  • In this study general pharmacological profiles of KI-60606 on the central nervous system, the cardiovascular system and the other organs were investigated. The dosages given were 0,5, 10 and 25 mg/kg and drugs were administered intravenously. The animals used for this study were mice, rats, cats and guinea pigs. KI-60606 showed no effects on general behavior, motor coordination, spontaneous locomotor activity, hexobarbital-induced hypnosis time, body temperature, analgesic activity, anticonvulsant activity and contraction of nictitating membrane in cats. Furthermore KI-60606 showed no effects on blood pressure, heart rate, LVP (left ventricular peak systolic pressure), LVEDP (left ventricular end diastolic pressure), LVDP (left ventricular developing pressure), DP(double product), CFR(coronary flow rate), smooth muscle contraction using guinea pig ileum and gastric secretion at all dosage tested except the increase of gastrointestinal transport and urinary $K^+$ excretion.

  • Cardiac Myxoma is a most frequent benign tumor in primary cardiac tumors. About 75% occur in the left atrium & 20% in the right atrium, ventricular Myxoma is a very rare one among the cardiac myxoma. They may cause severe and progressive disease resembling valvular heart disease. With the advent of various diagnostic modalities, especially real time bidimensional echocardiography enabled us more accurate diagnosis of cardiac myxoma noninvasively and preoperatively. From April 1977 to Sept. 1981, 16 cases of cardiac myxomas were operated in Seoul National University Hospital using cardiopulmonary bypass. There were 13 cases of left atrial myxomas and each of a case was right atrial and right ventricular and left ventricular one. In all cases tumors were resected successfully & were discharged in healthy state. Follow up results of each patient was excellent.

  • Stent thrombosis is a rare complication after percutaneous coronary intervention (PCI), but it might be related to fatal outcomes. We report a case of patient who suffered from acute myocardial infarction complicated with cardiogenic shock and ventricular tachycardia caused by stent thrombosis and successfully resuscitated by percutaneous cardiopulmonary bypass support.

  • A five-month-old boy who had undergone previously transcatheter balloon atrioseptostomy at 3 days of age for complete transposition of the great arteries with ventricular septal defect and pulmonary stenosis underwent pulmonary root translocation with the Lecompte maneuver. This operation has the advantages of maintaining pulmonary valve function, preserving the capacity for growth, and avoiding problems inherent to the right ventricular to pulmonary artery conduit. This patient progressed well for 9 months postoperatively and we report this case of pulmonary root translocation with the Lecompte maneuver.

  • Isolated congenital left ventricular diverticulum is a rare cardiac malformation. Here, we report the case of a 33-year-old woman who had suffered from recurrent transient ischemic attacks for 6 years. Preoperative cardiac magnetic resonance imaging and computed tomography angiography revealed a diverticulum near the apex. The diverticulum was successfully obliterated by cardiopulmonary bypass. We suggest that isolated congenital left ventricular diverticulum can be easily corrected with a low surgical risk by patch repair and plication techniques.

  • Hemitruncus arteriosus is a rare cardiovascular malformation in which one of the pulmonary arteries anomalously originates from the aorta. Left hemitruncus arteriosus, defined as the origination of the left pulmonary artery from the aorta, is less common than right hemitruncus arteriosus. In this study, we report the case of a neonate diagnosed with left hemitruncus arteriosus, ventricular septal defect, and atrial septal defect who underwent successful surgical treatment.

  • In order to study the shape and dimensions of heart, the procedures to reconstruct a three dimensional left ventricular geometry from two dimensional echocardiographic images is studied including the coordinate transformation, curve fitting and interpolation utilizing three dimensional position registration arm. Nonlinear material property of the left ventricular myocardium was obtained by finite element method performed on the reconstructed geometry and optimization techniques which compare the computer predicted 3D deformation with the experimentally determined deformation. Afterwards using the obtained nonlinear material propertry the stress distribution related with oxyzen consumption rate was analyzed.

  • Shunt infections are a common complication of ventriculoperitoneal (VP) shunts, but the formation of a brain abscess related to a shunt system is very rare. A 44-year-old woman had a VP shunt inserted for hydrocephalus secondary to a subarachnoid hemorrhage. She suffered an episode of meningitis and sepsis 8 months after the shunt operation. After recovering from the meningitis, she complained of a loss of cognitive function. An enhancing mass was found in the frontal lobe, around the frontal horn of the lateral ventricle, and the ventricular catheter was embedded inside the mass. The ventricular catheter and cerebral abscess were removed using neuroendoscopy. We present an interesting case of a shunt-related brain abscess which illustrates the usefulness of neuroendoscopy.

  • Forty-five patients with double-outlet right ventricle[DORV] underwent complete intracardiac repair between July, 1983 and June, 1989. Patients with complete atrioventricular canal, atrioventricular discordance and uni-ventricular heart were excluded. The 32 male and 13 female patients ranged in age from 3 months to 15 years[mean 4 years]. Thirty-two patients had pulmonary stenosis. The early mortality was 11.ltd[5 /45] None of 27 died after a completely intraventricular repair. The mortality was 20%[1/5] for repair using transannular patch, 20% [1/5] for REV operation, 33.3%[1/3] for repair including extracardiac valved conduit, and 50% [1/2] for Jatene operation, respectively. Two modified Fontan procedures were performed without mortality. One died after Senning operation. Causes of early deaths included high residual right ventricular pressure[one patient] small left atrial and left ventricular volume[one patient], persisting severe pulmonary hypertension [one patient] and low cardiac output of unknown cause [two patients]. Complete heart block developed in one patient. Two late deaths occurred among the 40 operative survivors [5.0Po] from persisting severe pulmonary hypertension and bleeding at reoperation. Our results indicate that significant defects can be repaired with low mortality and morbidity.

  • Congenitally corrected transposition of the great arteries is a rare congenital heart anomaly, in isolation, has no hemodynamic consequences. It is usually associated with one or more of a variety of intracardiac lesions, ventricular septal defect, valvular or subvalvular pulmonary stenosis, and deformity of the systemic atrioventricular valve with insufficiency. This report describes a successful two stage operation for congenitally corrected transposition, [SLL] type, with ventricular septal defect, pulmonary atresia, persistent ductus arteriosus, and atrial septal defect. A 9 years old patient underwent modified Blalock-Taussig operation because of severe pulmonary hypoplasia. 2 years later a corrective operation, direct closure of ASD and PDA, VSD closure with Dacron patch, Enlargement of left pulmonary artery with pericardial patch and Relief of ROTO with Rastelli procedure could be successfully performed without complication.
