Late Aspergillus fumigatus endomyocarditis with brain abscess as a lethal complication after heart transplantation.
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. Preceding colonization with Aspergillus spp was not identified. Primary cytomegalovirus infection (donor+/recipient-) and toxoplasmosis reactivation (donor+/recipient+) occurring at 1 and 2 months post-transplantation were successfully treated.

Increased expression of endothelin-converting enzyme-1 in failing human myocardium.
Endothelin-1 (ET-1) is considered to be involved in the development and progression of heart failure. Therefore, we analysed the expression of endothelin-converting enzyme-1 (ECE-1), endothelin receptors A (ET(A)) and B (ET(B)) mRNAs by standard-calibrated, competitive reverse transcriptase-PCR using an internal-deleted in vitro-transcribed cRNA standard. ET-1 peptide levels were measured using isoform-specific rabbit antibodies against synthetic ET-1. mRNA and protein expression was determined in the right atrial myocardium of New York Heart Association class I patients and class IV patients undergoing aorto-coronary bypass surgery. ECE-1 mRNA was upregulated in failing atrial myocardium. Furthermore, ET-1 peptide levels were increased in failing atrial myocardium. Atrial ET(A) mRNA expression was not changed, while ET(B) mRNA was downregulated in the failing atrial myocardium. Our results support an upregulation of ET-1 synthesis by induction of ECE-1 in failing atrial myocardium. Pharmacological inhibition of augmented ECE-1 expression might provide a new therapeutic perspective in the treatment of heart failure.

Proteomics strategies in cardiovascular research.
Cardiovascular research of the past decades dealt with classical pathophysiological descriptions, then shifted toward the identification of relevant receptors, and then proceeded to the analysis of signal transduction pathways. Most recently, hand in hand with the achievements of the human genome project, the research has gone down the road toward molecular biological "disease gene(s) mapping". The application of proteome research will attempt to close the gap between genomic (and genetic) analysis and the physiological research. The rich source of heart surgery specimens represents an excellent starting point in data acquisition of proteomic context. Furthermore, animal models of cardiovascular diseases and deficiencies are considered, and will be explored. Examples of results from feasibility studies are given, with the emphasis on quantitative evaluation of proteomic components, hoping to discover co-regulated sets of proteins that are involved in any particular disease state. Identification of new, not yet discovered proteins will be pursued, though the emphasis of this work will be on the definition of characteristic sets of expressed proteins, which in turn might be able to delimit the state of disease and prognosis of therapy outcome. Besides the systematic issues, this paper refers to a number of methodological questions, like the comparison of the proteins detected by staining procedures and proteins detected in models in which biosynthetic labeling is applicable.

OPCAB surgery after right pneumonectomy.
Coronary artery bypass grafting was performed in a 58-year-old patient 3 years after right pneumonectomy for nonsmall cell lung cancer stage IIIa. The CT scan demonstrated a marked shift of the mediastinum into the right chest, but revealed a feasible access to the left coronary artery by median sternotomy. Pulmonary function was impaired. Off-pump coronary artery bypass grafting was performed to avoid cannulation under more difficult conditions and to prevent negative side effects of cardiopulmonary bypass to the pulmonary function. The postoperative recovery was uneventful. We discuss issues related to this special subgroup of patients.
