BACKGROUND Complement activation contributes to ischemia-reperfusion injury. Patients undergoing thoracoabdominal aortic aneurysm (TAAA) repair suffer extensive ischemia-reperfusion and considerable systemic inflammation. METHODS AND RESULTS The degree and mechanism of complement activation and its role in inflammation were investigated in 19 patients(More)
BACKGROUND The purpose of this study was to investigate the cytokine and chemokine profile in low-risk patients undergoing off-pump and on-pump coronary artery bypass grafting (CABG) surgery by use of a broad panel of cytokines and chemokines. METHODS Eight consecutive blood samples were obtained from patients enrolled into a prospective, randomized study(More)
AIMS Transplant-associated coronary artery disease (TxCAD) is a major cause of post-transplant graft failure. The aim of this study was to investigate a possible role of mannose-binding lectin (MBL) deficiency and complement activation in TxCAD. METHODS AND RESULTS In a prospective study of heart transplant recipients (n=38) with a follow-up of 5.3+/-1.3(More)
BACKGROUND Atrial fibrillation is the most common rhythm disturbance encountered after open heart operations, with a reported incidence up to 40%. Despite its high incidence and clinical relevance its etiology remains obscure. It has been hypothesized that atrial fibrillation might be related to extracorporeal circulation. We performed a retrospective study(More)
The crucial role of complement and naturally occurring anti-Gal antibodies in hyperacute rejection of pig transplants to Old World monkeys, apes and humans is well established. This rejection can be prevented by manipulating either system. Although cells, tissues or organs from pigs made transgenic for human complement regulatory proteins escape hyperacute(More)
BACKGROUND The aim of the study was to evaluate our clinical experience with the CarboMedics Heart Valve Prosthesis. METHODS Nine hundred ninety-seven consecutive patients underwent mechanical valve implantation (aortic, 771; mitral, 169; double, 52; tricuspid, 5) with this prosthesis from September 1987 through December 1993. The mean age was 62.3+/-13.7(More)
Proliferation signal or mammalian target-of-rapamycin inhibitors (PSI/mTOR inhibitors), everolimus and sirolimus, provide attractive options for use in heart transplantation because they are immunosuppressive and anti-proliferative. PSI/mTOR inhibitors work synergistically with calcineurin inhibitors (CNIs) and thus permit the minimization of CNIs without(More)
Limited information exists about acute renal failure (ARF) early after heart transplantation (HTx). We correlated pre-, per-, and post-operative patient and donor parameters to the risk of developing ARF. We also analyzed the consequences of ARF on kidney function after HTx, risk of later need for chronic dialysis or kidney transplantation, and mortality.(More)
BACKGROUND The post-market Registry to Evaluate the HeartWare Left Ventricular Assist System (ReVOLVE) is an investigator-initiated registry established to collect post-CE Mark Trial clinical data on patients receiving a HeartWare ventricular assist device (HVAD) in the European Union and Australia. METHODS The ReVOLVE is a multi-center, prospective,(More)
