The M1 muscarinic receptor antagonist pirenzepine in low doses decreases resting heart rate; this effect declines with age (Poller, U., G. Nedelka, J. Radke, K. Pönicke, and O.-E. Brodde. 1997. J. Am. Coll. Cardiol. 29:187-193). To study possible mechanisms underlying this effect, we assessed (a) in six young (26 yr old) and six older volunteers (61 yr(More)
We report the case of a 65-year-old male patient who died from lethal Aspergillus fumigatus endomyocarditis and multiple cerebral septic emboli 6 months after cardiac transplantation. This complication developed 4 weeks after diagnosis of bilateral pulmonary aspergillosis, which was immediately treated by surgical removal and intravenous amphotericin B.(More)
OBJECTIVES To determine the difference in sternal infection and other infectious events between conventional wire and cable-tie-based closure techniques post-sternotomy in a collective of patients after cardiac surgery. METHODS The sternal ZipFix™ (ZF) system consists of a biocompatible poly-ether-ether-ketone (PEEK) cable-tie that surrounds the sternum(More)
An increasing number of aortic valve replacements are performed through a ministernotomy. Due to the small incision and partial fixation of the caudal sternum, the traditional wire closure can be complicated and even harmful to the surrounding tissue. In such cases, we recommend the use of nitinol clips for sternal closure. This technique, which we have(More)
Myocardial ischemia during cardiopulmonary bypass terminated by reperfusion generally leads to different degrees of damage of the cardiomyocytes induced by transient cytosolic Ca(2+) overload. Recently, much attention has been paid to the role of heart-specific Ca(2+)-binding proteins in the pathogenesis of myocardial ischemia-reperfusion injury. S100A1 is(More)
OBJECTIVES We investigated the impact of mechanical unloading with a left ventricular assist device (LVAD) on the myocardial proteome. METHODS We collected 11 patient-matched samples of myocardial left ventricular tissue of patients with non-ischaemic dilate cardiomyopathy, harvested at time of LVAD implant ('pre-LVAD') and heart transplant ('post-LVAD').(More)
OBJECTIVE One of the most important factors in bypass surgery is the preservation of endothelial function in the arterial graft. It was of interest, therefore, whether a slightly modified preparation procedure during surgery could contribute to improved endothelial function of the graft. We compared the functional activity of internal thoracic arteries(More)
Objectives We hypothesized that antegrade open stent graft implantation in the descending aorta during acute type A aortic dissection surgery is safe and improves patient outcome compared with the standard repair technique. Methods Hundred and forty-one consecutive patients underwent surgery for acute type A aortic dissection at our institution from 2010(More)
A36-year-old woman with a 3-week history of shortness of breath was admitted to the hospital after having suffered syncope. She also complained of left-sided leg pain. Duplex ultrasound revealed a right-sided proximal deep venous thrombosis and an occluded left popliteal artery. Echocardiography demonstrated a dilated right ventricle and tricuspid(More)
