BACKGROUND The number of patients with longer follow-up after implantation of an implantable cardioverter-defibrillator is increasing continuously. Defibrillation lead failure is a typical long-term complication. Therefore, the long-term reliability of implantable cardioverter-defibrillator leads has become an increasing concern. The aim of the present(More)
We investigated the relationship between factor XIII, fibrinogen, blood coagulation screening tests and postoperative bleeding in 98 patients undergoing cardiopulmonary bypass (CPB) surgery. All patients received aprotinin. Blood samples were collected preoperatively (T1),after termination of CPB (T2),12 h (T3) and 24 h (T4) after surgery to determine FXIII(More)
BACKGROUND The Early Self Controlled Anticoagulation Trial (ESCAT I) showed that anticoagulation self-management after mechanical heart valve replacement decreased complication rates by maintaining INR levels closer to the target range than International Normalized Ratio (INR) home doctor management. The therapeutic range for the INR in that study was(More)
BACKGROUND AND AIM OF THE STUDY Transcatheter aortic valve implantation (TAVI) has been introduced for the treatment of severe symptomatic aortic stenosis in patients not suitable for surgical valve replacement. However, a potential problem of TAVI is the development of severe aortic insufficiency after valve implantation due to a too-low implantation of(More)
This prospective study was undertaken to investigate the response of thallium-201 washout rates to coronary artery bypass surgery. Thirty-four patients with coronary heart disease were studied before and after coronary artery bypass grafting, 27 patients with normal coronary arteries serving as controls. All patients underwent cardiac catheterization and(More)
BACKGROUND Intraoperative blood salvage is an important part of blood conservation efforts in cardiac surgery. The purpose of this study is to examine the effects of three different circuit blood-salvaging techniques: centrifugation, ultrafiltration and direct infusion. METHODS Sixty patients undergoing elective coronary bypass graft procedures were(More)
BACKGROUND Bleeding after open heart surgery is a common but unintended problem, which is unequivocally related to platelet function. The target of our study was to correlate platelet activation levels and postoperative blood loss as well as the predictive power of measurements focusing on postoperative hemostasis. MATERIALS AND METHODS The prospective(More)
Troponin T is a unique cardiac antigen which is continuously released from infarcting myocardium. Its cardiospecificity as a marker protein might be particularly useful in assessing myocardial cell damage in patients undergoing cardiac surgery. Therefore, circulating troponin T was measured in serial blood samples from 56 patients undergoing cardiac surgery(More)
Objective: The pathogenesis of stress ulceration in seriously ill patients is uncertain and the pathogenic role of Helicobacter pylori infection is unknown. We therefore assessed the seroprevalence of patients of a cardiosurgical intensive care unit (ICU) with clinically important stress ulcer bleeding. We compared this prevalence with a control group(More)
