Preamble Guidelines and Expert Consensus Documents aim to present all the relevant evidence on a particular issue in order to help physicians to weigh the benefits and risks of a particular diagnostic or therapeutic procedure. They should be helpful in everyday clinical decision-making. A great number of Guidelines and Expert Consensus Documents have been(More)
Aortic dissection is a rare but potentially fatal event resulting in separation of the layers of the tunica media by ingress of blood, producing a false lumen with variable proximal and distal extension. Ascending aortic dissection is the most common catastrophe of the aorta; it is 2–3 times more common than rupture of the abdominal aorta. Mortality of(More)
BACKGROUND Intramural hemorrhage (IMH) was recently identified at necropsy and anecdotally in vivo as a unique aortic syndrome (without entry and with no flap-like intraluminal component, such as overt aortic dissection). However, little is known about diagnosis, prognosis, and outcome of IMH. METHODS AND RESULTS Between 1983 and 1993, 360 patients from(More)
BACKGROUND A systemic inflammatory response after open heart operation may be responsible for hyperdynamic circulatory instability and organ dysfunction. To what extent mediator release is involved needs to be clarified. METHODS Ten patients with postoperative hyperdynamic circulatory dysregulation (group I) requiring application of alpha-constrictors and(More)
BACKGROUND Chronic heart failure is characterized by left ventricular remodeling and reactivation of a fetal gene program; the underlying mechanisms are only partly understood. Here we provide evidence that cardiac microRNAs, recently discovered key regulators of gene expression, contribute to the transcriptional changes observed in heart failure. METHODS(More)
RATIONALE The use of extracorporeal membrane oxygenation (ECMO) in patients who are awake and spontaneously breathing may represent a novel bridging strategy toward lung transplantation (LuTx). OBJECTIVES To evaluate the outcomes of patients treated with the "awake ECMO" concept as bridge to transplantation. METHODS We performed a retrospective,(More)
A total of 135 survivors of surgical treatment of aortic dissection was followed for up to 15 years after surgery. Actuarial survival rates were 82 +/- 4% at 5 years and 64 +/- 6% at 10 years. There were no significant differences in long-term survival rates of patients in four subsets based on type and acuity of dissections. The incidence of late(More)
OBJECTIVE The aim of our study was to analyse the single-channel properties of L-type calcium channels from failing human heart and to compare them to the respective animal data. Furthermore, we intended to evaluate the feasibility of future single-channel studies on the role of calcium channels in the pathophysiology of heart failure. METHODS Single(More)
Detergents are powerful agents for tissue decellularization. Despite this, the high toxicity of detergent residua can be a major limitation. This study evaluated the efficacy of detergent removal from decellularized pulmonary valves (PVs) and the consequences of repopulation with human endothelial cells (HECs). Porcine PVs were treated with 1% sodium(More)
When designing an extracorporeal hybrid liver support device, special attention should be paid to providing the architectural basis for reconstructing a proper cellular microenvironment that ensures highest and prolonged functional activity of the liver cells. The common goal is to achieve high cell density culture and to design the bioreactor for(More)
