[Emergent coronary bypass grafting after acute myocardial infarction].
In an attempt to examine various factors affecting the short- and long-term results of emergent coronary bypass graft surgery (ECABG) after an acute myocardial infarction (AMI), all patients undergoing ECABG without associated procedures at our institution from January 1987 to July 1995 were reviewed. Forty eight patients underwent ECABG after AMI. The hospital mortality rate was 20.8%. ⋯ Univariate comparison of survival curves and coronary event free curves showed that use of SVG alone was associated with decreased survival (p = 0.0009) and event free (p = 0.02) rates. Patients with non-Q-wave infarction and without cardiogenic shock may undergo ECABG relatively safely at any time. The use of internal thoracic artery at ECABG without cardiogenic shock does not increase hospital mortality and improves both long-term survival and freedom from coronary events.

[Emergency percutaneous cardiopulmonary support for patients with cardiac arrest or severe cardiogenic shock].
A total of 20 patients who developed cardiac arrest or severe cardiogenic shock were resuscitated with percutaneous cardiopulmonary support system (PCPS). The etiology of shock was acute myocardial infarction (n = 8), post-infarction left ventricular (LV) free wall rupture (n = 9) and others (n = 3). After successful resuscitation with PCPS, 17 patients underwent therapeutic interventions: either closure of an LV rupture (n = 9), coronary artery bypass grafting (n = 4), percutaneous transluminal angioplasty (n = 1) and percutaneous transluminal coronary recanalization (n = 1). ⋯ Nine patients survived longer than 30 days and 6 patients were discharged from the hospital. In nine patients with LV free wall rupture, one could be discharged from the hospital. Even though our experience is still small in number, it can be concluded that cardiopulmonary resuscitation using PCPS improves survival in fatally ill patients.

Case Reports[Cardiac injury successfully treated by emergency cardiorrhaphy--a report of 5 cases].
Five cases who were successfully treated for cardiac injuries by emergency cardiorrhaphy were reported. The range of the ages of the patients was 14 to 71 years. Four of the 5 were males with stab wounds and one was a 71-year-old female with a blunt injury by motor vehicle accident. ⋯ One was stab injury and the other was blunt trauma. Both of them had an uneventfull post-operative course without any infection. In conclusion, ERT is most helpful when used in the cases with PI* < or = 15. *: physiologic index (Ivatury).

Comparative Study[Comparison of the protective prorerties of St. Thomas', Tyers', and Bretschneider's cardioplegic solutions in the neonatal rabbit heart].
Many studies suggest that single-dose and multidose cardioplegia are protective in the ischemic adult heart, but in the neonatal heart single-dose cardioplegia is only protective, whereas multidose cardioplegia is damaging. We examined three clinically used cardioplegic solutions to compare the protective properties of single-dose and multidose cardioplegia in the neonatal rabbit heart (aged 7 to 10 days). The clinical solution studied were St. ⋯ Among multidose groups, CVR prior to reperfusion was lowest in Breschneider's solution as well. In conclusions, these results confirmed that, using the clinical solutions studied, single-dose cardioplegia provided better functional recovery than multidose cardioplegia in the neonatal rabbit heart. However, low CVR in Bretschenider's multidose cardioplegia suggested the better protection in coronary vasculature although functional recovery was poor.

Case Reports[Case report of coronary artery bypass grafting using only arterial grafts in a patient with idiopathic thrombocytopenic purpura].
The patient was a 76-year-old woman with angina, and diagnosed as idiopathic thrombocytopenic purpura (ITP) by preoperative blood examination. High-dose transvenous gamma-globulin (0.3 g/kg/day) therapy was subsequently conducted for 4 days before operation. ⋯ All grafts were patent and the postoperative course was satisfactory. Arterial grafts may thus be considered suitable for CABG in patients with ITP.
