Cardiac surgery with cardiopulmonary bypass provokes a systemic inflammatory response syndrome caused by the surgical trauma itself, blood contact with the non-physiological surfaces of the extracorporeal circuit, endotoxemia, and ischemia. The role of endotoxin in the inflammatory response syndrome has been well investigated. In this report, we reviewed recent advances in the understanding of the pathophysiology of the endotoxin release during cardiopulmonary bypass and the possible therapeutic strategies aimed to reduce the endotoxin release or to counteract the inflammatory effects of endotoxin.

Access through the right superior pulmonary vein is a commonly used route for left ventricular vent insertion. Complex reshaping of the stylet and vent into a certain position or external guidance do not guarantee successful placement. In this article we describe a modified technique where the stylet sets up the position to allow consistent atraumatic advancement of the catheter across the mitral valve.

Transfusion of red blood cells (RBC) and other blood products in patients undergoing coronary artery bypass grafting (CABG) is associated with increased mortality and morbidity. We retrospectively analyzed data of patients who underwent an isolated coronary bypass graft operation between January 1998 and December 2007. Mean follow-up was 1696+/-1026 days, with exclusion of 122 patients lost to follow-up and 80 patients who received 10 units of RBC.

Lipomatous hypertrophy of the interatrial septum is a rare cardiac lesion that is usually limited to the interatrial septum. We report a case of an extensive lipomatous hypertrophy, which protruded into the right and the left atrium as well as the superior and the inferior vena cava and the right ventricle. A 71-year-old woman was referred to us because of a cardiac mass on a transthoracic echocardiogram, performed on a routine check-up because of a known membranous ventricular septum defect.

Transhiatal resection for carcinoma of the distal esophagus is associated with relative high morbidity and mortality. We present a rare case of cardiac tamponade after transhiatal esophagectomy for which emergency sternotomy was performed. Probably the retraction of the heart during exploration of the mediastinum caused a laceration of an epicardial vein.

Background: After coronary bypass surgery, occlusion or narrowing of bypass grafts may occur over time. The present study prospectively evaluated the angiographic patency of bypass grafts after 1 year in relation to the preoperative angiographic and functionally severity of the coronary lesion assessed by fractional flow reserve measurement to test the hypothesis that grafting of less critical stenosis may be a risk factor for early dysfunction of the graft.

Methods: The study comprised 164 patients eligible for coronary artery bypass surgery who were not suitable for percutaneous intervention and with at least one intermediate lesion.

Strategies to reduce blood loss and transfusion of allogeneic blood products during surgical procedures are important in modern times. The most important and well-known autologous techniques are preoperative autologous predonation, hemodilution, perioperative red cell salvage, postoperative wound blood autotransfusion, and pharmacologic modulation of the hemostatic process. At present, new developments in the preparation of preoperative autologous blood component therapy by whole blood platelet-rich plasma (PRP) and platelet-poor plasma (PPP) sequestration have evolved.
