Cardiac efficiency during coronary occlusion and during reperfusion after emergency revascularization under cardioprotection.
Myocardial infarction in consequence of a coronary artery occlusion presents a serious problem. It is the aim of any emergency revascularization to minimize the ischemia-induced damage or to salvage reversibly injured myocardium. In experiments on 8 anesthetized pigs, myocardial protection by orthograde perfusion with a high-volume cardioplegic solution was studied under controlled conditions. ⋯ During the entire reperfusion the myocardium was stunned, i.e. cardiac work was decreased at maintained MVO2. Thus, external efficiency was decreased. From these results we conclude that in reperfused myocardium after cardioplegic arrest, the oxygen is only inefficiently converted to develop force.

Case ReportsCarinal reconstruction under veno-venous bypass using a percutaneous cardiopulmonary bypass system.
We report two patients who underwent carinal resection and reconstruction for advanced lung cancer under veno-venous bypass. The bypass system consisted of a centrifugal pump and a hollow-fiber membrane oxygenator, and was established by percutaneous insertion of cannulas through the femoral veins using the Seldinger technique. This respiratory support system under veno-venous bypass was safe and useful for carinal reconstruction, providing a good visual field and adequate oxygenation. Although other standard accepted ventilation techniques can be used for carinal resection, veno-venous bypass is an alternative adjunct in cases involving difficult carinal reconstruction.
