Conventional reoperative coronary artery bypass grafting using cardiopulmonary bypass carries relatively high mortality and morbidity. ⋯ Reoperative coronary artery bypass grafting without cardiopulmonary bypass has acceptable early and midterm outcome, and should be considered a viable alternative for properly selected patients.

We describe a device for coronary artery stabilization during minimally invasive coronary artery bypass grafting performed without cardiopulmonary bypass via a small (8 to 10 cm) left anterolateral thoracotomy. This device facilitates the anastomosis of the left internal mammary artery to the left anterior descending coronary artery on the beating heart. The device consists of a simple coronary stabilizer mounted on a wound spreader. We have used this device successfully in 35 primary minimally invasive coronary artery bypass grafting operations.

Randomized Controlled Trial Comparative Study Clinical Trial
Effects of diltiazem versus digoxin on dysrhythmias and cardiac function after pneumonectomy.
This prospective study was designed to determine whether diltiazem is superior to digoxin for the prophylaxis of supraventricular dysrhythmias (SVD) after pneumonectomy or extrapleural pneumonectomy (EPP) and to assess the influence of these drugs on perioperative cardiac function. ⋯ Diltiazem was both safe and more effective than digoxin in reducing the overall incidence of SVD after standard or intrapericardial pneumonectomy. Digoxin therapy had no effect on the incidence of postoperative SVD and is not recommended for prophylaxis of SVD. Dysrhythmias after pneumonectomy or EPP occur in older patients and are associated with a greater length of hospital stay.

Randomized Controlled Trial Clinical Trial
Cardiac enzymes and autotransfusion of shed mediastinal blood after myocardial revascularization.
Autotransfusion of shed mediastinal blood reduces blood requirement after coronary artery bypass grafting. Recently, two nonrandomized trials indicated that autotransfusion elevates the levels of cardiac enzymes after cardiac operations. ⋯ Postoperative autotransfusion of shed mediastinal blood causes elevation of cardiac enzyme levels after coronary artery bypass grafting.

Perfluorocarbon emulsion has proved beneficial in the prevention and amelioration of experimental air embolism. We examined whether the addition of perfluorocarbon to the prime solution could lead to a reduction in the incidence and severity of neurologic injury after the formation of a massive air embolism during cardiopulmonary bypass. ⋯ The addition of perfluorocarbon emulsion to the cardiopulmonary bypass prime solution leads to a reduction in the incidence and severity of neurologic injury after the formation of a massive air embolism during bypass.
