We report a case of the successful anatomical correction of the Taussig-Bing anomaly associated with the interrupted aortic arch and intramural left coronary artery for an 38 day-old infant. Aortic arch and neoaortic reconstructions were conducted without any prosthetic or pericardial patch. Intramural left coronary was separated from right one after partial detachment of aortic commissure and both coronary artery buttons were transferred separately to the proximal main pulmonary artery(neo-aorta). Delayed sternal closure was done 3 days after the operation and hospital discharge was delayed for a month because of postoperative pneumonia. Now he is 5 months old and free of symptoms and cardiac drugs.

BACKGROUND: Follow-up studies have shown that although outcomes have improved substantially over time,results of the Fontan operation and its modifications remain suboptimal.In this study,we reviewed our experience with the extracardiac conduit Fontan operation,with a focus early and midterm change of internal diameter of PTFE conduit. MATERIAL AND METHOD: Between April 1997 and July 2000 were reviewed.Twelve patients (M:6,F:6,mean age 42.04 +/- 12.43months,mean body weight 13.80 +/- 1.94kg)underwent extracardiac conduit Fontan operation with expanded PTFE graft.Mean cardiopulmonary bypass time was 109.7 +/- 26.99minute and mean operation time was 455 +/- 89.51minute. Intraoperative fenestration was performed in 10 patients.The aortic cross clamping was not performed in all patients. RESULT: There was no early deaths and no postoperative dysrhythmia. Postoperative protein losing enteropathy and prolonged pleural effusion occurred in 1(8.3%)and 4 patients(33.3%).Conduit patency was evaluated by magnetic resonance imaging studies.A 9.84 +/- 3.84%mean reduction in conduit internal diameter and there was no statistical correlation between the change of internal diameter of conduit and the postoperative duration after partial correlation analysis(r=0.019,p=0.955). CONCLUSION: These results demonstrate that the extracardiac conduit Fontan operation provies good early and midterm results and may reduce the prevalence of late arrhythmia.And there is no correlation between the change of internal diameter of conduit and the postoperative duration after extracardiac conduit Fontan operation with the expanded PTFE graft conduit.

BACKGROUND: It is known that low birth weight is a risk factor for poor outcome in cardiac surgery for many cardiac defects.We reviewed our recent surgical experiences on congenital heart defect (other than patent ductus arteriosus)in low birth wei ght babi es.Material and METHOD: From September 1994 to February 2001,31 consecutive infants weighing 2500 g or less underwent cardiac surgery with (OHS group n=12)or without cardiopulmonary bypass (CHS group n=19).A retrospective study was carried out to evaluate short-and intermediate-term outcome.Mean gestational age and age at operation were 36.9 weeks(range,32.3-42weeks)and 32.1days (range,0-87days)respectively.Mean body weight at birth and operation were 1972g (range,1100-2500g)and 2105g (range,1450-2500 g)respectively.There was no difference between the two groups in age and body weight.Defects included ventricular septal defect (VSD)(n=3),VSD with arch anomaly (n=2),total anomalous pulmonary venous return (n=2),transposition of the great arteries (TGA)(n=2),truncus arteriosus (n=2),and univentricular heart with cor triatriatum (n=1)in OHS group,and coarctation of aorta (n=7),tetralogy of Fallot (TOF)(n=3),TOF with pulmonary atresia (n=3), multiple muscular VSDs (n=1),double outlet right ventricle (n=1),pulmonary atresia with intact ventricular septum (n=2),tricuspid atresia (n=1),and TGA with multiple VSD (n=1)in CHS group.13 patients (41.9%)were intubated pre-operatively. RESULT: There were 4 early deaths (<30 days);1 (8.3%)in OHS group and 3 (15.8%)in non-OHS group.All these early deaths were related to the pulmonary artery banding(PAB).There was no operative mortality in infants undergoing complete repair and palliative operations other than PAB.Delayed sternal closure was required in 3 patients.Prolonged postoperative mechanical ventilation (>7days)was required in 7 patients (58.3%)in OHS and 7 (38.8%)in CHS group.Late mortality occurred in 3 patients,two of which were non-cardiac.A patient in OHS group was documented to have neurologic sequelae.All the survivors except two are in NYHA class I. CONCLUSION: Complete repair and palliative operations other than PAB can be performed in low birth weight infants with low operative mortality and an acceptable intermediate-term result.However,about a half of the patients required long-term postoperative mechanical ventilation.

Extranodal lymphoma presents in almost one-third of all non-Hodgkin lymphoma cases. The gastrointestinal tract, skin, and central nervous system are common sites of involvement, whereas the urethra and cervix are very rare. To the best of our knowledge, this is the first report on concurrent extranodal involvement of the uterine cervix and urethra. We report imaging findings of malignant lymphoma involving urethra and cervix concurrently in a 79-year-old female patient with literature review. The magnetic resonance imaging showed huge intermediate to high signal intensity mass on T2 weighted images and strong homogeneous enhancement in uterine cervix and periurethral area, but no surrounding architectural disruption.

Hypersensitivity to the stings of the Hymenoptera has been described since antiquity. The hypersensitive reactions to insect stings vary from minor skin reactions to severe and sometimes fatal anaphylaxis. Concerns about sting hypersensitivity have been increasing because of many incidents of allergic reactions of patients to the fire ant in the southern area of the United States as well as the harvester ant in some areas. We experienced one unique case with severe allergic reactions by ant of the Ectomomyrmex spp. of the subfamily Ponerinae, which is not a harvester ant. For three years the patient had been suffering from generalized allergic reactions such as anaphylaxis after the ant stings four-five attacks in a year. We determined that her reactions were due to specific IgE mediated type I hypersensitivity by the detection of a high level of specific IgE to the ant venom in her serum. The high level of specific IgG4 to the ant venom was also noted in her serum, however, the role of ant venom IgG4 was not clearly determined.

Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.
