Case Reports[A concomitant operation of Damus-Kaye-Stansel procedure, atrioventricular valvuloplasty and total cavopulmonary connection].
A 2-year-old girl with single ventricle and coarctation of aorta, who received subclavian flap aortoplasty and pulmonary artery banding at 30 days of age, developed subaortic stenosis and atrioventricular valve regurgitation. At the age of 2 years and 10 months, physiologic correction with atrioventricular valvuloplasty, Damus-Kaye-Stansel procedure, and total cavopulmonary connection were performed concomitantly. She showed uneventful convalescence, and postoperative cardiac catheterization revealed trivial atrioventricular valve regurgitation with a mild pressure gradient between the left ventricle and aorta.

Review Case Reports[Aortic valve replacement in a patient with chronic idiopathic thrombocytopenic purpura].
We reported a case of aortic valve replacement in a patient with chronic idiopathic thrombocytopenic purpura (ITP). We used high-dose intravenous gammaglobulin therapy (400 mg/kg/day) for five days to increase the platelet prior to the operation. The number of platelet was 8-10 x 10(4)/microliters at admission and it was increased to 23 x 10(4)/microliters before surgery. ⋯ The platelet was transfused after the bypass. Perioperative hemorrhage was moderate and postoperative course was uneventful. We believe that high-dose intravenous gammaglobulin therapy for ITP is effective to minimize perioperative hemorrhage for open heart surgery.

[Experimental studies of pulsatile retrograde cerebral perfusion].
This study was investigated for the effects of pulsatile flow on retrograde cerebral perfusion under profound hypothermic circulatory arrest. Fifteen adult mongrel dogs were placed cardiopulmonary bypass and induced profound hypothermia of 20 degrees C at nasopharyngeal temperature. Five dogs were performed non-pulsatile retrograde cerebral perfusion (NP-RCP) and 5 were pulsatile retrograde cerebral perfusion (P-RCP) for 60 minutes each group. ⋯ CSFP and ATP concentration in both of NP-RCP and P-RCP were significantly higher than those of HCA. Water content of cerebral tissue in P-RCP were significantly lower than those of NP-RCP. We concluded that retrograde cerebral perfusion for 60 minutes protects the brain as the assistances of circulatory arrest and retrograde cerebral perfusion with pulsatile flow has the possibility to control brain edema as compared with non-pulsatile flow in dogs.
