. The right ventricle was connected with the pulmonary circulation by anastomosis of an valved conduit between the right ventricle and the distal end of the pulmonary artery. During the postop, period, the irreversible renal failure, accompanied by metabolic acidosis and pulmonary edema, occured under relative stabilized cardiac performance state. The autopsy was done, which revealed diffuse infarcted area in both kidney and preserved intra & extracardiac graft constructed.

  • Bilateral coronary artery-pulmonary artery fistula is very uncommon congenital heart disease which occupy small percentage of all coronary arterio-venous fistulas. We experienced a case who was 52 years old female with bilateral coronary artery-pulmonary artery fistula. She complained exertional dyspnea k angina[coronary steal syndrome]. On physical examination, any cardiac murmur was not audible. There was no 0y step-up in right heart catheterization. But selective coronary angiography revealed tortuous aberrant vessels which originated from the canal branch of the right coronary artery k the left anterior descending coronary artery. Both aberrant vessels traversed the right ventricular outflow tract, and conjoined just proximal the pulmonic annulus and drained into the main pulmonary artery. The operation was performed under the extracorporeal circulation with beating heart. The procedures were suture-ligation of the draining orifice in main pulmonary artery & the feeding vessels on the right ventricular outflow tract. Postoperatively her complaints were completely disappeared and the selective coronary angiography revealed no left-to-right shunt.

  • 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.

  • TAPVC represents 1 to 4% of all congenital cardiac defects. Generally severe and refractory cardiac failure develops in the majority of patients in the early infancy. In a small minority of patient, they are relatively asymptomatic in infancy, but symptoms will develop of necessity In the later life. Our three cases had dyspnea on exertion and cyanosis and had a history of frequent respiratory infections. All 3 cases had the typical showman configuration on roentgenograms of the chest. Current surgical therapy has greatly altered the unfavorable course of these patients after institution of extra-corporeal circulation. We have experienced three cases from June, 1973 to May, 1983, the patients were undergone complete repair with extracorporeal circulation at the Department of Thoracic and Cardiovascular Surgery in the Yonsei University. The ages ranged from 12 years to 14 years, all cases were supracardiac type of TAPVC. Only one case died due to bleeding from anastomosis site between LA and pulmonary venous trunk. In the remaining two patients with complete corrections of TAPVC, there was excellent relief of symptoms such as dyspnea and cyanosis. Their postoperative course have been good during follow-up.

  • This is one case report of the extremely rare congenital cardiac malformation, Double-outlet of left ventricle in corrected transposition of great arteries. 11-year-old boy complained acrocyanosis and exertional dyspnea, the parents noticed cyanosis since birth. Physical examination revealed acrocyanosis, clubbed fingers and toes, G-III pansystolic murmur on 2nd and 3rd ICS, LSB. Right heart catheterization revealed significant $O_2$ jump in ventricular level. Right and left ventriculography showed the both catheters arriving in the same ventricle i.e. anterior chamber, morphological left ventricle was in right and anterior position, simultaneous visualization of aorta and pulmonary artery and aorta locating anterior and right side of pulmonary artery. Echo cardiogram surely disclosed interventricular septum. Conclusively it was clarified that the patient has Double-outlet of left ventricle and corrected transposition of great arteries [S.L.D.]. Operation was performed to correct the anomalies under extracorporeal circulation with intermittent moderate hypothermia. Right-sided ventriculotomy disclosed the following findings. 1. Right-sided ventricle was morphological left ventricle. 2. Left-sided ventricle was morphological right ventricle. 3. Right side atrioventricular valve was bicuspid. 4. Left side atrioventricular valve was tricuspid. 5. Aortic valve was superior, anterior and right side of pulmonary valve. 6. Subpulmonary membranous stenosis. 7. Non-committed ventricular septal defect. We made a tunnel between VSD and aorta with Teflon patch so that arterial blood comes through VSD and the tunnel into aorta. After correction the patient needed assisted circulation for 135 min. to have adequate blood pressure. Postoperatively by any means, adequate blood pressure could not be maintained and expired in the evening of operation day.
