Comparative Study
Long-term outcomes after cardiac transplantation: an experience based on different eras of immunosuppressive therapy.
Constantly changing practices in heart transplantation have improved posttransplant survival in patients with end-stage heart disease. The objective of this study was to evaluate long-term outcomes in different eras of immunosuppressive therapy after cardiac transplantation at a single center during a two-decade period. ⋯ Cardiac transplantation provides satisfactory long-term survival for patients with end-stage heart failure. The improving outcomes in survival correlate with improved immunosuppressive therapy in each era. Although the reasons for improvement in survival over time are multifactorial, we believe that changes in immunosuppressive therapy have had a major impact on survival as evidenced by the decreasing number of deaths due to rejection.

Video-assisted thoracoscopic surgery (VATS) has been shown to be an accurate method for identifying diaphragmatic injuries (DIs). The purpose of this investigation was to establish specific indications for the use of VATS after penetrating chest trauma. ⋯ In the largest published series of patients undergoing VATS to exclude a DI, this review identifies five independent predictors of DI after penetrating chest trauma. A diagnostic algorithm incorporating these five factors was designed with the goal of reducing the number of unrecognized DIs after penetrating chest trauma by using VATS for patients at greatest risk for such injuries.

Venous bullet embolism to the heart is a rare complication of penetrating gunshot trauma. There are little data regarding long-term follow-up of missiles retained in the right ventricle. We report a rare case of right ventricular bullet embolus following a left-sided thoracic gunshot wound. The patient presented with delayed onset of cardiac irritability symptoms 4 years after injury.

Current experimental studies have demonstrated that peroxynitrite (ONOO-) has both cytotoxic and cytoprotective effects on myocardial ischemia-reperfusion injury. However, even myocardial ONOO- formation has not yet been investigated in humans undergoing open heart operation. We measured plasma nitrotyrosine as an indicator of ONOO- formation during open heart operation and examined its association with myocardial ischemia-reperfusion injury. ⋯ These results first demonstrate that ONOO- is produced from human myocardium after ischemia-reperfusion during open heart operation, and myocardium-derived ONOO- can be determined by the CS-Ao difference in %NO2-Tyr.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperatively administered aprotinin or epsilon aminocaproic acid after cardiopulmonary bypass has limited benefit.
Intraoperative antifibrinolytic treatment with aprotinin and epsilon aminocaproic acid (EACA) has been shown to be effective prophylaxis in the reduction of excessive bleeding after cardiopulmonary bypass operations. This study investigated the effectiveness of both drugs when used as a postoperative treatment of patients showing early signs of increased bleeding. ⋯ Aprotinin or EACA administered in the early postoperative period was ineffective in reducing postoperative bleeding with the exception of a small group of patients having valve operations in whom aprotinin treatment may have shown some benefit.
