Truncus arteriosus is one of the rare cyanotic congenital cardiac anomalies and thought to be result from complete or partial failure of trunco-conal septum. A single arterial trunk receiving blood from both ventricles supplies the coronary, pulmonary and systemic circulation. The symptoms were usually related to the degree of the pulmonary blood flow and functional status of truncal valve, and mostly appeared within the first two months of life. The prognosis is generally considered to be poor in spite of successful surgical correction. This report is a case of 13 years old female with type I truncus arteriosus, which was successfully corrected using a intracardiac Dacron tunnel graft[semilunar, 18mm] from VSD to the truncal valve, and a extra-cardiac lonescu-Shiley valved[20mm] Dacron conduit [21mm] from RV to the pulmonary artery[Rastelli operation].

A 59-year-old woman was referred to our clinic for a glaucoma evaluation. The visual acuity and intraocular pressure were normal in both eyes. However, red-free fundus photography in the left eye showed a superotemporal wedge-shaped retinal nerve fiber layer defect, and visual field testing showed a corresponding partial arcuate scotoma. In an optical coherence tomography examination, the macula was flat, but an arcuate-shaped peripapillary retinoschisis was found. Further, the retinoschisis seemed to be connected with a superotemporal optic pit shown in a disc photograph. After 3 months of a topical prostaglandin analogue medication, the intraocular pressure in the retinoschisis eye was lowered from 14 to 10 mmHg and the peripapillary retinoschisis was almost resolved. We report a rare case of an optic disc pit with peripapillary retinoschisis presenting as a localized retinal nerve fiber layer defect.

The pericardial adhesions following the first open heart surgery pose a major problem that can increase the morbidity and mortality in cases of reoperation because of the danger of damaging the heart, great vessels or grafts. The purpose of this study was to determine the effect of intrapericardial infusion of 5% dextrose solution and heparin on experimental pericardial adhesions. The 15 white rabbits were divided into three treatment groups of 5 animals each: group 1 [control group], group 2[5% dextrose group] and group 3 [heparin group]. At 4 weeks, all animals were sacrificed and the pericardial adhesions were graded as follows: 1[none], ll[mild], Ill[moderate] and IV[severe]. Histological examination was performed on a subset of each group. The difference of adhesion between control and heparin group was evaluated by Chi-square analysis. The results were as follows: 1. Pericardial adhesions developed in 80% of animals in group 1 and 2. 2. Only 40%> of animals in group 3 had mild to moderate pericardial adhesions. This was significantly different from the control group [P=0.01]. 3. Histological examination showed that the pericardium with adhesion was thickened with fibrosis, while that without adhesion was thin, normal appearance. 4. In group 3, there was no evidence of hemorrhage or hemorrhagic tendency in the pericardium.
